Vassallo, Chief Operating Reactors Branch No. 2 Division of Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Re: Nine Mile Point Unit 1 Docket No. 50-220 DPR-63

Dear Mr. Vassallo:

On April 27, 1983 a meeting was held between Niagara Mohawk and members of your staff to discuss the status of our masonry wall review, provide information regarding previous staff questions, and clarify the design criteria for our re-analysis of the walls. Subsequently, additional information was requested by your staff as indicated by your meeting minutes dated May 13, 1983. The attached document, "Design Criteria for Re-Analysis of Safety-Related Masonry Walls, Nine Mile Point Unit 1", incorporates our response to these inquiries.

Very truly yours, NIAGARA MOHAWK POWER CORPORATION I

C. V. Mang Vice President Nuclear Engineering & Licensing CVM/PAM:bd Attach.
