Development of an Advanced Deterministic Reactor Physics Modeling Tool

76008-The design and development of next generation nuclear reactors will require accurate and efficient reactor physics simulation tools. More accurate simulation methods can both shorten product development time and lead to the development of reactor designs with improved efficiency, safety, and reliability. Conventional analysis tools employ approximations which limit their accuracy and effectiveness. This project will develop an intuitive, fast, and accurate reactor physics simulation tool that is compatible with established computer aided design (CAD) and computer aided engineering (CAE) practices. It is based on the application of a novel, deterministic solver that has been shown to provide a favorable combination of accuracy and speed for a broad range of simulations. Phase I will develop and verify a proof-of-concept reactor modeling process. Both steady-state and time-dependent simulations will be evaluated by comparison with tests conducted in an actual reactor. Commercial Applications and Other Benefits as described by the awardee: By reducing design uncertainties, the new simulation tool should improve the efficiency and performance of reactor development activities, leading to increased reactor safety and efficiency. The technology should be applicable to a broad range of reactor types, including commercial power, research, isotope production, and naval and space propulsion.
