3.0 Background
By letter dated November 1 7, 201 1 (Agencywide Documents Access and Management System (ADAMS) Accession No. M L 1 1 3260534}, the Boiling Water Reactor Owners' Group (BWROG) submitted Licensing Topical Report (LTR) BWROG-TP- 1 1 -022, Revision 1 , "Pressure Temperature Limits Report Methodology for Boiling Water Reactors," to the U.S. Nuclear Regulatory Commission (NRC) staff. By letter dated May 1 6, 201 3 (Reference 1 ), the N RC staff found that TR BWROG -TP- 1 1 -022, Revision 1 , "is acceptable for referencing in licensing applications for boiling water reactors to the extent specified and under the limitations delineated in the TR and in the enclosed final SE. The final SE defines the basis for our acceptance of the TR." This Safety Evaluation Report (SER) permits Boiling Water Reactor (BWR) licensees to relocate their P-T curves from the facility TS to a Pressure and Temperature Limits Report ( PTLR) utilizing the guidance in TS Task Force (TSTF) Traveler No. 4 1 9-A. The BWROG issued the final report (-A) on September 4, 201 3 (Reference 2) which contains the E 1 -1 to NL- 1 3- 1 773 Description and Assessment final SER, along with the NRC requests for additional information (RAis) , and the BWROG's responses to the NRC RAis.
LTR BWROG-TP- 1 1 -022, Revision 1 , is a revision of LTR S I R 044-A with the same title, and contains minor modifications of the P-T limit methodology. As was the case for LTR S I R 044-A, the BWROG provided this LTR to support the BWR licensees to relocate their P -T curves and associated numerical values (such as heatup I cooldown rates) from facility TS to a PTLR, a licensee-controlled document, using the guidelines provided in Generic Letter (GL) 96-03, "Relocation of the Pressure Temperature Limit Curves and Low Temperature Overpressure Protection System Limits."
The N RC SER contained one condition for future potential applicants to address in their application of this LTR to their plant-specific P-T limits or PTLR submittal:
Each applicant referencing this LTR shall confirm that, in addition to the requirements in the ASME Code,Section XI, Appendix G , the lowest service temperatures for all ferritic RCPB components that are not part of the RPV, are below the lowest operating temperature in the proposed P-T limits.
This condition is discussed in the Technical Analysis section of this LAR.
By letter dated November 1 7, 20 1 1 (ADAMS Accession No. ML113250288) the BWROG submitted LTR BWROG-TP- 1 1 -023, Revision 0, "Linear Elastic Fracture Mechanics (LEFM)
Evaluation of General Electric Boiling Water Reactor Water Level I nstrument (WLI) Nozzles for Pressure-Temperature (P-T) Curve Evaluations", to the U.S. N RC staff for review and acceptance for referencing i n subsequent licensing actions. By letter dated March 1 4, 201 3, (Reference 3) the NRC staff has found that TR BWROG -TP- 1 1 -023, Revision 0, "is acceptable for referencing in licensing applications for boiling water reactors to the extent specified and under the limitations delineated in the TR and in the enclosed final SE. The final SE defines the basis for our acceptance of the TR." This SER permits BWR licensees to use BWROG -TP- 1 1 -
023, Revision 0 as an acceptable methodology to obtain plant-specific stress i ntensity factors for an internal pressure load case and a 1 00 aF/hr thermal ramp load case for use in developing plant-specific P-T limit curves for reactor pressure vessel (RPV) water level instrument (WLI) nozzles. Since the analyses assumed that Alloy 600 material was used for the weld metal for all nozzles, the BWROG revised the LTR to limit the application of this LTR to only WLI nozzle configuration/design using Alloy 600 material for the weld metal. The NRC SER did not contai n any additional conditions or limitations with regard to this LTR. The BWROG issued the final report (-A) on June 28, 201 3 (Reference 4) which contains the final SER, along with the NRC requests for additional information (RAis) and the BWROG's responses to the NRC RAis.
TS Task Force (TSTF) Traveler No. 4 1 9 (Reference 6) amended the Standard TS (NUREGs-1 430, - 1 431 , - 1 433, and - 1 434) to: ( 1 ) delete references to the TS LCO specifications for the P T limits in the TS definition for the PTLR, and (2) revise STS 5.6.6 to identify, by number and title, NRC-approved topical reports that document PTLR methodologies, or the NRC safety evaluation for a plant-specific methodology by NRC letter and date. A requirement was added to the reviewers note to specify the complete citation of PTLR methodology in the plant specific PTLR, including the report number, title, revision, date, and any supplements. Only the figures, values, and parameters associated with the P-T limits are relocated to the PTLR. The TSTF also specified that the methodology, and any subsequent changes, must be reviewed and E 1 -2 to NL- 1 3- 1 773 Description and Assessment approved by the NRC. In this case, the methodology was approved in the Reference 1 and 3 letters.
The H N P U nit 1 and Unit 2 PTLRs, based on the methodology provided in BWROG-TP- 1 1 -022-A, Revision 1 and BWROG-TP- 1 1 -023-A, Revision 0, and based on the template provided in BWROG-TP- 1 1 -022-A, Revision 1 , are being submitted for review. The purpose of the HNP PTLRs is to present operating limits related to Reactor Coolant System (RCS) pressure versus temperature limits during heatup, cooldown and hydrostatic/class 1 leak testing.
4.0 Technical Analysis N RC G L 96- 03 (Reference 5) 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 TS 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 TS to a PTLR. As one of the improvements to the STS, the N RC staff agreed with the industry that the curves may be relocated outside the plant TS 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 be NRC approved, and that the associated LTR for such approval is referenced in the plant TS. Based on this prerequisite, the purpose of the BWROG L TRs is to provide BWRs with NRC -approved L TRs that can be referenced in plant TS to establish BWR fracture mechanics methods for generating P-T curves/limits that allow BWR plants to adopt the PTLR option.
Historically, utilities that own BWRs have submitted license amendment requests to update their P-T curves. In addition, the current situation causes both the regulator and licensees to expend resources that could otherwise be devoted to other activities. The objective of BWROG LTRs is to avoid these situations by providing P-T curve methods that are generically approved by the N RC 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 N RC, and must be referenced in the Administrative Controls section of the plant Technical Specifications. The LTRs provide the current BWROG methodology for developing RCS pressure test, core not critical, and core critical P-T curves for BWRs.
As discussed in Section 2.0 of the Reference 1 , 1 0 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 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 i nservice leak rate testing and/or hydrostatic testing conditions).
