Enclosure to PLA-6464 Page 1 of 10 NRC RAI 4.3-8:
Section 4.3.2 of the license renewal application (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.
PPL Response:
LRA Section 4.3.2 identifies the fatigue evaluations performed to demonstrate the design adequacy of the RPV internals as a time-limited aging analysis (TLAA) requiring disposition under 10 CFR 54.21 (c)(1). In support of the extended power uprate (EPU) and license renewal (LR) projects for SSES, GE-Hitachi (GEH), under contract to PPL, performed the structural evaluation of the RPV internals to address the effects of operation under EPU conditions with extended operation to 60 years. The GEH evaluation concluded that the fatigue usage factors remain within the ASME Section III Subsection NG allowable limits. This evaluation was the basis for the disposition of this TLAA under 10 CFR 54.21(c)(1)(ii) in LRA Section 4.3.2.
As stated in the SSES FSAR Section 3.9.1.1.4, the fatigue analyses for the original 40-year life of the RPV internals considered the reactor design transients that are documented in the SSES FSAR Table 3.9-1. The structural evaluation of the RPV internals for EPU conditions did not alter the number of transient cycles that were considered for the original 40-year life. The EPU conditions were evaluated for any impact on the fatigue analyses of the internals, and new 40-year cumulative usage factors (CUFs) were determined for the EPU conditions. For extended operation to 60 years, the first step of the evaluation consisted of multiplying the new 40-year CUF for each component by a factor of 1.5. The resulting value for each component was considered to be a conservatively projected value for the 60-year CUF. If the 60-year CUF was less than 1.0, the evaluation was complete. If the 60-year CUF was not less than 1.0, additional evaluation was performed for the specific component. Ultimately, the GEH evaluation found that all RPV internals would have 60-year CUFs, under EPU conditions, of less than 1.0.
The projection methodology used by GEH increased the number of reactor design transient cycles for 60 years of plant operation by a factor of 1.5 over the original numbers of cycles defined in SSES FSAR Table 3.9-1.

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.
PPL Response:
Summaries of the environmental factor (Fen) calculations for each component analyzed for each SSES unit, including the values of oxygen level, temperature and strain rate used in the calculations, are provided in the tables below.
The temperature and strain rate values that were used in the Fen calculations were assumed to be the bounding values, as explained in the notes for each table below.
The dissolved oxygen levels that were used in the Fen calculations were based on the review of plant data. The specific time periods for which the plant data was reviewed to determine the typical levels used in the Fen calculations, which were performed in 2006, were not documented in the calculations. Thus, in response to this RAI, PPL sampled dissolved oxygen data from both SSES units, covering operation before and after the implementation of hydrogen water chemistry, to demonstrate that the levels assumed in the calculations are typical levels encountered during plant operation. The sampled data is presented in the Attachment. The data presented for time periods after 1999 is after the implementation of hydrogen water chemistry on both units.
The sampled data in the Attachment supports the following general conclusions, which support the values used for 0* in the Fen calculations. 0*, defined in NUREG/CR-6583 and NLJREG/CR-5704, is a parameter determined by the dissolved oxygen level.
" 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).
" Before the implementation of hydrogen water chemistry, the dissolved oxygen levels in the SSES Unit 1 and Unit 2 reactor coolant systems were greater than 200 ppb and less than 300 ppb.
- With hydrogen water chemistry in service, the dissolved oxygen levels in the SSES Unit 1 and Unit 2 reactor coolant systems, are less than 50 ppb.

