This is the latest installment in the blended research at the library multi-disciplinary perspectives for everyone. Discussion series and we have a good program here today. I imagine and many of you are know some of the speakers but we have three good speakers for a panel and only introduce them in just a minute the nuclear debate has always been a heated one. How safe is it where the positive and negative environmental effects of nuclear energy when compared with other energy sources the disastrous effects in the Fukushima nuclear plant in Japan following the earthquake and tsunami have heightened concern over the safety of nuclear energy as you can and you'll tell or are three speakers are very highly qualified to talk about this topic and it will be quite interesting. We're going to follow the format that we've used in our previous blended research at the Library series each of our speakers will present Bill talk to us for somewhere between fifteen twenty minutes and then after all of them are presented we'll go ahead and have a question and answer period where you can ask questions and and they'll give us their sage answers on that image tween the first couple speakers because will be switching off of the laptop we're going to have our door prize then. And so I hope everyone. Intrade their ticket into the drawing and will give out. We have a book or some computer programs that that you can get I'll go ahead and introduce our speakers in the order that they'll be present presenting to us. First we'll hear from able he's a Ph D. student in nuclear and radiological engineering here at Georgia Tech. He's pursuing and he's also pursuing a graduate certificate in public policy. He graduated from the University of Wisconsin Madison in one thousand nine hundred nine with a B.S. in him innocent nuclear engineering kills primary reach. Search interest is an identifying problem areas in the macro economy such as securing it to secure and sustain energy supply and creating integrated engine hearing solutions addressing these problems within the constraints of existing policy infrastructure technology and finance his Ph D. is is focused on adapting solar thermal energy storage methods to fourth generation nuclear reactors as a way to limit regulatory boundary of the Nuclear Regulatory Commission without endangering the public. Tim Cahill is a graduate student in nuclear and radiological engineering. Also here at Georgia Tech. He's currently pursuing his master's degree in nuclear engineering under the direction of doctrinal and hurdle he received his B.S. in nuclear and radiological engineering from Georgia Tech in two thousand and ten in terms area of research is radiation detection with a particular focus on neutron detection using banner spheres. He has also participated in research first. And the Centers for Disease Control involving the use of portal monitors and devices determining internal can. Contamination levels during a radiological event such as the detonation of a radiological dispersal of a device or the release of vision products from a nuclear reactor accident that the information garnered from this research was applied to assist in the relief efforts at Fukushima Dai ichi in the days following the reactor accident in our concluding speaker file speaker will be Dan Taylor Dr Taylor is an associate professor emeritus of chemical and biological engineering here at Georgia Tech. He's an also an adjunct faculty member of the school in mechanical engineering he retired from the school of chemical and biological molecular engineering in December of two thousand and six from April of two thousand and seven until March of two thousand and eight he served. At the Nuclear Regulatory Commission in Rockville Maryland as a senior chemical process engineer. He attended Kenyon College and received his bachelor's a chemical engineering from Georgia Institute of Technology. He obtained is innocent. PH degrees in chemical engineering from the University of Wisconsin in Madison where he's also a big U.W. fellow go back years prior to joining the faculty at Georgia Tech he was a staff engineer in the chemical technology division of Oak Ridge Oak Ridge National Laboratory in Tennessee where he developed a managed an experimental program to demonstrate act act and I partitioning flow sheets for radiological waste management and advanced concepts for reducing long term radio talk sides of high level waste at Georgia Tech. Dr Taylor had continued his research in radioactive and chemical waste and chemical waste management advanced chemical separations and process invention. He holds seven patents and has over seventy technical publications. He was a senior series editor at the radioactive waste management handbook and former executive editor of toxics toxic and hazardous substance control in part of the Journal of Environmental Science and Health Care with no further if you will go ahead and have a presentations. Thank you so much. I mean probably a title and found a bit of the humor in there. So why as a farm kid from Wisconsin who when the first time I saw a nuclear reactor. I was scared my life I thought I was going to die. Remember seeing it and I was really possessed by that fear and. That fear motivated me to pursue my degree in nuclear engineering and as I learned more about nuclear power. I came to appreciate what the real value that nuclear energy has for this is for our society. So if there's one thing that you take away from from this discussion. Is Don't let your fears govern your life address your fears with knowledge and study and effort and you can discover a whole nother world that you didn't even know existed. So my talk today is more on our nation's energy supply. So I'm going to be talking about a good bit of politics some nuclear weapons because you can't ever seem to get away from those things and of course the costs and what a different power supply options are we face a whole series of problems in our world. Most notably the emissions of carbon dioxide. We also import a significant portion of our primary energy from overseas. And this exposes us to a significant amount of risk to supply chain disruption is a majority of the world's oil but roughly a third of the world's oil goes through the Straits of Hormuz. And if you haven't been watching the news our Iran or the regime in Iran doesn't particularly like us so. They're also having a few building nuclear weapons and delivery systems and don't seem to have a tremendous amount of respect for human life. The combination of nuclear weapons and a lack of respect for human life is a dangerous dangerous combination all respect in our country of human life is what prevented us from using nuclear weapons more in the Cold War And I think is vital for the future of our planet but more back to the Gulf. This seems to be the hot bed of of modern society and we have even more problems. And there are like Saudi Arabia overstating their oil reserves and I was exposed to this Pekoe model and by my own Evan Hakon. I thought it was quite quite taking what does it mean being at peak oil and so I built a physics model of what the world's oil supply and integrated price with it and that's what my who I was based off of in a text with what the Energy Information Agency says on their green line the high one which is the high oil model and then the kind of Ornish line is the reference case scenario and this is your store data. Well if you lived through the one nine hundred seventy S. And I sort of vaguely remember this is the supply shortages that we had during the Iranian revolution with the gas lines and the last time that we had gas lines I was deployed so my wife was sure to tell me about that in and the e-mails as I was out on the other side of the world. So we can't approach these problems individually we have to look at these problems more holistically and understand what the real issues are and to start that I looked at what the costs of producing electricity are this is a vocal unit three and four being constructed it's going to be coming in around ninety ish dollars per megawatt hour. And that's a good number for to have in the back your mind for what the level ice cost of nuclear power is and I thought things were going wonderful and then this wonderful day in in March I heard about this in Japan where sixteen thousand people are dead and four thousand people are still missing nine months after the tsunami and the impact that that had on Fukushima Daiichi it was immense the wall of water was over forty five feet tall it inundated the facility. It took up all power we rely on electrical power whether small offsider from diesel generators to provide cooling for the reactors. Well they basically lost cooling and were unable to operate any valves in sufficient amount of time to prevent these events from