PTLR for FNP Unit 1 Revision 6 Page 5 of 22 1.0 RCS Pressure Temperature Limits Report (PTLR)

This PTLR for Farley Nuclear Plant - Unit 1 has been prepared in accordance with the requirement of Technical Specification (TS) 5.6.6. Revisions to the PTLR shall be provided to the NRC after issuance.

This report affects TS 3.4.3, RCS Pressure!Temperature Limits (PfT) Limits. All TS requirements associated with low temperature overpressure protection (LTOP) are contained in TS 3 .4. 1 2, RCS Overpressure Protection Systems.

2.0 Operating Limits The limits for TS 3.4.3 are presented in the subsection which follows and were developed using the methodologies specified in TS 5.6.6. The methodologies are contained in WCAP-1 4040-A, Revision 4111* The operability requirements associated with LTOP are specified in TS LCO 3.4. 1 2 and were determined to adequately protect the RCS against brittle fracture in the event of an LTOP transient. The limitation on the number of operating reactor coolant pumps (RCPs) is necessary to assure operation consistent with the pressure corrections incorporated in the P!T limits for flow losses associated with the RCPs.

2. 1 RCS Pressure!Temperature (PfT) Limits (LCO - 3.4.3)
2. 1 . 1 The minimum boltup temperature is 60°F.

2 . 1 .2 The RCS temperature rate-of-change limits are:

a. A maximum heatup of 1 00°F in any one hour period.
b. A maximum cooldown of 1 00°F in any one hour period.
c. A maximum temperature change of less than or equal to 1 0°F in any one hour period during inservice hydrostatic and leak testing operations above the heatup and cooldown limit curves.

2.1 .3 The RCS P!T limits for heatup a n d cooldown are specified b y Figures 2 - 1 a n d 2-2, respectively.

2.2 RCP Operation Limits 2.2.1 The number of operating RCPs i s limited to one a t RCS temperatures less than 1 1 ooF with the exception that a second pump may be started for the purpose of maintaining continuous flow while taking the operating pump out of service.

2.3 LTOP System Applicability Temperature (LCO- 3 .4. 1 2) 2.3.1 The Low Temperature Overpressure Protection (LTOP) System applicability temperature is 275°F.

The Farley Nuclear Plant-Unit 1 pressure-temperature limits for the reactor vessel inlet/outlet nozzle corner region and balance of reactor coolant system ferritic components were evaluated and found to be non-limiting with respect to the reactor vessel beltline pressure-temperature limits (Figures 2-1 and 2-2 below). This technical assessment was confirmed by the NRC via Safety Evaluation Report !21> .

PTLR for FNP Unit 1 Revision 6 Page 1 3 of 22 4.0 Reactor Vessel Surveillance Data Credibility Regulatory Guide 1 .99, Revision 2181 , describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of the low-alloy steels currently used for light-water-cooled reactor vessels. Position C.2 of Regulatory Guide 1 .99, Revision 2, describes the methodology for calculating the adjusted reference temperature and Charpy upper-shelf energy of reactor vessel beltline materials using surveillance capsule data. The methods of Position C.2 can only be applied when two or more credible surveillance data sets become available from the reactor in question.

Per WCAP-88 1 0191 , the Unit 1 surveillance program was based on ASTM E 1 85-7311 01 . All six surveillance capsules (YI1 11 , U 1121 , X 1131 , W l141 , V 1151 , and Z 171) have been removed from the Farley Unit 1 reactor vessel and analyzed. In accordance with the discussion of Regulatory Guide 1 .99, Revision 2, there are five requirements that must be met for the surveillance data to be judged credible.

The credibility conclusions for the Farley Unit 1 surveillance plate and weld are described below:

The credibility evaluation of the Farley Unit 1 Lower Shell Plate 8691 9-1 surveillance material is documented in Appendix D of WCAP-1 6964-NP 171 . The credibility evaluation concluded that the surveillance data for Lower Shell Plate 8691 9-1 is non-credible.

The credibility evaluation for weld Heat # 33A277 surveillance data is documented in Appendix D of WCAP-1 7365-NP1161 . The evaluation takes into account surveillance data from Calvert Cliffs U nit 1 and Farley Unit 1 . The credibility evaluation concluded that the surveillance data for weld Heat # 33A277 is credible.

5.0 Su pp lemental Data Tables Table 5-1 contains a comparison of measured surveillance material 30 ft-lb transition temperature shifts and upper shelf energy decreases with Regulatory Guide 1 .99, Revision 2, predictions.

Table 5-2 shows the calculation of the surveillance material chemistry factors using surveillance capsule data.

Table 5-3 provides the unirradiated Farley Unit 1 reactor vessel toughness data.

Table 5-4 provides a summary of the reactor vessel fluence values at 54 EFPY.

Table 5-5 provides a summary of the ART values of the Farley U nit 1 reactor vessel materials at the 1 /4-T and 3/4-T locations for 54 EFPY.

Table 5-6 shows the calculation of the ART values at 54 EFPY for the limiting Farley Unit 1 reactor vessel material (lower shell plate 869 1 9- 1 ) .

Table 5-7 provides RTPTs values for Farley Unit 1 for 5 4 EFPY.

PTLR for FNP Unit 2 Revision 6 Page 5 of 22 1 .0 RCS Pressure Temperature Limits Report (PTLR)

This PTLR for Farley Nuclear Plant - Unit 2 has been prepared in accordance with the requirement of Technical Specification (TS) 5.6.6. Revisions to the PTLR shall be provided to the NRC after issuance.

This report affects TS 3.4.3, RCS PressurefTemperature (PfT) Limits. All TS requirements associated with low temperature overpressure protection (LTOP) are contained in TS 3.4 . 1 2, RCS Overpressure Protection Systems.

