ACCEPTANCE FOR REVIEW OF THE PRESSURIZED WATER REACTOR OWNERS GROUP TOPICAL REPORT PWROG-17034-P, REVISION 0, EVALUATION OF THE WCAP-10325-P-A WESTINGHOUSE LOCA MASS &

ENERGY RELEASE METHODOLOGY

Dear Mr. Nowinowski:

By letter dated March 29, 2018 (Agencywide Documents Access and Management System Accession No. ML18067A228), the Pressurized Water Reactor Owners Group (PWROG) submitted Topical Report (TR) PWROG-17034-P, Revision 0, Evaluation of the WCAP-10325-P-A Westinghouse LOCA [loss-of-coolant accident] Mass & Energy Release Methodology, 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 August 30, 2018, and issue its draft safety evaluation (SE) in November 30, 2018. 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 700 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 May 2, 2018. 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 Management and Budget (OMB) for further review and consideration. Any review by OMB would impact the schedule for the issuance of the final SE.

W. Nowinowski If you have questions regarding this matter, please contact Brian Benney at (301) 415-2767.

Sincerely,

/RA/
