Abstract This project was a proof of concept of the use of the RAVEN software, a tool developed for the Risk Informed Safety Margin Characterization (RISMC) approach, with RELAP5-3D. This novel approach combines older probabilistic and mechanistic approaches to look at how and why the complex systems of a nuclear power plant might fail in an accident scenario in greater detail than the older approaches allow. This is done by combining the mechanistic outcomes of RELAP5-3D with random sampling of stochastic parameters to account for the probabilistic elements of an accident scenario. Proof of concept was provided by modeling Station Blackout scenarios for both a generic Mark 1 Boiling Water Reactor (BWR) and for the Multi-Application Small Light Water Reactor (MASLWR) design. The research shows that RAVEN and RELAP5-3D can be used to collectively generate a reasonable and realistic failure space for numerous stochastic parameters, and in doing so allows for greater examination of which safety systems might fail, how they fail, and what can be done to most effectively improve them. The intent is that these insights will be used to more effectively examine power plant accident scenarios and allow for more informed decision making with regards to power plant safety margins.
