Docket No. 50-348 V. S. Nuclear Regulatory Commission ATTN: Document Control Desk c

Washington, DC 20555 Joseph M. Farley Nuclear Plant - Unit 1 Radial Peakina Factor Limit Report Gentlemen:

Enclosed is the Radial Peaking Factor Limit Report for Cycle 12 of Unit 1.

This report is provided in accordance with Paragraph 6.9.1.11 of the Unit 1 Technical Specifications. Also enclosed is a copy of the elevation dependent peaking factor versus core height graph for Cycle 12 of Unit 1, which is being submitted in support of the subject report.

The enclosed Radial Peaking Factor Limit Report was evaluated using the Power Shape Sensitivity Model (PSSM) screening process to ensure that the cosine shape remains the limiting power distribution in the large break Loss of Coolant Accident (LOCA) analysis.

(Reference WCAP-12935, May 1991.) The PSSM process eliminates the need for the currently applied penalty factor on the Fxy(z) surveillance data.

If you have any questions,- please advise.

Respectfully submitted, N '.L ?"1 ~'\\