BWROG -TP- 1 1 -022, Revision 1 was prepared by Structural I ntegrity Associates (SIR-05-044, Revision 1 ) and has sections and appendices identical to its previous edition, LTR S I R- 05-044-A. Since Revision 1 contains only limited modifications when compared with the previous edition, the NRC SE focuses on these modifications (excluding editorial changes) and does not repeat the evaluation of the Revision 1 contents which have been discussed and accepted in E 1 -3 to NL- 1 3- 1 773 Description and Assessment the N RC SE for the previous edition (LTR-S I R-04-055-A) . As discussed in the NRC SE for LTR-05-044-A, Section 1 .0 of S I R-05-044 (and therefore of S I R-05-044 Revision 1 ) describes the background and purpose for the L TR. 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 8 provides a template PTLR.
The SER that approves BWROG-TP- 1 1 - 022 Revision 1 contains the fol lowing condition:
Each applicant referencing this LTR shall confirm that, in addition to the requirements in the ASME Code,Section XI , Appendix G, the lowest service temperatures for all ferritic RCPB components that are not part of the RPV, are below the lowest operating temperature in the proposed P-T limits.
HNP has evaluated this condition, and has determined it to be addressed for PTLR curves provided for both Unit 1 and Unit 2.
BWROG -TP- 1 1 -023, Revision 0 was also prepared by Structural I ntegrity Associates (0900876 .40 1 . RO). The SER that approves BWROG-TP- 1 1 -023 Revision 0 states "the staff determined that no conditions or limitations are necessary for future applicants to address in their application of this LTR to their plant-specific P -T limit submittals". Section 1 , "Introduction,"
provides the relationship among P-T limits, PTLR, and the proposed LEFM evaluation for WLI nozzles. Section 2, "Methodology," provides the proposed LEFM methodology, starting from the stress analysis based on the finite element method (FEM) to the LEFM analysis based on the boundary integral/influence function (BIE/IF) method. Section 3, "Assumptions," provides assum ptions adopted in each step of the proposed methodology, such as the heat transfer coefficients for the WLI nozzle and RPV external and internal surfaces, material properties for various components, and the stress free temperature for evaluating cladding stresses. Section 4, "Finite Element Model," provides information on development of the 38 FEM models first introduced in Section 2, considering various types of nozzle and FEM models with and without a crack. This section also addressed FEM model validation through mesh density check for models with and without a crack. Section 5, "Instrument Nozzle Load Cases," addresses the loads on the nozzle: internal pressure, thermal transient, and pipe reaction load. Section 6, "Pressure, Thermal, and Piping Load Results," presents FEM results (i.e., stressors and applied stress intensity factors (K1s)) under these three types of load. Section 7, "Observations and Discussions," offers the BWROG's observation of the behavior of the applied K1 and a discussion of the modeling choices that could affect the results. Section 8, "Generic Methodology for K1 Estimation," provides generic K1 Formulas derived from the FEM results for a variety of nozzles for licensees to use for WLI nozzles in their plant-specific P-T limit applications. Section 9, "Summary," provides summary findings and conclusions.
E 1 -4 to N L- 1 3- 1 773 Description and Assessment Regulatory Safety Analysis 4.1 No Significant Hazards Consideration SNC has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 1 0 CFR 50.92, "Issuance of amendment," as d iscussed 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 Edwin I . Hatch Nuclear Plant (HNP) Unit 1 and Unit 2 Technical Specifications (TS) Section 1 .0 ("Definitions"), Limiting Conditions for Operation and Surveillance Requirement Applicability Section 3.4.9 ("RCS Pressure and Temperature (PIT) Limits"), and Section 5.0 ("Administrative Controls"), to delete reference to the pressure and temperature curves, and to include reference to the Pressure and Temperature Limits Report (PTLR). This change adopts the methodology of BWROG-TP-1 1 - 022-A, Revision 1 (SI R-05-044, Revision 1 -A), "Pressure-Temperature Limits Report Methodology for Boiling Water Reactors", dated June 201 3, and of BWROG -TP- 1 1 -023-A, Revision 0 (0900876.401 , Revision 0-A), "Linear Elastic Fracture Mechanics Evaluation of General Electric Boiling Water Reactor Water Level Instrument Nozzles for Pressure Temperature Curve Evaluations", dated May 201 3 , for preparation of the pressure and temperature curves, and incorporates the guidance of TSTF-4 1 9-A, "Revise PTLR Definition and References in ISTS 5.6.6, RCS PTLR". The HNP PTLRs have been developed based on the methodologies provided in BWROG -TP- 1 1 -022-A, Revision 1 and BWROG -TP- 1 1 -
023-A, Revision 0, and based on the template provided in BWROG-TP- 1 1 -022-A, Revision 1 . The HNP PTLRs meet all Conditions specified in the Safety Evaluation Reports (SERs) for BWROG-TP- 1 1 -022-A, Revision 1 and for BWROG-TP- 1 1 -023-A, Revision 0.
The NRC has established requirements in Appendix G to 1 0 CFR 50 in order to protect the integrity of the reactor coolant pressure boundary (RCPB) in nuclear power plants.
Additionally, the regulation in 1 0 CFR Part 50, Appendix H , provides the NRC staff's criteria for the design and implementation of reactor pressure vessel (RPV) material surveillance programs for operating lightwater reactors. I mplementing these NRC approved methodologies 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. I ncorporation of the new methodologies 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 E 1 -5 to NL- 1 3-1 773 Description and Assessment 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.
- 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 setpoints at which protective actions are initiated, and there is no change to the operability requirements for equipment assumed to operate for accident mitigation. Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based upon the above, SNC concludes that the proposed amendment presents no significant hazards consideration under the standards set forth in 1 0 CFR 50.92(c), and, accordingly, a finding of no significant hazards is justified.
4.2 Applicable Regulatory Requirements I Criteria The N RC has established requirements in Appendix G of Part 50 to Title 1 0 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 1 0 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 XI 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 1 0 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 1 0 CFR Part 50, Appendix G provides the NRC staff's 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 1 0 CFR Part 50, Appendix H, provides the NRC staff's criteria for the design and implementation of RPV material surveillance programs for operating lightwater reactors.
HNP Units 1 and 2 demonstrates its compliance with the Appendix H through participation in the BWRVI P I ntegrated Surveillance Program (ISP) (Reference 7).
E 1 -6 to NL-1 3- 1 773 Description and Assessment In March 200 1 , the NRC staff issued RG 1 . 1 90, "Calculational and Dosimetry M ethods 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 . 1 90.
