The copies of the TS Bases pages are provided for NRC information only. The changes to the affected TS Bases pages will be incorporated in accordance with the TS Bases Control Program. 2 of 9

3.0 Background. The NRC Safety Evaluation Report (SER) of Structural Integrity Associates Topical Report (TR) SIR-05-044, permits Boiling Water Reactor (BWR) licensees to relocate their pressure-temperature (P-T) curves from the facility Technical Specifications (TS) to a Pressure and Temperature Limits Report (PTLR) utilizing the guidance in Technical Specification Task Force (TSTF) Traveler No. 419-A and in accordance with Generic Letter 96-03 (References 1, 2, 3, and 4). The proposed "Pilgrim Pressure and Temperature Limits Report (PTLR)" is based on the methodology and template provided in the NRC approved document SIR-05-044-A. The Pilgrim PTLR includes operating limits related to Reactor Coolant System (RCS) pressure versus temperature limits during heatup, cooldown and hydrostatic/class 1 leak testing. The curves will allow system pressurization at lower temperatures thus saving critical path time and provide improved work environment conditions for the inspectors during leak testing inspections.

4. 0 Technical Analysis 4.1 Pilgrim Fluence and Adjusted Reference Temperature (ART) Calculations, and Revised P-T Curves NRC approved the use of the current 48 EFPY P-T Curves through the end of Operating Cycle 18 by Pilgrim License Amendment No. 227 (Reference 5), in order to execute a plan to resolve RAMA fluence calculation benchmarking issues and to use current NRC approved- methodology to calculate fluence values to the end of extended license (Reference 7).

Previously, new fluence calculations were performed using RAMA methodology, but could not be benchmarked to the results of Pilgrim surveillance capsule data removed during refueling outage (RFO)-4. The RFO-4 Pilgrim surveillance capsule data yielded a Calculated-to-Measured (C/M) ratio that was outside of the tolerance of Regulatory Guide (RG) 1.190. Pilgrim has been a participant in the NRC approved BWRVIP Integrated Surveillance Program as authorized by License Amendment No. 209 (Reference 6). As such, Pilgrim opted ýto use the Monticello Nuclear Power, Plant, a BWR/3 class plant, benchmarking evaluation to produce benchmarked Pilgrim-specific fluence and ART values, and revised P-T curves. EPRI contractor, TransWare has performed their activation / fluence evaluation for the Monticello nuclear power plant capsule removed during their 2008 refueling outage. As a part of the Monticello evaluation, RAMA-calculated activation predictions were compared to measurements for the 3000 ISP capsule flux wires that were irradiated for 23 cycles (28.2 EFPY). Activation comparisons were performed for four copper, four iron, and four nickel flux wires that resided at various axial elevations in the capsule. The Monticello average C/M result for all copper activation measurements is 0.89, for all iron activation measurements is 1.08, and for all nickel activation measurements is 1.13. The resulting average C/M for all measurements in the Monticello capsule is 1.03 +/- 11% (Ia). The comparison results are well within the RG 1.190 guidelines and confirm that the RAMA fluence methodology provides an unbiased estimate of the fluence in the Monticello capsule data. In addition, the results obtained from the Monticello capsule comparisons using the RAMA Fluence Methodology are consistent with the observed comparisons from other BWRs (including BWR/2s, BWR/4s, and BWR/6s). The results of the Monticello flux wire activation analyses indicate that the RAMA fluence methodology does not exhibit a statistically significant bias, -unlike the results of the Pilgrim activation analysis discussed in Reference 5. Thus, from a RAMA Fluence Methodology perspective, the bias observed for the Pilgrim BWR/3 plant for RFO-4 capsule remains unique within the BWRs and can not be explained and will not be used for fluence, ART, or revising Pilgrim P-T curves. 3 of 9

