NPF-4/7 DPR-32/37 VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNITS 1 AND 2 SURRY POWER STATION UNITS 1 AND 2 PROPOSED TECHNICAL SPECIFICATION CHANGES TO EXTEND THE INSPECTION INTERVAL FOR REACTOR COOLANT PUMP FLYWHEELS USING THE CONSOLIDATED LINE ITEM IMPROVEMENT PROCESS Pursuant to 10 CFR 50.90, Virginia Electric and Power Company (Dominion) hereby requests amendments to the Technical Specifications (TS) for Surry Power Station (SPS) Units 1 and 2 and North Anna Power Station (NAPS) Units 1 and 2. The proposed amendments 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 lndustry/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 Register on October 22, 2003 as part of the consolidated line item improvement process (CLIIP). provides a description of the proposed changes and the requested confirmation of applicability for each station. Attachment 2 provides the existing TS pages marked-up to show the proposed change. Attachment 3 provides revised, clean TS pages.

Dominion requests approval of the proposed License Amendments by August 2005, with the amendments being implemented within 30 days.

Since the purpose of the CLllP is to streamline the License Amendment review process involving TSTF changes applicable to multiple plants and at the same time faciltate efficient NRC staff review of licensee submittals, Dominion requests that the NRC review of the attached proposed license amendments be performed by the same staff

Serial No.04-467 Docket Nos. 50-338/339/280/28 1 Attachment 1 Discussion of Change North Anna and Surry Power Station Extension of RCP Flywheel Inspection Interval North Anna Power Station Surry Power Station Units 1 and 2 Virginia Electric and Power Company (Dominion)

ATTACHMENT 1 Description and Assessment 1.O INTRODUCTION The proposed License Amendments change Surry Power Station (SPS) Units 1 and 2 Technical Specifications (TS) Table 4.2-1, Miscellaneous Inspections and North Anna Power Station (NAPS) Units 1 and 2 TS 5.5.6, Reactor Coolant Pump Flywheel Inspection Program. The changes are consistent with lndustry/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 Register on 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 changes include the following revisions:

0 SPS TS Table 4.2-1, Item 1.3, is revised to change the examination interval for the RCP flywheel from 10 year intervals to 20 year intervals and add that the provisions of Specification 4.0.2 are not applicable 0 NAPS TS 5.5.6 is revised to change the examination interval for the RCP flywheel from 10 year intervals to 20 year intervals and remove the provisions that SR 3.0.2 and SR 3.0.3 are applicable to the Reactor Coolant Pump Flywheel Inspection Program surveillance frequency

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 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-I 5666, and the related NRC SE.

5.0 TECHNICAL ANALYSIS

Dominion 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-15666 and the related SE dated May 5, 2003). Dominion has

concluded that the justifications presented in the TSTF proposal and the model SE prepared by the NRC staff are applicable to SPS Units 1 and 2 and NAPS Units 1 and 2 and justify this amendment for the incorporation of the changes to the NAPS and SPS TS. Since, the NRC staffs model SE approved extending the interval to a maximum of 20 years, no provision for extending this inspection interval is included in the proposed 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 Dominion has reviewed the proposed no significant hazards consideration determination published on June 24, 2003 (68 FR 37590) as part of the CLIIP. Dominion has concluded that the proposed determination presented in the notice is applicable to SPS and NAPS and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

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

9.0 PRECEDENT This application is being made in accordance with the CLIIP. Dominion is not proposing variations or deviations from the TS changes described in TSTF-421 or the NRC staffs model SE published on June 24,2003 (68 FR 37590).
