Researchers at the Idaho National Laboratory have demonstrated realistic full-core predictive modeling of a commercial nuclear reactor over multiple years of use. The simulation platform is named MOOSE (Multiphysics Object Oriented Simulation Environment).
MOOSE is designed to make modeling and simulation, traditionally a daunting task, much more accessible to a broad array of scientists, in a fraction of the time previously required. For more on MOOSE and its revolutionary applications in nuclear engineering, please see here and here.
In this simulation video, the MOOSE team tracks hundreds of properties of thousands of reactor components to predict detailed conditions and behavior of 40,000 fuel rods in the new Westinghouse AP1000 reactor, of which eight units are now under construction in the United States and China.
