Modeling and simulation An INL team has developed a computational framework that can accelerate nuclear fuels experiments by years. The Multiphysics Object-Oriented Simulation Environment or MOOSE is a computer simulation framework that advances the process for predicting the behavior of complex systems. MOOSE makes it easier to create simulations for complex mathematical models such as BISON or MARMOT which enable study of fuel behavior at scales ranging from a grain to a full pin. This sort of work has illustrated for example how tiny defects in nuclear fuel pellets can amplify over time to impact safety or energy production. This work helps the nuclear energy industry refine its understanding of operating margins to maximize efficiency without impacting safety. Radiation cleanup INL researchers have developed a technology that can remove radioactive particles or toxic metals from contaminated building surfaces more quickly and cheaply than traditional methods. The approach uses a rigid foam alone or with a specialized clay to pull contamination off porous horizontal or inverted surfaces. The new approach minimizes cost waste volume and worker exposure. The RD 100 Award-winning technology has been commercially licensed as Rad-Release Chemical Decontamination Technology or simply Rad-Release. INL computational mathematician Derek Gaston led the INL Computational Frameworks Group that developed the revolutionary MOOSE simulation platform. INL performs a series of tests to verify that the system will perform as designed during the mission. The tests include vibrational testing to simulate rocket launch conditions magnetic testing to ensure the systems electrical field wont affect the rovers sensitive scientific equipment mass properties tests to determine the center of gravity which impacts thruster calculations for moving the rover and thermal vacuum testing to verify operation on a planets surface or in the cold vacuum of space. 21
