SUMMARY
DESCRIPTION Pursuant to 10 CFR 50.90, Dominion Nuclear Connecticut, Inc. (DNC) requests an amendment to Facility Operating Licenses IDPR-65 and NPF-49 for Millstone Power Station Unit 2 (MPS2) and Unit 3 (MPS3), respectively. The proposed amendment will modify MPS2 and MPS3 Technical Specification (TS) 4.0.5 to reference the American Society of Mechanical Engineers (ASME) Code for Operation and Maintenance of Nuclear Power Plants (OM Code) instead of Section XI of the ASME Boiler and Pressure Vessel (B&PV) Code. Additionally the redundant requirement in TS 4.0.5 to maintain an IS1 program is being proposed for removal based on duplicate regulatory requirements in 10 CFR 50.55a.
The proposed changes are consistent with implementation of the MPS2 fourth and MPS3 third ten year lnservice Testing (IST) program in accordance with the requirements of 10 CFR 50.55a(f), "lnservice testing requirements." The MPS2 fourth ten year IST interval and MPS3 third ten year IST interval begin on April 1, 2008.
The proposed amendment is based on NRC-approved Technical Specification Task Force (TSTF) Traveler TSTF-479-A, Revision 0, "Changes to Reflect Revision of 10 CFR 50.55a11' and TSTF-497-A, Revision 0, "Limit lnservice Testing Program Application to Frequencies of 2 Years or Less."
To ensure MPS2 and MPS3 TS are in compliance with ASME code by the start of the next IST interval, DNC requests approval of the proposed amendment by February 1, 2008, with the amendment being implemented within 60 days of issuance.
2.0 DETAILED DESCRIPTION The MPS2 and MPS3 Technical Specification (TS) 4.0.5 establishes the requirement that inservice inspection (ISI) of ASME Code Class 1, 2, and 3 components and inservice testing (IST) of ASME Code Class 1, 2, and 3 pumps and valves are performed in accordance with a periodically updated version of Section XI of the ASME B&PV Code and Addenda as required by 10 CFR 50.55a. TS 4.0.5 includes a clarification of the frequencies for performing the inservice inspection and testing activities required by Section XI of the ASME B&PV Code . This clarification is provided to ensure consistency in surveillance intervals throughout the TS. Aside from minor punctuation differences, the wording of MPS2 and MPS3 TS 4.0.5 is identical.
TSTF-479-A (Reference 6.1) was developed to indicate that the IST program include testing frequencies applicable to the ASME OM Code which replaces the ASME B&PV Code as it relates to IST of pumps and valves. TSTF-479-A was approved as an administrative change by the NRC (Reference! 6.2) and incorporated into Revision 3.1 of the improved standard Technical Specifications for Combustion Engineering (NUREG-1432) and Westinghouse (NUREG-1431) plan~ts.
Serial No. 07-0207 Docket Nos. 50-336, 50-423 ASME OM Code Reference Attachment 1 Page 3 of 9 TSTF-497-A (Reference 6.3) was developed to provide an additional clarification that limits the provisions of surveillance requirement 3.0.2 (which permits a 25% extension of the interval specified in the frequency) to those IST frequencies specified as 2 years or less. TSTF-497-A was approved in an NF!C safety evaluation (Reference 6.4) but is not yet incorporated into the improved standard TS. Surveillance requirement 3.0.2 is a reference to the industry standard provision in NUREG-1431 and NUREG-1432. MPS2 and MPS3 contain a similar provision in T'S 4.0.2 which states "Each Surveillance Requirement shall be performed within the specified time interval with a maximum allowable extension not to exceed 25% of the surveillance time interval."
The MPS2 and MPS3 proposed changes are in accordance with TSTF-479-A and TSTF-497-A except for the administrative differences of TS location (MPS Section 3.014.0 versus Administrative Section 5.0 in the NUREGs) and format.
To ensure consistency between the MPS2 and MPS3 proposed changes and those of the TSTFs discussed above, DNC is also proposing to remove the inservice inspection (ISI) program requirement and corresponding ASME B&PV Code referencing from TS 4.0.5. The NRC conducted a review of the Administrative Section 5.0 of the standard TS and concluded that provisions for the IS1 program (and other programs) could be relocated to other licensee documents provided changes to the provisions are adequately controlled by other regulatory requirements (Reference 6.5). In its review the NRC also provided the justification that TS should not duplicate other regulatory requirements.