Section 1 82a of the Atomic Energy Act of 1 954 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 i n 1 0 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 1 0 CFR 50.36(c)(2)(ii)(B) 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 1 0 CFR 50.36(c)(2)(ii)(B) and are therefore ordinarily required to be included within the TS LCOs for a plant-specific facility operating license. On January 31 , 1 996, 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 1 0 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 I ntegrity Associates reports (References 2 and 4), which will continue to ensure compliance with Appendices G and H of the Code of Federal Regulations in conjunction with plant commitments to the BWRVI P ISP program, and the associated regulatory guidance, including TSTF-41 9-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.
5.0 Environmental Assessment A review has determined that the proposed changes would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 1 0 CFR 20, or would change an inspection or surveillance requirement. However, the proposed changes do not involve: (i) a significant hazards consideration; (ii) a significant change in the E1 -7 to N L- 1 3- 1 773 Description and Assessment 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 1 0 CFR 51 .22(c)(9). Therefore, pursuant to 1 0 CFR 51 .22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed changes.
6.0 Precedent This change is generally consistent with the changes to the Improved TS described in TSTF-4 1 9-A, (Reference 6). Plants which have received approval for similar changes, in whole or in part, are listed below:

Edwin I. Hatch Nuclear Plant Application for Amendment to Technical Specifications Regarding Relocation of Pressure and Temperature (P-T) Curves to the Pressure and Temperature Limits Report (PTLR) Consistent with TSTF-419-A Enclosure 4 Proposed Technical Specification Bases Changes (Marked-Up)
RCS PIT Limits B 3.4.9 B 3.4 REACTOR COOLANT SYSTEM (RCS)
B 3.4.9 RCS Pressure and Temperature (PIT) Limits BASES BACKGROUND All components of the RCS are designed to withstand effects of cyclic loads due to system pressure and temperature changes. These loads are introduced by startup (heatup) and shutdown (cooldown) operations, power transients, and reactor trips. This LCO limits the pressure and temperature changes during RCS heatup and cooldown, within the design assumptions and the stress limits for cyclic operation.
This SpesifisationT he PTLR contains PIT limit curves for non- nuclear heatup and cooldown, and inservice leakage and hydrostatic testing, and also limits the maximum rate of change of reactor coolant temperature. The criticality curve provides limits for both nuclear heatup and criticality.
Each PIT limit curve defines an acceptable region of operation for a particular operating condition. The usual use of the curves is operational guidance during heatup or cooldown maneuvering, when pressure and temperature indications are monitored and compared to the applicable curve to determine that operation is within the allowable region.
The LCO establishes operating limits that provide a margin to brittle failure of the reactor vessel and piping of the reactor coolant pressure boundary (RCPB). The vessel is the component most subject to brittle failure. Therefore, the LCO limits apply mainly to the vessel.
1 0 CFR 50, Appendix G (Ref. 1 ) requires the establishment of PIT limits for material fracture toughness requirements of the RCPB materials. Reference 1 requires an adequate margin to brittle failure during normal operation, anticipated operational occurrences, and system hydrostatic tests. It mandates the use of the ASM E Code,Section I l l , Appendix G (Ref. 2).
The actual shift in the RTNor of the vessel material is established periodically by removing and evaluating the irradiated reactor vessel material specimens, in accordance with ASTM E 1 85 (Ref. 3) and Appendix H of 1 0 CFR 50 (Ref. 4), and the BWR Vessel and Internals Project (VIP) Integrated Surveillance Program OSP) lRef. 1 4). The operating PIT limit curves are adjusted, as necessary, based on the evaluation findings and the recommendations of Reference 5.
(continued)
HATCH UNIT 1 B 3.4-39 REVISION 1 2
RCS PIT Limits B 3.4.9 BASES BACKGROUND The PIT limit curve for inservice leak and hydrostatic testing, and the (continued) curve for non-nuclear heatup and cooldown include separate curves for the bottom head, beltline, and upper vessel and flange regions.
These curves are derived from stress analysis of these vessel regions.
The criticality limits include the Reference 1 requirement that they be at least 40°F above the heatup curve or the cooldown curve and not lower than the minimum permissible temperature for the inservice leakage and hydrostatic testing.
The consequence of violating the LCO limits is that the RCS has been operated under conditions that can result in brittle failure of the RCPB, possibly leading to a nonisolable leak or loss of coolant accident. In the event these limits are exceeded, an evaluation must be performed to determine the effect on the structural integrity of the RCPB components. ASM E Code,Section XI, Appendix E (Ref. 6), provides a recommended methodology for evaluating an operating event that causes an excursion outside the limits.
APPLICABLE The PIT limits are not derived from Design Basis Accident (DBA)
SAFETY ANALYSES analyses. They are prescribed during normal operation to avoid encountering pressure, temperature, and temperature rate of change conditions that might cause undetected flaws to propagate and cause nonductile failure of the RCPB, a condition that is unanalyzed.
References 8 and 12 aroved the muves and limits sesified in this section. References 8 and 1 2 establish the methodology for Q.etermining the PIT limits. Since the PIT limits are not derived from any DBA, there are no acceptance limits related to the PIT limits.
Rather, the PIT limits are acceptance limits themselves since they preclude operation in an unanalyzed condition.
RCS PIT limits satisfy Criterion 2 of the NRC Policy Statement (Ref. 9).

BASES LCO b. The temperature difference between the reactor vessel bottom (continued) head coolant and the reactor pressure vessel (RPV) coolant is s 1 45°F during recirculation pump startup;
- c. The temperature difference between the reactor coolant in the respective recirculation loop and in the reactor vessel is s 50°F during recirculation pump startup;
- d. RCS pressure and temperature are within the criticality limits specified in F'ig1:1re 3.4.Q Jthe PTLR, prior to achieving criticality; and
- e. The reactor vessel flange and the head flange temperatures are > 7e0F'with in the limits soeci.fuld in the PTLR when tensioning or detensioning the reactor vessel head bolting studs.
- f. The reactor vessel flange and head flange temperatures are A: 7e0F'within the limits specified in the PTLR when the reactor vessel head is tensioned.
- g. For the case when the vessel head i s either off o r on but not tensioned and fuel is in the vessel, all three sections of the vessel (upper vessel, beltline, and bottom head) may be lowered to a minimum of 68°F. When the head is being tensioned, or is already tensioned, the beltline and bottom head regions may be lowered to 68°F, as long as there is not any pressure or heatup/cooldown. The upper vessel, however, has a higher minimum temperature requirement with the head tensioned, as previously delineated.
The 68°F temperature is based on fuel shutdown margin considerations, since this is a more restrictive temperature than would be obtained from 1 0 CFR 50, Appendix G, considerations. With no fuel in the vessel, the temperature may drop to as low as 40°F, because this is the highest qualification temperature to meet toughness requirements for all reactor materials.