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.
PPL Response:
The fatigue analyses for the shroud support were performed by the reactor vessel manufacturer, Chicago Bridge and Iron Company (CBI), under contract to the General Electric Company (GE). The analyses were performed and are documented in the reactor vessel stress report as a part of the reactor pressure vessel design. The analyses were performed in compliance with the requirements of ASME Section III, 1968 Edition to and including Summer 1970 Addenda, and paragraph NB-3338.2(d)(4) of the Winter 1971 Addenda, which supersedes paragraph 1-613(d) of the 1968 Edition.
The thermal transients applicable to the shroud support were specified by GE as a part of the SSES RPV design basis. The transients that were selected for detailed thermal analysis, on the basis of being the most severe, are 1) Natural Circulation Startup,
- 2) Pre-Op Blowdown, 3) Shutdown, and 4) Loss of AC Power. All other transients affecting the shroud support were grouped under the most severe of these four bounding transients, as the temperature gradients of the four evaluated transients were considered to bound those of all other applicable transients. Therefore, the analyses of these four transients yielded the most severe thermal stresses for the shroud support.
The stress analysis for the shroud support evaluated 40 locations in the shroud support area of the vessel, chosen on the basis of having the most severe stresses. The primary and primary plus secondary stress categories were evaluated in accordance with the ASME Code,Section III, Articles N-414.1, N-414.2, N-414.3, and N-414.4.
The fatigue analysis for the shroud support was performed in accordance with the ASME Code,Section III, Article N-414.5, for peak stress intensity. The ability of the vessel to withstand cyclic operation without fatigue failure is based on the largest magnitude of stress intensity and the largest stress concentration factor at any point of the stress model.
For the low alloy steel portion of the shroud support, the maximum stress amplitude (Sa) value was determined to be 72.53 ksi, and the corresponding allowable number of cycles is 1500, per the ASME Section III fatigue curve, Figure N-415(A). For the inconel portion of the shroud support, the maximum Sa value was determined to be 81.20 ksi, and the corresponding allowable number of cycles is 2800, per the ASME Section III fatigue curve, Figure N-415(B).
Enclosure to PLA-6464 Page 6 of 10 All of the design transients, along with the associated number of cycles assumed in the 40-year life, considered to have an impact on fatigue are as follows:
Design Hydrotest 130 cycles Startup and Shutdown 111 cycles Turbine Trip 10 cycles Partial Feedwater Heater Bypass 70 cycles Turbine Generator Trip 40 cycles All Other Scrams 140 cycles Pre-Op Blowdown 10 cycles Loss of AC Power 15 cycles Design Seismic 10 cycles Total Cycles: 536 Since the analysis conservatively assumed all transients would have the maximum Sa value, the maximum fatigue usage was conservatively determined as the total number of design transient cycles (536) divided by the allowable number of cycles determined for the maximum Sa value. Therefore, for the low alloy steel portion of the shroud support, the maximum fatigue usage is 536/1500, or 0.358. For the inconel portion, the maximum fatigue usage is 536/2800, or 0.191. The limiting value for the low alloy steel, which is applicable to both SSES units, was reported in Table 4.3-2 of the SSES LRA under the "Design CUF" column.
The "60-Year CUF Projections" for Unit 1 and Unit 2 are 0.312 and 0.297, respectively, as shown in Table 4.3-2 of the LRA. The actual plant cycle counts from the beginning and end of a ten-year period of plant operation were used to determine the fatigue usage at those same points in time, using the methodology used in the RPV stress report, as described above. Then, a representative rate of fatigue usage accumulation was determined and used to project the fatigue usage at 60 years, with some conservative adjustments to account for the power uprates implemented at both SSES units.
For Unit 1, the 60-year fatigue usage projection was calculated as follows:
U 60 = U 200 2 + [(U 20 02 - U 1992 ) / Time 199 2 to 2002 ]
- Time 2 002 to 2042
- FEPU where: U 60 = the projected fatigue usage for 60 years of operation.
U 199 2 = the fatigue usage experienced as of 04/26/1992, which is the end of the 7 th operating cycle. The 7 th operating cycle represents the nearest outage that allows 10 years of plant operation to be considered for the forward projections. This value is calculated as the total number of analyzed
Enclosure to PLA-6464 Page 7 of 10 design transients that occurred as of 4/26/1992 divided by 1297.*

