SUBJECT:

FINAL SAFETY EVALUATION FOR WESTINGHOUSE ELECTRIC COMPANY TOPICAL REPORT WCAP-16045-P-A, ADDENDUM 2, REVISION 0, AND WCAP-16045-NP-A, ADDENDUM 2, REVISION 0, "UPDATED NEXUS CROSS-SECTION METHODOLOGY" (EPID: L-2019-TOP-0026)

Dear Ms. Zozula:

By letter dated June 26, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML19179A091), Westinghouse Electric Company (Westinghouse) submitted to the U.S. Nuclear Regulatory Commission (NRC) a request for review and approval of Topical Report (TR) WCAP-16045-P-A, Addendum 2, Revision 0, and WCAP-16045-NP-A, Addendum 2, Revision 0, Updated NEXUS Cross-Section Methodology. By letter dated May 20, 2020, the NRC issued its draft safety evaluation (SE) for the TR WCAP-16045-P-A, Addendum 2, Revision 0, and WCAP-16045-NP-A, Addendum 2, Revision 0 (ADAMS Accession No. ML20121A306). By letter dated June 18, 2020 (ADAMS Accession No. ML20121A306), Westinghouse provided comments on the draft SE.

The enclosed final SE addresses the applicability of the TR WCAP-16045-P-A, Addendum 2, Revision 0, and WCAP-16045-NP-A, Addendum 2, Revision 0, Updated NEXUS Cross-Section Methodology.

The NRC staff has found that WCAP-16045-P-A, Addendum 2, Revision 0, and WCAP-16045-NP-A, Addendum 2, Revision 0, Updated NEXUS Cross-Section Methodology, is acceptable for referencing in licensing applications to the extent specified and under the limitations delineated in the TR and the enclosed SE.

According to the guidance provided on the NRC website, we request that Westinghouse publish accepted proprietary and non-proprietary versions of these TRs within three months timeframe.

OFFICIAL USE ONLYPROPRIETARY INFORMATION

OFFICIAL USE ONLYPROPRIETARY INFORMATION C. Zozula 2 As an alternative to including the RAI questions 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 RAI questions:

1. The RAI questions and RAI responses can be included as an Appendix to the accepted version.

2. The RAI questions 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 TRs. The table should reference the specific RAI questions and RAI responses which resulted in any changes, as shown in the accepted version of the TRs.

If future changes to the NRCs regulatory requirements affect the acceptability of this TR, Westinghouse will be expected to revise the TR appropriately or justify its continued applicability for subsequent referencing. Licensees referencing this TR would be expected to justify its continued applicability or evaluate their plant using the revised TR.

Sincerely,

/RA - Leslie Perkins for/