These limits define allowable operating regions and permit a large number of operating cycles while also providing a wide margin to nonductile failure.
The rate of change of temperature limits controls the thermal gradient through the vessel wall and is used as input for calculating the heatup, cooldown, and inservice leakage and hydrostatic testing PIT limit curves. Thus, the LCO for the rate of change of temperature restricts stresses caused by thermal gradients and also ensures the validity of the PIT limit curves.

RCS Pff Limits B 3.4.9 B 3.4 REACTOR COOLANT SYSTEM (RCS)
B 3.4.9 RCS Pressure and Temperature (Pff) Limits BASES BACKGROUND All components of the RCS are designed to withstand effects of cyclic loads due to system pressure and temperature changes. These loads are introduced by startup (heatup) and shutdown (cooldown) operations, power transients, and reactor trips. This LCO limits the pressure and temperature changes during RCS heatup and cooldown, within the design assumptions and the stress limits for cyclic operation.
This SpeoifioatienT he PTLR contains Pff limit curves for non- nuclear heatup and cooldown, and inservice leakage and hydrostatic testing, and also l imits the maximum rate of change of reactor coolant temperature. The criticality curve provides limits for both nuclear heatup and criticality.
Each Pff limit curve defines an acceptable region of operation for a particular operating condition. The usual use of the curves is operational guidance during heatup or cooldown maneuvering, when pressure and temperature indications are monitored and compared to the applicable curve to determine that operation is within the allowable region.
The LCO establishes operating limits that provide a margin to brittle failure of the reactor vessel and piping of the reactor coolant pressure boundary (RCPB). The vessel is the component most subject to brittle failure. Therefore, the LCO limits apply mainly to the vessel.
1 0 CFR 50, Appendix G (Ref. 1 ), requires the establishment of Pff limits for material fracture toughness requirements of the RCPB materials. Reference 1 requires an adequate margin to brittle failure during normal operation , anticipated operational occurrences, and system hydrostatic tests. It mandates the use of the ASME Code,Section I l l , Appendix G (Ref. 2).
The actual shift in the RTN DT of the vessel material is established periodically by removing and evaluating the irradiated reactor vessel material specimens, in accordance with ASTM E 1 85 (Ref. 3) and Appendix H of 1 0 CFR 50 (Ref. 4). and the BWR Vessel and Internals Eroject <VIP) Integrated Surveillance Program !ISP) <Ref. 14). The operating Pff limit curves are adjusted, as necessary, based on the evaluation findings and the recommendations of Reference 5.

HATCH UNIT 2 B 3.4-40 REVISION 77
RCS Pff Limits B 3.4.9 BASES BACKGROUND The Pff limit curve for inservice leak and hydrostatic testing, and the (continued) curve for non-nuclear heatup and cooldown include separate curves for the bottom head, beltline, and upper vessel and flange regions.
These curves are derived from stress analysis of these vessel regions.
The criticality limits include the Reference 1 requirement that they be at least 40°F above the heatup curve or the cooldown curve and not lower than the minimum permissible temperature for the inservice leakage and hydrostatic testing.
The consequence of violating the LCO limits is that the RCS has been operated under conditions that can result in brittle failure of the RCPB, possibly leading to a nonisolable leak or loss of coolant accident. I n the event these limits are exceeded, an evaluation must b e performed to determine the effect on the structural integrity of the RCPB components. ASM E Code,Section XI, Appendix E (Ref. 6), provides a recommended methodology for evaluating an operating event that causes an excursion outside the limits.
APPLICABLE The Pff limits are not derived from Design Basis Accident (DBA)
SAFETY ANALYSES analyses. They are prescribed during normal operation to avoid encountering pressure, temperature, and temperature rate of change conditions that might cause undetected flaws to propagate and cause nonductile failure of the RCPB, a condition that is unanalyzed.
References 8 and 12 approved the cblrves and limits specified in this section. References 8 a.rul.12 establish the methodology for determining the Pff limits. Since the Pff limits are not derived from any DBA, there are no acceptance limits related to the Pff limits.

The rev ised PTLR shall be submitted to the NRC upon issuance.

Hatch Unit I PTLR Revision 0 Page 6 of 40 be made without prior NRC approval. Such analysis and revisions shall be submitted to the NRC for review prior to incorporation into the PTLR.
4.0 Operating Limits The pressure-temperature (P-T) curves included in this report represent steam dome pressure versus minimum vessel metal temperature and incorporate the appropriate non-beltline limits and irradiation embrittlement effects in the beltl ine region.
The operating limits for pressure and temperature are required for three categories of operation:
(a) hydrostatic pressure tests and leak tests, referred to as Curve A; (b) core not critical operation, referred to as Curve 8; and (c) core critical operation, referred to as Curve C.
Complete P-T curves were developed for 3 8 EFPY and 49.3 EFPY for HNP- 1 as documented in Reference [8] . The HNP- 1 P-T curves for 38 EFPY are provided in Figures I through 3, and a tabulation of the overall composite curves (by region) is included in Tables I through 3 . The HNP- 1 P-T curves for 49.3 EFPY are provided in Figures 4 through 6, and a tabulation of the overall composite curves (by region) is included in Tables 4 through 6. The adjusted reference temperature (ART) values for the HNP- 1 vessel beltline materials are shown in Table 7 for 3 8 EFPY and Table 8 for 49.3 EFPY, taken from Reference [7] . The resulting P-T curves are based on the geometry, design and materials information for the HNP- 1 vessel with the fol lowing conditions :
- Heat-up/Cool-down rate limit during Hydrostatic Class I Leak Testing (Figures I and 4 :
1 Curve A) : 25 "F/hour [8].
- Normal Operating Heat-up/Cool-down rate l imit (Figures 2 and 5 : Curve 8 - non 2
nuclear heating, and Figures 3 and 6: Curve C - nuclear heating): I OO"F/hour [8].
1 Interpreted as the temperature change in any 1 -hour period is less than or equal to 25°F.
2 Interpreted as the temperature change in any 1 -hour period is less than or equal to 1 00°F.
Hatch Unit I PTLR Revision 0 Page 7 of 40
- Minimum bolt-up temperature limit 2: 76.F [8].
To address the N RC condition regarding lowest service temperature in Reference [ 1 ], the m inimum temperature is set to 76 °F, which is equal to the RTNDT. max + 60 °F, for all curves.
This value is consistent with the previous minimum temperature limits developed in [9], and is higher than previous minimum bolt-up specified in [ 1 0] .
The composite P-T curves are extended below 0 psig to - 1 4.7 psig based on the evaluation documented in Reference [ I I ], which demonstrates that the P-T curves are applicable to negative gauge pressures. Since the P-T curve calculation methods used do not specifically apply to negative values of pressure, the tabulated results start at 0 psi g. However, the minimum RPV pressure is - 1 4. 7 psig.
