For more than a decade we have been involved in physics and design analysis of possible nextstep
tokamak options, including first ITER, later FIRE and most recently a tokamak neutron source for a
near-term transmutation reactor for burning the transuranics in spent nuclear fuel. We have also recently
supported the National Transport Code Coordination activity under this grant. In recent years, much of
the effort has been devoted to defining the physics and performance characteristics required of a tokamak
fusion neutron source that could drive a sub-critical reactor for the transmutation of the transuranics in
spent nuclear fuel. This document provides a final report for the activity in each of these areas for the last
grant period.

We are developing a Fusion Transmutation of Waste Reactor (FTWR) concept—a sub-critical,
metal fuel, liquid metal cooled fast reactor driven by a tokamak DT fusion neutron source. An emphasis is
placed on using nuclear, separation/processing and fusion technologies that either exist or are at an
advanced state of development and on using plasma physics parameters that are supported by the existing
database.
We have previously discussed the general capabilities of DT tokamak neutron sources for driving
transmutation reactors [1] and developed a design concept for a FTWR [2] based on normal conducting
magnets. The concept has been further developed in papers dealing with nuclear design and safety [3] and
with the evaluation of the potential impact on radioactive waste management [4].
The purpose of this paper is to examine how the FTWR design concept would change if
superconducting magnets were used.

The nuclear design and safety analyses for the Fusion
Transmutation of Waste Reactor (FTWR) are described.
The advantages of sub-critical operation for nuclear
stability and safety are illustrated.
