(2) Letter, Richard V. Guzman (NRC) to Britt T McKinney (PPL), "Requestfor Information (RAI) -

SusquehannaElectric Station, Units I and 2 (SSES 1 and 2) - Appendix J Leakage Testing (TAC Nos. MD6544 and MD6545,)" datedJanuary 10, 2008.

In accordance with the provisions of 10 CFR 50.90, PPL Susquehanna, LLC (PPL) requested in Reference 1 approval of amendments to the Susquehanna Steam Electric Station (SSES) Unit 1 and Unit 2 Operating Licenses (NPF-14 and NPF-22). The proposed amendments add a new license condition to the Unit 1 and the Unit 2 Operating Licenses. The proposed license conditions permit the Type B and Type C tests on the Primary Containment Leakage Rate Test Program to remain on their current testing frequency rather than require all the tests to be performed prior to implementing Constant Pressure Power Uprate (CPPU) at the pressure corresponding to CPPU conditions. The CPPU is currently scheduled to be implemented on Unit 1 in the spring of 2008 and on Unit 2 in the spring of 2009.

The purpose of this letter is to provide a response to the NRC Request for Additional Information (RAI) contained in Reference 2.

Document Control Desk PLA-6321 NRC QUESTION NO. 1:

Section 4 of Attachment 1 to PPL's letter dated August 14, 2007, includes a table summarizing the Units 1 and 2 Type B and C test results. It is stated that the local leak rate tests (LLRTs) performed during Unit 2, spring 2007 refueling outage were performed at the constant pressure power uprate (CPPU) elevated test pressure. Also, the last sentence of Section 4 "Technical Analysis" states: "Therefore, performing LLRTs on the remaining Unit 1 and 2 valves prior to implementation of CPPU is not necessary."

Please provide the following:

a. What percentage of the LLRTs for both Unit 1 and 2 have been completed?

b. Were the LLRTs for Unit 1 performed at the CPPU elevated test pressure (48.6 pounds per square inch gauge (psig)) or at 45 psig?

c. Please confirm that: (1) this amendment request does not affect the Appendix J, Option B test performance or schedule, and (2) all LLRTs will be performed at the CPPU test pressure (48.6 psig) as they come due based on the established test schedule in the leakage rate test program.

PPL RESPONSE:

1(a) For Unit 1, 18% of the LLRTs have been performed at the increased test pressure. Following the Unit 1, spring 2008 Refueling and Inspection Outage (RIO), a total of 37% of the LLRTs will have been performed at the increased test pressure.

For Unit 2, 94% of the LLRTs have been performed at the increased test pressure.

1(b) The 18% completed LLRTs were performed at the increased test pressure (48.6 psig). All LLRTs scheduled for the spring 2008 RIO and beyond will be performed at the increased test pressure.

1(c) (1) The Appendix J, Option B test performance or schedule will not be affected by this amendment.

(2) All remaining LLRT tests will be performed at the increased test pressure performed as they come due based on the established test schedule in the leakage rate test program.

Document Control Desk PLA-6321 NRC QUESTION NO. 2:

The description of the proposed license conditions 2.C.34 for Unit 1 and 2.C.18 for Unit 2 (included in Attachment 2 to PPL's letter dated August 14, 2007) refers to primary containment leakage rate program tests. The technical analysis in Section 4, Attachment 1 states: "The requested new license condition would allow primary containment local leak rate tests (LLRTs) required by Technical Specification 5.5.12 ..." Considering the above, the description of the proposed license condition in Attachment 2 and Attachment 1 is not consistent.

Please confirm that the proposed license conditions 2.C.34 for Unit 1 and 2.C. 18 for Unit 2 only include the primary containment local leak rate tests for containment isolation valves.

PPL RESPONSE:

The proposed License Conditions 2.C.34 for Unit 1 and 2.C.18 for Unit 2 only include all local "Type B and Type C" tests performed in accordance with the Primary Containment Leakage Rate Test Program.

There are no new regulatory commitments established by these RAI responses.

If you have any questions regarding this submittal, please contact Mr. C. T. Coddington at (610) 774-4019.

I declare under penalty of perjury that the foregoing is true and correct.
