UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON> D.C. 205K'F0001 February 6,
1997
,Mr. Robert G.
Byram Senior Vice President-Nuclear Pennsylvania Power and Light Company 2 North Ninth Street Allentown, PA 18101
Dear Mr. Byram:
SUBJECT:
CLOSEOUT FOR PENNSYLVANIA POWER
& LIGHT COMPANY'S (PP&L)
RESPONSE
TO GENERIC LETTER 92-01, REVISION 1, SUPPLEMENT 1, FOR SUSQUEHANNA STEAM ELECTRIC STATION (SSES),
UNITS 1
AND 2 (TAC NOS.
M92739 AND M92740)
On May 19, 1995, the NRC issued Generic Letter 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 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 (R-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 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 Regulatory Guide 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 (1) the results of any necessary revisions to the evaluations of RPV integrity in accordance with the requi.rements of 10 CFR 50.60, 10 CFR 50.61, Appendices G and H to 10 CFR Part 50, and any potential impact of the LTOP and P-T limits in the technical specifications, or (2) a certification that previously submitted evaluations remain valid.

Byram February 6,
1997 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.
The staff has noted that PP&L submitted the information requested in Reporting Item (1) on August 18, 1995 and requested in Reporting Items (2) (4) on November 17, 1995.
Your response indicates that PPEL 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 SSES units.
Since PPSL has submitted the requested information and has indicated that the previously submitted evaluations remain valid, the staff considers the RPV integrity data for SSES 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 SSES 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 data base.
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'rograms relative to your plant.
When you provide this information, the staff may open a plant-specific TAC No. for its review.
Thank you fo'r your cooperation.
