Verification and Geometry Optimization of a One Fluid Molten Salt Reactor (OFMSR) with Fixed Volume

Various OFMSR core configurations with fixed volume have been studied using MCNP6.2 and Serpent-2 codes. It was apparent that radial blanket configuration generally showed a better neutronic performance than axial blanket configuration. Radial-1 possesses the better of the two radial configurations, with strongest negative TCR, longer Λ, and highest BR. In spite of marginally larger fuel inventory than its axial counterpart, Radial-1 still has the shortest DT. To obtain more optimized neutronic performance with fixed fuel salt volume, OFMSR is better using radial blanket configuration. Therefore, Radial-1 configuration is deemed as the neutronically optimum design among the models simulated in this study, and will be used for future design optimization.
