RAI 4.2.1-1 The Charpy Upper-Shelf Energy (USE) and Pressurized Thermal Shock analyses utilize the neutron fluence at 48 effective full power years (EFPY) to represent the neutron fluence for the reactor vessels at the end of the period of extended operation.
A) What were the EFPY achieved for each unit prior to the last refueling outage? What capacity factors and neutron flux were assumed for each unit from the last refueling outage to the end of the period of extended operation to result in 48 EFPY at the end of the period of extended operation?
Explain why these capacity factors and neutron flux values are applicable for determining the neutron fluence for the reactor vessels at the end of the period of extended operation.
B) How will future capacity factors, neutron flux and neutron fluence values be monitored to ensure 48 EFPY values bound the actual conditions of the reactor vessels at the end of the period of extended operation?
Response for RAI 4.2.1-1 A response to the RAI was provided in Reference
- 6. Per telecom on December 4, 2007 (ML073450327) the following clarification is provided: For IP2, the calculated fluence received by the vessel at 21.8 EFPY (end of cycle 17) is 9.190E+18 n/cm 2.The expected neutron flux corresponding to the licensed reactor power rating for Cycle 18 through the period of extended operation is as follows.

At the end of Cycle 14, Indian Point 3 had operated for 19.3 EFPY with a calculated fluence of 6.86E+18 n/cm 2.Using WCAP-16251 Table 6-2, the expected neutron flux corresponding to the licensed reactor power rating for Cycle 15 through the period of extended operation is as follows.45 degree vessel location Cycle flux [n/cm 2-s]15 9.63E+9 16 9.78E+9 Future cycles to 48 EFPY 9.78E+9 RAI 4.2.2-1 Table 4.2-2 in the LRA indicates that the percentage drop in Charpy USE for plate B2803-3 is 21.3 percent at 48 EFPY. The percentage drop in Charpy USE for plate B2803-3 was determined using its surveillance data, in accordance with Position 2.2 of Regulatory Guide (RG) 1.99, Revision 2, "Radiation Embrittlement of Reactor Vessel Materials." Provide the analysis that was used to determine the percentage drop in Charpy USE for plate B2803-3, include all surveillance data (unirradiated and irradiated Charpy USE and surveillance capsule neutron fluence) and references for the surveillance data.Response for RAI 4.2.2-1 A response to the RAI was provided in Reference

Refer to the attached LRA revision for changes to LRA Table 4.2-2.With the additional surveillance data, the chemistry factor for lower shell plate B2803-3 for 48 EFPY shown in LRA Tables 4.2-4 and 4.2-6 requires revision based on Table D-1 of WCAP-16251. Refer to the LRA revision attachment for changes to these tables.
NL-08-014 Attachment 1 Docket Nos. 50-247 & 50-286 Page 4 of 21 RAI 4.2.5-1 A) Table 4.2-3 in the LRA indicates that the ARTNDT value caused by irradiation for the intermediate shell axial welds and the lower shell axial welds in IP2 were determined using surveillance data reported in WCAP-15629, Revision 1, "Indian Point Unit 2 Heatup and Cooldown Limit Curves for Normal Operation and PTLR Support Documentation." This WCAP has surveillance data from IP2, IP3, and H.B. Robinson, Unit 2. The IP2 fluences were calculated using approved methodologies (WCAP-15557-RO, "Qualification of the Westinghouse Pressure Vessel Neutron Fluence Evaluation Methodology," and WCAP-14040-NP-A, Revision 2, "Methodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves") that are based on RG 1.190, "Calculational and Dosimetry Methods for Determining Pressure Vessel Neutron Fluence," March 2001, (This RG requires the use of ENDF/BVI for determining neutron cross-sections which are included in the BUGLE-96 cross-section file). In addition, there is excellent agreement between calculated and corresponding measured values. The IP3 capsule analyses also used approved methods and cross sections, thus, they are acceptable.