Corresponding TS Bases changes will be made in accordance with the respective unit's TS Bases Control Program and have not been included for information in this submittal due to the administrative nature of the changes.
3.0 TECHNICAL EVALUATION
3.1 Background The background for the changes being proposed by this license amendment request is the same as the Background sections associated with TSTF-479-A and TSTF-497-A.
One exception is that the application of provision 3.0.2, as it relates to IST frequencies in the improved standard TS, corresponds to ithe provision 4.0.2 in MPS2 and MPS3 TS that is quoted in the previous section. This difference is not considered to be technically significant.
Serial No. 07-0207 Docket Nos. 50-336, 50-423 ASME OM Code Reference Attachment 1 Page 4 of 9 3.2 Technical Analvsis 3.2.1 ASME OM Code Reference Update The technical analysis for the MPS2 and IMPS3 proposed changes relating to IST activities are as specified in the Technical Analysis Sections of TSTF-479-A and TSTF-497-A. One exception is the application of provision 3.0.2 as it relates to IST frequencies in the improved standard TS corresponds to the provision 4.0.2 in MPS2 and MPS3 TS that is quoted in the previous section. This difference is not considered to be technically significant.
3.2.2 Removal of Referencing to IS1in TS 4.0.5 During review of MPS2 and MPS3 TS 4.0.5 for implementation of TSTF-479-A and TSTF-497-A, it was determined that the surveillance frequencies table headings in TS 4.0.5 should be clarified to indicate that the !;urveillance frequencies listed in the table are applicable to IST only. For that reason, reference to IS1 activities is removed from the surveillance frequencies table headings. Likewise 4.0.5 c. and 4.0.5.d, which refer to the frequencies listed in the table, also propose removal of reference to ISI.
MPS2 and MPS3 are required by NRC regulation 10 CFR 50.55a(g)(4) to meet IS1 requirements for ASME Code Class 1, 2, and 3 components set forth in Section XI of editions of the ASME B&PV Code and Addenda incorporated by reference in 10 CFR 50.55a(b). MPS2 and MPS3 maintain (and make necessary changes to) their respective IS1 programs in accordance with approved station manuals and procedures as required by 10 CFR 50.55a(g). The current TS requirement in 4.0.5.a duplicates this regulation for IS1 requirements and its deletion will not reduce MPS's commitment to the IS1 program. Removal of IS1 will not relieve hAPS of its responsibility to seek relief from Code requirements when they are impractical1 nor will it eliminate any IS1 activities not covered by 10 CFR 50.55a. Also, the current revisions (Rev. 3.1) of NUREG-1431 and NUREG-1432 do not contain a requirement to maintain an IS1 program in accordance with 10 CFR 50.55a. Based on this discussion, removal of the IS1 program from the MPS2 and MPS3 TS is determined to be an administrative change as these requirements are specified separately within the NRC's regulations.
The table below lists the surveillance requirements (SRs) that currently reference Technical Specification (TS) 4.0.5. No other referencing to TS 4.0.5 exists in the MPS2 or MPS3 TS. The context of each reference was reviewed and, with the exception of the snubbers TS, determined to be applicable to inservice testing requirements and not inservice inspection requirements. For the snubbers TS (MPS2 TS 4.7.8 and MPS3 TS 4.7.10), the reference to TS 4.0.5 will be cha~ngedto the Inservice Inspection Program.
Deleting inservice inspection from the language in 4.0.5 will not impact any other TS.

4.0 REGULATORY EVALUATION
4.1 Applicable Reaulatorv Reauirementslcriteria NRC regulation 10 CFR 50.55a defines the requirements for applying industry codes to each licensed nuclear powered facility. 10 CFR 50.55a(f)(4)(i) requires programs to perform inservice testing of certain ASME Code Class 1, 2, and 3 pumps and valves during the initial 120-month interval. The regulations require that programs be developed utilizing the latest edition and addenda incorporated into paragraph (b) of 10 CFR 50.55a on the date 12 months before the date of issuance of the operating license. Likewise, 10 CFR 50.55a(f)(4)(ii) requires licensees to comply with the requirements of the latest edition and addenda of the ASME OM code incorporated by reference in 10 CFR 50.55a(b) 12 months before the start of successive 120-month intervals. NRC regulation 10 CFR 50.55a(g)(4)(i) and (ii) provide similar requirements for the inservice inspection of ASME Code Class 1, 2, and 3 components.
