Subject:

McGuire Nuclear Station Docket Numbers 50-369 and -370 Catawba Nuclear Station Docket Numbers 50-413 and -414 Proprietary and Non-Proprietary Versions of Topical Report DPC-NE-2001 By letter dated October 15, 1990, the NRC Staff provided the Safety Evaluation Report (SER) for Duke Power Company's Topical Report DPC-NE-2001P, " Fuel Mechanical Reload Analysic Methodology for Mark-BW Fuel." Enclosed for your information and use are copics of the approved report in proprietary and non-proprietary versions.

These reports are designated DPC-NE-2001P-A and DPC-NE-2001-A, respectively.

The SER did raise a concern relative to the basis for the approval of the methods. The SER made references (page 2 of the SER, Sections 2.2, 2.3, and 2.5) to the similarity of the approved methods to previously-approved B&W methodology. More appropriately, those references should have been to previously-approved Duke methodology. As discussed between Mr. Tim Reed of NRC and Scott GeLehr of Duke's Regulatory Compliance group, this letter will serve to document the more appropriate references to Duke's own methods. Clarifications are listed in Attachment I.

If there are any questions, please call Scott Gewehr at (704) 373-7581.

Very truly yours, n.s. %L M. Tuckman O(h 6 S.
