SUBJECT:

PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNITS 1 AND 2 - ISSUANCE OF AMENDMENTS RE: (TAC NOS. MD5544 AND MD5545)

Dear Mr. Wadley:

The Commission has issued the enclosed Amendment No. 181 to Facility Operating License No. DPR-42 and Amendment No. 171 to Facility Operating License No. DPR-60 for the Prairie Island Nuclear Generating Plant (PINGP), Units 1 and 2, respectively. The amendments consist of changes to the Technical Specifications (TSs) in response to your application dated May 10, 2007.

The requested changes are a partial adoption of Technical Specification Task Force (TSTF-491), Revision 2, Removal of Main Steam and Feedwater Valve Isolation Times which was proposed by the TSTF by letter on May 18, 2006. The proposed changes revise TS 3.7.2 Main Steam Valves Closure Times by relocating the isolation valve closure times to a licensee-controlled document identified as a Bases reference. The proposed amendments deviate from TSTF-491 in that the current PINGP TS (3.7.3) and associated surveillance requirements for the main feedwater isolation valves do not include valve closure times, and thus the changes to TS 3.7.3 provided for in TSTF-491 are not applicable to the PINGP TSs and are not adopted.

A copy of our related safety evaluation is also enclosed. The Notice of Issuance will be included in the Commission's biweekly Federal Register notice.

Sincerely,

/RA/

1.0 INTRODUCTION

By letter dated May 10, 2007, (Agencywide Document and Management System (ADAMS)

Accession No. ML071300622), Nuclear Management Company, LLC (NMC), (the licensee),

proposed changes to the technical specifications (TS) for Prairie Island Nuclear Generating Plant (PINGP) Units 1 and 2. The requested changes are a partial adoption of Technical Specification Task Force (TSTF) -491, Revision 2, Removal of Main Steam and Feedwater Valve Isolation Times which was proposed by the TSTF by letter on May 18, 2006. The proposed changes revise TS 3.7.2 Main Steam Valves Closure Times by relocating the isolation valve closure times to a licensee-controlled document identified as a Bases reference.

The proposed amendments deviate from TSTF-491 in that the current PINGP TS (3.7.3) and associated surveillance requirements for the main feedwater isolation valves do not include valve closure times, and thus the changes to TS 3.7.3 provided for in TSTF-491 are not applicable to the PINGP TSs and are not adopted. TSTF-491, Revision 2, was announced for availability in the Federal Register on December 29, 2006, as part of the consolidated line item improvement process (CLIIP).

2.0 REGULATORY EVALUATION

Section 182(a) of the Atomic Energy Act (the Act) requires applicants for nuclear power plant operating licenses to include TS as part of the license. The TS ensure the operational capability of structures, systems and components that are required to protect the health and safety of the public. The Commissions regulatory requirements related to the content of the TS are contained in Title 10 of the Code of Federal Regulations (10 CFR) Section 50.36. That regulation requires that the TS include items in the following specific categories: (1) safety limits, limiting safety systems settings, and limiting control settings (50.36(c)(1)); (2) limiting conditions for operation (50.36(c)(2)); (3) surveillance requirements (50.36(c)(3)); (4) design features (50.36(c)(4)); and (5) administrative controls (50.36(c)(5)).

In general, there are two classes of changes to TS: (1) Changes needed to reflect modifications to the design basis (TS are derived from the design basis), and (2) voluntary changes to take advantage of the evolution in policy and guidance as to the required content and preferred format of TS over time. This amendment deals with the second class of changes. In determining the acceptability of revising Standard Technical Specifications (STS) 3.7.2, the

Nuclear Regulatory Commission (NRC) staff used the accumulation of generically-approved guidance in NUREG-1431, Revision 3, Standard Technical Specifications, Westinghouse Plants, dated June 2004. Licensees may revise the TS to adopt current improved STS format and content provided that plant-specific review supports a finding of continued adequate safety because: (1) the change is editorial, administrative or provides clarification (i.e., no requirements are materially altered), (2) the change is more restrictive than the licensees current requirement, or (3) the change is less restrictive than the licensees current requirement, but nonetheless still affords adequate assurance of safety when judged against current regulatory standards.

The Commissions regulatory requirements regarding codes and standards are specified in 10 CFR 50.55a, which incorporates portions of industry codes and standards, such as the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, into the regulations and the associated requirements for Inservice Testing (IST). Much of the information associated with a licensees implementation of the testing and surveillance requirements in 10 CFR 50.55a, is contained in their IST Program. The 10 CFR 50.59 criteria provide adequate assurance that prior staff review and approval will be requested by the licensee for changes to the Bases or Licensee-Controlled Document (LCD) requirements with the potential to affect the safe operation of the plant.

The detailed application of this general framework, and additional specialized guidance, are discussed in Section 3.0 in the context of specific proposed changes. Nomenclature specific to the Westinghouse Plants is used in the following technical evaluation.

3.0 TECHNICAL EVALUATION

The NRC staff has reviewed the justification for the proposed TSTF as described in the September 13, 2005, submittal. The detailed evaluation below will support the conclusion that:

(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 Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

3.1 Main Steam Isolation Valves (MSIV)

One MSIV is located in each main steamline outside of the containment. Closing the MSIVs isolates each steam generator from the others and isolates the turbine, steam bypass system, and other auxiliary steam supplies from the steam generator. By isolating the steam flow from the secondary side of the steam generator, the MSIVs prevent overcooling the reactor core following a high-energy line break. By preventing core overcooling the MSIVs protect the reactor core from being damaged. TSTF-491 is proposing to relocate the required closure times for the MSIVs to the LCD, Technical Requirements Manual, that is referenced in the Bases. Changes to the LCD are subject to the 10 CFR 50.59 process. The 10 CFR 50.59 criteria provide adequate assurance that prior NRC staff review and approval will be requested by the licensee for changes to the Bases or LCD requirements with the potential to affect the safe operation of the plant. Furthermore, the MSIVs are subject to periodic testing and acceptance criteria in accordance with the IST Program. Compliance with the IST Program is required by Section 5.5.7 of the STS and 10 CFR 50.55a. The IST Program includes specific reference value baseline operating times for valves that are not subject to arbitrary changes.

The regulation at 10 CFR 50.36 requires the inclusion of the periodic testing of the MSIVs in the surveillance requirements, not the actual closure time of the valves. TSTF-491 change maintains the periodic testing requirements for MSIVs in accordance with 10 CFR 50.36. Based on the requirements of 10 CFR 50.36, 10 CFR 50.59 and IST Program, the NRC staff concludes that relocating the MSIV closure time to the LCD as referenced in the Bases is acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Minnesota State official was notified of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes the requirements with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 or change the surveillance requirements. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration and there has been no public comment on such finding (72 FR 39083). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b),

no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (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 issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