2.0 Operating Limits The limits for TS 3.4.3 are presented in the subsection which follows and were developed using the NRC-approved methodologies specified in TS 5.6.6. The methodologies are contained in WCAP-1 4040-A, Revision 4111 . The operability requirements associated with LTOP are specified in TS LCO 3.4. 1 2 and were determined to adequately protect the RCS against brittle fracture in the event of an LTOP transient. The limitation on the number of operating reactor coolant pumps (RCPs) is necessary to assure operation consistent with the pressure corrections incorporated in the PfT limits for flow losses associated with the RCPs.

2.1 RCS PressurefTemperature (PfT) Limits (LCO - 3 .4.3)

2. 1 .1 The minimum boltup temperature is 60°F.

2 . 1 .2 The RCS temperature rate-of-change limits are:

a. A maximum heatup of 1 00°F in any one hour period.
b. A maximum cooldown of 1 00°F in any one hour period.
c. A maximum temperature change of Jess than or equal to 1 ooF in any one hour period during inservice hydrostatic and leak testing operations above the heatup and cooldown limit curves.

2 . 1 .3 The RCS PfT limits for heatup and cooldown are specified by Figures 2-1 and 2-2, respectively.

2.2 RCP Operation Limits 2.2.1 The number of operating RCPs i s limited t o one a t RCS temperatures Jess than 1 1 0°F with the exception that a second pump may be started for the purpose of maintaining continuous flow while taking the operating pump out of service.

2.3 LTOP System Applicability Temperature (LCO- 3.4. 1 2) 2.3. 1 The Low Temperature Overpressure Protection (LTOP) System applicability temperature is 275°F.

The Farley Nuclear Plant - Unit 2 pressure-temperature limits for the reactor vessel inlet/outlet nozzle corner region and balance of reactor coolant system ferritic components were evaluated and found to be non-limiting with respect to the reactor vessel beltline pressure-temperature limits (Figures 2-1 and 2-2 below). This technical assessment was confirmed by the NRC via Safety Evaluation Reporti20J.

PTLR for FNP Unit 2 Revision 6 Page 1 2 of 22 3.0 Reactor Vessel Material Surveillance P rogram The reactor vessel material surveillance program is in compliance with 1 0 CFR 50, Appendix H, and is described in Section 5.4.3.6 of the Farley FSAR. Surveillance capsules are tested and the results reported in accordance with ASTM E1 85-82131.

The removal schedule is provided in Table 3-1 . Consistent with specific requirements for Farley Unit 2 associated with the granting of an exemption to Appendix H of 1 0 CFR 50 documented in NUREG-0 1 1 7 141 , Figures 2-1 and 2-2 are based on the greater, or limiting value, of the following: ( 1 ) the actual shift in reference temperature for plate 8721 2-1 as determined by impact testing, or (2) the predicted shift in reference temperature for weld seam 1 1 -923 as determined by Regulatory Guide 1 .99, Revision 2151 . The neutron transport and dosimetry evaluation methodologies used follow the guidance and meet the requirements of Regulatory Guide 1 . 1 90 , "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence"161 . Results from the reactor vessel surveillance program will be used to update Figures 2-1 and 2-2 if the results indicate that the adjusted reference temperature (ART) for the limiting beltline material exceeds the ART used to generate the PIT limits shown in Figures 2-1 and 2-2 for the specified fluence period.

PTLR for FNP Unit 2 Revision 6 Page 1 3 of 22 4.0 Reactor Vessel Surveillance Data Credibility Regulatory Guide 1 .99, Revision 2, describes general procedures acceptable to the NRC staff for calculating the effects of neutron radiation embrittlement of the low alloy steels currently used for light-water-cooled reactor vessels. Position C.2 of Regulatory Guide 1 .99, Revision 2, describes the methodology for calculating the adjusted reference temperature and Charpy upper-shelf energy of reactor vessel beltline materials using surveillance capsule data. The methods of Position C.2 can only be applied when two or more credible surveillance data sets become available from the reactor in q uestion .

Per WCAP-8956[81 , the Unit 2 surveillance program was based o n ASTM E1 85-73[91 .

All six surveillance capsules (U [101 , W [1 1 1, X [1 21 , Z [1 31 , Y [141 , and V [71) have been removed from the Farley Unit 2 reactor vessel and analyzed. In accordance with the discussion of Regulatory Guide 1 .99, Revision 2, there are five requirements that must be met for the surveillance data to be judged credible.

The credibility conclusions for the Farley Unit 2 surveillance plate and weld are described below:

The credibility evaluation of the Farley Unit 2 surveillance materials is documented in WCAP-1 691 8-NP, Revision 1 [71 . The credibility evaluation concluded that the surveillance data for Intermediate Shell Plate 872 1 2-1 is credible. The credibility evaluation concluded that the surveillance data for weld Heat # BOLA is non credible.

5.0 Supplemental Data Tables Table 5-1 contains a comparison of measured surveillance material 30 ft-lb transition temperature shifts and u pper shelf energy decreases with Regulatory Guide 1 .99, Revision 2, predictions.

Table 5-2 shows the calculation of the surveillance material chemistry factors using surveillance capsule data.

Table 5-3 provides the unirradiated Farley Unit 2 reactor vessel toughness data.

Table 5-4 provides a summary of the reactor vessel fluence values at 54 EFPY.

Table 5-5 provides a summary of the ART values of the Farley Unit 2 reactor vessel materials at the 1 /4-T and 3/4-T locations for 54 EFPY.

Table 5-6 shows the calculation of the ART values at 54 EFPY for the limiting Farley Unit 2 reactor vessel material.

Table 5-7 provides RTPTs values for Farley Unit 2 for 54 EFPY.
