SUBJECT:
FINAL SAFETY EVALUATION FOR WESTINGHOUSE ELECTRIC COMPANY TOPICAL REPORT WCAP-18850-P/NP, REVISION 0, ADAPTATION OF THE FULL SPECTRUM' LOCA (FSLOCA') EVALUATION METHODOLOGY TO PERFORM ANALYSIS OF CLADDING RUPTURE FOR HIGH BURNUP FUEL (EPID L-2024-NTR-0005)
Dear Mr. Ewing,
By letter dated February 29, 2024 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML24060A161), Westinghouse Electric Company (Westinghouse) submitted Topical Report (TR) WCAP-18850-P/NP, Revision 0, Adaptation of the FULL SPECTRUM' LOCA (FSLOCA') Evaluation Methodology to Perform Analysis of Cladding Rupture for High Burnup Fuel (Proprietary/Non-proprietary), for the U.S. Nuclear Regulatory Commission (NRC) review and approval.
Please find enclosed proprietary and non-proprietary versions of the NRC staffs final safety evaluations (SE) for TR WCAP-18850-P/NP, Revision 0, Adaptation of the FULL SPECTRUM' LOCA (FSLOCA') Evaluation Methodology to Perform Analysis of Cladding Rupture for High Burnup Fuel. The NRC staff has found the TR 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. When the TR 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 will be subject to a plants-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 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 within 20 business days of the receipt 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 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 Ekaterina Lenning via phone at 301-415-3151 or via email at Ekaterina.Lenning@nrc.gov.
Sincerely,
/RA/
