A proposed fuel type for improved accident performance in LWRs (Light Water Reactors) is the TRISO (Tristructural-Isotropic) particles embedded in a NITE (Nano Infiltrated Eutectic) silicon carbide matrix. The release of radioactivity into the coolant is dependent on the integrity of the silicon carbide layer of the TRISO particles and the NITE-SiC matrix. Currently BISON is one of the codes being used to simulate the thermo-mechanical behavior of this fuel type. BISON, a code under development by Idaho National Laboratory, is built on the Multi-physics Object Oriented Simulation Environment (MOOSE). MOOSE is a massively parallel, finite element computational system that uses a Jacobian-free, Newton-Krylov (JFNK) method to solve coupled systems or non-linear partial differential equations. Recent work has focused on simulation predictions for future irradiations in ATR (Advanced Test Reactor).
