Dear Mr. Nowinowski:
By letter dated June 29, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18184A519), Pressurized Water Reactor Owners Group (PWROG) submitted an approval (-A) version of Topical Report (TR) BAW-1543, Revision 4, Supplement 7-A, Supplement to the Master Integrated Reactor Vessel Surveillance Program, to the U.S. Nuclear Regulatory Commission (NRC) staff. PWROG has done so in accordance with our request to publish an approval version of this TR, as detailed in the transmittal letter of the NRC staffs final safety evaluation (ADAMS Accession No. ML18038A347) for the original TR.
The NRC staff has completed its review of the approval version of the TR. The NRC staff verified that Westinghouse has met the requirements and determined that the submitted -A version is acceptable for referencing in licensing applications for nuclear power plants to the extent specified, and under the limitations delineated in the accepted version of the TR.
