Designing an efficient reactor core simulation strategy for the Canadian-SCWR

The Canadian-SCWR is a Generation IV energy system that is designed based on the following two considerations: excellence in safety and reliability and a very low likelihood and degree of reactor core damage. Because the SCWR is a nuclear system, its general behavior is controlled by reactor physics, which is used to predict the population of neutrons in the core with time as well as the changes in reactivity resulting from variation in the core properties. Here we propose to design an efficient simulation strategy for the Canadian-SCWR based on numerical simulation in reactor physics. This implies selecting reactor physics software that can model the core configuration, implementing new models in the software and in the simulation strategy to improve the precision of the analysis and optimize the reactivity control mechanism and shutdown systems for normal operation conditions or during accident scenarios.