The H.B. Robinson calculations are reported in WCAP-14044, 'Westinghouse Surveillance Capsule Neutron Fluence Re-evaluation," that was issued in 1994 (before the issuance of RG 1.190 and the availability of BUGLE-96 and ENDF/BVI).
WCAP-1 5629, Revision 1 indicates that 15%was added to the values reported in WCAP-14044.
Explain why 15% was added to the values reported in WCAP-14044.
Provide neutron fluence values derived using a methodology that adheres to the guidance in RG 1.190. If the revised analysis results in a change in neutron fluence for the H.B. Robinson, Unit 2 surveillance capsules, provide the ARTNDT value caused by irradiation and the RTPTS value for the intermediate shell axial welds and the lower shell'axial welds in IP2 and provide the surveillance data analysis required by 10 CFR 50.61 (c)(2)(i).
B) Table 4.2-4 in the LRA indicates that the ARTNDT caused by irradiation for the lower shell plate B2803-3 in IP3 was determined using surveillance data reported by the licensee's response to Generic Letter (GL) 92-01, "Reactor Vessel Structural Integrity." This surveillance data was reported in Attachment I to a September 4, 1998, letter from J. Knubel (New York Power Authority).
As discussed in RAI 4.2.5-1A, the surveillance data from IP3 is also reported in WCAP-15629, Revision 1. The neutron fluence values for the IP3 surveillance capsule that are reported in WCAP-15629, Revision 1 and in the September 4, 1998, letter have different values. The applicant is requested to revise the PTS analyses using neutron fluence values for the surveillance capsules that are determined using the guidance in RG 1.190 and to provide the surveillance data analysis required by 10 CFR 50.61 (c)(2)(1).
NL-08-014 Attachment 1 Docket Nos. 50-247 & 50-286 Page 5 of 21 Response for RAI 4.2.5-1 A response to the RAI was provided in Reference
- 6. Per telecom on December 4, 2007 (ML073450327) the original response is being revised in its entirety.
The following is the revised RAI 4.2.5-1 response: Part A Response for RAI 4.2.5-1 The latest surveillance data for H. B. Robinson Unit 2 (HBR2) is shown in WCAP-15805,"Analysis of H.B. Robinson Unit 2 Capsule X", and the latest IP3 data is shown in WCAP-16251,"Analysis of Capsule X from Entergy~s Indian Point 3 Reactor Vessel Radiation Surveillance Program".
Both reports use the guidance of RG 1.190. Combining the IP2, IP3, and HBR2 surveillance data results in revised IP2 intermediate shell and lower shell axial weld chemistry factors. Refer to the attached LRA revision for changes to LRA Tables 4.2-3 and 4.2-5.An incorrect margin term was discovered in LRA Table 4.2-3 while preparing this RAI clarification.
Since intermediate shell plate B2002-2 used RG 1.99 position 2.1, the correct margin term is 17.0. Refer to the attached LRA revision for changes to LRA Tables 4.2-3 and 4.2-5.The surveillance data for IP2 intermediate shell plates B2002-1, B2002-2, and B2002-3 was updated by WCAP-15629 which resulted in changes to 48 EFPY USE values for these plates.Refer to the attached LRA revision for changes to LRA Table 4.2-1.Part B Response for RAI 4.2.5-1 The IP3 48 EFPY neutron fluence values reported in LRA Table 4.2-4 are shown in Table 6-2 of WCAP 16251, "Analysis of Capsule X from Entergy's Indian Point 3 Reactor Vessel Radiation Surveillance Program" which follows the guidance of RG 1.190.RAI 4.2.5-2 10 CFR 50.61 (b)(4) indicates that each pressurized water nuclear power reactor for which the analysis required by PTS rule indicates that if there is no reasonably practicable flux reduction program to prevent the RTPTS value from exceeding the PTS screening criteria based on the neutron fluence at the expiration date of the operating license, the licensee shall submit a safety analysis to determine what, if any, modifications to equipment, systems, and operation are necessary to prevent potential failure of the reactor vessel as a result of postulated PTS events if continued operation beyond the screening criteria is allowed. The analysis must be submitted at least three years before the RTPTS value is projected to exceed the PTS screening criteria.
