POINT BEACH NUCLEAR PLANT TECHNICAL REQUIREMENTS MANUAL TRM 2.2 PRESSURE TEMPERATURE LIMITS REPORT Note: Applicability limits for pressure temperature limits are discussed in Section 2.0, "Operating Limits."

1.0 RCS PRESSURE AND TEMPERATURE LIMITS REPORT (PTLR)

This RCS Pressure and Temperature Limits Report (PTLR) for Point Beach Nuclear Plant Units 1 and 2 has been prepared in accordance with the requirements of Technical Specification 5.6.5.

The analytical methods used to determine the RCS pressure and temperature limits shall be those previously reviewed and approved by the NRC; specifically those described in NRC Safety Evaluations dated October 6, 2000, July 23, 2001, and October 18, 2007.

The PTLR shall be provided to the NRC upon issuance for each reactor vessel fluence period and for any revision or supplement thereto. Based upon fluence values in Westinghouse report LTR-REA-04-64 ( ~ e f 5.15), this PTLR is effective for 36.9 EFPY (approximately 201 5). (Ref 5.19)

The Technical Specifications addressed in this report are listed below:

1.I 3.4.3 Pressurerremperature (P-T) Limits 1.2 3.4.12 Low Temperature Overpressure Protection (LTOP) System 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the following subsections. Changes to these limits must be developed using the NRC approved methodologies specified in Technical Specification 5.6.5.

These limits have been determined such that applicable limits of the safety analysis are met. Items that appear in capitalized type are defined in Technical Specification 1.1, "Definitions."

EFPY values listed in this procedure are estimates based on the following past and assumed future reactor power and fuel management strategy for Unit 1 (limiting vessel):

Power operation outside of these future assumptions is acceptable. However, the effect on EFPY values would need to be evaluated.

Reactor Fuel Management Strategy Low Leakage Without Hafnium Rods (Hafnium rods inserted from 5/89 (BOC 17) to 10108) 2.1 RCS Pressure and Temperature Limits (LC0 3.4.3)

Reactor Power (MWt) 1518.5 - startup to 02/03/2003 1540.0 - 02/03/2003 to 1012008 1678.0 - 10/2008 to EOLE 2.1.1 The RCS temperature rate-of-change limits are:

a. A maximum heatup rate of 100°F in any one hour.

b. A maximum cooldown rate of 100°F in any one hour POINT BEACH TRM 2.2 -1 REV. 4 04/28/2008

POINT BEACH NUCLEAR PLANT TECHNICAL REQUIREMENTS MANUAL TRM 2.2 PRESSURE TEMPERATURE LIMITS REPORT

c. An average temperature change of 510°F per hour during inservice leak and hydrostatic testing operations.

2.1.2 The RCS P-T limits for heatup and cooldown are specified by Figures 1 and 2, respectively.

2.1.3 The minimum temperature for pressurization or bolt up, using the methodology, is 60°F, which when corrected for possible instrument uncertainties is a minimum indicated RCS temperature of 78°F (as read on the RCS cold leg meter) or 70°F using the hand-held, digital pyrometer.

2.2 Low Temperature Overpressure Protection System Enable Temperature (LC0 3.4.6, 3.4.7, 3.4.10 and 3.4.12)

The enable temperature for the Low Temperature Overpressure Protection System is 285°F (includes instrument uncertainty for RCS Tc wide range). (Ref 5.4)

I 2.3 Low Temperature Overpressure Protection System Setpoints (LC0 3.4.12)

Pressurizer Power-Operated Relief Valve Lift Setting Limits The lift setting for the pressurizer power-operated relief valves (PORVs) is 5420 psig (includes instrument uncertainty).

The following operating restrictions ensure continued operability of the LTOP system:

2.3.1 RCP Operating Restriction - No more than one RCP in operation for RCS temperature < I 80°F. (Ref 5.20 to 5.24) 2.3.2 Charging Pumps - Limit the number of operating charging pumps to two when LTOP is in service. (Ref 5.20 to 5.24) 3.0 REACTOR VESSEL MATERIAL SURVEILLANCE PROGRAM The reactor vessel material irradiation surveillance specimens shall be removed and examined to determine changes in material properties. The removal schedules for Units 1 and 2 are provided in Tables 1 and 2, respectively.

For the period of the renewed facility operating license, all capsules in the reactor vessel that are removed and tested shall meet the test procedures and reporting requirements I

of ASTM E 185-82. Any changes to the capsule withdrawal schedule, including spare capsules, shall be approved by the NRC prior to implementation. (Ref 5.16 and 5.17)

The pressure vessel surveillance program is in compliance with Appendix H to 10 CFR 50, entitled, "Reactor Vessel Radiation Surveillance Program." The material test requirements and the acceptance standard utilize the nil-ductility temperature, POINT BEACH TRM REV. 4 04/28/2008

POINT BEACH NUCLEAR PLANT TECHNICAL REQUIREMENTS MANUAL TRM 2.2 PRESSURE TEMPERATURE LIMITS REPORT

RTNDT, which is determined in accordance with ASTM E208. The empirical relationship between RTNDT and the fracture toughness of the reactor vessel steel is developed in accordance with Appendix G, "Protection Against Non-Ductile Failure," to Section XI of the ASME Boiler and Pressure Vessel Code. The surveillance capsule removal schedule meets the requirements of ASTM E l 85-82.

Surveillance specimens for the limiting materials for the PBNP reactor vessels are not included in the plant specific surveillance program. Therefore, the results of the examinations of these specimens do not meet the credibility criteria of Regulatory Guide 1.99, Revision 2, for PBNP Units 1 and 2.

