10CFR 50.90 G

Boston Edison Pilgrim Nuclear Power station Rocky Hill Road Plymouth, Massachusetts 02360 March 27, 1997 E. T. Boulette, PhD BECo Ltr. #2.97. 034 senior Vice President - Nuclear U.S. Nuclear Regulatory Commission Attention: Document Control Desk Washington, DC 20555

Docket No. 50-293 License No. DPR-35 Supplement to Proposed Change to Pilgrim's Safety Limit Minimum Critical Power Ratio Technical Specification i

Reference:

Boston Edison letter 2.97.002 to the NRC, dated January 24,1997.

By the referenced letter, Boston Edison (BECo) proposed a change to Pilgrim's Technical j

Specification Safety Limit Minimum Critical Power Ratio (SLMCPR). The new SLMCPR results are from a General Electric analysis for Pilgrim's Cycle 12 reactor core.

We provide Attachment 1 to supplement our January 24,1997, SLMCPR submittal based on the March 13,1997, conversation between GE Nuclear Energy (Wilmington, North Carolina) and the NRC. Attachment 2 provides an amended Bases page, B2-2, with the change bar to the second paragraph shortened to reflect a March 24,1997, conversation between NRC and Boston Edison.

The supplement and amended page B2-2 do not change the SLMCPR value or the proposed Technical Specification change; hence, the " Safety Evaluation and Determination of No Significant Hazards Consideration" we provided in the January 24,1997, letter remains valid and unchanged.

This supplement contains material that GE considers General Electric Property information as described in 10 CFR 2.790(a)(4) and for which an affidavit was provided as Attachment 4 to BECo's January 24,1997, letter. It is requested that this information continue to be withheld from public disclosure under the aegis of the January 24,1997, affidavit. Proprietary text is denoted by brackets in the right-hand margins in this supplement.

Should you require further information on this issue, please contact P. M. Kahler at (508) 830-7939.