NL-08-014 Attachment 1 Docket Nos. 50-247 & 50-286 Page 6 of 21 Section 4.2.5 in the LRA indicates that the RTpTs value for plate 82803-3 in IP3 will exceed the PTS screening criterion.
Identify the flux reduction program initiated by the applicant to prevent the RTPTS value for plate B2803-3 in IP3 from exceeding the PTS screening criterion.
Based on the information provided in response to RAI 4.2.5-1 (B) and RAI 4.2.1-1, identify when the RTPTS value for plate B2803-3 in IP3 is projected to exceed the PTS screening criterion.
Response for RAI 4.2.5-2 A response to the RAI was provided in Reference
- 6. Per telecom on December 4, 2007 (ML073450327) the following clarification is provided: The response to RAI 4.2.5-2 is not affected by the clarified response to RAI 4.2.5-1.
NL-08-014 Attachment 1 Docket Nos. 50-247 & 50-286 Page 7 of 21 LRA Revisions Per telecom on December 4, 2007 (ML073450327) the following LRA revisions are provided: LRA Section 4.2.2, Charpy Upper-Shelf Energy, Unit 2, is revised as follows.The upper shelf energy (USE) values have been determined based on the maximum projected 48 EFPY beltline fluence shown in Section 4.2.1. The beltline region chemistry and surveillance data, including the un-irradiated CvUSE information, is from the-RVI-D2 databasc and clGarificd in WCAP-1 5629, Revision 1, WCAP-1 6251, Analysis of Capsule X from Entergy's Indian Point 3 Reactor Vessel Radiation Surveillance Program, and WCAP-15805, Analysis of H.B. Robinson Unit 2 Capsule X. The projected 48 EFPY peak beltline fluence level at the clad/base metal interface of 1.906E+19 n/cm 2 was applied to all beltline materials except axial welds where the expected peak fluence is 1.295E+1 9 n/cm 2.The resulting projected 48 EFPY CvUSE drop and resulting 1t CvUSE are shown in Table 4.2-1.One intermediate shell plate (B2002-3) and one lower shell plate (B2003-1) have projected upper shelf energy levels that fall below 50 ft-lb during the period of extended operation.
All remaining plate and weld beltline materials exceed 50 ft-lb at 48 EFPY.10 CFR Part 50, Appendix G, Section IV.A.1 requires licensees to take further corrective actions for cases where the 50 ft-lbs end-of-life USE criterion cannot be met (e.g., when the EOL USE falls below the USE value criterion specified in a previously NRC-approved EMA).As noted in Table 4.2-1, the lowest projected USE level for the IP2 beltline plate material through the period of extended operation is 474 48.3 ft-lb for intermediate shell plate B2002-3. An equivalent margins analysis performed in WCAP-1 3587, Rev. 1 demonstrated that the minimum acceptable USE for reactor vessel plate material in 4 loop plants such as IP2 is 43 ft-lbs. In the safety assessment of WCAP-13587, the NRC concluded the report demonstrated margins of safety equivalent to those of the ASME code for beltline plate and forging materials.
The IP2 USE values are therefore acceptable since the IP2 lowest projected USE level for the IP2 beltline plate material through the period of extended operation of 474 48.3 ft-lb for intermediate shell plate B2002-3 is above the 43 ft-lbs minimum acceptable USE for 4 loop plants determined in WCAP-13587 Rev. 1. This determination is consistent with NUREG-1800, Section 4.2.2.1.1.2, and with the NRC Safety Evaluation Report of acceptable USE for H. B Robinson Unit 2 as documented in NUREG-1785. The TLAA for USE is projected through the period of extended operation in accordance with 1 OCFR54.21 (c)(1)(ii).