happening. So what was a loss of life that occurred from this zero most challenging beyond design bases event that we could even not even think about because in resulted in the loss of their lives. So as a result of this immense demonstration of safety. The German people are moving away from nuclear power as a whole slew of other countries and that's placing stresses on other sources like the price natural gas price natural gas is skyrocketing around the world. The only reason why it's so expensive here is because we have hydraulic fracking and seem to be getting a lot of it from the ground at least for the time being so natural gas. When it comes to producing electricity natural gas. Even at its low bargain basement price comes in about ninety eight dollars from a go out from a watt hour for advanced combined cycle plant. So this is the best that natural gas can do with the cheapest fuel fuel price goes up price of electricity goes up but we do have a lot of natural gas and ground out thirty one terawatt years which gives us about one hundred years at current consumption levels and fortune natural gas in how we produce it at least with existing technology produces twenty percent more greenhouse gases than coal so natural gas is not some clean savior coming along. It's another technology with its own problems just like everything else. Now as far as providing energy security these dark blue lines are how much natural gas we import this is from MIT. The report on the future of natural gas. This is twenty twenty stone here about two and then by two thousand and fifty. It's up around fifteen. So we go from the frying pan into the fire. If we rely on natural gas. It's only a matter of time so we need to demonstrate a little bit more forethought in. What we're doing with our sources of energy wind. Somebody might look at that number and go you I know I don't why I didn't include any subsidy costs. So the numbers that you see up here are just a straight numbers. So no subsidies. No incentives. Because remember subsidies have to be paid by somebody. The cost of building these has to be paid by somebody whether it's the people who is buying electricity or whether it's by taxpayers somebody paying for it. So if we're going to look at these this terms of what the impact is on the economy. Don't call it the subsidy. The other thing that when his is wind is fickle. So you have to back up wind power. So I backed up wind power my model with natural gas and that's reflected in this price because our economy relies on having electricity when we want to electricity and the cost of having the lights go out. When you don't want the lights to go out is immense. And then this this occurred to me when I was in the Navy is all right we have all these wonderful coal plants and since nuclear power is only a fancy way of boiling water. What if we just changed out the heat source. We convert all these coal plants that we have around the country. To nuclear reactors by just changing out the heat source and tie the reactor in with the steam plant. So we minimize and reuse and actually continue using our existing energy infrastructure then using this Rick technology this is a General Electric's prism designed to sodium fast reactor it comes in about ninety dollars from a go on our right on par with what you'd see with existing nuclear power plants. I chose this technology because we operated a prototype for a good number of years and the main reason is that it had this passive safety demonstration or inherent safety demonstration they challenge the reactor and ran an experiment on it. The see what would happen with really insane conditions and the reactor was able to demonstrate that it could protect itself for a week or so week without any operator action and a week without electrical power. Keep in mind to restore power to Fukushima took nine days. So being able to keep the fuel completely intact in the reactor intact after a week to big deal is this a safe plan the reason why I like it is it's hot. But five hundred degree Celsius and the technology is ready in about the next decade and that's two for the combined construction operation license. So this is the most mature advanced reactor technology that's available. The reason I like is the fuel. The fuel is very easy to make it's actually made on site at last for a long time. It's very resilient fuel wonderful stuff and it's recyclable one hundred percent recyclable. And it's designed for being recycled and the best part about it all as that you get to use nuclear weapons to make electricity. I don't like nuclear weapons very much. So any time I get to turn those into electrons going down the wire that makes me very happy that we do this is a continuation of existing policy with the Megatons to Megawatts. So this is not a new idea. The only reason why I like it is that it's not big it's not a massive capital investment it's not a thousand megawatt plant it's about three hundred megawatts. So it's smaller. And the mission that we have before going to these coal plants is a complex mission all around the country we can repeat our seventy five percent of the coal plants using existing regulatory framework that's a non-trivial number of plants and the. Level of reusing our existing infrastructure. So we need a reactor that's resilient we need technology that can adapt and can operate in many different situations because the work that we have to do. Of closing this carbon dioxide emission gap of the top one saying this is where we're going and then this is seen this is where we want to go way down there. That's a big difference. And we need something that can tackle that. So I looked at what conventional wisdom was I looked at what we what our power look like if we did it with renewable energy and. The top line up here. This is with the carbon dioxide tax and we do nothing to change our energy infrastructure. So this is we tax carbon dioxide and sit on our hands and see what happens then the next the green line this is a renewable line. So the price goes up and doesn't really stop going up and then this white line down here is if we do nothing which is basically what we're doing right now. So that's the bottom line right here the other thing that I saw with this is that your carbon dioxide emissions from new a bull's eye go down and then they start going back up and the reason why they start going back up is that we have to back up renewable power. In order to maintain the stability of our grid. Think of maintaining stability of the grid as maintaining stability of our economy. It's important it's that important. So renewables won't get you so far they're not good enough and this red line is the is the target and this is eighteen eighteen percent or twenty percent reduction. Now renewables short a non-trivial amount in our carbon dioxide emissions by twenty fifty Not only that we was a lot of land to the tune of the air. The size of Minnesota. So what about doing something different. Well here is kind hard to see this is coal and you'll notice that coal is phased out by about twenty thirty five. We're not using coal that is like Christine twenty thirty five and we've done it by converting all those coal plants around the country to nuclear reactors and here's what happens with the prices a little bit more expensive initially but once you stop having to build so many nuclear plants so fast the cost of electricity falls and by twenty fifty five. It will be back to where we were if we did nothing when US year that your carbon dioxide emissions go down to ten percent by twenty thirty five. So we're well below the twenty percent reduction by two thousand and fifty line that was proposing legislation. So this gives you a whole bunch of credits to offer carbon dioxide offsets to limit the overall cost the economy. Now we all know that coal pollutes and this is what the cost of coal is on the economy is what I'm right here. So the overall cost the economy by going nuclear is less than what it is now. Now the problem with coal is actually I don't have a philosophical problem with coal I actually kind of think it's a neat neat chemical product it's fixed carbon wonderful stuff that some people really depend on it for their livelihoods. So are all these obsolete is our entire fossil fuel infrastructure obsolete and we've got about one point three trillion dollars invested in our fossil fuel and infrastructure we don't have enough money to be able to walk away from that investment if we're going to do and take meaningful action in reducing our carbon dioxide emissions. We have to find a way of reusing this infrastructure. Of continuing the use of armed minds fifty billion dollars invested and that's not even counting the value to the economy of the employment and in Appalachian in Wyoming. I understand why the president is advocating pushing offshore