September 23, 2008 Mr. Britt T. McKinney Sr. Vice President and Chief Nuclear Officer PPL Susquehanna, LLC 769 Salem Blvd., NUCSB3 Berwick, PA 18603-0467

SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2, LICENSE RENEWAL APPLICATION

Dear Mr. McKinney:

By letter dated September 13, 2006, PPL Susquehanna, LLC submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54 (10 CFR Part 54), to renew the operating licenses for Susquehanna Steam Electric Station, Units 1 and 2, for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.

Items in the enclosure were discussed with Duane Filchner, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-4029 or by e-mail at evelyn.gettys@nrc.gov.

Sincerely,

\RA\

Evelyn Gettys, Project Manager Projects Branch 1 Division of License Renewal Office of Nuclear Reactor Regulation Docket Nos. 50-387 and 50-388

ML082530102 OFFICE LA:DLR PM:RPB1:DLR BC:RER1 BC: RPB1:DLR NAME IKing EGettys RAuluck DPelton DATE 9/11/08 9/15/08 9/23/08 9/18/08 SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION B.2.12-Bolting Integrity RAI-B.2.12-5 In the Susquehanna Steam Electric Station (SSES) license renewal application, the applicant states that the B.2.12 Bolting Integrity Program is consistent with the bolting recommendations identified in generic aging lessons learned (GALL)Section XI.M18, with exceptions. The applicant takes an exception to the GALL Report parameters monitored or inspected program element in regards to loss of preload. The applicant states that loss of preload is not an aging effect requiring management since it does not reach the 700 oF threshold at which the thermal effects aging mechanism occurs. However, loss of preload is identified in the GALL Report to include not only thermal effects, but also gasket creep and self loosening as aging mechanisms.

The gasket creep and self loosening aging mechanisms are not discussed in the exception, and appears to imply that loss of preload due to gasket creep or self loosening are not accounted for at SSES.

a. Please provide the technical basis for why SSES does not account for loss of preload due to gasket creep or self loosening and why SSES does not have any aging management review line items which reflect this aging effect.

b. Please clarify the methods used to identify a loss of preload, or indication of loss of preload, and provide the technical basis for doing so.

c. Please clarify whether the management of loss of preload for external bolting is included in the scope of the Bolting Integrity Program.
