Email Summary of February 17, 2023 Call with TRISO-X to Discuss the Draft RAI Set 1 for Management Measures, Human Factors, and Structural for the License Application Date: Thursday, February 22, 2024 7:59:56 AM

On May 17, 2023, the U.S. Nuclear Regulatory Commission (NRC) staff held a call with TRISO-X, LLC staff (TRISO-X) to ensure mutual understanding of the first set of requests for additional information (RAI) (ML23127A011) to support the license application. The RAIs covered several high level methodology issues (programmatic issues) that needed to be resolved regarding human factors, management measures and structural. The Set 1 draft RAIs were provided to TRISO-X in advance of the meeting and contents were discussed during a call to ensure mutual understanding of the RAIs and give TRISO-X an opportunity to request any clarifications. The items discussed are listed below.

Management Measures:

RAI - 1 Provide information on the quality assurance for the construction phase.

RAI - 2 Provide the quality standards they plan to use for systems important to safety including IROFS and the program to maintain records.

RAI - 3 Identify basic components and how TRISO-X plans to apply quality assurance.

RAI - 4 Provide additional description of the TRISO-X plans to address the 18 quality assurance items identified in NUREG-1520, Chapter 11. They also need to clarify how they implement graded quality assurance.

RAI - 5 Describe how TRISO-X plans to control qualification of procedures and personnel.

Human Factors:

RAI - 1 Provide a human factors plan consistent with the guidance in NUREG-1520, Appendix E. Ensure that all nine elements identified in the guidance are addressed.

Structural:

RAI - 1 Provide the design requirements for natural phenomena events involving precipitation.

RAI - 2 No clarifications were needed for the draft RAI regarding flooding due to local intense precipitation.

Sincerely,

Matt Bartlett Sr. Project Manager NMSS/DFM/FFLB 301-415-7154
