REQUEST FOR ADDITIONAL INFORMATION AS SET 17 FOR THE INTEGRATED SAFETY ANALYSIS

SUMMARY

INFORMATION REGARDING THE TRISO-X, LLC LICENSE APPLICATION FOR A FUEL FABRICATION FACILITY (ENTERPRISE PROJECT IDENTIFICATION NUMBER L-2022-NEW-0005)

Dear Jennifer Wheeler:

The U.S. Nuclear Regulatory Commission (NRC) staff has developed subsequent requests for additional information (RAIs) as set 17 to support the review of the TRISO-X, LLC safety and safeguards license application. Your application for a new fuel fabrication facility located in Oak Ridge, TN was submitted via letter dated April 5, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession Number ML22101A200) and supplemented by letters dated October 13, 2022 (ML22286A144) and November 4, 2022 (ML22308A251) and revised license application submitted by letters dated December 30, 2024 (ML24365A254) and January 31, 2025 (ML25031A449).

Our review of your license application has identified the need for RAIs to support the review.

The additional information requested in the non-public enclosure to this letter should be provided by August 29, 30 days from the date the draft RAIs were emailed to you to confirm mutual understanding of issues.

Please let us know if you have an interest in holding a call to discuss the draft responses prior to formal submittal, consistent with NRC staff RAI process described in LIC-FM-3, Section 2.10.1(b) (ML22208A272). Extending the formal responses beyond the 30 days, the need for supplements, or a second round of RAIs may result in an extension of the proposed review schedule of May 2026 (ML23305A193).

In accordance with Title 10 of the Code of Federal Regulations, Section 2.390 of the NRCs Agency Rules of Practice and Procedure, a copy of this letter will be available electronically for public inspection in the NRC Public Document Room (PDR) or from the Publicly Available Records component of the NRCs ADAMS. The PDR is open by appointment only. You may submit your request to the PDR via e-mail at PDR.Resource@nrc.gov or call 1-800-397-4209 between 8:00 a.m. and 4:00 p.m. (EST), Monday through Friday, except Federal holidays. The NRCs ADAMS is accessible from the NRC website site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

The Enclosure transmitted herewith contains Security-Related Information. When separated from the Enclosure, this document is decontrolled.