drilling exploring up in ANWAR look at who has the oil the what's the risk that we expose ourselves to this is last year. Well almost two years ago now that this is the spill from the Deepwater Horizon. We do have other options like Keystone X.L. But what's the environmental damage that those are going to inflict up in Canada or North Dakota. But what's the cost of doing nothing. What's the risk that we in we in tail or incur if we do nothing do to address peak oil. There's another way of doing this and of continuing the use and that's to convert coal into liquid fuels and how the very model in World War two was able to get the lift off up in the air. It was how South Africa was able to get through the oil embargo in the one nine hundred eighty S. The process is officially process. There's a lot of different ways of doing it. That's one of them. So we take the coal at some he turn it into diesel and gasoline. So we continue using of our existing fossil fuel transport transportation infrastructure both coal and liquid. And get to keep our cars we continue use of our coal mines. We even get to continue the use of all the coal handling facilities and all those coal plants that we were powered because we're going to use some of the heat from the nuclear reactor to liquefy that coal. So we're going to turn our coal plants into power plants. Not only power. As for electricity power plants for transportation infrastructure and because we're using the prism design which is based off the Integral Fast Reactor we open ourselves up to a massive supply of fuel. These are uranium hexafluoride casts of depleted uranium in think there's a to do go into and we've also got a whole mess of them up in Piketon think somewhere in the world of one hundred thousand and this room would be filled by four of them. So think about that for the size of these as far as how much energy we have in here is a lot we don't even have to dig in the ground. We have so much of this waste a lot of waste spent fuel is perfectly good fuel we recycle this fuel we reduce the waste volume by ninety five percent. We put that those act nice enough plutonium back in the reactor and use those perfectly good fuel perfectly good fuel we reduce our nuclear waste liability from hundreds of thousands of years to three hundred years good fuel why throw it away. So back to carbon dioxide emissions one of the first things that got me started on this if we replace baseload power with nuclear. Maybe ten percent twenty percent. If we replace load following or an immediate load with nuclear power nuclear process eat if we shift our industry to nuclear power where we got the hotter reactors now we cut our carbon dioxide almost in half the coal to liquids actually reduces our carbon dioxide footprint might seem like it doesn't but it actually does because we're adding energy on per mass of the coal from the heat from the reactor. So we're fixing carbon free heat in the coal. And that actually reduce our overall carbon dioxide emissions. So far here. We've increased our primary energy consumption and reduced our carbon dioxide footprint. So to get to the eighty percent reduction in two thousand and five levels. The only place where we have left to look is to improve vehicle efficiency because the only place that we're using carbon in our economy in case you've been missing the news or close your eyes every time you want or drive by the gas station or pump gas which I do actually I don't want to look at it any more because it's pretty depressing. It's now this is not a esoteric intellectual concept the problem is now which means that we have to find and develop solutions. Now we need energy and lots of it and coal liquids and repairing those coal plants with nuclear reactors is an efficient and fast way of reusing our entire infrastructure so targeted capital investment big bang for the buck and we need everything in everything including the kitchen sink just be smart about what technologies we pick. Thank you. All right. Good afternoon everybody. My name is Tim Cahill and I'm here on behalf of the nuclear and radiological engineering department sort of that. Forgive me if I have to pause during the presentation I'm kind of recovering from a little bit of a sickness. So bear with me and I want to start off by saying that my approach to the future of nuclear power is as our other panelists I'm sure to attest to based on my experience and as such I don't have a very broad experience yet in the nuclear industry. So I'm going to speak on what I know about which is education. Having been near lifelong student. So I believe education is very important in nuclear power which is why I chose this title a brighter future and I did intend a little bit of a pun there in general I think the future for nuclear power is very bright how bright that future is I believe depends very much on education. So where do we stand currently in the world when concerning energy and energy usage. Well just some very general numbers here we've got approximately one point three billion people in the world who live day to day without electricity. That's twenty percent of the world's population and this is a map it's kind of hard to see but this is a map of the world that night you can kind of clearly make up the US there Europe parts of Asia Japan especially some parts of China pretty much Africa is completely dark. That's where the majority of that population lives Africa actually is the second most populous continent on the planet and so you know there's a lot that needs to be done to ensure energy equality on a global scale. It's interesting things to note you know we've been going through this economic depression it's worldwide recession excuse me not oppression. I don't think we're there but a global economic downturn. If you will. What's interesting to note about this is that last year from two thousand and nine to two thousand and ten energy demand actually increased by over five percent that's good news and bad news in a sense good news is that you know energy is still growing bad news is our economics aren't such that it's becoming more and more difficult to contain. To supply that demand. You'll notice here that the majority of the growth. I don't know about is playing. OK majority of the growth is occurring in Latin American countries as well as Asia and China specifically is making huge leaps and bounds in deploying new sources of energy at the same time energy intensity works and again thank you. Spencer one of my research team mates. This is energy intensity you can think of this as a measure of a fish and see how efficient. Are we with our energy as a measure of a part of our G.D.P. So we're actually becoming less efficient the majority of the world is becoming less efficient in its use of energy per G.D.P. The exceptions again are Asia here Africa I would say there is so little use of power there that it's very difficult to determine that. But Asia. What's going on here is China is having this positive effect on efficiency because of their deployment of so many nuclear new nuclear power plants so that that affects you know Asia's rate ratings there. So what does this mean what's in store for us here in the next. Let's say twenty twenty five years. Well it's not a very pretty picture. According to one of the latest reports released this was released by the International Energy Agency. It was the world energy outlook for two thousand and eleven this report actually was really released on November ninth so last week there was a big article in The New York Times about it and they're heading there pretty negative outlook here on our radar viciously more expensive energy and that was a major address. Addressing point in this was because of the lack of nuclear power because of the predicted decreased support and implementation of nuclear power. So what happens in twenty thirty five according to the Energy Information Agency. Well energy demand is going to increase by nearly a third of what it is today that would be in other words that would be essentially like adding two more United States to the world in terms of demand. So imagine three times what our demand is right now being added to the world in twenty five years. That's a lot. We are the second largest consumer of primary energy in the country or in the world right behind China at this point. So it's a lot that we're going to have to accommodate here. C O two emissions from energy are going to go up by twenty percent. I think wherever you stand on the global warming debate. I think we can all agree that this in general isn't a good thing. Regardless and the the I believe that this is going to lead to global temperature rises of three and a half degrees Celsius. So all of this spells not a very pretty picture for things to come makes it more difficult for us to grow economically