Entergy has determined that Monticello reactor pressure vessel fluence calculation for a BWR/3 provides an acceptable benchmark for Pilgrim fluence data to support revised P-T Curves for Pilgrim Operating Cycle 18 and beyond. This information was discussed with the NRC Staff on or about October 17, 2008. The NRC staff concurred with the Entergy approach to use Monticello fluence for benchmarking Pilgrim RAMA fluence calculations (as documented in NRC ADAMS Accession Number ML090370920) and to submit Pilgrim revised P-T curves for NRC approval. The Monticello reactor vessel fluence calculation provides an acceptable benchmarking for RAMA calculated Pilgrim fluence, ART, and revised P-T curves. Unbiased RAMA methodology calculated fluence and ART data are used to develop the revised P-T curves included in the proposed PTLR. Even though the TransWare calculations for Pilgrim were performed in December 2005, prior to the Monticello benchmarking which was completed in 2008, there have been no material changes in the RAMA Code and Methodology that impacted the results of fluence and ART calculations and revised P-T Curves. Therefore, the unbiased fluence and ART values included in TransWare Report No. ENT-FLU-001-R-001, Rev.0, provides predictable Pilgrim reactor vessel fluence values using RAMA methodology in support of the proposed license amendment (Reference 11). The Pilgrim fluence calculation results show the vessel would experience peak fluence for 54 EFPY of 1.14x10 18 n/cm 2 at weld 1-338A/C location and 1.28x10' 8 n/cm 2 at the lower intermediate shell location, respectively. The N2 nozzle peak fluence at 54 EFPY was calculated to be 2.81xl 017 n/cm 2. Structural Integrity Report No. PNPS-22Q-301, ARTNDT and ART Evaluation, Rev. 1, (Reference

12) provides Pilgrim Adjusted Reference Temperature Calculations for 24, 34, 44, and 54 EFPYs (Table 3, 4, 5, and 6). These Tables show limiting material (plates and welds) characteristics and fluence values calculated at 24, 34, 44, and 54 EFPYs of operation.

Fluence is projected based on actual operation through 20.7 EFPY (April 2005). Fluence at intermediate exposure is linearly interpolated between 20.7 and 54 EFPY. Structural Integrity Report Nos. PNPS-03Q-301, Rev. 2 (Reference 13), Development of Pressure Test (Curve A) and PNPS-03Q-302, Rev. 2 (Reference 14), Development of Heatup/Cooldown (Curves B and C) are based on the requirements of Appendix G to 10 CFR 50 and Appendix G to ASME Section XI and the methodology in NRC approved Structural Integrity Report, SIR-05-044-A. As presented in PNPS-03Q-301, Rev. 2, RPV beltline, bottom head, and feedwater nozzle/upper vessel regions are evaluated. These regions bound all other regions with respect to brittle fracture, including the N2 nozzles through 34 EFPY. In addition, limiting stresses for the bottom head (CRD penetration) region were selected from all applicable design basis transients in order to accommodate any potential inadvertent bottom head cooldown events. The proposed P-T curves for hydrostatic and leak tests, subcritical heatup and cooldown, and critical core operation, were generated with fuel in the vessel for 24, 34, 44, and 54 EFPY operations, however only the curves applicable up to 34 EFPY are included in the PTLR. Pilgrim estimated EFPY will be approximately 26.4 at the end of the current operating cycle (18). 4.2 Pilgrim Pressure and Temperature Limits Report (PTLR) NRC GL 96-03 (Reference 2) allows plants to relocate their pressure-temperature (P-T) curves and numerical values of other P-T limits (such as heatup/cooldown rates) from the plant Technical Specifications to a PTLR, which is a licensee-controlled document. As stated in GL 96-03, during the development of the improved Standard Technical Specifications (STS), a change was proposed to relocate the P-T limits currently contained in the plant Technical Specifications to a PTLR. As one of the improvements to the STS, the NRC staff agreed with 4 of 9