= the fatigue.usage experienced as of 12/31/2002, which is the latest fatigue usage information. This value is calculated as the total number of analyzed design transients that occurred as of 12/31/1992 divided by 1297.*
Time1 992 to 2002 = elapsed number of days from 1992 cycle counts (04/26/1992) to the date of the most recent fatigue usage (12/31/2002).
Time 2002 to 2042 = elapsed number of days from most recent fatigue usage (12/31/2002) to the end of 60-year operating period (07/17/2042).
FEPU = 20% Extended Power Uprate (EPU) factor =
1.20. It was conservatively assumed that EPU implementation occurred at the end of the last baselining period (12/31/2002).
- The design allowable number of cycles was reduced from 1500 to 1297 to conservatively account for the effects of the 5% power uprate implemented in 1995.
A similar calculation was performed for SSES-2 using unit-specific dates and cycle counts.
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 all the transients used for the benchmarking and indicate the design fatigue usage associated with each transient. Also, provide side-by-side comparison on stresses for each transient and each component used for the benchmarking.
Enclosure to PLA-6464 Page 8 of 10
- b. Discuss how the SSES SBF monitoring addresses the concern raised in proposed Regulatory Information Summary (RIS), "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.
PPL Response:
Part a:
The SSES SBF locations in the FatiguePro software were benchmarked against the relevant design basis stress reports by evaluating the key transient pairings from the design basis stress reports using the FatiguePro SBF analysis, and comparing the resulting alternating stress intensities and fatigue usage from FatiguePro to the values determined in the design basis stress reports. Adjustments were made to the Green's Functions, where necessary, to calibrate the FatiguePro analytical models so that the results from the governing stress reports were closely matched for these key transient pairings. The adjustments included scaling the Green's Functions such that the peak stress intensity output from FatiguePro was equal to or higher than the peak stress intensity from the design basis stress report. Any differences were evaluated by an independent calculation to determine acceptability. Discussions of the benchmarking results are provided below for each of the three SBF monitored locations at SSES:
Feedwater Nozzle Safe End Location:
From the design basis stress report for normal/upset conditions, the critical transient pair is Turbine Roll-Hot Standby. The alternating stress intensity for this load pair was determined to be 124.95 ksi in the design basis stress report. The FatiguePro simulation of this transient pair yielded an alternating stress intensity of 125.2 ksi. Since the same ASME Code fatigue curves were used in FatiguePro as in the design basis stress report, the FatiguePro fatigue usage is slightly higher than the design basis stress report due to the slightly higher alternating stress intensity.
A similar stress comparison was performed for the Partial Feedwater Heater Bypass transient. The design basis stress report estimated the thermal stress intensity range as 60.8 ksi, and FatiguePro estimated this range to be 60.13 ksi. Although the FatiguePro result is 1% lower than the stress report result, this difference is considered to be within the acceptable accuracy of the analytical models.
Feedwater Nozzle Forging Location:
Since the feedwater nozzle forging is a part of the feedwater nozzle and the thermal stresses in the nozzle forging are significantly lower than in the safe end, the benchmarking of the safe end was considered to bound the nozzle forging location.
Enclosure to PLA-6464 Page 9 of 10 CRD Penetration Location:
From the design basis stress report for normal/upset conditions, the critical transient pair is Natural Circulation Startup-Loss of AC Power. The alternating stress intensity for this load pair was determined to be 177.8 ksi in the design basis stress report, which includes a stress concentration factor of 4.0 for the presence of a weld. The FatiguePro simulation of this transient pair yielded an alternating stress intensity of 166 ksi. The difference in stress was attributed to a conservative hypothetical temperature of 5347F used for the bottom head region in the design basis stress report, versus a temperature of 5220 F predicted in the bottom head region by FatiguePro. The temperature value estimated by FatiguePro matches the temperature value from the SSES reactor vessel thermal cycle design drawing, and was therefore considered valid, and the lower stress determined by FatiguePro was therefore justified. The incremental fatigue usage for one cycle of this transient pairing was computed as 1/3400 = 0.00029 in the design basis stress report, whereas FatiguePro computed a value of 0.000238. The FatiguePro fatigue usage was lower as a result of the lower alternating stress intensity resulting from the lower bottom head region temperature.
For emergency/faulted conditions, the critical transient pair is Improper Startup-Pipe Rupture. The alternating stress intensity for this load pair was determined to be 282.7 ksi in the design basis stress report, which includes a stress concentration factor of 4.0 for the presence of a weld. The FatiguePro simulation of this transient pair yielded an alternating stress intensity of 285 ksi. The incremental fatigue usage for one cycle of this transient pairing was computed as 1/27 = 0.037 in the design basis stress report, whereas FatiguePro computed a value of 0.0276. The difference in fatigue usage was attributed to a conservatively bounding value of KI, the multiplier for the maximum stress amplitude (Sa) that is required when the alternating stress intensity is greater than three times the design stress intensity (Sm). A Ke value of 3.33 was used in the design basis stress report based on the reactor design temperature of 575°F, versus a Ke value of 2.95 computed by FatiguePro using the maximum transient temperature of 550'F.
Part b:
At issue in the subject RIS is the conservatism of FatiguePro when a single'stress term Green's Function is used. Single stress term Green's Functions are used routinely in FatiguePro, as that is required by the methodology used by the software. As discussed in the response to Part a above, the SSES FatiguePro SBF component models were calibrated so that the key fatigue results (i.e., alternating stress intensity and fatigue usage) matched the results documented in the governing design basis stress reports, which were certified in accordance with ASME Code,Section III methodology.
Therefore, any approximations or potential non-conservatisms that may have been invoked in FatiguePro through the deployment of a single stress term Green's Function were compensated for in the calibration process.
Enclosure to PLA-6464 Page 10 of 10 The FatiguePro calibration process was not performed for all possible transient pairing scenarios. As a result, it is not possible to demonstrate, without further evaluation, that the SSES FatiguePro application fully addresses all possible scenarios associated with the issues identified in the subject RIS. To address this uncertainty, PPL will either implement fatigue monitoring software that satisfactorily addresses all issues raised in the RIS, or perform a confirmatory ASME Code,Section III fatigue evaluation for the SBF-monitored locations to justify the existing FatiguePro methodology prior to entering the period of extended operation.

- Note that the Unit 2 Reactor Water DO values on 8/17, 8/25, and 8/26 (in bold) are > 200, indicating that hydrogen water chemistry (HWC) was out of service on these days. For this data sample, that is only 3 days out of the 3-month sample period when HWC was not in-service. This supports the assumption that HWC is in-service 90% of the time.

- Note that the Unit 1 Reactor Water DO values on 5/12, 5/21, and 6/16 (in bold) are > 50, indicating that hydrogen water chemistry (HWC) may have been out of service on these days. For this data sample, that is only 3 days out of the 5-month sample period when HWC was not in-service. This supports the assumption that HWC is in-service 90% of the time.