as Cal mentioned as been that's being you know one of these fundamental things that we as a global community need to achieve and I want to say that this this model that the I I. The a scuse me implements implements a seventy percent growth in nuclear capacity. So there is a significant growth in nuclear power. But what's the problem then why why why are we still having these problems or to ask it another way. Why aren't we. Implementing nuclear given all of a. Benefits that have been previously discussed why aren't we. Implementing this you know why is this such a big deal. Well summarize it and also get a chance to practice Spanish no comparable I do not comprehend it. I think that really describes the problem in a nutshell the majority of the public at large just simply does not understand what nuclear science and technology is all about. They don't understand how a nuclear power plant works. What radiation is how we use radiation the fact that radiation exists. Naturally it's not some human monster that we've created it's always been here and always will be here. Those are our numerous kinds of points that really need to be addressed in order for nuclear to be a considerable part of the future and to kind of give a reason why I think this becomes a problem is that as commented earlier fear of the unknown. It's a very real thing and it's something that isn't just unique to the nuclear industry it's been a problem throughout human history and in a lot of cases it's led to a lot of very destructive and the things within society the body remember Salem Witch Trials fear of magic let that burning at the stake of many people. Luckily as far as I know no nuclear scientists or engineers have been burned at the stake yet so I don't think we're quite at that level but given the consequences and given the projections of the future. I'd say the costs are pretty great. And we need to address that. So what's the solution. Well to borrow a Latin maxim science potentia not knowledge is power and I mean this in more than one way you know beyond just you know. Powering electricity informing people and giving them knowledge empowers them to make logical decisions to fight off fear of the unknown and to really come to solid conclusions that benefit society as a whole so to kind of go into why I think education is the solution I mean it kind of sounds. I don't know a little little silly right. The key to manage created public is to educate them. Well there's some reasons why I think this is the case and one particular that I would like to kind of point out is a study that was done in two thousand and nine by this county research about public support of nuclear energy. The survey was done kind of in two parts the first part was discussing public support of nuclear energy on the whole of the U.S. So hey here's a random sampling of the U.S. and we're going to ask you some questions. You know do you think it's important for future you think we should renew licenses at current plants do you favor nuclear energy. These are all kind of yes or no like or dislike questions do you think we should build new nuclear reactors and if we if you do think that would you be happy with that being built at the site closest to you in this case the numbers were pretty positive. This may have changed after Fukushima in fact they've suspect it does but the point that I'm trying to make with this is actually present in the next slide and that was the second part of this survey the second part was to survey a group of people called nuclear power plant neighbors. These are people within very close proximity of nuclear facilities. These are people that directly see the impact of nuclear power nuclear energy on their daily lives they see it driving back and forth to work. They may work there. They may know friends of people that work there. They see the impact directly in their day to day lives and in every single case. The support of nuclear energy was greater for all of these questions asked for people that lived in close proximity that had an understanding at least cursory of what nuclear power is so the point I'm trying to make here is that education does indeed I believe but lead to a better understanding and therefore greater support of a technological technology that has so many great potentials. So a little bit about my personal experience and maybe some possible insights on how to actually go about educating I'm twenty three years old and I am happy to say that I have been employed in the same industry for nearly twenty years and it guesses on what that is a student. I've been an education for nearly all my life. It's what I know and it's what I plan to speak your today about. So one of these goals in the last five or six years that I've kind of found as I've worked with various groups the American Nuclear Society students on campus whatnot and a variety of outreach programs is that when you're trying to educate people you need to figure out number one what your audiences and to do this is officially as possible. You want to target the largest audience that you can and at the same time deliver information in the most efficient method possible. The second part's a little tricky because you as has been witnessed in the nuclear industry. We've had some trouble relaying information in a way that makes sense in a way that that truly benefits the public a lot of our major incidents in the nuclear industry those crunch times you know where we really need to do well on this. We haven't done so hot. So it's very difficult to find a way to present information that isn't too over the top over everyone's head and at the same time make sure the information isn't condescending to somebody that they aren't going to be turned off. Whatever with it but I think I've kind of found a way around this to an extent and that's by really selecting carefully who your audience is and in my case my experience has been to select kids. Number one they're WAY smarter than most people give them credit for as I've come to find we've done numerous outreach activities through N.-S. This Is Us at Earth Day here at Georgia Tech as well as a few the the complementary or cursory glamour shot there of me at the Fernbank Museum during a boy and girl scout day. And we've we've targeted kids from five and six year old students all the way up to high school physics A.P. physics students. I think this is the best audience target number one there's a lot of kids globally. It's actually one of the largest groups of people currently existing on this planet are between the ages of fourteen and twenty one. So that's a huge huge audience and the bonus about this audience to get parents to I didn't think about this when we first started this but this is what's really key is that I was amazed at how much kids knew already about nuclear science and technology and at the same time I was amazed at how little some of the parents know what's great about picking kids as your target audience is that you pick an an age level where disseminating very simple topics in very simple concepts is easier. It's very if you can explain something to a five year old child. You can explain it to anybody but what's great about this is that an environment where you have your actively engaging children is that their parents participate or should participate in that experience. So while you're targeting children parents learn to in an environment that isn't condescending to them because it's for the benefit of their child. So I think that's a great way to overcome. This idea of well we don't want to talk over everybody's heads but at the same time we don't want to make it sound condescending to an audience. So this is a very large target audience something issues I think we need to target with education. Number one tear down the black box get people to understand what a nuclear reactor is it is my personal view that a nuclear reactor should be no more difficult to explain how it works than how a car. It's right. You have fuel called gasoline. I put it in the car. It goes in the engine that makes energy and that energy gets to take into the wheels and turns the wheels and that lets me drive my car. Wherever I want right. Same thing with a nuclear power plant. I've got fuel. It's called uranium. I can put it in this pressure vessel that makes energy that energy boils water which turns a turban which then turns a generator and makes electricity. So when I go home I can turn on my X. box and put in Wally and watch while the on my high definition T.V. It's that simple. You know kids kids can understand that everyone can understand that and it really should be more difficult than that to explain the second one and probably the biggest is to defeat the radiation bogeyman. This goes back to this whole idea of fearing the unknown fearing the unseen humans are woefully