UNITED STATES NUCLEAR REGULATORY COMMISSION*
WASHINGTON, D.C. 20555--0001 July 31, 1996
SUBJECT:
CLOSEOUT FOR PUBLIC SERVICE ELECTRIC AND GAS COMPANY'S RESPONSE TO GENERIC LETTER 92-01, REVISION 1, SUPPLEMENT 1 FOR SALEM NUCLEAR GENERATING STATION, UNITS 1 AND 2 (TAC NO. M92725 AND M92726)
Dear Mr. Eliason:
On May 19, 1995, the NRC issued Generic Letter 92-01, Revision 1, Supplement 1 (GL 92-01, Rev. 1, Supp. I}, "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 Regulations (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, S~pp. 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. dat~
relevant to th~ determination of RPV integrity, or an explanation of why the existing data base 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 RG 1.99, 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 and (I} the results of any necessary revisions to the evaluations of RPV integrity in accordance with the requirements of 10 CFR 50.60, IO CFR 50.61, Appendices G,and H to IO CFR Part 50, and any potential impact on the LTOP and P-T limits in the technical ~pecifications, or (2) a certification that previously submitted evaluations remain valid.

Revised evaluations and certifications were to include consideration of Position 2.1 of RG 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.
The NRC staff has noted that Public Service Electric and Gas Company (PSE&G) submitted.the information requested in Reporting Item (1) on August 14, 1995, and requested in Reporting Items (2) - (4) on November 20, 1995.. Your response indicates that PSE&G 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 Salem, Units 1 and 2.
Since PSE&G has submitted the requested information and has indicated that the previously submitted evaluations remain valid, the staff considers the RPV integrity data for Salem, Units 1 and 2 to be complete at this time.
The staff therefore concludes that no additional information regarding the structural integrity of the RPV at Salem, Units 1 and 2 is available at this time, and that your efforts regarding GL 92-01,
- Rev. 1, Supp. 1 are complete. This completes all actions related to the referenced TAC Number.
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.
These 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 to your plant.
When you provide this information, the staff may open a plant-specific TAC No. for its review.
Thank you for your cooperation.
