Sodium-cooled Fast Reactor (SFR) Risk and Safety Assessment White Paper - 2016

This paper, prepared jointly by Generation IV International Forum (GIF) Risk and Safety Working Group (RSWG) and the SFR Systems Steering Committees (SSCs), presents the status of the Integrated Safety Assessment Methodology (ISAM) for Sodium-cooled Fast Reactor (SFR) for further research and development. The intent is to demonstrate the adequacy of safety related design; to identify R&D needs to qualify safety related provisions, and to recommend directions for optimizing its risk and safety performance. The three main objectives of this work, identified during the first workshop which brought together SSC representatives and RSWG members, are: capturing in the short-term salient features of the design concepts that impact their safety performance; identifying crosscutting studies that assess safety design or operating features common to various GIF systems; and suggesting beneficial characteristics of the design of future nuclear power plants that should be addressed in subsequent GIF activities.
