-Operated by Nuclear Management Company, LLC DCTI 5 2004 L-PI-04-112 10 CFR 50.90 U S Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 Prairie Island Nuclear Generating Plant Units 1 and 2 Dockets 50-282 and 50-306 License Nos. DPR-42 and DPR-60 Application for Technical Specification Improvement to Extend the Inspection Interval for Reactor Coolant Pump Flywheels Using the Consolidated Line Item Improvement Process Pursuant to 10 CFR 50.90, the Nuclear Management Company, LLC (NMC) hereby requests an amendment to the Technical Specifications (TS) for the Prairie Island Nuclear Generating Plant (PINGP) Units I and 2.

The proposed amendment will extend the reactor coolant pump (RCP) motor flywheel examination frequency from the currently approved 10-year inspection interval, to an interval not to exceed 20 years. The changes are consistent with Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-421, "Revision to RCP Flywheel Inspection Program (WCAP-1 5666)." The availability of this TS improvement was announced in the FederalRegisteron October 22, 2003 as part of the consolidated line item improvement process (CLIIP).

Exhibit A provides a description of the proposed change and confirmation of applicability. Exhibit B provides the existing TS page marked up to show the proposed change. Exhibit C provides the revised, clean TS page.

NMC requests approval of the proposed License Amendment by September 30, 2005, with the amendment being implemented within 90 days.

In accordance with 10 CFR 50.91, NMC is notifying the State of Minnesota of this LAR by transmitting a copy of this letter and attachments to the designated State Official.

Summary of Commitments This letter contains no new commitments and no revisions to existing commitments.

1.0 INTRODUCTION

The proposed license amendment changes Technical Specification (TS) 5.5.6, "Reactor Coolant Pump Flywheel Inspection Program". The changes are consistent with Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-421, 'Revision to RCP Flywheel Inspection Program (WCAP-15666)." The availability of this TS improvement was announced in the Federal Registeron October 22, 2003, as part of the consolidated line item improvement process (CLIIP).

2.0 DESCRIPTION

OF PROPOSED AMENDMENT Consistent with the NRC-approved TSTF-421, the proposed TS change includes the following revision to TS 5.5.6:

The examination interval for the RCP flywheels is changed from approximately 10 year intervals coinciding with the Inservice Inspection schedule as required by ASME Section Xi to 20 year intervals.

3.0 BACKGROUND

The background for this application is adequately addressed by the NRC Notice of Availability published on October 22, 2003 (68 FR 60422), NRC Notice for Comment 1 of 3

Exhibit A RCPFWIP published on June 24, 2003 -(68 FR 37590), TSTF-421, WCAP-15666, "Extension of Reactor Coolant Pump Motor Flywheel Examination," and the related NRC safety evaluation (SE) dated May 5, 2003.

4.0 REGULATORY REQUIREMENTS AND GUIDANCE The applicable regulatory requirements and guidance associated with this application are adequately addressed by the NRC Notice of Availability published on October 22, 2003 (68 FR 60422), NRC Notice for Comment published on June 24, 2003 (68 FR 37590), TSTF-421, WCAP-15666, and the related NRC SE.

5.0 TECHNICAL ANALYSIS

NMC has reviewed the model SE published on June 24, 2003 (68 FR 37590), and verified its applicability as part of the CLIIP. This verification included a review of the NRC staffs model SE, as well as the information provided to support TSTF-421 (including WCAP-1 5666 and the related SE dated May 5, 2003). NMC has concluded that the justifications presented in the TSTF proposal and the model SE prepared by the NRC staff are applicable to Prairie Island Nuclear Generating Plant (PINGP), Units I and 2, and justify this amendment for the incorporation of the changes to the PINGP TS.

6.0 REGULATORY ANALYSIS

A description of this proposed change and its relationship to applicable regulatory requirements and guidance was provided in the NRC notices related to the CLIIP, TSTF-421, topical report WCAP-15666, and the associated SE.

7.0 NO SIGNIFICANT HAZARDS CONSIDERATION NMC has reviewed the proposed no significant hazards consideration determination published in the Federal Register on June 24, 2003 (68 FR 37590) as part of the CLIIP.

NMC has concluded that the proposed determination presented in the Federal Register notice is applicable to PINGP and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

8.0 ENVIRONMENTAL EVALUATION NMC has reviewed the environmental evaluation included in the model SE published on June 24, 2003 (68 FR 37590) as part of the CLIIP. NMC has concluded that the NRC staff's findings presented in that evaluation are applicable to PINGP and the evaluation is hereby incorporated by reference for this application.