5.0 Discussion The adjusted reference temperature (ART) of the lim iting beltline material is used to adjust beltl ine P-T curves to account for irradiation effects. RG 1 .99 [6] provides the methods for determining the ART. The RG 1 .99 methods for determining the l imiting material and adjusting the P-T curves using ART are discussed in this section.
The vessel beltline copper (Cu) and nickel (Ni) values were obtained from the evaluation of the HNP- 1 vessel plate, weld, and forging materials [7]. The Cu and Ni values were used with Table 1 of RG 1 .99 [6] to determine a chemistry factor (CF) per Paragraph 1 . 1 of RG 1 .99 for welds.
The Cu and Ni values were used with Table 2 of RG 1 .99 to determine a CF per Paragraph 1 . 1 of RG 1 .99 for plates and forgings. However, for materials where credible surveillance data exists, a fitted CF may be used if it bounds the RG I . 99 CF.
18 2 The peak RPV I D fluence value of 2.43 x 1 0 n/cm at 3 8 EFPY was developed in Reference [7]
based on l i near interpolation between reported fluence values for 28.4 EFPY and 49.3 EFPY from Reference [5], which were calculated in accordance with RG 1 . 1 90 [4] . The peak RPV ID 18 2 tl uence value of 3 .08 x 1 0 n/cm at 49.3 EFPY was obtained from Reference [5] and was
Hatch Unit 1 PTLR Revision 0 Page 8 of 40 calculated in accordance with RG 1 . 1 90. These fluence values apply to the limiting beltline lower intermediate she l l plate (Heat No. C4 1 1 4-2). The fluence values for the limiting lower intermediate shell plate are based upon an attenuation factor of 0.724 for a postulated 1 /4T flaw.
As a result, the 1 /4T fluence for 38 EFPY and 49.3 EFPY for the limiting lower intermediate 18 2 2 shell plate are 1 .76 x 1 0 n/cm and 2.23 x 1 0 1 8 n/cm , respectively, for HNP- 1 .
The water level instrument (WLI) nozzle is located in the lower intermediate shell beltl ine plates
[8] . The limiting fluence values are as described in the paragraph above. Based on the ART evaluation in Reference [7], the recirculation inlet and outlet nozzles do not exist in the beltline regton.
The P-T curves for the core not critical and core critical operating conditions at a given EFPY apply for both the 1 /4T (inside surface flaw) and 3/4T (outside surface flaw) locations. When combining pressure and thermal stresses, it is usual ly necessary to evaluate stresses at the 1 /4T and the 3/4T locations. Thi s is because the thermal gradient tensile stress of interest is in the inner wal l during cool-down and is in the outer wal l during heat-up. However, as a conservative simplification, the thermal gradient stresses at the 1 /4T location are assumed to be tensile for both heat-up and cool-down. This results in the approach of applying the maximum tensile stresses at the 1 /4T location. This approach is conservative because irradiation effects cause the allowable toughness at the 1 /4T to be less than that at 3/4T for a given metal temperature. This approach causes no operational d ifficulties, since the BWR is at steam saturation conditions during normal operation, which is well above the P-T curve limits.
For the core not critical curve (Curve B) and the core critical curve (Curve C), the P-T curves specify a coolant heat-up and cool-down temperature rate of :S 1 oo*F /hr for which the curves are appl icable. However, the core not critical and the core critical curves were also developed to bound Service Level A/B RPV thermal transients. For the hydrostatic pressure and leak test curve (Curve A), a coolant heat-up and cool-down temperature rate of :S 25 .F/hr must be

The P-T limits and corresponding l imits of e ither Curve A or B may be applied, if necessary, while achieving or recovering from test conditions. So, although Curve A applies during pressure testing, the limits of Curve B may be conservatively used during pressure testing if the pressure test heat-up/cool-down rate l imits cannot be maintained.
The initial RTN DT, the chemistry (weight-percent copper and nickel) and ART at the l /4T 17 2 location for all RPV beltl ine materials s ignificantly affected by fluence (i.e., fluence > 1 0 n/cm for E > 1 MeV) are shown in Table 7 for 3 8 EFPY and Table 8 for 49.3 EFPY [7]. The initial RTNDT values shown in Tables 7 and 8 have been previously approved for use by the NRC per Reference [ 1 9] .
Per Reference [7] and i n accordance with Appendix A of Reference [ 1 ] , the HNP- 1 representative weld and plate survei llance materials data were reviewed from the Boiling Water Reactor Vessel and I nternals Project (BWRV l P) Integrated Survei llance Program (ISP) [ 1 2] .
The fitted C F for the limiting plate (Heat No. C4 1 1 4-2), which is based on credible surveil lance data, in the HN P- 1 vessel bounds the RG 1 .99 CF [ 1 2] . Therefore, the fitted CF is used for the l i m iting beltline plate. In addition, an archival plate heat (Heat No. C3985-2) from the HNP- 1 vessel was included in the Supplemental Surveil lance program (SSP) and irradiated data from SSP Capsules H and C are provided in Reference [ 1 2] . These data are also determined to be credible, and, consequently, a reduced margin term is used for this material as well. The HNP- 1 representative weld material (2029 1 ) is contained in the Cooper and S S P Capsule C capsules [7, 1 2] . Reference [ 1 2] contains surveillance capsule test results for the HNP- 1 representative weld material; however, since the material heats for the HNP- 1 limiting weld material and representative survei l lance capsule weld material do not match, the CF calculated using the RG 1 .99 [6] tables is used.
The ANSYS finite e lement computer program was used to develop the stress distributions through the feedwater (FW) nozzle [ 1 3 ] . These stress distributions were used in the
Hatch Unit 1 PTLR Revision 0 Page 1 0 of 40 determination of the stress intensity factors for the F W nozzles [ 1 4] . At the time the analyses were performed, the ANSYS program was controlled under the vendor' s 1 0 CFR 50 Appendix 8
[ 1 5] Quality Assurance Program for nuclear quality-related work.
The plant-specific HNP- 1 FW nozzle analysis was performed to determine stress intensity factors due to through-wall pressure stress distributions and thermal stress distributions due to bounding thermal transients [ 1 4] . Pressure and thermal stress distributions were taken from Reference [ 1 3] . Detailed information regarding the analysis can be found in References [ 1 3 , 1 4] .
