Meeting Summary:
On August 17, 2023, the U.S. Nuclear Regulatory Commission (NRC) staff held an observation (open) public meeting with TerraPower to provide the NRC staff with an overview of the Severe Accident Mitigation Design Alternatives (SAMDAs) for the Natrium design. Participants included representatives from TerraPower, General Electric (GE) Hitachi, Bechtel, and members of the general public. The NRC staff conducted the meeting in accordance with NRC Management Directive 3.5, Attendance at NRC Staff-Sponsored Meetings (ML21180A271).
The NRC staff began with introductions, described the meeting intent, and stated that the meeting was an observation-type public meeting. TerraPower provided an overview of the Natrium design, including a discussion of the project goals, plant overview, and graphics explaining the design. TerraPower discussed its methodology for SAMDAs and noted that it does not intend to deviate from the methodology of NEI 05-01, Severe Accident Mitigation Alternatives (SAMA) Analysis, Revision A. The SAMDA process flow chart was presented and discussed, ending with an overview of the potential risk determination utilizing probabilistic risk assessment. Lastly, TerraPower described Natrium-specific considerations, including the Natrium definition of a severe accident, and integration of the design with the SAMDA process.
TerraPower representatives and the NRC staff discussed the next steps for future interactions regarding the Natrium reactor design. The NRC staff expects to review a draft of the environmental report, including an evaluation of SAMDAs, as part of a forthcoming preapplication readiness assessment.
No regulatory decisions were made during this meeting.
