MAMMOTH is a general reactor physics application based on the MOOSE framework that leverages existing applications to solve complex multi-physics problems. MAMMOTH currently links the MOOSE applications for radiation transport (Rattlesnake), thermal-fluids (RELAP-7), and fuel performance (BISON) into a single simulation framework. Initial development started in 2013. MAMMOTH includes all of the capabilities provided by the linked MOOSE applications with:
Steady state and time-dependent coupled neutronics, thermal-fluids, and fuel performance simulations,
Macro and micro depletion with CRAM,
SPH equivalence method,
Decay heat calculations.
MAMMOTH has been used in the analysis of the following reactors/experiments:
PWR (pressurized water reactor)
MHTGR-350 (modular high-temperature gas-cooled reactor)
Transient Test Reactor (TREAT)
Coupled fast/thermal Test Reactor
Neutron Radiography Facility (NRAD), TRIGA reactor.
Multiphysics fuel performance studies
