1.0 INTRODUCTION

The proposed license amendment changes Technical Specification (TS) 6.7.6.m, "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 FederalRegister 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 change includes the following revision to TS 6.7.6.m:

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

The TS change provided in TSTF-421 was based on the premise that the licensee's TS would be consistent with the Standard TS (STS) for Westinghouse Plants (NUREG-1431) as follows:

5.5.7 Reactor Coolant Pump Flywheel Inspection Program This program shall provide for the inspection of each reactor coolant pump flywheel per the recommendations of Regulatory Position C.4.b of Regulatory Guide 1.14, Revision 1, August 1975.

In lieu of Position C.4.b(1) and C.4.b(2), a qualified in-place UT examination over the volume from the inner bore of the flywheel to the circle one-half of the outer radius or a surface examination (MT and/or PT) of exposed surfaces of the removed flywheels may be conducted at 20 year intervals.

Current Seabrook TS 6.7.6.m, Reactor Coolant PumpFlywheel Inspection Program, neither includes the first STS paragraph above nor does it state that the test methods are in lieu of Positions C.4.b.(1) and C.4.b.(2) in Regulatory Guide (RG) 1.14. Therefore, the proposed amendment also revises Seabrook TS 6.7.6.m to reference RG 1.14 for consistency with the STS as shown below.

m. Reactor Coolant Pump Flywheel Inspection Program In addition to the requirements of Specification 4.0.5, each reactor coolant pump flywheel shall be inspected per the recommendationsof Regulatory Position C.4.b of Regulatory Guide 1.14, Revision 1, August 1975 at least once every 1-0 20 years. In lieu of Position C.4.b(1) and C.4.b(2), this inspection shall be by either of the following examinations:

2

a. An in-place examination, utilizing ultrasonic testing, over the volume from the inner bore of the flywheel to the circle of one-half the outer radius; or
b. A surface examination, utilizing magnetic particle testing and/or penetrant testing, of the exposed surfaces of the disassembled flywheel.

Although not specifically addressed in TSTF-421, this change is administrative in nature.

Including a reference to RG 1.14 in TS 6.7.6.m does not change the technical requirements of the Reactor Coolant Pump Flywheel Inspection Program; rather, it establishes consistency with STS 5.5.7 on which TSTF-421 was based. This change does not alter the conclusion in the significant hazards consideration determination published on June 24, 2003 as part of the CLIIP.

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-1 5666, "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

NextEra 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). NextEra has concluded that the justifications presented in the TSTF proposal and the model SE prepared by the NRC staff are applicable to Seabrook Station and justify this amendment for incorporation of the changes to the Seabrook 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-1 5666, and the associated SE.

7.0 NO SIGNIFICANT HAZARDS CONSIDERATION NextEra has reviewed the proposed no significant hazards consideration determination published on June 24, 2003 (68 FR 37590) as part of the CLIIP. NextEra has concluded that the proposed determination presented in the notice is applicable to Seabrook and the determination is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a).

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

9.0 PRECEDENT This application is being made in accordance with the CLIIP. Byron and Braidwood stations received similar amendments to extend the reactor coolant pump flywheel inspections in accordance with TSTF-421 in September 2010. NextEra has proposed a minor change in addition to the TS changes described in TSTF-421. The change is administrative in nature and is included to establish consistency with the STS on which TSTF-421 was based.
