WESTINGHOUSE ELECTRIC COMPANYS FINAL TOPICAL REPORT SAFETY EVALUATION FOR WCAP-16943, ENHANCED GRAY ROD CLUSTER ASSEMBLY RODLET DESIGN

Dear Mr. Gresham:

The U.S. Nuclear Regulatory Commission (NRC) staff prepared a final Topical Report Safety Evaluation (TRSE) for WCAP-16943, Enhanced Gray Rod Cluster Assembly Rodlet Design, in support of the AP1000 post - licensing activities submitted by Westinghouse Electric Company (WEC).

The staff requests that WEC publish the applicable version(s) of the TRSE listed above within 1 month of receipt of this letter. The accepted version of the topical report shall incorporate this letter and the enclosed TRSE and add an -A (designated accepted) following the report identification number.

The staff has found that WCAP-16943 is acceptable for referencing in licensing applications for AP1000 designed pressurized water reactors to the extent specified and under the limitations delineated in the topical report and in the enclosed final TRSE. The final TRSE defines the basis for our acceptance of the topical report.

If the NRCs criteria or regulations change, so that its conclusion that the TRSE is acceptable is invalidated, WEC and/or the applicant referencing the TRSE will be expected to revise and resubmit its respective documentation, or submit justification for continued applicability of the TRSE without revision of the respective documentation.

Prior to placing the public version of this document in the public document room the staff requests that WEC perform a final review of the TRSE for proprietary or security-related information not previously identified. If you believe that any additional information meets the criteria, please identify such information line by line and define the basis pursuant to the criteria established in Title 10 of the Code of Federal Regulations Part 2, Section 390.

Document transmitted herewith contains sensitive unclassified information. When separated from the enclosure, this document is DECONTROLLED.
