MARMOT: Mesoscale Fuel Performance Code

MARMOT is a mesoscale fuel performance code. As such, it can predict the evolution of the microstructure and material properties of fuels and claddings due to stress, temperature, and irradiation damage. MARMOT can, therefore, supply microstructure-based materials models to other code that works on engineering scale, which is larger than mesoscale, with an example being BISON. MARMOT solves equations involving solid mechanics and heat conduction using the finite element method.
