[1D02] Neutronic characteristics of coated particle thorium-fueled LWR
Keywords:coated particle fuel, Th, Pu, accident-tolerant fuel, BWR
We focused on the coated particle fuel as an accident-tolerant fuel for light water reactors. In this presentation, we propose a thorium fuel with high burnup in order to effectively utilize both Th produced when refining rare earths, and Pu owned by Japan.
Based on the specifications of the existing BWR in Japan, we created a fuel model in which the coated particles were dispersed and arranged in the SiC base material in the cladding tube. Multiple patterns with varying particle sizes and packing factors were prepared, and their burnup characteristics were evaluated using the Monte Carlo Codes for Neutron and Photon Transport Calculations (MVP). We also studied specific installation scenarios for domestic light water reactors.