The fol lowing summarizes the development of the thermal and pressure stress intensity factors for the FW nozzle [ 1 4] :
- With respect to thermal stresses, the thermal shock which represents the maximum thermal shock for the FW nozzle during normal and upset operating conditions was analyzed [ 1 3] . The thermal stress distribution, corresponding to the limiting time point presented in [ 1 3 ], along a I in ear path through the nozzle corner is used [ 1 4]. Leakage is considered in the heat transfer calculations [ 1 3] . The thermal down shock of 450°F produces the highest tensile stresses at the 1 /4T location. The B I E/IF methodology presented in the SI P-T Curve LTR [ 1 ] is used to calculate the thermal stress intensity, Kn, due to the thermal shock by fitting a third order polynomial equation to the path stress distribution for the thermal shock load case [ 1 4] . Because operation is along the saturation curve, the resulting KIT can be linearly scaled to determine the KIT to reflect the worst-case step change due to the available temperature difference. It is recognized that at low temperatures, the available temperature difference is insignificant and could potentially result in a near zero stress distribution. Therefore, a minimum KIT is calculated based on the thermal ramp of 1 00°F /hr, which is associated with the shutdown transient [ 1 4] . The resulting combination of the thermal down shock and thermal ramp Kn values represent the bounding thermal stress intensity factors in the FW nozzle associated with the P-T curves for the non-beltline region.
Hatch Unit 1 PTLR Revision 0 Page 1 1 of 40
- Boundary conditions and heat transfer coefficients used for the thermal stress analysis are as described Reference [ 1 3a] . Overall heat transfer coefficients representative of a triple sleeve sparger with Seal No. 1 failed were applied [ 1 3 a] .
- With respect to pressure stresses, a unit pressure of 1 000 psig was applied to the internal surfaces of the finite element model (FEM) [ 1 3] . The pressure stress distribution was taken along the same path as the thermal stress distribution. Recognizing that the Reference [ 1 3] evaluation was performed using a 2-0 axi-symmetric finite element model (FEM) and that it is known that the stress intensification caused by the nozzle geometry is under predicted in a 2-D axi-symmetric representation of the nozzle, a correction factor was applied to the stresses obtained from the 2-0 axi-symmetric FEM as described in Reference [ 1 4] . The B I E/I F methodology presented in the S I P-T Curve LTR [ 1 ] is used to calculate the pressure stress intensity factor, K1p, by fitting a third order polynomial equation to the path stress distribution for the pressure load case. The resulting K1p can be linearly scaled to determine the KIP for various RPV internal pressures.
- Material properties were taken from the HNP- 1 code of construction [ 1 6] . Use of temperature dependent material properties is expected to have minimal impact on the results of the analysis.
The fol lowing summarizes the development of the thermal and pressure stress intensity factors for the COP nozzle [ 1 4] :
- The KIT term is calculated using the ASME XI, Non-mandatory Appendix G, Paragraph G-22 1 4.3 [ 1 7] methodology for a heat-up/cool-down rate of 1 00 *F /hr as described in Reference [ 1 4] .
- The K1P is calculated [ 1 4] using the WRC 1 75 methodology [ 1 8] .

Hatch Unit I PTLR Rev ision 0 Page 40 of 40 Appe n dix A HATCH UNIT 1 REACTOR VESSEL MATERIALS SURVEILLANCE PROGRAM In accordance with I 0 CFR 50, Appendix H, Reactor Vessel Material Surveillance Program Requirements, two surveillance capsules have been removed from the Hatch Nuclear Plant Unit I (HNP- I ) reactor vessel. The first capsule was removed in I 984 after 5 .75 EFPY and the second was removed in I 996 after 1 4.3 EFPY [20] . The surveil lance 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 materials within the core beltline region [20] .
Southern Nuclear Operating Company committed to use the ISP in the amendments issued by the NRC regarding the implementation of the Boil ing Water Reactor Vessel and Internals Project Reactor Pressure Vessel Integrated Surveillance Program, dated March I O, 2003 [2 I ] . The BWRVIP ISP meets the requirements of 1 0 CFR 50, Appendix H, for I ntegrated Surveil lance Programs, and has been approved by N RC for the period of extended operation [22]. HNP- I continues to be a host plant under the I S P [ I 2] . Two more HNP- I capsules are scheduled to be removed and tested under the ISP in approximately 20 I 6 and 2029.

Hatch Unit 2 PTLR Rev ision 0 Page 4 of 40 1 .0 Purpose The purpose of the Hatch N uclear Plant, Unit 2 (HNP-2) Pressure and Temperature Limits Report (PTLR) is to present operating limits relating to:
I . Reactor Coolant System (RCS) Pressure versus Temperature limits during Heat-up, Cool down and Hydrostatic/Class I Leak Testing;
This report has been prepared in accordance with the requirements of Licensing Topical Reports SIR-05-044, Revision I [ I ] and 0900876.40 I , Revision 0 [2] .
2.0 Appli cability This report is applicable to the HNP-2 RPV for up to 37 and 50. 1 Effective Full-Power Years (EFPY) (3] .
The fol lowing HNP-2 Technical Specifications (TS) are affected by the information contained in this report:
- Limiting Condition for Operation and Surveillance Requirement 3 .4.9 ("RCS Pressure and Temperature (P/T) Limits")
Hatch Unit 2 PTLR Revision 0 Page 5 of 40 3.0 Methodology The limits in this report were derived as follows:
1 . The methodology used is in accordance with Reference [ 1 ] and Reference [2] , which have been approved by the N RC.
- 2. The neutron fluence is calculated in accordance with NRC Regulatory Guide 1 . 1 90 (RG 1 . 1 90) [4], using the RAMA computer code, as documented in Reference [5].
- 3. The adjusted reference temperature (ART) values for the limiting beltl ine materials are calculated in accordance with NRC Regulatory Guide 1 .99, Revision 2 (RG 1 .99) [6], as documented in Reference [7] .
- 4. The pressure and temperature limits were calculated in accordance with Reference [ I ],
"Pressure - Temperature Limits Report Methodology for Boiling Water Reactors " June 20 1 3, as documented in Reference [8] .
- 5. This revision of the pressure and temperature limits is to incorporate the following changes:
- Initial issue of PTLR.
Changes to the curves, l imits, or parameters within this PTLR, based upon new irradiation fluence data of the RPY, or other plant design assumptions in the Updated F inal Safety Analysis Report (UFSAR), can be made pursuant to 1 0 CFR 50.59, provided the above methodologies are uti l ized. The revised PTLR shal l be submitted to the NRC upon issuance.
Changes to the curves, limits, or parameters within this PTLR, based upon new surveillance capsule data of the RPY or other plant design assumption modifications in the U FSAR, cannot
Hatch Unit 2 PTLR Revision 0 Page 6 of 40 be made without prior NRC approval . Such analysis and revisions shall be submitted to the NRC for review prior to incorporation into the PTLR.
