DRAFT REQUEST FOR ADDITIONAL INFORMATION SUSQUEHANNA STEAM ELECTRIC STATION, UNITS 1 AND 2 LICENSE RENEWAL APPLICATION April 14, 2009 The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of PPL Susquehanna, LLC held a telephone conference call on April 14, 2009, 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 4.3.1-1 The Susquehanna Steam Electric Station (SSES) Fatigue Monitoring Program (FMP) relies on transient cycle monitoring to evaluate the fatigue usage described in the license renewal application. It is essential that all thermal and pressure activities are bounded by the design specifications and cycles of all significant thermal events are captured and logged. In the response to RAI B.3.1-1, dated August 01, 2008, it states that SSES FMP cycle counting assumes every event has a severity equal to that assumed in the design basis.
To ensure effectiveness and validity of the fatigue monitoring program, the staff requests additional information, as described below:
a) Confirm that all monitored transient events were bounded by the design specifications.
b) Specify the time (years) over which actual transient monitoring and cycle tracking activities took place. If there have been periods in which transients data are not recorded since the plant startup, for any types of transients, specify the affected time frame. For the time periods for which transients were not monitored, provide justification to demonstrate that the projected cycles for this unmonitored period are conservative.
Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.
D-RAI 4.3.1-2 LRA Section 4.3.1 states that Normal, upset, and test conditions used in the fatigue analyses of the Reactor Pressure Vessel (RPV) assembly are summarized in Table 4.3-1.
Design cumulative usage factors (CUFs) for the limiting RPV assembly locations are obtained from applicable design reports and are summarized in Table 4.3-2... LRA Tables 4.3-1 and 4.3-2 include 60-year cycle projections and 60-year CUF projections, respectively, for Units 1 and 2.
ENCLOSURE 2
a) LRA Table 4.3-1 shows that the 60-year projected cycles for a majority of transients are lower than the respective design cycles, approximately by a factor between 2 and 3 for both units. For startup and shutdown transients, the 60-year projected cycles are higher than the design cycles, by approximately 30%. LRA Table 4.3-2 shows that for some of the limiting RCPB locations, the 60-year projected CUF values are much lower than the 40-year design CUF values, up to a factor of 10 and even greater.
Describe the basis for the large reductions in CUF values with relatively minor reduction in cycle projections, in spite of some cases having projected higher cycles higher than the design cycles.
b) LRA Table 4.3-1 indicates that the ratios of the design cycles to the 60-year projected cycles are distinct for each transient. Describe how 60-year CUF projections were made.
Discussion: The applicant indicated that the question is clear. This D-RAI will be sent as a formal RAI.
D-RAI 4.3-9R In letter dated November 26, 2008, the applicant responded to RAI 4.3-9 by stating the following:
The dissolved oxygen levels in the SSES Unit 1 and Unit 2 feedwater systems, before and after the implementation of hydrogen water chemistry, are maintained at less than 50 parts per billion (ppb).
In addition, footnotes to the tables on page 4 and 5 of Enclosure 1 to PLA-6464 state that the environmental CUF values were determined assuming the following dissolved oxygen levels for the Feedwater system: 47 ppb with Normal Water Chemistry, 40 ppb with Hydrogen Water Chemistry for Unit 1; 40 ppb with Normal Water Chemistry and 39 ppb with Hydrogen Water Chemistry for Unit 2.
To facilitate its review and evaluation, the staff is requesting that the applicant:
a) Describe how the SSES reactor/turbine/condensate system is designed to maintain the oxygen level in the feedwater system less than 50 ppb.
b) Provide justification of why the data in Enclosure 1 to PLA-6464, entitled Dissolved Oxygen Data to Support Response to RAI 4.3-9, from 1994 to 1998 (before implementation of hydrogen water chemistry) is applicable for the entire operating period from startup through 1994 for the feedwater system.
c) Provide dissolved oxygen (DO) data for the SSES at full power for the three summer months of each of the following years: 1985, 1988 and 1991, for both Units 1 and 2. If the unit was not at full power during these periods, provide data from the next 3 month period that the unit was at full power.
d) Identify any periods where DO content in the feedwater system was greater than 50 ppb.
How were these periods consistently handled in the CUF calculations?
e) Provide the basis of sampling method, including the location(s) where water samples were taken, and confirm that the DO data in the feedwater system shown in PLA-6464 are bounding and applicable to all NUREG/CR-6260 locations for Fen calculations.
Discussion: The applicant indicated that the question is clear, however section b and d are pre decisional for PPL. The applicant stated, that at this time, SSES will not have answers to the question asked in b and d. This D-RAI will be sent as a formal RAI with the elimination of questions b and d.