inadequate radiation detectors we can see four hundred but four hundred nanometers to seven hundred animators that's visible light. Right. That's the only radiation that our bodies really can detect and so it's no surprise that people fear this but the biggest things we need to do here is make sure that people understand what radiation is how we use it. The fact that not just nuclear power but all of the other ways that it's already benefited society and will continue to in the future. This is one of our biggest challenges and finally I would be a bad son if I didn't listen to my mother when she told me that there's no such thing as a free. This concept. Again not just for Nuclear Engineering and nuclear power. This is a light concept that I think goes understated in considering alternatives and options. The idea that there is some sort of a thing that will provide everything we want for free is just false. You really need to understand as a society. What the challenges are what the costs are for the benefits that we're going to accrue from a certain technology and it's my personal belief that the costs of nuclear are far outweighed by the benefits that it provides relative to all of these other choices that we have I'm not claiming any sort of groundbreaking idea here I think this is something that other people have recognized in fact this was a book recently released called nuclear power how a nuclear power plant works by a million from it's a great book that illustrates just how nuclear power plant works designed for children. So there's other people catching on to this there's work being made. I think we have a lot more waste a lot more work to do and ways to go but it is my assertion that education is not only important for the future of nuclear power but for the future of the global community at large. So that being said I'd like to thank everyone here and will get to talk a little bit later with the panel thank you thank you. Student loans was so I'm sensitive to your I'm also talk of persons here might get the visuals and that's true but the passages say things and proves it. So two areas of interest. First of all that you know there's really no safe or about how explain what I mean by that the second second mitigation of fire an explosion of facts that mocks the mixed oxide fuel fabrication facility using sand filters so I don't reactor safety is affected by decay heat can you turn off your car and walk away. Can you turn off your new can walk away. Well not really. If you're in your car if you have a if your if you lose a radiator hose in the car overheats you've got to stop get off the road right. Let it cool off to start the engine you stop burning gasoline. It begins a cool down because you're not putting more heat into the system a nuclear reactor. If it has a sustained loss of coolant once it has a loss of coolant it's essentially eighty a Batek you drop your control. Raji shut down the fissioning reactions but you still have the decay reactions going on from the K. products that are already been produced in the reactor and that's a significant energy source and sense that Sadia Batek There's no he transfer those conditions the reactor temperature necessarily goes up and that's a problem. So you can't just turn it off and walk away from you drop the control rods you can't walk away because it took a heat is going to continue to elevate the temperature of the reactor and bad things will happen. So the reactor safety is definitely affected by the. K. heat and it must be continuously removed at the reactor is shut down if it's not being removed that reactor temperature is going up failure to remove decay heat results in higher reactor temperatures because the system is essentially eighty Batek if you have a loss of coolant and higher temperatures may result in Serco new oxidation also in hydrogen production and hydrogen production comes out and fires and explosions. So let's think about it. We had Sure noble first of all we say what was a graphite reactor so is different. That's true it is different but it also has or can you manage it has or Connie and fires about Three Mile Island Three Mile Island had a reactor that overheated developed hydrogen bubble in the reactor and had explosion. Fortunately it did not rupture the reactor or the containment vessel certainly So the radiation was contained in Japan we had how many explosions at least four maybe five definitely four. One was a spent fuel storage pool I think it was from I think we all. Yes he was OK but it still had an explosion. So it overheated something overheated you produce hydrogen by the reaction with your calling him either with with well the reaction of obscene water in zirconium and you produce hydrogen had an explosion because once you have a combustible mixture of hydrogen and oxygen. If you're above the the detonation temperature is going to go. So this is a this is something that happens when I whenever we have a sustained loss of cooling. In a reactor. I think it's a significant safety issue and you know I don't have to continue to see reactors exploding over and over again to convince myself that there's a problem. You know it's happened enough with in my lifetime that it's clear there's a problem there. So I mean something needs to be changed. Now this is of a figure It was developed by origin print out by Benjamin at all as a study spent if you will heat up following laws of water during stories they're just looking at spent fuel. It's a Nuclear Regulatory Commission report was done in May of one thousand nine hundred seventy nine is what was published and what we have here on the origin it is a take a power divided by the operating power and down here below we have decay time and we say OK after ten days we were we're somewhere. Well we're not quite ten to the minus three but we're we're getting close attended the minus three which should be out here somewhere. Twenty or thirty days. So ten of the minus three is a tenth of a percent of the heat that's actually produced by the reactor when it's operating seems pretty small but if you're talking about a one gigawatt reactor a one point one gigawatt reactor. That's one point one megawatts of heat that has to be dumped which is a lot of heat and you've got to cool it to get out here over all the thousand days to get down to ten to the minus fifty which is still in a kilowatt range. So you can't just heat. You can't just run the reactor drop the control rods and and not maintain it. You've got to keep the cooling going to remove the decay heat for an extended period of time and the. This is true for spent fuel it's in the reactor is true for spent fuel it's in the storage pools and as we continue to store more and more spent fuel in the storage pools the risk of producing undesirable effects increases. So what is the issue Well the issue is the reactions or Kone I'm which is a metal that used in cladding to fuel it's a terrific metal because it has wonderful properties from the standpoint of the nuclear reactor. But from the standpoint of stability this it could. It's not the best choice. It's just not the best choice. Particularly when you look at this a fact that there were these are calling will react to water and as you elevate the temperature at some point it's going to begin to react. Now there's your call. You know also undergoes face transformation defamation bubbling Crystal defamation and destruction which destroys the physical properties of the cladding So the basic message is is that which we detailed in this report. I had here is a by Benjamin all the same report is that when you heat the spent fuel beyond the temperatures that was designed for he destroyed the physical properties of his or colony I'm. Eventually lead to oxidation of those are calling him which converts it into a powder and so what happens to the fuel policy end up in a little pile in the bottom of the reactor vessel and this is happened repeatedly It happened three mile island and it's happened at Japan I'm sure repeatedly. Now the actual temperature certainly by the time that you're up here around nine hundred resign a great juror well into. The range where you're going to have pretty significant oxidation reactions going on but according to this figure as low as around six hundred fifty degrees Centigrade you start to have problems where you have oxidation effects going on. They're looking at a lot of different cases. This is the maximum peak clad temperature as the ordinary sis's educate time again in this time in days and they looked at a lot of different cases because they were looking at spent fuel storage and they were looking at different configurations and you basically have radiation that you can use to remove heat and you have natural convection. So even if you don't have the force convection of the system is different. Designed