Mr. George Wilson Vice President, Regulatory Affairs TerraPower, LLC 15800 Northup Way Bellevue, WA 98008
SUBJECT:
TERRAPOWER, LLC - FINAL SAFETY EVALUATION OF TOPICAL REPORT NATD-FQL-PLAN-0004, FUEL AND CONTROL ASSESSMBLY QUALIFICATION, REVISION 0 (EPID L-2023-TOP-0017)
Dear Mr. Wilson:
By letter dated January 25, 2023 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML23025A409), TerraPower, LLC (TerraPower) submitted a Topical Report (TR) entitled Fuel and Control Assembly Qualification, Revision 0, for the U.S. Nuclear Regulatory Commission (NRC) staffs review. By letter dated April 18, 2023, TerraPower submitted a supplement to the TR (ML23109A099). The TR identifies acceptance criteria for fuel qualification and presents select fuel qualification results in addition to ongoing and planned fuel qualification activities. The TR also summarizes a notional fuel surveillance plan for the collection of data to address certain targeted gaps and help develop new fuel designs. The TR was submitted in support of TerraPowers planned license application under Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Domestic Licensing of Production and Utilization Facilities. March 28, 2024 (ML24088A059) TerraPower submitted a construction permit (CP) on behalf of US SFR Owner, LLC (USO), a wholly owned subsidiary of TerraPower.
By email dated March 31, 2023, the NRC staff informed TerraPower that the TR provided sufficient information for the NRC staff to begin its detailed technical review (ML23086C087).
On June 7, 2023, the NRC staff transmitted an audit plan to TerraPower (ML23156A553), and subsequently conducted an audit of materials related to the TR from June 21, 2023, to October 5, 2023. The NRC staff issued a summary of the audit on February 6, 2024 (ML24043A155). On February 28, 2024, to support an Advisory Committee on Reactor Safeguards meeting, the NRC staff provided the unredacted version of the draft safety evaluation (SE) for the TR to TerraPower (ML23326A184).
The enclosed final SE is being provided to TerraPower because the NRC staff has found NATD-FQL-PLAN-0004, Revision 0, acceptable for referencing in licensing actions to the extent specified and under the limitations and conditions delineated in the SE. The final SE defines the basis for the NRC staffs acceptance of the TR.
The NRC staff requests that TerraPower publish an approved version of this TR within 3 months of receipt of this letter. The approved version should incorporate this letter and the enclosed SE after the title page. The approved version should include a -A (designating approved) following the TR identification.