the industry that the curves may be relocated outside the plant Technical Specifications to a PTLR so that the licensee could maintain these limits efficiently. One of the prerequisites for having the PTLR option is that all of the methods used to develop the P-T curves and limits are NRC approved, -and that the associated Licensing Topical Report (LTR) for such approval is referenced in the plant Technical Specifications. Based on this prerequisite, the purpose of the Structural Integrity Associates Report is to provide BWRs with an NRC-approved LTR that can be referenced in plant Technical Specifications to establish BWR fracture mechanics methods for generating P-T curves /limits that allow BWR plants to adopt the PTLR option. The objective of the Structural Integrity Associates Report provides P-T curve methods that are generically approved by the NRC so that P-T curves can be documented in a PTLR. In order to implement the PTLR, the analytical methods used to develop the P-T limits must, be consistent with those previously reviewed and approved by the NRC and must be referenced in the Administrative Controls section of the plant Technical Specifications. The Structural Integrity Associates Report provides the methodology for developing reactor coolant system (RCS) pressure test, core not critical, and core critical P-T curves for BWRs. As discussed in the NRC Safety Evaluation Report (Section 2.1 of the Reference 1), 10 CFR Part 50, Appendix G, requires licensees to establish limits on the pressure and temperature of the Reactor Coolant Pressure Boundary (RCPB) in order to protect the RCPB against brittle failure (i.e., against brittle "fast-fracture'). These limits are defined by P-T limit curves for normal operations (including heatup and cooldown operations of the Reactor Coolant System (RCS), normal operation of the RCS with the reactor being in a critical condition, and transient operating conditions) and during pressure testing conditions (i.e., either in-service leak rate testing and/or hydrostatic testing conditions). As discussed in the NRC SER, which approves the BWROG LTR SIR-05-044-A (Reference 1), this LTR was prepared by Structural Integrity Associates and has three sections and two appendices. Section 1.0 describes the background and purpose for the LTR. Section 2.0 provides the fracture mechanics methodology and its basis for developing P-T limits. Section 3.0 provides a step-by-step procedure for calculating P-T 'limits. Appendix A provides guidance for evaluating surveillance data. Appendix B provides a template PTLR. Section 2.0 of the PTLR provides the fracture mechanics methodology and its basis for developing P-T limits. The NRC staff evaluation of this section is based on the criteria contained in Attachment 1 of GL 96-03. Attachment 1 of GL 96-03 contains seven technical criteria that the contents of proposed methodology should conform to if license amendments requesting PTLR's are to be approved by the NRC staff. The NRC staff's evaluations of the contents of the BWROG methodology against the seven criteria in Attachment 1 of GL 96-03 are provided in Section 3.1 of the SER. Section 3.0 of the PTLR provides a step-by-step procedure for calculating P-T limit curves. This section indicates that P-T limits may be developed for other RPV regions to provide additional operating flexibility. The Pilgrim P-T curves considered three regions of the vessel: beltline, bottom head, and non-beltline (including flange) regions. The Pilgrim Pressure and Temperature Limits Report (P.TLR) based on the methodology and template provided in SIR-05-044-A is being submitted for review and approval. The pressure and temperature curves utilize the methodology of SIR-05-044-A. The PTLR will be a licensee-controlled document, subject to Technical Specification 5.5.9. Based upon the foregoing presentation, Pilgrim PTLR complies with the NRC GL 96-03 and TSTF-419-A and is developed in accordance with the NRC approved methodology. 5 of 9

5.0 Regulatory Safety Analysis 5.1 No Significant Hazards Consideration Entergy has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment: as discussed below:

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No. The proposed change modifies Technical Specifications (TS) Section 1.0 ("Definitions"), Specification 3.6.A.2, and revises 5.0 ("Administrative Controls"), to include section 5.5.9 to include reference to the Pressure and Temperature Limits Report (PTLR). This change adopts the methodology of SIR-05-044-A, "Pressure-Temperature Limits Report Methodology for Boiling Water Reactors", dated April-2007 for preparation of the pressure and temperature curves, and incorporates the guidance of TSTF-419-A ("Revised PTLR Definition and References in ISTS 5.6.6, RCS PTLR"). In an NRC Safety Evaluation Report dated February 6, 2007, "the NRC staff has found that SIR-05-044 is acceptable for referencing in licensing applications for General Electric-designed boiling water reactors to the extent," specified and under, the limitations delineated in the TR and in the enclosed final SE". As part of this change, the Pilgrim Pressure and Temperature Limits Report (PTLR) based on the methodology and template provided in SIR-05-044-A is being supplied for review. The pressure and temperature curves utilize the methodology of SIR-05-044-A. The NRC has established requirements in Appendix G to 10 CFR 50 in order to protect the integrity of the reactor coolant pressure boundary (RCPB) in nuclear power plants. Additionally, the regulation in 10 CFR Part 50, Appendix H, provides the NRC staff's criteria for the design and implementation of RPV -material surveillance programs for operating light water reactors. Implementing this NRC approved methodology does not reduce the ability to protect the reactor coolant pressure boundary as specified in Appendix G, nor will this change increase the probability of malfunction of plant equipment, or the failure of plant structures, systems, or components. Incorporation of the new methodology for calculating P-T curves, and the relocation of the P-T curves from the TS to the PTLR provides an equivalent level of assurance that the RCPB is capable of performing its intended safety functions. Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No. The proposed change does not affect the assumed accident performance of the RCPB, nor any plant structure, system, or component previously evaluated. The proposed change does not involve the installation of new equipment, and installed equipment is not being operated in a new or different manner. The change in methodology ensures that the RCPB remains capable of performing its safety functions. No set points are being changed which would alter the dynamic response of plant equipment. Accordingly, no new failure modes are introduced which could introduce the possibility of a new or different kind of accident from any previously evaluated. 6 of 9

