Subject:
NRC Transmittal of the Final Safety Evaluation for PWROG-21001-P, Revision 0 Mr. Dewey Olinski, PE PWR Owners Group, Program Management Office Westinghouse Electric Company 1000 Westinghouse Drive, Suite 172 Cranberry Township, PA 16066
SUBJECT:
NRC Transmittal of the Final Safety Evaluation for Pressurized Water Reactor Owners Group (PWROG)
Topical Report (TR) PWROG-21001-P/NP, Revision 0, Hydrogen-Based Transient Cladding Strain Limit
Dear Mr. Olinski,
By letter dated July 28, 2022 (Agencywide Documents Access and Management System Accession No.
(ADAMS No.) ML22209A255), as supplemented by letter dated March 9, 2023, (ADAMS No. ML23074A056),
the Pressurized Water Reactor Owners Group (PWROG) submitted Topical Report (TR) PWROG-21001-P/NP, Revision 0, Hydrogen-Based Transient Cladding Strain Limit (ADAMS No. ML22209A257) for the U.S.
Nuclear Regulatory Commission (NRC) staff review and approval. By email dated July 11, 2022, the NRC staff issued its draft safety evaluation (SE) (ADAMS No. ML23193A786) for PWROG-21001-P.
The PWROG provided comments on the draft SE via Box.com on August 8, 2023. A copy of the final SE for TR PWROG-21001-P, Revision 0 has been placed on BOX.com and access has been granted for review.
The NRC staff concludes that the purpose of the TR is to establish a new, alternative fuel performance acceptance criterion for the transient cladding strain (TCS), which could be used as an alternative to the existing criterion contained in a nuclear plants current licensing basis and be applied in fuel performance methods to the extent specified and discussed in the SE. The final SE defines the basis of NRCs acceptance of the TR. NRCs acceptance applies only to information provided in the subject TR. In accordance with the guidance provided on the NRC website, NRC requests that PWROG publish an accepted version of the TR, within three months of receipt of the date of this email. The accepted version shall incorporate this email and the enclosed SE after the title page.
This email has been placed in ADAMS (ML23284A412) and has been declared as an Official Agency Record for public availability.
Please be informed that the accepted versions of this TR must contain historical review information, including NRC requests for additional information (RAI) questions and the associated responses. The accepted versions shall also include a -A (designating approved) following the TR identification symbol.
As an alternative to including the RAI questions and RAI responses behind the title page, if changes to the TR provided to the NRC staff to support the resolution of RAI responses, and if 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:
(1.) The RAI questions and responses can be included as an Appendix to the accepted version.
2 (2.) The RAI questions and responses can be captured in the form of a table (inserted after the final SE) which summarizes the changes as shown in the accepted version of the TR. The table should reference the specific RAI questions 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, PWROG 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 the Project Manager for the review, Leslie Fields, at 301-415-1186 or via electronic mail at leslie.fields@nrc.gov.
Sincerely, Leslie C. Fields, US NRC Senior Project Manager NRR/DORL leslie.fields@nrc.gov
