CASL (the Consortium for Advanced Simulation of LWRs) is investing in the development of the multi-dimensional Bison fuel performance code for both transient and nominal performance analysis. The MPACT whole-core neutronics capability has been integrated with the Cobra-TF sub-channel solver to provide a neutron-transport based core-simulator with substantially improved fidelity over traditional diffusion-based core simulators. The Tiamat code is being developed to provide an integrated tool for predicting pellet-clad interaction and improving the high-fidelity core simulator.
