March 26, 2019 Mr. W. Anthony Nowinowski, Executive Director PWR Owners Group, Program Management Office Westinghouse Electric Company 1000 Westinghouse Drive, Suite 380 Cranberry Township, PA 16066

SUBJECT:

ACCEPTANCE FOR REVIEW OF THE PRESSURIZED WATER REACTOR OWNERS GROUP TOPICAL REPORT PWROG-18034-P AND PWROG-18034-NP, REVISION 0, "UPDATES TO THE METHODOLOGY IN WCAP-15029-P-A, REV. 1, 'WESTINGHOUSE METHODOLOGY FOR EVALUATING THE ACCEPTABILITY OF BAFFLE-FORMER-BARREL BOLTING DISTRIBUTIONS UNDER FAULTED LOAD CONDITIONS"'PWROG-18034-P, REVISION 0, EVALUATION OF THE WCAP-10325-P-A WESTINGHOUSE LOCA MASS & ENERGY RELEASE METHODOLOGY

Dear Mr. Nowinowski:

By letter dated October 31, 2018 (Agencywide Documents Access and Management System Accession No. ML18067A228), the Pressurized Water Reactor Owners Group (PWROG) submitted Topical Report (TR), PWROG-18034-P and PWROG-18034-NP, Revision 0, "Updates to the Methodology in WCAP-15029-P-A, Rev. 1 and WCAP-15030-NP-A, Rev. 0, Westinghouse Methodology for Evaluating the Acceptability of Baffle-Former-Barrel Bolting Distributions Under Faulted Load Conditions" to the U.S. Nuclear Regulatory Commission (NRC) staff for review.

The NRC staff has found that the material presented is sufficient to begin our review. The NRC staff expects to issue its request for additional information by June 3, 2019, and issue its draft safety evaluation (SE) by August 23, 2019. This schedule information takes in consideration the NRCs current review priorities and available technical resources and may be subject to change.

If modifications to these dates are deemed necessary, we will provide appropriate updates to this information.

The NRC staff estimates that the review will require approximately 500 staff hours including project management time. The review schedule milestones and estimated review costs were discussed and agreed upon via email between Chad Holderbaum, Program Director, PWROG, and the NRC staff on March 14, 2019. Section 170.21 of Title 10 of the Code of Federal Regulations requires that TRs are subject to fees based on the full cost of the review.

As with all TRs, the SE will be reviewed by the NRCs Office of the General Counsel (OGC) to determine whether it falls within the scope of the Congressional Review Act (CRA). During the course of this review, OGC considers whether any endorsement or acceptance of a TR by the NRC amounts to a rule as defined in the CRA. If this initial review concludes that the SE, with its accompanying TR, may be a rule, the NRC will forward the package to the Office of

W. Nowinowski Management and Budget (OMB) for further review and consideration. Any review by OMB would impact the schedule for the issuance of the final SE.

If you have questions regarding this matter, please contact Jason Drake at (301) 415-8378.

Sincerely,

/RA/