4.2 Precedent The NRC staff recently approved license amendments for Kewaunee Power Station on December 14, 2006 (TAC No. MD3055), Watts Bar Nuclear Plant Unit 1 on December 18, 2006 (TAC No. MD2380) and for Point Beach Nuclear Plant on June 8, 2006 (TAC No. MC8929). These precedents incorporated updating to the ASME OM Code and clarification of IST frequencies. The staff approved a license amendment for Surry
Serial No. 07-0207 Docket Nos. 50-336, 50-423 ASME OM Code Reference Attachment IPage 7 of 9 Power Station on July 15, 2005 (TAC Ncrs. MC5034 and MC5035) that included removing the IS1 program from TS 4.0.5. The Surry license amendment also relocated IST requirements and replaced all referencing to 4.0.5 throughout the TS with that of the IST program. However, MPS has limited the scope of this proposed change to removal of ISI, due to the impact on other specifications and the need for NRC approval of the ASME Code update to support the start of the! intervals.
4.3 Significant Hazards Consideration The proposed change modifies the Millstone Power Station Unit 2 (MPS2) and Unit 3 (MPS3) Technical Specifications Surveillance Requirement 4.0.5 to replace the reference to Section XI of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code with a refere~nceto ASME Code for Operation and Maintenance of Nuclear Power Plants (ASME OM Code) to be consistent with the requirements of 10 CFR 50.55a(f)(4). The proposed changes also clarify applicable inservice testing (IST) frequencies of ASME Code Class 1, 2, and 3, pumps and valves.
Additionally, the proposed change removes ;a TS requirement to maintain an inservice inspection (ISI) program for ASME Code Class 1, 2, and 3 components in deference to the regulatory requirements in 10 CFR 50.55a(g) which duplicates the MPS2 and MPS3 TS requirement. Dominion Nuclear Connecticut, Inc. (DNC) has evaluated whether or not a significant hazards consideration is involved with the proposed changes by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change does not modify any plant equipment and does not impact any failure modes that could lead to an accident. Additionally, the proposed change has no effect on the consequence of any analyzed accident since the change does not affect the function of any equipment credited for accident mitigation. The proposed change incorporates revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves. Removing from TS the duplicate requirement in the regulations to maintain an IS1 program in accordance with ASME codes and standards does not impact any accident initiators or analyzed events or mitigation of events. No reduction in previous commitments to 10 CFR 50.55a(g) are being proposed by this change.
Based on the discussion above, the proposed change does not involve a significant increase in the probability or consequences 01 an accident previously evaluated.
Serial No. 07-0207 Docket Nos. 50-336, 50-423 ASME OM Code Reference Attachment 1 Page 8 of 9
- 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed change does not involve a modification to the physical configuration of the plant (i.e., no new equipment will be! installed) or adversely affect methods governing normal plant operation. The proposed change will not impose any new or different requirements or introduce a new accident initiator, accident precursor, or malfunction mechanism. The proposed chalnge does not alter existing test criteria or frequencies. Additionally, there is no change in the types or increases in the amounts of any effluent that may be released off-site and there is no increase in individual or cumulative occupational exposure. The proposed changes incorporate revisions to the ASME Code that result in a net improvement in the measures for testing pumps and valves. Removal of the duplicate TS requirement to maintain an IS1 program will not alter the commitment to the current IS1 program requirements in 10 CFR 50.55a or any other TS requirements related to inservice inspection.
Based on the discussion above, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No.
The proposed change revises TS 4.0.5 regarding inservice testing of ASME Code Class 1, 2, and 3 pumps and valves, for consistency with the requirements of 10 CFR 50.55a(f)(4). The proposed change incorpolrates an administrative clarification to the frequencies for IST and incorporates revisioris to the ASME Code that result in a net improvement in the measures for testing pumps and valves. No setpoints or safety limit settings are being revised. The safety function of the affected pumps and valves will continue to be confirmed through inspection and testing. Removal of the IS1 program requirement from TS 4.0.5 does not remove the requirement from regulations, and therefore, will not diminish the current station approved programs and procedures that implement the regulatory criteria of 10 CFR 50.55a(g) to maintain an acceptable IS1 program in accordance with the ASME Code.
Based on the discussion above, the proposled change does not involve a significant reduction in a margin of safety.