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No. The proposed change does not affect the function of the RCPB or its response during plant transients. There are no changes proposed which alter the set points at which protective actions are initiated, and there is no change to the operability requirements for equipment assumed to operate for accident mitigation. This change adopts the methodology of SIR-05-044-A, "Pressure-Temperature Limits Report Methodology for Boiling Water Reactors", dated April 2007 for preparation of the pressure and temperature curves. Therefore, the proposed change does not involve a significant reduction in a margin of.safety. This change adopts the methodology of SIR-05-044-A, "Pressure-Temperature Limits Report Methodology for Boiling Water Reactors", dated April 2007 for preparation of the pressure and temperature curves, and incorporates the guidance of TSTF-419-A ("Revise PTLR Definition and References in ISTS 5.6.6, RCS PTLR"). In an NRC Safety Evaluation Report dated February 6, 2007, the NRC staff has found that SIR-05-044 is acceptable for referencing in licensing applications for General Electric-desighed boiling water reactors". Based upon the above, Entergy concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of no significant hazards consideration is justified. 5.2 Applicable Regulatory Requirements I Criteria The NRC has established requirements in Appendix G of Part 50 to Title 10 of the Code of Federal Regulations, in order to protect the integrity of the reactor coolant pressure boundary (RCPB) in nuclear power plants. The regulation at 10 CFR Part 50, Appendix G requires that the P-T limits for an operating light-water nuclear reactor be at least as conservative as those that would be generated if the methods of Appendix G to Section Xl of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (ASME Code, Section XI, Appendix G) were used to generate the P-T limits. The regulation at 10 CFR Part 50, Appendix G, also requires that applicable surveillance data from reactor pressure vessel (RPV) material surveillance programs be incorporated into the calculations of plant-specific P-T limits, and that, the P-T limits for operating reactors be generated using a method that accounts for the effects of neutron irradiation on the material properties of the RPV, beltline materials. Table 1 to 10 CFR Part 50, Appendix G provides the NRC staffs criteria for meeting the P-T limit requirements of ASME Code, Section XI, Appendix G, as well as the minimum temperature requirements of the rule for bolting up .the vessel during normal and pressure testing operations. In addition, the NRC staff regulatory guidance related to P-T limit curves is found in Regulatory Guide (RG) 1.99, Revision 2, "Radiation Embrittlement of Reactor Vessel Materials", and Standard Review Plan Chapter 5.3.2, "Pressure-Temperature Limits and Pressurized Thermal Shock". The regulation at 10 CFR Part 50, Appendix H, provides the NRC staff's criteria for the design and implementation of RPV material surveillance programs for operating light water reactors. Pilgrim Nuclear Power Plant demonstrates its compliance with the 'Appendix H through participation in the BWRVIP Integrated Surveillance Program (ISP) (Reference 6). In March 2001, the NRC staff issued RG 1.190, "Calculation and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence". Fluence calculations are acceptable if they are done with approved methodologies or with methods which are shown to conform to the guidance in RG 1.190. 7 of 9