4.0 Operating Limits The pressure-temperature (P-T) curves included in this report represent steam dome pressure versus minimum vessel metal temperature and incorporate the appropriate non-beltl ine l imits and irradiation embrittlement effects in the beltl ine region.
The operating l imits for pressure and temperature are required for three categories of operation:
(a) hydrostatic pressure tests and leak tests, referred to as Curve A; (b) core not critical operation, refe rred to as Curve 8; and (c) core critical operation, referred to as Curve C.
Complete P-T curves were developed for 3 7 EFPY and 50. 1 EFPY for HNP-2 as documented in Reference [8]. The HNP-2 P-T curves for 37 EFPY are provided in Figures I through 3, and a tabulation of the overall composite curves (by region) is included in Tables I through 3 . The HN P-2 P-T curves for 50. 1 EFPY are provided in F igures 4 through 6, and a tabulation of the overal l composite curves (by region) is included in Tables 4 through 6. The adjusted reference temperature (ART) values for the HNP-2 vessel beltline materials are shown in Table 7 for 37 EFPY and Table 8 for 50. 1 EFPY, taken from Reference [7] . The resulting P-T curves are based on the geometry, design and materials information for the HNP-2 vessel with the fol lowing conditions:
- Heat-up/Cool-down {ate limit during Hydrostatic Class I Leak Testing (Figures I and 4 :
1 Curve A): 25 .F/hour [8].
- Normal Operating Heat-up/Cool-down rate limit (Figures 2 and 5 : Curve 8 - non 2
nuclear heating, and Figures 3 and 6: Curve C - nuclear heating): I oo*F/hour [8].

- Minimum bolt-up temperature limit 90"F [8].
To address the NRC condition regarding lowest service temperature in Reference [ 1 ], the minimum temperature is set to 90 °F, which is equal to the RTN DT.max + 60 °F, for all curves.
This value is consistent with the previous minimum temperature limits developed in [9] and the minimum bolt-up temperature specified in [ I 0] .
The composite P-T curves are extended below 0 psig to - 1 4.7 psig based on the evaluation documented in Reference [ I I ], which demonstrates that the P-T curves are applicable to negative gauge pressures. S ince the P-T curve calculation methods used do not specifical ly apply to negative values of pressure, the tabulated results start at 0 psig. However, the minimum RPV pressure is - 1 4.7 psi g.
5.0 Discussion The adjusted reference temperature (ART) of the limiting beltline material is used to adjust beltline P-T curves to account for irradiation effects. RG 1 .99 [6] provides the methods for determining the ART. The RG 1 .99 methods for determining the l imiting material and adjusting the P-T curves using ART are discussed in this section.
The vessel beltline copper (Cu) and nickel (Ni) values were obtained from the evaluation of the HNP-2 vessel plate, weld, and forging materials [7] . The Cu and Ni values were used with Table l of RG 1 .99 [6] to determine a chemistry factor (CF) per Paragraph 1 . 1 of RG 1 .99 for welds.
The Cu and N i values were used with Table 2 of RG 1 .99 to determine a CF per Paragraph 1 . 1 of RG 1 .99 for plates and forgings. Since only one surveil lance capsule containing the appropriate plate heat has been tested no fitted chemistry factor is available.
2 The RPV 10 fluence value, associated with the limiting ART, of 1 .95 x 1 0 1 8 n/cm at 37 EFPY was developed in Reference [7] based on linear interpolation between reported fluence values for 26.6 EFPY and 50. 1 EFPY from Reference [5], which were calculated in accordance w ith RG 18 2 1 . 1 90 [4] . The RPV ID fluence value, associated with the limiting ART, of 2.60 x 1 0 n/cm at
Hatch Unit 2 PTL R Revision 0 Page 8 of 40
These fluence values apply to the l imiting beltline lower shel l plate (Heat No. C8553- l ). The fluence values for the limiting lower shell plate are based upon an attenuation factor of 0.682 for a postulated 1 /4T flaw. As a result, the I /4T fluence for 3 7 EFPY and 50. 1 EFPY for the 18 2 18 2 l imiting lower shell plate are 1 .33 x 1 0 n/cm and 1 .77 x 1 0 n/cm , respectively, for HNP-2.
The water level instrument (WLI) nozzle is located in the lower intermediate shell beltl ine plates 18 2
[8] . The RPV ID fluence value of 2.45 x 1 0 n/cm at 37 EFPY was developed in Reference [7]
based on linear interpolation between reported fl uence values for 26.6 EFPY and 50. 1 EFPY from Reference [5], which were calculated in accordance with RG 1 . 1 90 [4] . The peak RPV 1 0 18 2 fluence value o f and 3 .28 x I 0 /cm at 50. 1 EFPY was obtained from Reference [5] and was calculated in accordance with RG 1 . 1 90 [4] . These fluence values apply to the limiting lower intermediate shell plate (Heat No. C85 79-2). The fluence values for the WLI nozzle are based upon an attenuation factor of 0.724 for a postulated I /4T flaw. As a result, the I /4T fluence for 18 2 3 7 EFPY and 50. 1 EFPY for the limiting lower intermediate shell plate are 1 .77 x I 0 n/cm and 18 2 2.38 x 1 0 n/cm , respectively, for HNP-2. The recirculation inlet (N2) and outlet (N I ) nozzles do not exist in the beltline region. However, the outer edge of the recirculation inlet nozzle forging is within Y4 inch of the beltline [7]. Based on the ART evaluation in Reference [7], the N2 nozzle forging material is not limiting.
The P-T curves for the core not critical and core critical operating conditions at a given EFPY apply for both the I /4T (inside surface flaw) and 3/4T (outside surface flaw) locations. When combining pressure and thermal stresses, it is usually necessary to evaluate stresses at the 1 /4T and the 3/4T locations. This is because the thermal gradient tensile stress of interest is in the inner wal l during cool-down and is in the outer wall during heat-up. However, as a conservative simplification, the thermal gradient stresses at the 1 /4T location are assumed to be tensile for both heat-up and cool-down. This results in the approach of applying the maximum tensile stresses at the 1 /4T location. This approach is conservative because irradiation effects cause the
Hatch Unit 2 PTLR Revision 0 Page 9 of 40 allowable toughness at the I /4T to be less than that at 3/4T for a given metal temperature. This approach causes no operational difficulties, since the B WR is at steam saturation conditions during normal operation, which is well above the P-T curve limits.
