OFFICIAL USE ONLY - PROPRIETARY INFORMATION OFFICIAL USE ONLY - PROPRIETARY INFORMATION August 6, 2025 Mr. Jerrod Ewing Manager, Operating Plants Licensing Westinghouse Electric Company 1000 Westinghouse Drive, Building 1, Suite 165 Cranberry Township PA 16066
SUBJECT:
FINAL SAFETY EVALUATION FOR WESTINGHOUSE ELECTRIC COMPANY TOPICAL REPORT WCAP-18904-P/NP, REVISION 0, CRITICAL POWER EXPERIMENTS AND D6 CPR CORRELATION FOR TRITON11 FUEL (EPID: L-2023-TOP-0054)
Dear Mr. Ewing,
By letter dated November 3, 2023 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML23307A183), Westinghouse Electric Company (Westinghouse) submitted Topical Report (TR) WCAP-18904-P/NP, Revision 0, Critical Power Experiments and D6 CPR Correlation for TRITON11 Fuel, to the U.S. Nuclear Regulatory Commission (NRC) for review and approval. By the email dated December 20, 2024, the U.S. Nuclear Regulatory Commission (NRC) staff issued its draft safety evaluation (SE) (ADAMS Package Accession No. ML24278A173).
The NRC staff has found the TR WCAP-18904-P/NP, Revision 0, acceptable for referencing in licensing applications for nuclear power plants to the extent specified and under the limitations delineated in the TR and in the NRC final SE. The final SE defines the basis for our acceptance of the TR.
Our acceptance applies only to material provided in the subject TR. We do not intend to repeat our review of the accepted material described in the TR WCAP-18904-P/NP, Revision 0. When the TR WCAP-18904-P/NP, Revision 0, appears as a reference in license applications, our review will ensure that the material presented applies to the specific plant involved. License amendment requests that deviate from this TR WCAP-18904-P/NP, Revision 0, will be subject to a plant-specific review in accordance with applicable review standards.
NOTICE: Enclosure 2 to this letter contains Proprietary Information. Upon separation from Enclosure 2, this letter is DECONTROLLED.
OFFICIAL USE ONLY - PROPRIETARY INFORMATION J. Ewing OFFICIAL USE ONLY - PROPRIETARY INFORMATION In accordance with the guidance provided on the NRC website, we request that Westinghouse publish accepted versions of the proprietary and non-proprietary TR WCAP-18904-P/NP, Revision 0, within three months of receipt of the date of this letter. The accepted proprietary version shall incorporate this letter and the proprietary final SE (Enclosure 2), and the accepted non-proprietary version shall incorporate this letter and the non-proprietary final SE (Enclosure 1) after the title page. Also, the accepted versions must contain historical review information, including NRC requests for additional information (RAIs) and your responses after the title page. The accepted version shall include an -A (designating accepted) following the TR identification symbol.
As an alternative to including the RAIs and RAI responses behind the title page, if changes to the TRs were provided to the NRC staff to support the resolution of RAI responses, and the NRC staff reviewed and approved those changes as described in the RAI responses, there are two ways that the accepted version can capture the RAIs:
- 2. The RAIs and RAI responses can be captured in the form of a table (inserted after the final SE) which summarizes the changes as shown in the approved version of the TR. The table should reference the specific RAIs and RAI responses which resulted in any changes, as shown in the accepted version of the TR.
If future changes to the NRCs regulatory requirements affect the acceptability of this TR, Westinghouse will be expected to revise the TR WCAP-18904-P/NP, Revision 0, appropriately.
Licensees referencing this TR would be expected to justify its continued applicability or evaluate their plant using the revised TR.
If you have any questions, please contact the Project Manager for the review, Ekaterina Lenning at 301-415-3151 or via electronic mail at Ekaterina.Lenning@nrc.gov.
Sincerely, Jennivine K. Rankin, Acting Branch Chief Licensing Projects Branch Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No.: 99902038
