Dear Mr. Gresham:

By letter dated November 5, 2018 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18318A109), Westinghouse Electric Company (Westinghouse) submitted an approval (-A) version of topical report (TR) WCAP-17203-P/WCAP-17203-NP, Revision 0-2, Fast Transient and ATWS Methodology, to the U.S. Nuclear Regulatory Commission (NRC) staff. Westinghouse has done so in accordance with our request to publish an approval non-proprietary version of this TR, as detailed in the transmittal letter of the NRC staffs final safety evaluation (ADAMS Accession No. ML18204A031) for the WCAP-17203-P/WCAP-17203-NP, Revision 0-2, Fast Transient and ATWS Methodology.

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 versions are acceptable for referencing in licensing applications for nuclear power plants to the extent specified, and under the limitations delineated in the accepted versions of the TR.
