The U.S. Nuclear Regulatory Commission (NRC) staff conducted the meeting in accordance with NRC Management Directive 3.5, Attendance at NRC Staff-Sponsored Meetings (ML21180A271). The main points of discussion during the meeting included:
On February 23, 2023, the NRC staff held a closed meeting with TerraPower to discuss the Partial Flow Blockage Methodology for the Natrium design. Participants included representatives from TerraPower, General Electric Hitachi, Bechtel, and the Department of Energy. The enclosure provides the list of meeting attendees.
The NRC staff began the public meeting with introductions and explained that the meeting was closed due to proprietary information. During the meeting, TerraPower representatives discussed credible and non-credible types of blockages. TerraPower provided a partial flow blockage experimental data overview, Phenomena Identification and Ranking Table, and the partial flow blockage methodology evaluation model for the Natrium design.
TerraPower representatives and the NRC staff discussed the next steps for future interactions regarding the Natrium Reactor design.
