Dear Mr. McKinney:

In reviewing your letter dated October 11, 2006, concerning the request to increase the maximum steady-state power level at the SSES 1 and 2 from 3489 megawatts thermal (MWt) to 3952 MWt, the Nuclear Regulatory Commission staff has determined that additional information contained in the enclosure to this letter is needed to complete its review. These questions were discussed with your staff during a teleconference on March 19, 2007. As agreed to by your staff, we request you respond by April 30, 2007.

If you have any questions, please contact me at 301-415-1030.

REQUEST FOR ADDITIONAL INFORMATION RELATING TO THE APPLICATION FOR EXTENDED POWER UPRATE (EPU)

SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 (SSES 1 AND 2)

PPL SUSQUEHANNA, LLC DOCKET NOS. 50-387 AND 50-388 The Nuclear Regulatory Commission (NRC) staff is reviewing the request from PPL Susquehanna, LLC (PPL, the licensee) to support the application of the EPU for SSES 1 and 2.

The NRC staff has determined that additional information requested below will be needed to complete its review. The following RAIs pertain to supplemental PPL submittal PLA-6163 dated March 14, 2007.

1. Regarding the section titled "Integrated Surveillance Program (ISP)" of the licensee's submittal which addresses the implementation of the Boiling Water Reactor Vessel and Internals Project (BWRVIP) ISP to meet the requirements of 10 CFR Part 50, Appendix H:

a. What is the projected fluence for the Susquehanna, Unit 1 120 degrees azimuth capsule at its scheduled withdrawal date (2012), taking into account EPU conditions?

b. Provide an evaluation of the acceptability of removing the Susquehanna, Unit 1 120 degrees azimuth capsule in 2012 based upon its updated projected fluence and intended purpose within the BWRVIP ISP. In particular, explain how removing the capsule in 2012 will result in data from the capsule adequately representing those facilities who are identified as relying on it in BWRVIP-78 and BWRVIP-86-A.

2. Regarding the section titled "Upper Shelf Energy (USE)" of the licensee's submittal which addresses the evaluation of reactor pressure vessel (RPV) USE values to demonstrate compliance with 10 CFR Part 50, Appendix G:

a. Provide a table which demonstrates how the end-of-license USE values (or USE drop values where initial USE values are not available) were calculated for all RPV beltline materials considering EPU conditions. Sufficient detail regarding input parameters should be provided to allow the NRC staff to independently verify the results.

b. Demonstrate how the requirements of 10 CFR Part 50, Appendix G are directly met, or met through application of the equivalent margins analysis of BWRVIP-74-A, for the limiting plate/forging and weld materials for each of the Susquehanna RPVs.
