Continuing Development of a Fuel Performance Model for the Canadian Supercritical Water Reactor Thorium Mixed Oxide Fuel

摘要

Fuel performance models are being produced for ThO_2-based ceramic fuel in support of the ongoing development of a design analysis tool for the Canadian SCWR. To date, the model has produced realistic results for (Th,U)O_2 fuel, based on a comparison with data from fuel irradiated at Chalk River Laboratories. Preliminary results for the (Th,Pu)O_2 model compared to irradiated fuel data, although is encouraging, indicate significant development is still required to predict (Th,Pu)O_2 behaviour.
