Decenber 10, 1996 Mr. E. Thomas Boulette, Ph.D Senior Vice President - Nuclear Boston Edison Company Pilgrim Nuclear Power Station RFD #1 Rocky Hill Road Plymouth, MA 02360 SUtMECT: CLOSE0VT FOR BOSTON EDIS0N COMPANY RESPONSE TO GENERIC LETTER 92-01, REVISION 1, SUPPLEMENT 1 FOR THE PILGRIM NUCLEAR POWER STATION (TAC NO. M92716)
Dear Mr. Boulette:
On May 19, 1995, the NRC issued Generic Letter (GL) 92-01, Revision 1, Supplement 1 (GL 92-01, Rev.1, Supp.1), " Reactor Vessel Structural Integrity."
In GL 92-01, Rev. 1, Supp. 1, the NRC requested that nuclear licensees perform a review of their reactor pressure vessel structural integrity assessments in order "to identify, collect, and report any new data pertinent to [the] analysis of [the] structural integrity of their reactor pressure vessels (RPVs) and to assess the impact of that data on their RPV integrity analyses relative to the requirements of Section 50.60 of Title 10 of the Code of Federal Regulatfons (10 CFR 50.60), 10 CFR 50.61, Appendices G and H to 10 CFR Part 50 (which encompass pressurized thermal shock (PTS) and upper shelf energy (USE) evaluations), and any potential impact on low temperature overpressure (LTOP) limits or pressure-temperature (P-T) limits."
More specifically, in GL 92-01, Rev.1, Supp.1, the NRC requested that addressees provide the following information in their responses:
(1) a description of those actions taken or planned to locate all data relevant to the determination of RPV integrity, or an explanation of why the existing database is considered complete as previously submitted; (2) an assessment of any change in best-estimate chemistry based on consideration of all relevant data; (3) a determination of the need for the use of the ratio procedure in accordance with the established Position 2.1 of Regulatory Guide 1.99, i
'J Revision 2, for those licensees that use surveillance data to provide a basis for the RPV integrity evaluation; and (4) a written report providing any newly acquired data as specified above i
and (1) the results of any necessary revisions to the evaluations of RPV l
integrity in accordance with the requirements of 10 CFR 50.60, p
l 10 CFR 50.61, Appendices G and H to 10 CFR Part 50, and any potential I
impact of the LTOP and P-T limits in the technical specifications, or (2) a certification that previously submitted evaluations remain valid.

Revised evaluations and certifications were to include consideration of Position 2.1 of Regulatory Guide 1.99, Revision 2, as applicable, and any new data. The information in Reporting Item (1) was to be submitted within 90 days of the issuance of the GL. The information in Reporting Items (2) - (4) was to be submitted within 6 months of the issuance of the GL.
i The staff has noted that Boston Edison Company (BECo) submitted the j
information requested in Reporting Item (1) on August 16, 1995, and requested in Reporting Items (2) - (4) on November 17, 1995.
Your response indicates that BECo has performed some additional reviews of the pertinent Owners Group databases and has not found any additional data regarding the best-estimate chemistries for the RPV materials and-surveillance capsules at the Pilgrim l
Nuclear Power Station.
Since BEco has submitted the requested information and has indicated that the previously submitted evaluations remain valid, the staff considers the RPV integrity data for the Pilgrim Nuclear Power Station j
to be complete at this time. -The staff therefore concludes that,no additional i
information regarding the structural integrity of the RPV,at.the Pilgrim Nuclear Power Station is available at this time, and that your efforts i
regarding GL 92-01, Rev.1, Supp.1 are complete. This completes all actions i
related to the referenced TAC Humber.
The staff has also noted that you are' waiting for some of.the Owners Groups Reactor Vessel Working Groups to complete activities to' establish a_
comprehensive RPV information database. yThese assessments are' expected to be completed by the summer of 1997. We request that you provide.us with the results of the Owners Groups' programs relative tolyour' plant.' ' When you 1
