Abstract
A conceptual design of an inherently safe nuclear power reactor - the Near Boiling (NB) Nuclear Reactor - has been recently developed in order to provide the Victoria Class Submarines with electrical power for life-maintenance, navigation and weaponry systems. This will allow some under-ice operations in the Canadian Arctic and therefore uphold and reinforce Canada's sovereignty. Designed to complement the diesel electric power generation and as a result, to extend the operational envelope of the submarines, the Near Boiling Reactor employs TRISO fuel particles containing UO{sub 2} enriched to 20 w/o in {sup 235}U and light water as moderator. The purpose of this research project is to investigate fuel enrichment distributions in the reactor core, in addition to advanced thorium-based fuels in order to optimize the flux distribution and burn-up control of the NB, and to prolong the life expectancy of the core by making it coincide with the submarine complete overhaul and docking period. In a first stage, a uniform distribution of ThO{sub 2} and UO{sub 2} at an optimized ratio and concentration will be modeled using WIMS-AECL and MCNP-5. The second phase will consist in modeling diverse seed-blanket arrangements, with use of thorium in the blanket and enriched