to operate under you still can have natural convection radiation that will control the temperature to a certain extent but there is a problem. Israel obviousness figure in this was known since one nine hundred seventy nine. It's actually Nuclear Regulatory Commission report the work done at Sandia the N.R.C. even in two thousand and one in there in our in new regs seven hundred thirty eight is saying the results of the study any Kate that the risk of spent fuel pools is low and well within the commission's quarantine quantitative health objectives this risk is low because of the very low likelihood of his or causing a fire even though the consequences of his or cornea fire could be serious. I don't know where they get that because if you have if the reactor overheats you're going to have as a fire and you're kidding yourself to think otherwise they go on to say the probability is about one in a million per pool year. OK So that means to have five of them occurring at the same time assuming an independent events that's going to be one chance in ten to the thirty. OK So that's it doesn't something like that doesn't happen. Obviously the probabilities are wrong. That's actually the take home message here is the probabilities are wrong. The N.R.C. is being way too optimistic about the safety of the reactors because you're only talking if you go back and look here. What temperature the operator the reactors no number operate properly that what three hundred right three hundred degrees centigrade somewhere down here. If they get up another three hundred fifty degrees. They're in the danger zone for sure. As far as a safe operation is concerned and keeping the things under control. So the only issue is how fast it's going to heat up. So in my opinion reactor and spent fuel saving and spent fuel storage should be modified and the safety can be improved. I believe using the following steps. First of all eliminate combustibles or cornea Miss fuel cladding now the maybe some other zirconium compounds that would be more stable that could be used that would have acceptable properties from the standpoint of the new Tronics I don't know I know other people that are working on that trying to find alternatives or phoneme cladding I think it's a really key issue that needs to be looked at very carefully A second possibility is to build and operate smaller reactors and one of our earlier speakers was talking about that matching up with coal so that would be consistent here a smaller reactors or you have you have a smaller temperature rise of the smaller reactor reduce the fuel densities in the reactor cores and spent fuel storage pools because of the need for story space. We've gone the opposite direction in the spent fuel storage pools where we're increasing the density. Of the the class. Fuel rods and fuel assemblies in these storage pools that has a desirable effect as long as the pool is kept well cool. But if there's a loss of coolant acts in a sustained loss of coolant in a storage pool then what's going to happen is the temperature is going to go up drastically and we're going to have reactions of zirconium with oxygen and water production of hydrogen fires and explosions. So one way to counter that is to reduce the fuel densities in the reactor cores in the spent fuel storage pools and possibly by going to air cooling if you can get a nuff convective he transport and rate radiative heat transport to keep it cool enough but in the in the reactors looking and other possibilities look at providing more heat transfer by and by natural convection radiation. It's more difficult in the reactor vessel itself. And that's a major modification to the reactor design the way we have a right now five I think we should be designing to mitigate the consequences. The N.R.C. is saying it's only a one chance in a million this is going to happen. Well it's happened at least five times already that I'm aware of and probably more how many times does have to happen before we realize there is a significant issue. Just to say there's not a problem. I think really begs the question. So I think we should be designing to mitigate the consequences not just assuming that they're and they're not going to happen. We should be working to make the reactors fail safe which we're not doing now you might ask why. Why is that the the N.R.C. is not jumping on the bandwagon with this will remember. The N.R.C. has licensed all the reactors in North America. They've already said they're safe. So now if for them to go back and say that we can't use or Conan cladding means that they're going to have to admit that the reactors are not safe. The way they are right now they're not going to do that because in R.C. is a political institution it's not going to to to change what it's already said we say well gosh we haven't had a tsunami there's not a single army challenging this these reactors and so what's the problem there is a possibility that a mega tsunami could he hit the U.S. East Coast. Dr Simon de University College London is predicting the possibility of a two hundred foot high mega tsunami approaching the East Coast at five hundred miles per hour and where hits the shore washing as far as twenty miles inland say Whoa. And there are a lot of reactors along the East Coast here that would be at risk and possibly those in Texas and in Louisiana too because of the what if the tsunami wave ricochets off of Cuba and has north up into so many I you can imagine if this is something like this happens we won't just have one reactor. We'll have many reactors in trouble and it will be somewhat mind boggling his specific prediction is the next Maggot's tsunami may begin on one of the Canary Islands off the coast of North Africa where a wall of water or across the Atlantic to hit the U.S. East Coast the Caribbean and Brazil. Places guys at University College London he's talking about a part of an actual volcano the coombe or a. V B L. How do you mean via the well Kaino. On the island of law Palma in the Canaries is unstable and according to Dr de it could plunge into the plunge into the ocean during that all came as next eruption so pleasant thought there historically there have been volcanoes I mean there have been tsunamis actually larger than this. So this is not a something new. It's just something we haven't seen in recent times. And remember where you heard about it the next oxide plant. I think there are safety issues there too. I worked on that briefly in the review of that they had to chemical to senior chemical engineers working on the mixed oxide plant. Alex Murray who is still with the N.R.C. was working on it before I was they took him off and they put me on they didn't like be either because neither one of us was willing to say we thought what they were doing was a good thing. We both had similar problems. The idea I'm very enthusiastic about the idea. It kind of ties in with what cow was talking about earlier using up weapons grade plutonium to make a mixed oxide fuel and put it into reactors and burn it is a good way of getting rid of the Potomac problems with They've had this practical problems they've had a lot of delays cost overruns and now the utilities are not really interested they say in trying to use a new fuel in their reactors. So it's not sure where that project is going in the meantime the building a plant your tax dollars at work course a little bit of a cost overrun. But we won't worry about that right. We're only talking billions of dollars. We're not talking trillions. So it shouldn't be that much of an issue. And here's a picture of the plant is under construction is further along now. But the reviewers expressed concern because the N.R.C. is taking shortcuts on safety review to avoid construction delays and some of the questions that are not well answered in my opinion really chemical issues most of the dangers of chemical explosions and vapors. They have a rather interesting notion that they should only review the use of chemicals after they've been exposed to radioactive materials. So the cold chemical area where they have chemical storage going to be used in the plant is beyond the purview of the Nuclear Regulatory Commission which doesn't make any sense at all to me as an as a chemical engineer. Because when I come on a plant site I'm response as as a chemical engineer I'm responsible for every area that involves any kind of chemicals at all. Doesn't matter where the radioactive are or not. So I was not happy ventilation monitoring flow controls are lacking they they have and there's in their safety. Now as they say they're going to keep everything below fifty percent of the lower combustion limit but they never explain how they're going to do that. I don't explain how they're going to measure it either. So it's just kind of a promise but there's no indication how they're