Abstract
This thesis provides detailed, stylized neutronic steady-state benchmark problems and solutions based on the Oak Ridge National Laboratory (ORNL) preconceptual design of a fluoride-salt cooled Small modular Advanced High Temperature Reactor (SmAHTR). The SmAHTR preconceptual design details a small scale, transportable reactor of 19 prismatic assemblies which utilize tri-isotropic (TRISO) particles of Uranium Oxicarbide (UCO) in pin-type graphite compacts for fuel. This set of stylized benchmark problems addresses several outstanding design gaps while preserving the desired reactor characteristics (high heterogeneity, small-scale, thermal hydraulic performance) of the preconceptual design.