Section 182a of the Atomic Energy Act of 1954 requires applicants for nuclear power plant operating licenses to include TS as part of the license. The Commission's regulatory requirements related to the content of TS are set forth in 10 CFR 50.36. That regulation requires that the TS include items in five specific categories: (1) safety limits, limiting safety system settings and limiting control settings; (2) limiting conditions for operation (LCOs); (3) surveillance requirements (SRs); (4) design features; and (5) administrative controls. The regulation at 10 CFR 50.36(d)(2)(ii) requires that LCOs be established for the P-T limits, because the parameters fall within the scope of the Criterion 2 identified in the rule: A process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The P-T limits for BWR-designed light-water reactors fall within the scope of Criterion 2 of 10 CFR 50.36(d)(2)(ii) and are therefore ordinarily required to be included within the TS LCOs for a plant-specific facility operating license. On January 31, 1996, the NRC staff issued GL 96-03 to inform licensees that they may request a license amendment to relocate the P-T limit curves from the TS LCOs into a PTLR or other licensee-controlled document that would be controlled through the Administrative Controls Section of the. TS. In GL 96-03, the NRC staff informed licensees that in order to implement a PTLR, the P-T limits for light-water reactors would need to be generated in accordance with an NRC-approved methodology and that the methodology to generate the P-T limits would need to comply with the requirements of 10 CFR Part 50, Appendices G and H; be documented in an NRC-approved topical report or plant-specific submittal; and be incorporated by reference in the Administrative Controls Section of the TS. This change implements the methodology provided in the Structural Integrity Associates report (Reference 3), which will continue to ensure compliance with Appendices G and H of the Code of Federal Regulations in conjunction with plant commitments to the BWRVIP ISP program, and the associated regulatory guidance, including TSTF-419-A, which provides TS changes. In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner; (2) such activities will be conducted in compliance with the Commission's regulations; and (3) the approval of the proposed change will not be inimical to the common defense and security or to the health and safety of the public. 6.0 Environmental Assessment A review has determined that the proposed changes do not involve: (i) a significant hazards consideration; (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite; or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed changes meet the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9).

Amendment No. 4-40,19i~ 3/4.6-11

INSERT "A" 4.6.A BASES The Pressure and Temperature Limits Report (PTLR) provides Pressure-Temperature Curves for heatup and cooldown for the reactor vessel. This report is developed in compliance with NRC approved methodology prescribed in Structural Integrity Associates Topical Report (TR) SIR-05-044-A, "Pressure -Temperature Report Methodology for Boiling Water Reactors", April 2007. The PTLR provides Pressure Test Curve A, and Heatup and Cooldown Curves B and C for 34 EFPY operation. These curves are developed in compliance with the requirements of Appendix G to 10 CFR 50 and Appendix G to ASME Section XI and the methodology in NRC approved Structural Integrity Report, SIR-05-044-A. Pilgrim reactor pressure vessel beltline, bottom head, and feedwater nozzle/upper vessel regions are evaluated. These regions bound all other regions with respect to brittle fracture, including the N2 nozzles through 34 EFPY. In addition, limiting stresses for the bottom head (CRD penetration) region were selected from all applicable design basis transients in order to accommodate any potential inadvertent bottom head cooldown events. The P-T curves for hydrostatic and leak tests, subcritical heatup and cooldown, and critical core operation, were generated with fuel in the vessel for 24, 34, 44, and 54 EFPY operations, however only the curves applicable up to 34 EFPY are included in the PTLR. Pilgrim Adjusted Reference Temperature Calculations for 24, 34, 44, and 54 EFPYs (Table 3, 4, 5, and 6). These Tables show limiting material (plates and welds) characteristics and fluence values calculated at 24, 34, 44, and 54 EFPYs of operation. Fluence is projected- based on actual operation through 20.7 EFPY (April 2005). Fluence at intermediate exposure is linearly interpolated between 20.7 and 54 EFPY. The allowable rate of heatup and cooldown for the reactor vessel contained fluid is 100'F per hour averaged over a period of one hour. This rate has been chosen based on past experience with operating power plants. The associated time periods for heatup and cooldown cycles when the 100°F per hour rate is limiting, provides for efficient, but safe, plant operation. Specific analyses were made based on a heating and cooling rate of 100°F/hour applied continuously over a temperature range of 100OF to 5460F. Calculated stresses were within ASME Boiler and Pressure Vessel Code Section III stress intensity and fatigue limits even at the flange area where maximum stress occurs. The coolant in the bottom of the vessel is at a lower temperature than that in the upper regions of the vessel when there is no recirculation flow. This colder water is forced up when recirculation pumps are started. This will not result is stresses which exceed ASME Boiler and Pressure Vessel Code, Section III limits when the temperature differential is not greater than 145 0 F. The reactor coolant system is a primary barrier against the release of fission products to the environs. In order to provide assurance that this barrier is maintained at a high degree of integrity, restrictions have been placed on the operating donditions to which it can be subjected. Appendix G to 10CFR50 defines the temperature-pressurization restrictions for hydrostatic and leak tests, pressurization, and critical operation. These limits have been calculated for Pilgrim and are contained in the PTLR.

