Nuclear Heating of In-Core Components for CANFLEX Low-Void-Reactivity Fuel in Bruce B

Abstract

A nuclear heat balance showing the distribution of nuclear energy for a Bruce B reactor fuelled with CANFLEX Low Void Reactivity Fuel (LVRF) bundles has been assembled. The nuclear energy balance in the Bruce-B reactor components is obtained from balance tables that take into consideration the different aspects of nuclear heating: release (production), deposition and transfer. The distribution of nuclear energy 'inside the core and outside the core' generated in the fission process in the fuel is calculated with a different methodology for each region.