going to keep that promise no indication about ventilation monitoring flow controls regular nuclear retention by the filters is the standard way to go. My concern is that the there are a lot of different ways that they can run into trouble. Particularly with the chemistry that would lead to explosions and shock waves and what would happen with the heat of filters they would get blown out. How this happened Iraq Efe. Lats the government had a similar facility Rocky Flats in Colorado there and plutonium has been detected at Rocky Flats as far as five main five miles away from the plant and they had fires and explosions at Rocky Flats and they blew out heap of filters so my concern is that this is there be a similar problem that at the mock facility. They also have issues that I think were distressing about the lack of definition how they're going to suppose of certain ways for example they produce a solvent waste and I kept saying Well where is that where is that waste going to go and he said well it goes back to D.O.B. and once it goes to Dia we don't we're not concerned about it anymore. OK. When I was working at Oakridge we were working on fuel cycle issues working in action. I partitioning we're looking at the partitioning of actinides from all of the fuel cycle wastes not just the ones that are at a certain location and excluding the others you have to look at a comprehensive enter graded system and an R.C. is not requiring the applicant to even define. All of their waste disposal systems much less explain what's going to happen. But I finally found out for example that the solvent waste. The plan was to give it back to deal we in deal he was in going to ship this liquid solvent waste and I soon these plans are still in effect to Oakridge Where is be solidified in the solidified material be sent to the end of a test site so. The N.R.C. in my opinion is not doing a good job of looking at the overall picture on a comprehensive any greater basis. And they didn't even have adequate material energy bounces to describe the process which was another issue that the well I told my supervisor that if students in my design classes here at Georgia Tech had turned in resigned reports that show the same level of detail as far as material balances are concerned I would not give them a passing grade. They were exactly thrilled. But I'm sorry that's just the way it is chemical explosions may blow out heap of filters the red oil formation is an issue has been kind of slide over hydrogen methane formation is another possible path primarily from realises solvent radiologists can be an issue with and having adequate ventilation. They don't provide for continuous monitoring of her combustible gases and they have a new feedback loop taken in recent years. Suppose your combustible gas limit begins to elevate what are you going to do they have not provided any specific actions that they can take to to mitigate that circumstance. So looking at the MOX plan I think I think that the review should be expanded to provide any greatest say to review of all streams and ways I think they should provide for sand filters in addition of the heap of filters to ideal with a heap of filter blowout situation there are a lot of ways that you can lead to explosions in the mocks plant that could blow out heap of filters all of these can be dealt with in my opinion satisfactorily by protecting the HIPPA filters with sand filters where you set up a sand filter in series with a heap of filter you have then a shockwave that has to go through the sand filter first before it gets to the heap of filter and then attenuation the shock wave. So that when it gets through this. Sanjay alter the doesn't blow out the heap of filter sand filters would cover a myriad of sins. I think would be a single thing that they could do that would make the planet significantly safer but for whatever reason they have decided not to go that way and it seems most strange to me because historically Savannah River has had sand filters on all of their reprocessing facilities and they have had fires and explosions that say at Savannah River and the sand filters did their job and protected the HIPPA filter so they don't have to Tony Moeller the environment. In contrast to Rocky Flats to not have sand filters and does have did have a petroleum contamination problem with their neighbors. So the sand filters I think is a big thing. Eliminating a shipment of autonomy to me liquid waste on public highways I think is an outrage in R.C. says it's not it's not part of their problem because it's not they won't be leaving the plant it will be leaving from Indio east side and therefore it's not their problem which is utterly in my view begs the question I think they should be in our state should be not only licensing the MOX plant they should be licensing the disposal of all the wastes including the solvent waste and what I would like to know what kind of waste form is proposed or maybe an except for waste war may be perfectly fine but right now it's it's not being licensed and so N.R.C. is only looking at part of the picture. So I think this public should demand say for nukes eliminate combustibles or Kani. Design reactors for a fail safe shutdown designed reactors to mitigate the heat decay impacts and licensing a fuel cycle facilities such as much to consider the total says. Some of the disposition of all the waste and they should use sand filters in series with the help of filters to mitigate the effects of potential explosions and mocks which right now is not being planned this is a small change of course I was expected. Well I'm sure they will say they will cost billions of dollars to make that change. But again the be taking advantage of the taxpayer. So that's all my good news. I have for today. Thank you for your time and attention. Appreciate all those presentations that were quite informative. So we have time now that we can have some questions and answers so if you have any questions. He'd like to ask the panelists now's your time and the questions and I think you dollars for the people that they go to great rate that leave early and you'll just like yourself that ninety dollars or you're talking about the whole you're already talking about my story accidently You seem to be OK. The Because you're there you see there's the construction costs into the machine costs and this is then you'll see those costs new on that and you'll see that I don't normally like it and I fully funded the study five percent. Well this is going. We just both are going to also talk asked to meet with the pipes that are better ways and that's what attacking or. I mean you know you just need structured framework by for a way. You disclose all of that that this has to now. Cost you just very cost what you are certified it was then financing I mean it is then that cost is what utilities looking at or what we have to charge for the rate here to be in the rear deck and to be either best or is the best. So I'm using the cost of the deal we are still trying to get my head straight but as you know you need it seems like it's a broken system there's no evaluating that's off the cuff there's a news reader ladies in the job. It seems like there's a problem to her server right to the river to the river supposedly to bring us to here is this verse three hundred hundred federal government just bring in the Parliamentary Secretary for Jesus when the president says sure the other sectors which is the president when he made a call. That just getting I guess the most I feel like he and then there was a show trial and I love all we really are funny. There you go all the details like that in a bit but I see these are a living will almost all love part for the most but do these I was busy a bit more but he's part of the old lady he was the let's go wild card. I would bet a whole. You mean that really is that our little mole in here that I deleted it or they did go eat the child he's part of it you are bit but yes that was good for that Lovey the Gulf oil or all that he's getting is just part of using the oil. Let us go while there's a little bit more political issues to this where we go way back in your first news. How are we any Tom Tom can wish death a vote during the ninety's not nice here and we saw our policy there violent conflict of interest because you were responsible for promoting your power and bravely and so the hands of the time guaranteed mission us when we formed you better wages is one of the partners he was trying to target with our Morning nuclear energy along with a whole whole slew of technologies and the do the regulatory commission push for the regulation of the original operation new power plants nuclear fuels facilities earthing of your fuel cell in the United States. Now the Department of Energy retain a hand in the your own program so when when