BASES: 3/4.6 PRIMARY SYSTEM BOUNDARY A. Thermal and Pressurization Limitations The Pressure and Temperature Limits Report (PTLR) provides Pressure-Temperature Curves for heatup and cooldown for the reactor vessel. This report is developed in compliance with NRC approved methodology prescribed in Structural Integrity Associates Topical Report (TR) SIR-05-044-A, "Pressure -Temperature Report Methodology for Boiling Water Reactors", April 2007. The PTLR provides Pressure Test Curve A, and Heatup and Cooldown Curves B and C for 34 EFPY operation. These curves are developed in compliance with the requirements of Appendix G to 10 CFR 50 and Appendix G to ASME Section Xl and the methodology in NRC approved Structural Integrity Report, SIR-05-044-A. Pilgrim reactor pressure vessel beltline, bottom head, and feedwater nozzle/upper vessel regions are evaluated. These regions bound all other regions with respect to brittle fracture, including the N2 nozzles through 34 EFPY. In addition, limiting stresses for the bottom head (CRD penetration) region were selected from all applicable design basis transients in order to accommodate any potential inadvertent bottom head cooldown events. The PJT curves for hydrostatic and leak tests, subcritical heatup and cooldown, and critical core operation, were generated with fuel in the vessel for 24, 34, 44, and 54 EFPY operations, however only the curves applicable up to 34 EFPY are included in the PTLR. Pilgrim Adjusted Reference Temperature Calculations were performed for 24, 34, 44, and 54 EFPYs (Tables 3 to 6). These Tables show limiting material (plates and welds) characteristics and fluence values calculated at 24, 34, 44, and 54 EFPYs of operation. Fluence is projected based on actual operation through 20.7 EFPY (April 2005). Fluence at intermediate exposure is linearly interpolated between 20.7 and 54 EFPY. The allowable rate of heatup and cooldown for the reactor vessel contained fluid is 100°F per hour averaged over a period of one hour. This rate has been chosen based on past experience with operating power plants. The associated time periods for heatup and cooldown cycles when the 100°F per hour rate is limiting provides for efficient, but safe, plant operation. Specific analyses were made based on a heating and cooling rate of 100 0 F/hour applied continuously over a temperature range of 100°F to 5460 F. Calculated stresses were within ASME Boiler and Pressure Vessel Code Section III stress intensity and fatigue limits even at the flange area where maximum stress occurs. The coolant in the bottom of the vessel is at a lower temperature than that in the upper regions of the vessel when there is no recirculation flow. This colder water is forced up when recirculation pumps are started. This will not result is stresses which exceed ASME Boiler and Pressure Vessel Code, Section III limits when the temperature differential is not greater than 1450F. The reactor coolant system is a primary barrier against the release of fission products to the environs. In order to provide assurance that this barrier is maintained at a high degree of integrity, restrictions have been placed on the operating conditions to which it can be subjected. Appendix G to 10CFR50 defines the temperature-pressurization restrictions for hydrostatic and leak tests, pressurization, and critical operation. These limits have been calculated for Pilgrim and are contained in the PTLR. Revision 2-0-, B3/4.6-1