LRA Section 4.2.2, Charpy Upper Shelf Energy, Unit 3, is revised as follows.The IPEC Unit 3 upper shelf energy values have been determined based on the maximum projected 48 EFPY beltline fluence and the beltline region chemistry and surveillance data including the un-irradiated CvUSE information as summarized in the RVQD2 databasc WCAP-1 6251, Analysis of Capsule X from Enterqy's Indian Point 3 Reactor Vessel Radiation Surveillance Program. The projected 48 EFPY peak beltline fluence level at the clad/base metal interface of 1.560E+1 9 n/cm 2 was conservatively applied to all beltline materials.
The 48 EFPY 'At fluence level of 9.298E+1 8 n/cm 2 was calculated in accordance with Regulatory Guide 1.99, Equation (3) based on a vessel thickness of 8.625". The resulting projected 48 EFPY CvUSE drop and resulting 1/t CvUSE are displayed in Table 4.2-2. All plate and weld beltline materials exceed 50 ft-lb at 48 EFPY aid aR NL-08-014 Attachment 1 Docket Nos. 50-247 & 50-286 Page 8 of 21...utalent m.argins as not rc.uircd with the exception of the lower shell plate B2803-3 with a predicted USE of 49.8 ft-lbs. As noted above for IP2, an equivalent margins analysis performed in WCAP-1 3587, Rev. 1 demonstrated that the minimum acceptable USE for reactor vessel plate material in 4 loop plants such as IP3 is 43 ft-lbs. Therefore, the IP3 lower shell plate B2803-3 USE value of 49.8 ft-lbs is acceptable.
This determination is consistent with NUREG-1 800, Section 4.2.2.1.1.2, and with the NRC Safety Evaluation Report of acceptable USE for H. B Robinson Unit 2 as documented in NUREG-1785.
The TLAA for USE is projected through the period of extended operation in accordance with 1 OCFR54.21 (c)(1)(ii)
LRA Section 4.2.5, Pressurized Thermal Shock, Unit 3, first paragraph is revised as follows.The projected 48 EFPY peak beltline fluence level at the clad/base metal interface of 1.560E+19 n/cm 2 was applied to all beltline materials.
The resulting projected 48 EFPY RTPTs are shown in Table 4.2-4. All projected RTPTS values are within the established screening criteria for 48 EFPY with the exception of plate B2803-3, which exceeds the screening criterion by " 9._5 F. Values of RTNDT for the IP3 beltline materials at 1/4 T and 34 T are summarized in Table 4.2-6.

In the safety assessment of WCAP-1 3587, the NRC concluded the report demonstrated margins of safety equivalent to those of the ASME code for beltline plate and forging materials.
The USE values are therefore acceptable since the lowest projected USE level for the beltline plate material through the period of extended operation of 47448.3 ft-lb for intermediate shell plate B2002-3 is above the 43 ft-lbs minimum acceptable USE for four-loop plants determined in WCAP-1 3587 Rev. 1.LRA Section A.3.2.1.3, Charpy Upper-Shelf Energy, is revised as follows.The predictions for percent drop in CvUSE at 48 EFPY are based on chemistry data, unirradiated CvUSE data, and 1/4 T fluence values. The projected 48 EFPY peak beltline fluence level was conservatively applied to all beltline materials.

The CvUSE for all remaining plate and weld beltline materials meets the acceptable value of greater than 50 ft-lb at 48 EFPY.An equivalent margins analysis performed in WCAP-1 3587, Rev. 1, demonstrated that the minimum acceptable USE for reactor vessel plate material in four-loop plants is 43 ftlbs. In the safety assessment of WCAP-13587, the NRC concluded the report demonstrated margins of safety equivalent to those of the ASME code for beltline plate and forging materials.
The USE value is therefore acceptable since the proiected USE level through the period of extended operation of 49.8 ft-lb for lower shell plate B2003-3 is above the 43 ft-lbs minimum acceptable USE for four-loop plants determined in WCAP-1 3587 Rev. 1.