I was in the Navy we answer through the nation and to the partners. That's where we had our relations coming here we are so it is a political message all the time to do anything as we've all last occasion is not going to resign resign. Triac stopped all regulated by the partner's family and he heard this now she said the story you suddenly feel besides for you. For this family deal we went to the shapes to look it is all it's harmony with because you're selling fuel to Tilly's that's really energy so related issues with the department. You know we're a mess it is a mess for us we like about the expansion of nuclear power but it's probably for the US just I mean how do you build on this is that there is such a thing as what you say is the problems and you see yourself in the same side and I know I was in Bruno I would say that you saw the growing number getting nobody's community joy that I was you know we're going to grow as a country with that with our low low low low low low life is here with the public life. So this is a busy busy case. OK you know that was really you with that was part of it here but they're going to be such a good girl. You're either going to get your good Nuclear Waste Policy Act Federal Government is responsible for the disposal. You're going to hear is legally obligated kind of just goes like this when you're you know the utility responsible for their fuel is your own fuel up until point that for the government itself. Can you believe for once it is basically just. We're just supposed to feel that's where the three lie that the original number by the way was just to show you that that you know the SO is another big hot button issue of the field and again I know this or that it's not an issue it's a political issue. And there's a variety of things that play this is a really you know the great going by you figure see how that actually comes about how do you become an interstate you. There's a lot of things that they go into that decision making process so if you're interested. That would be what I think where you would love to see the historical viewpoint on you know you're going to go there. All your life. There are some ceramics I'm not really an expert on what the little one by my side has a different. This is higher temperature or someone here actually I feel pretty sure it's not a temperature that the client gets to that's what I'm trying to triac to do exactly that and that because indication rate is sufficiently low laugh about it that way you know that very small there's another report. And I don't want to know what the research. It was more like a very you know you're here I was here in town right through here this time I'm sure it's because we're this plays a role in terms of a job like this. And so what we have doesn't even want to go you know just to just say it hasn't happened yet. Therefore we are worried are we talking to myself the nobility that will. That's why you know what I'm saying is the problem really is on her where I was when I was up. My daughters were born where they were or you were I how you just went through all this and now it's just like you powerlessness when you test drive you suppose the red line is so easy you sites all these probabilities are good things like now bad things course probably because these are something out to you is a high risk. So I think what you're saying we're not aware of the problem because probability is my son. This is the way we should be saying why are we. Why have after you have her here in Michigan does something. Why have our why what is the series of steps where I was to ask what is miss the rights of the officer we don't have to worry about what's going to happen because it probably would have river levels this way. So here's here's the good man who made it is beyond signing basis and the facts six out where you do react and that's what you deserve the regime the day the operators were not able to initiate really any action until after all the explosions occurred. So we blew up three reactors and didn't kill a person. We're like well we blew out three reactors resulting in a way out of the minus five hundred my six probably didn't kill anybody being blocked off probability it works both ways you can get to lead. Now and then you can also do love to we didn't kill anybody result as an the operators were effectively we removed pictures because of the devastation and heard from the tsunami. So I honestly do not understand when you say that our ready to react to you when I say I sail with you when you're when you have a sustained loss of good reactors going to work. Yes you want to have some point you're going to have our stories are going my story for you are some are just more both yes and I'm happy you're going to hire a lawyer to do it you know with a lot of the high street lads who knew that the first book in this case we didn't. Mike Myers we was really slow and the result is we sprinted down if you crossed your history and closed a little which he counted plain wrong. Your people knew this was much more efficient than we are you supposed to lose the most hostile to true two wrongs don't make a right. Just because this town somewhere off the tongue resign damnation. It's not radiation our bodies have no distinguishing between British vision and relational Hirshman around British British it is all that I thought boy. If you look at the way this will get there. I guess by this is a definite he's there with the say so here I think also there is nothing there in the gap between the oversight of our last four cars where they lay for and why they get on that need it is what you believe will there be there you go. It was in his own car so you get the word love of life and your girl was doing was getting ever thought he would get a song to enjoy your life would be like you know you love our lead with it and we just end up staying for that other thing and in the end be there either. In other words or there are fears that it will leave us a while how why should that losing the heart of it. What are you know. Or why it was you or I love us the harder we really use it and that's all. Whether I think the letter with the. Measured in that will go for our little maker house to then he is the leader and you look at the small business now all this is all more visible a lot of is lot of it will reduce again but they did get as they all need that these sources a part of a few of them would be less Rather they would actually I saw it which is our goal for those jet car people. I saw your estimates for us but essentially as Westerners boy roll it may be ready. How's this very year two hundred out of this year. So you may need a longer view however you get a lot more people heal without any angst and that on a regular basis and it and it was good for you. It is here and yes in your chair that one in the years go on days with a vegetarian chili was a piece on that was not the lady of the day we're told it was a liver good question with leaving it science or losing at it. There are so many years out. It is something that people claim over the news easier exulting additional world are the answer or we won't do that and we need to go here and mind you there's a lot of people put it in and he needs and I think while if I did move I thought I just never so say that we should just say we don't want you to say the sound of the guns of a zero zero zero zero zero zero zero zero S. in his eyes. You did it to get our officer was there with his. What is more stable was that there was only did they know the laws because they already know we don't really know we'll leave getting is a bit. Do you really know that it was born here by the Pope it. Our belief or that he's not a particle our legally thought that he is either less powerful than the other they were more that he was in that life easily bendable they are both good. That's what I have to say there was a damn deal with the earthquake and Japan and then feeling killed the people we used I do all the time there's risks associated with Danny ha ha through thousands of cubic meters of water blah blah stored not enough using risk everything and do we have to understand what the consequences of our risks are the reaction that we take for what they were military was just you can't win in eight years. I get you over emphasize the risk of something more than what it is that will be kill you know get somebody off the issues and my wrists are. Well I would rather you receive all that I know this is an interesting topic and I think we have people that still want to discuss things but it is the time that we have allotted for the event. Imagine that the panelists may be open for questions afterwards or something like that but we want to thank everyone for coming especially want to thank our panelists you did a wonderful job pre-show your presentation.
