Sawtooth Simulation, Inc. is a Veteran-owned small business incorporated in Idaho and registered with the Small Business Administration. At Sawtooth Simulation, we provide commercial design, safety analysis, and multiscale fuel performance modeling and simulation services for Light Water Reactors, Advanced Reactor Technologies, microreactors, and specialized reactor concepts, including NASA's Nuclear Thermal Propulsion and Nuclear Electric Propulsion variants for Space Nuclear Propulsion. Sawtooth Simulation leverages multiphysics, multiscale software tools from the Department of Energy Office of Nuclear Energy (DOE-NE) Nuclear Energy Advanced Modeling and Simulation (NEAMS) Program, university programs, and in-house developments. Sawtooth Simulation utilizes the NEAMS Multiphysics Object-Oriented Simulation Environment (MOOSE) HPC framework to tightly couple native MOOSE-based tools with external non-MOOSE physics tools. Sawtooth Simulation offers the commercial nuclear industry efficient, cost-effective, and advanced modeling and simulation services for low-uncertainty simulations of new nuclear reactor concepts, including normal and off-normal power excursions and operational limits. Sawtooth Simulation also seeks to support advanced fuel qualification by predicting high-burnup physical fuel states, optimizing experiments to improve data acquisition quality, minimizing the number of experiments, and accelerating the deployment of advanced fuel concepts. This predictive capability can provide operational confidence to lengthen the nuclear fuel cycle and uprate the existing Light Water Reactor fleet, significantly increasing commercial profitability.
