Advanced Reactor Systems and Safety

Advanced Reactor Systems and Safety

Our research supports the US Department of Energy, US Nuclear Regulatory Commission, and other federal agencies in conducting applied R&D related to developing advanced reactor concepts for small modular reactors, molten salt reactors (both fluid and solid fueled), and space power applications. Such support includes conducting systems analyses for nuclear hybrid energy systems, evaluating siting options for new nuclear capacity, performing reactor dynamic modeling to support early design choices, developing advanced instrumentation and control (I&C) systems; conducting engineering economics assessments of costs, and analyzing the safety implications of these new technologies and reactor designs including the use of probabilistic risk assessment tools.