RPV flange criticality temperature limit (Figure 6.3: Curve C - nuclear heating): > 70 0 F. Interpreted as the temperature change in any 1-hour period is less than or equal to 25TF. 2 Interpreted as the temperature change in any 1-hour period is less than or equal'to 100TF. Pilgrim Pressure-Temperature Limits Report Revision 0 5.0 DISCUSSION, The ART of the limiting beltline material is used to adjust the beltline P-T Curves to account for irradiated effects. RG 1.99, Revision 2 (Reference 9.6) provides the methods for determining the ART. The Pilgrim reactor vessel beltline copper (Cu) and nickel (Ni) values were obtained from the evaluation of Pilgrim vessel plate and weld materials (Reference 9.3). Cu and Ni values were used with Tables 1 and 2 of RG 1.99, Revision 2 to determine a chemistry factor (CF) per Paragraph 1.1 of RG 1.99, Revision 2 for welds and plates, respectively. Where applicable, data from the BWRVIP ISP (Reference 9.8) are used to adjust CFs, as reported in Reference 9.3. TransWare Report, No.ENT-FLU-001-R-001, Revision 0, (Reference 9.2) provides Pilgrim reactor vessel fluence values using the NRC-approved RAMA methodology. Pursuant to NRC approval of implementation of the BWRVIP ISP at Pilgrim (Pilgrim License Amendment 209, Reference 9.7), Entergy has performed fluence calculations using a bias factor of 1.0, which correlates to the benchmarked Monticello surveillance capsule activation data results achieved in 2008 (Reference 9.9). Therefore, the Pilgrim fluence without the bias factor is the representative fluence for Pilgrim Nuclear Power Station. Even though the TransWare calculations for Pilgrim were performed in December 2005, which was prior to the completion of the Monticello benchmarking in 2008, there have been no material changes in the RAMA Code and associated methodology that impact the previously completed fluence calculations for Pilgrim. Therefore, Reference 9.2 provides the applicable Pilgrim reactor vessel fluence values using the RAMA methodology without the need for a bias factor. The Pilgrim fluence calculation results show the reactor vessel will experience peak ID (at the clad/base metal interface) fluence at 34 EFPY of 7.53x1 017 n/cm 2 at the Lower Intermediate Weld 1-338A/C locations, and 8.42x1 017 n/cm 2 at the Lower Intermediate Shell Plates, respectively. Even though the peak fluence occurs in the Lower Intermediate Shell Plates, Lower Shell Plate 337-01 C has a higher ART due to material chemistry effects (peak fluence = 6.96x1 017 n/cm 2 at 34 EFPY). In addition, the N2 nozzle peak fluence at 34 EFPY was calculated to be 1.90x1017 n/cm 2 (Reference 9.12), and the N1 6A/B instrument ("drill-hole" style) nozzle fluence at 34 EFPY was calculated to be 3.52x1015 n/cm 2 (Reference 9.3). Both nozzles were evaluated for their impact on the Pilgrim P-T curves, and the limits presented in this PTLR incorporate any effects of these nozzles accordingly. All fluence values at 34 EFPY are linearly interpolated from the data reported in Reference 9.2. Reference 9.3 provides ART calculations at 24, 34, 44, and 54 EFPY using extrapolated fluence based on operation to 20.7 EFPY (Reference 9.2). Material properties, initial RTNDT and CFs for all vessel plates, welds and nozzles exposed to a fluence greater than 1.0x1017 n/cm 2 are obtained from Reference 9.10, except where data is available from the ISP program. The Lower Shell Longitudinal Weld material CF has been adjusted based on ISP data reported in Reference 9.8. References 9.4'and 9.11 provide the development of the P-T Curves documented in this report. Those calculations describe the methodology used from Reference 9.1, as well as the relevant requirements of Appendix G to 10 CFR 50 (Reference 9.13) and Appendix G to ASME Section XI (Reference 9.14). As presented in the calculations, the RPV beltline, bottom head (including penetrations), non-beltline vessel regions were evaluated for brittle fracture, including the effects of the N2 and N1 6A/B nozzles. Pilgrim Pressure-Temperature Limits Report Revision 0 In accordance with Section 2.4 of Reference 9.1, the P-T curves for the Core Not Critical" (Curve B) and Core Critical (Curve C) operating conditions apply for both the 1/4t and 3/4t locations. When combining pressure and thermal stresses, it is usually necessary to evaluate stresses at the 1/4t location (inside surface flaw) and the 3/4t location (outside surface flaw), This is because the thermal gradient tensile stress of interest is in the inner wall during cooldown and is in the outer wall during heatup. However, as a conservative simplification, the thermal gradient stress at the 1/4t location is assumed to be tensile for both heatup and cooldown. This results in the approach of applying the maximum tensile stress at the 1/4t location. This approach is conservative because irradiation effects cause the allowable toughness at 1/4t to be less than that at 3/4t for a given metal temperature. This approach causes no operational constraints,-and is well above the P-T curve limits. For Core Not Critical (Curve B) and Core Critical (Curve C) conditions, the P-T curves specify a coolant heatup and cooldown temperature rate of 5100 0 F/hr for which the curves are applicable. For Hydrostatic Pressure and Leak Test (Curve A) conditions, a coolant heatup and cooldown temperature rate of <25 0 F/hr must be maintained based on the requirements of Reference 9.1. The P-T limits and corresponding limits of either Curves A or B may be applied, if necessary, while achieving or recovering from test conditions. So, although Curve A applies during pressure test conditions, the limits of Curve B may be conservatively used during pressure testing ifthe pressure test heatup and cooldown rate limits cannot be maintained. The only computer code used in the determination of the PNPS P-T curves was the ANSYS finite element computer program for the feedwater nozzle (non-beltline) and recirculation inlet nozzle (N2) stresses (various code versions as identified in References listed below). These analyses were performed to determine through-wall thermal and pressure stress distributions for the Pilgrim feedwater nozzles due to a step-change thermal transient (Reference 9.4), and for the recirculation inlet nozzles (N2) due to a shutdown transient at 100°F/hr (Reference 9.12). The ANSYS program was controlled under the vendor's 10 CFR 50 Appendix B Quality Assurance Program for nuclear quality-related work. Benchmarking consistent with NRC GL 83-11, Supplement 1 was performed as a part of the computer program verification by comparing the solutions produced by the computer code to hand calculations for several problems. The following inputs were used as input to the finite element analysis: 

