UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 MEMORANDUM TO:

SUMMARY

OF MEETING HELD ON FEBRUARY 12, 2024, WITH TRISO-X, LLC TO DISCUSS DRAFT REQUESTS FOR ADDITIONAL INFORMATION ON ENVIRONMENTAL PROTECTION (ENTERPRISE PROJECT IDENTIFIER L-2022-NEW-0005)

The U.S. Nuclear Regulatory Commission (NRC) staff hosted a virtual public observation meeting via Microsoft Teams with TRISO-X, LLC (TRISO-X) on February 12, 2024, from 3:00p.m. until 4:00p.m. The purpose of the meeting was to ensure mutual understanding of the NRCs draft requests for additional information (RAIs) regarding environmental protection in the TRISO-X license application (LA), as supplemented (Agencywide Documents Access and Management System (ADAMS) Accession No. ML23321A041). The TRISO-X LA was received April 5, 2022, (ML22101A200) and was supplemented by letters dated October 13, 2022, (ML22286A144) and November 4, 2022, (ML22308A251). The NRC staff discussed the draft RAIs with TRISO-X and provided additional context and clarifications regarding the RAIs.

The meeting continued the discussions from the previous meeting held on this set of RAIs on December 19, 2023 (ML23362A063) and focused on draft RAI-1 and RAI-4. TRISO-X presented slides during the meeting clarifying their understanding of the regulations and providing additional context to the previously submitted LA. The impacts of the intent to supplement the LA (ML24020A010) were also discussed, such as the addition of a third stack and timing of submissions. The NRC staff discussed concerns with the planned ambient air sampling locations and their coverage of nearby receptors and the methods to achieve continuous monitoring. TRISO-X further clarified that the unrestricted area boundary for gaseous air effluent is at the point of release (the stack) and the maximally exposed individual would be conservatively calculated at this point. The controlled area boundary is the site perimeter fence line. The NRC staff and TRISO-X agreed that bullet 2 of RAI-1 and bullet 4 of RAI-4 regarding stormwater or precipitation sampling locations were seeking the same information, and the response may be combined. Bullet 2 of RAI-4 regarding atmospheric CONTACT: Joseph Rudd, NMSS/DFM 301-415-5039 March 11, 2024 Signed by Rudd, Joseph on 03/11/24