4.0 SUPPLEMENTAL DATA INFORMATION The RTPTs values for the PBNP limiting beltline materials at 36.9 EFPY is:

Unit 1 - Intermediate to Lower Shell Circ Weld = 277OF; Lower Shell Axial Weld = 234OF (Ref. 5.8, Table 13)

Unit 2 - lntermediate to Lower Shell Circ Weld = 292OF; lntermediate Shell Forging = 14g°F (Ref. 5.8, Table 21)

The analytical methods used to determine the RCS pressure and temperature limits shall be those previously reviewed and approved by the NRC; specifically those described in NRC Safety Evaluations dated October 6, 2000, July 23, 2001, and October 18, 2007.

The PTLR shall be provided to the NRC upon issuance for each reactor vessel fluence period and for any revision or supplement thereto (Ref 5.19). Based upon fluence values in I Westinghouse report LTR-REA-04-64 (Ref 5.15), this PTLR is effective for 36.9 EFPY (approximately 201 5). (Ref 5.2)

I The Technical Specifications addressed in this report are listed below:

1.1 3.4.3 Pressurerremperature (P-T) Limits 1.2 3.4.1 2 Low Temperature Overpressure Protection (LTOP) System 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the following subsections. Changes to these limits must be developed using the NRC approved methodologies specified in Technical Specification 5.6.5.

These limits have been determined such that applicable limits of the safety analysis are met. Items that appear in capitalized type are defined in Technical Specification 1.I, "Definitions."

I 2.1 RCS Pressure and Temperature Limits (LC0 3.4.3) 2.1.1 The RCS temperature rate-of-change limits are:

a. A maximum heatup rate of 100°F in any one hour

b. A maximum cooldown rate of 100°F in any one hour.

c. An average temperature change of 11 0°F per hour during inservice leak and hydrostatic testing operations.

2.1.2 The RCS P-T limits for heatup and cooldown are specified by Figures 1 and 2, respectively. (Ref 5.2)

POINT BEACH TRM REV. 5 05/30/2008

POINT BEACH NUCLEAR PLANT TECHNICAL REQUIREMENTS MANUAL TRM 2.2 PRESSURE TEMPERATURE LIMITS REPORT 2.1.3 The minimum temperature for pressurization or bolt up, using the methodology, is 60°F, which when corrected for possible instrument uncertainties is a minimum indicated RCS temperature of 78°F (as read on the RCS cold leg meter) or 70°F using the hand-held, digital pyrometer.

2.2 Low Temperature Overpressure Protection Svstem Enable Temperature (LC0 3.4.6, 3.4.7, 3.4.10 and 3.4.12)

The enable temperature for the Low Temperature Overpressure Protection System is 285°F (includes instrument uncertainty for RCS T, wide range). (Ref 5.4) 2.3 Low Temperature Overpressure Protection Svstem Setpoints (LC0 3.4.12)

Pressurizer Power-Operated Relief Valve Lift Setting Limits The lift setting for the pressurizer power-operated relief valves (PORVs) is 1420 psig (includes instrument uncertainty).

The following operating restrictions ensure continued operability of the LTOP system:

2.3.1 RCP Operating Restriction - No more than one RCP in operation for RCS temperature < I 80°F. (Ref 5.20 to 5.24) 2.3.2 Charging Pumps - Limit the number of operating charging pumps to two when LTOP is in service. (Ref 5.20 to 5.24) 2.4 Criticalitv and Hvdrostatic Leak Test Limits 2.4.1 Criticality and hydrostatic leak test limits are shown on the RCS Pressure Temperature Limits for heatup, Figure 1. (Ref 5.2) 3.0 REACTOR VESSEL MATERIAL SURVEILLANCE PROGRAM The reactor vessel material irradiation surveillance specimens shall be removed and examined to determine changes in material properties. The removal schedules for Units 1 and 2 are provided in Tables 1 and 2, respectively.

For the period of the renewed facility operating license, all capsules in the reactor vessel that are removed and tested shall meet the test procedures and reporting requirements of ASTM E 185-82. Any changes to the capsule withdrawal schedule, including spare capsules, shall be approved by the NRC prior to implementation. (Ref 5.16 and 5.17)

POINT BEACH TRM REV. 5 05/30/2008

POINT BEACH NUCLEAR PLANT TECHNICAL REQUIREMENTS MANUAL TRM 2.2 PRESSURE TEMPERATURE LIMITS REPORT The pressure vessel surveillance program is in compliance with Appendix H to 10 CFR 50, entitled, "Reactor Vessel Radiation Surveillance Program." The material test requirements and the acceptance standard utilize the nil-ductility temperature,

RTNDT, which is determined in accordance with ASTM E208. The empirical relationship between RTND~

and the fracture toughness of the reactor vessel steel is developed in accordance with Appendix G, "Protection Against Non-Ductile Failure," to Section XI of the ASME Boiler and Pressure Vessel Code. The surveillance capsule removal schedule meets the requirements of ASTM E l 85-82.

Surveillance specimens for the limiting materials for the PBNP reactor vessels are not included in the plant specific surveillance program. Therefore, the results of the examinations of these specimens do not meet the credibility criteria of Regulatory Guide 1.99, Revision 2, for PBNP Units 1 and 2.

4.0 SUPPLEMENTAL DATA INFORMATION The RTPTs values for the PBNP limiting beltline materials at 36.9 EFPY is:

Unit 1 - lntermediate to Lower Shell Circ Weld = 277OF; Lower Shell Axial Weld = 234OF (Ref. 5.8, Table 13)

Unit 2 - lntermediate to Lower Shell Circ Weld = 292OF; lntermediate Shell Forging = 14g°F (Ref. 5.8, Table 21)
