The national nuclear lab Exceptional expertise unique infrastructure nuclear materials and strategic partnerships converge at INL the nations nuclear energy laboratory. INLs world-class capabilities and integrated infrastructure support a science-based approach experimentation theory modeling and simulation and first-of-a-kind demonstration. This approach yields technically achievable economically competitive and environmentally sustainable options for the entire nuclear enterprise. TechnologyAdvancing Nuclear Energy Spawning simulation tools The MOOSE simulation platform developed at INL has inspired creation of a suite of codes used to advance the understanding of nuclear fuel performance. BISON is a thermo- mechanical code exploring fuel performance at the engineering scale. The MARMOT code models fuel changes occurring at the microscale due to radiation damage. MOOSE can couple BISON with MARMOT to improve predictions. 24 The MOOSE platform generates striking simulations as shown by MARMOT left by solving complex mathematical models. For example the BISON application above solves a set of equations describing nuclear fuel pin behavior inside working reactors.