For the core not critical curve (Curve B) and the core critical curve (Curve C), the P-T curves specify a coolant heat-up and cool-down temperature rate of :S I oo*F/hr for which the curves are appl icable. However, the core not critical and the core critical curves were also developed to bound Service Level A/8 RPV thermal transients. For the hydrostatic pressure and leak test curve (Curve A), a coolant heat-up and cool-down temperature rate of :S 25.F/hr must be maintained. The P-T limits and corresponding limits of either Curve A or 8 may be appl ied, if necessary, while achieving or recovering from test conditions. So, although Curve A applies during pressure testing, the limits of Curve 8 may be conservatively used during pressure testing if the pressure test heat-up/cool-down rate limits cannot be maintained.
The initial RTNoT, the chemistry (weight-percent copper and nickel) and ART at the I /4T 17 location for all RPV beltl ine materials significantly affected by tluence (i.e., tl uence > 1 0 n/cm2 for E > I MeV) are shown in Table 7 for 3 7 EFPY and Table 8 for 50. 1 EFPY [7] . The initial RTN oT values shown in Tables 7 and 8 have been previously approved for use by the NRC per Reference [ I 7] .
Per Reference [7] and in accordance with Appendix A of Reference [ I ], the HNP-2 representative weld and plate surveillance materials data were reviewed from the Boiling Water Reactor Vessel and Internals Project (BWRVIP) Integrated Surveillance Program (ISP) [ 1 2] .
The HNP- 2 representative plate and weld materials C8554 and 5 1 9 1 2, respectively, are contained in the HNP-2 survei llance capsules [7] . B WRVIP- 1 3 5 [ 1 2] contains surveillance capsule test results for the Hatch Unit 2 representative plate and weld materials. The representative plate heat does not match the target plate heat; however, it does match the heat for
Hatch Unit 2 PTLR Revision 0 Page 1 0 of 40 plate material used in other beltline plates. S ince only one surveillance capsule containing this plate heat has been tested no fitted chemistry factor is available; therefore, the CF calculated using the RG 1 .99 [6] tables is used. The representative weld material heat does not match any weld material heats used in the Hatch Unit 2 beltl ine; therefore, the CF calculated using the RG 1 .99 tables is used.
The ANSYS finite element computer program was used to develop the stress distributions through the feedwater (FW) nozzle [ 1 3] . These stress distributions were used in the determination of the stress intensity factors for the FW nozzle [ 1 4] . At the time that each of the analyses above was performed, the ANS YS program was controlled under the vendor's I 0 CFR 50 Appendix B [ 1 5] Qual ity Assurance Program for nuclear quality-related work.
The plant-specific HN P-2 FW nozzle analysis was performed to determine stress intensity factors due to through-wall pressure stress distributions and thermal stress distributions due to bounding thermal transients [ 1 4] . Pressure and thermal stress distributions were taken from Reference [ 1 3]. Detai led information regarding the analysis can be found in References [ 1 3, 1 4] .
The following summarizes the development o f the thermal and pressure stress intensity factors for the F W nozzle [ 1 4] :
- With respect to thermal stresses, the thermal shock which represents the maximum thermal shock for the FW nozzle during normal and upset operating conditions was analyzed [ 1 3] . The thermal stress distribution, corresponding to the limiting time point presented in [ 1 3] , along a linear path through the nozzle corner is used [ 1 4] . Leakage is considered in the heat transfer calculations [ 1 3] . The thermal down shock of 450°F produces the h ighest tensile stresses at the I /4T location. The BIE/IF methodology presented in the S l P-T Curve L TR [ I ] is used to calculate the thermal stress intensity, K1T, due to the thermal shock by fitting a third order polynomial equation to the path stress distribution for the thermal shock load case [ 1 4] . Because operation is along the
Hatch Unit 2 PTLR Revision 0 Page I I of 40 saturation curve, the resulting K1T can be linearly scaled to determine the K1T to reflect the worst-case step change due to the avai lable temperature difference. It is recognized that at low temperatures, the available temperature difference is insignificant and could potentially result in a near zero stress distribution. Therefore, a minimum K1T is calculated based on the thermal ramp of I 00°F/hr, which is associated with the shutdown transient [ 1 4] . The resulting combination of the thermal down shock and thermal ramp KIT values represent the bounding thermal stress intensity factors in the FW nozzle associated with the P-T curves for the non-beltline region.
- Boundary conditions and heat transfer coefficients were developed based on testing as described in Appendix A of Reference [ I 3a] .
- With respect to pressure stresses, a unit pressure of I 000 psig was applied to the internal surfaces of the finite element model (FEM) [ 1 3] . The pressure stress distribution was taken along the same path as the thermal stress distribution. Recognizing that the Reference [ I 3] evaluation was performed using a 2-D axi-symmetric finite element model FEM and that it is known that the stress intensification caused by the nozzle geometry is under predicted in a 2-D axi-symmetric representation of the nozzle, a correction factor was applied to the stresses obtained from the 2-D axi-symmetric FEM as described in Reference [ 1 4] . The B I E/IF methodology presented in the SI P-T Curve L TR [ I ] is used to calculate the pressure stress intensity factor, K1p, by fitting a third order polynomial equation to the path stress distribution for the pressure load case. The resulting K1p can be linearly scaled to determine the K1p for various RPV internal pressures.
- Material properties were taken from the H NP-2 code of construction [ I 6]. Use of temperature dependent material properties is expected to have minimal impact on the results of the analysis.

Hatch Unit 2 PTLR Revision 0 Page 40 of 40 Appe n dix A HATCH UNIT 2 REACTOR VESSEL MATERIALS SURVEILLANCE PROGRAM I n accordance with 1 0 CFR 50, Appendix H, Reactor Vessel Material Surveil lance Program Requirements, one survei llance capsule was removed from the Hatch Nuclear Plant Unit 2 (HNP-2) reactor vessel in 1 989 fol lowing cycle 8 [ 1 8] . The surveil lance capsule contained flux wires for neutron tluence measurement, Charpy V-Notch impact test specimens and uniaxial tensile test specimens fabricated using materials from the vessel materials within the core beltl ine region [ 1 8] .
Southern Nuclear Operating Company comm itted to use the I S P i n place o f its existing survei l lance programs in the amendments issued by the N RC regarding the implementation of the Boiling Water Reactor Vessel and Internals Project Reactor Pressure Vessel Integrated Survei llance Program, dated March I 0, 2003 [ 1 9] . The BWRVIP I S P meets the requirements of 1 0 CFR 50, Appendix H, for Integrated Survei llance Programs, and has been approved by NRC for the period of extended operation [20] . HNP-2 continues to be a host plant under the ISP
[ 1 2] . Two more HNP-2 capsule are scheduled to be removed and tested under the I S P in approximately 20 1 7 and 2027.
