DRAFT REQUEST FOR ADDITIONAL INFORMATION SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 LICENSE RENEWAL APPLICATION October 8, 2008 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of PPL Susquehanna, LLC held a telephone conference call on October 8, 2008, to discuss and clarify the following draft request for additional information (D-RAI) concerning the Susquehanna Steam Electric Station (SSES), Units 1 and 2 license renewal application (LRA).

D-RAI 4.3-8 Section 4.3.2 of the LRA discusses the evaluation of the reactor pressure vessel (RPV) internals. The LRA indicates that structural evaluations were performed to address the effects of operation under extended power uprate conditions and the extended period of operation to 60 years. Explain how the number of reactor design transient cycles for 60 years of plant operation was determined for the analysis of the RPV internals.

Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.

D-RAI 4.3-9 Section 4.3.3 of the LRA discusses the evaluation of the effects of the reactor coolant environment on the fatigue life of components and piping. Table 4.3-3 provides the 60-year environmental cumulative usage factor (CUF) for each component evaluated. Provide a summary of the environmental factor (Fen) calculation for each component analyzed; including the values of oxygen level, temperature and strain rate used in the calculations. Also provide the basis for oxygen level, temperature and strain rate values used in the Fen calculations.

Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.

D-RAI 4.3-10 Table 4.3-2 of the LRA provides the 60-year CUF projections for the RPV shell at the shroud support for both units. List the transients that are the most significant contributors to the CUFs of both units. Discuss the fatigue analyses that were performed for the shroud support locations. Also include a discussion of any conservative assumptions that may have been used in the analyses.

Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.

ENCLOSURE 2

D-RAI 4.3-11 The August 1, 2008, response to RAI B.3.1-2 indicates the FatiguePro software is used for stress-based fatigue (SBF) monitoring of the feedwater nozzle forgings, feedwater nozzle safe ends, and the control rod drive penetrations. The response to RAI B.3.1-1 also indicates that the SBF monitoring methodology was benchmarked against the relevant design basis stress report for each component to ensure valid fatigue monitoring program fatigue results.

a. Describe the procedure used to benchmark the SBF monitoring locations against the relevant design reports. List the transients used for the benchmarking and indicate the design fatigue usage associated with each transient.

b. Discuss how the SSES SBF monitoring addresses the concern raised in proposed Regulatory Information Summary, Fatigue Analysis of Nuclear Power Plant Components, May 1, 2008 (73 FR 24094). Indicate whether any additional benchmarking of the SSES SBF monitoring is planned.

Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.