               "   With respect to operating conditions, stress distributions for a thermal shock of 456 0 F represents the maximum thermal shock for the feedwater nozzle during normal operating conditions. The stress results for a 4560 F shock are appropriate for use in developing the non-beltline P-T curves based on the limiting feedwater nozzle, as a shock of 456 0 F is representative of the Turbine Roll transient that occurs in the feedwater nozzle as part of the 100°F/hr startup transient. Therefore, these stresses represent bounding stresses in the feedwater nozzle associated with 100°F/hr heatup/cooldown limits associated with the P-T curves for the upper vessel feedwater nozzle region.

The thermal stress distributions used for the recirculation inlet nozzle were those generated for a plant shutdown transient at 100F/hr. Among the series of events analyzed this event produced the maximum hoop stress (Reference 9.12).

  • Heat transfer coefficients used in the finite element analyses were those used in the original RPV stress report thermal analyses, the feedwater nozzle Pilgrim Pressure-Temperature Limits Report Revision 0 repair design specification and the reactor vessel cyclic load analysis.

(Reference 9.17) A three-dimensional finite element model was constructed for both the recirculation inlet and the feedwater nozzle evaluations. The models include a full 3600 representation of the nozzle, a section of the safe end, and the thermal sleeve. The local RPV shell included in the model extends 300 circumferentially and 40 inches longitudinally on each side of the nozzle centerline. The temperature dependent material properties used in the analyses are obtained from the ASME Code (the RPV shell, SA-533, Grade B Class 1; the nozzle and safe end, SA-508, Class 2; and the cladding and the nozzle-to-safe end weld,assumed to be Type 304 stainless steel) (References 9.12 and 9.18) Pilgrim Pressure-Temperature Limits Report Revision 0 6.0 PRESSURE-TEMPERATURE CURVES Pilgrim Pressure-Temperature Limits Report Revision 0 Figure 6.1 1,200_ 1,1000 . -.......

Pilgrim Pressure-Temperature Limits Report Revision 0 8.0 PILGRIM REACTOR VESSEL MATERIALS SURVEILLANCE PROGRAM In accordance with 10 CFR 50, Appendix H (Reference 9.15), Pilgrim has developed Reactor Vessel Material Surveillance Program Requirements (Reference 9.7), the first surveillance capsule at Pilgrim was removed in Refueling Outage (RFO) No. 4 after 4.17 EFPY of operation. The surveillance capsule contained flux wires for neutron fluence measurement, Charpy V- .Notch impact test specimens, and uniaxial tensile test specimens fabricated using materials from the vessel core beltline region. The flux wires and test specimens removed from the capsules were tested according to the latest version of ASTM El 85. The surveillance capsule activation and fluence results are discussed in Reference 9.2. Pilgrim has replaced the original RPV material surveillance program with participation in the BWRVIP ISP (Reference 9.7). This program meets the requirements of 10 CFR 50, Appendix H, and has been approved by NRC. Under the ISP, there are no further capsules scheduled for removal from the Pilgrim reactor vessel. Representative surveillance capsule materials for the Pilgrim limiting beltline plate and weld are in another representative plant with a capsule withdrawal schedule controlled by the BWRVIP ISP. There are two remaining Pilgrim specimen capsules which will remain in place to serve as backup surveillance material for the BWRVIP program, or as otherwise needed. The activation results of the RFO-4 Surveillance Capsule have not provided a comparable bench marking results with the RAMA fluence methodology. As such, Pilgrim has used Monticello benchmarking to predict the Pilgrim fluence. Pilgrim remains as a participant in the NRC-approved BWRVIP Integrated Surveillance Program and will follow those requirements. The Pilgrim Reactor Vessel Material Surveillance Program is discussed in the Pilgrim UFSAR, Appendix M (Reference 9.16). Pilgrim Pressure-Temperature Limits Report Revision 0
