REQUEST FOR ADDITIONAL INFORMATION (RAI)

REGARDING PROPOSED AMENDMENT ON CHANGES TO THE STEAM GENERATOR INSPECTION REPORTING CRITERIA KEWAUNEE NUCLEAR POWER PLANT DOCKET NO. 50-305 In letter dated December 19, 2002, Nuclear Management Company (NMC) submitted changes to the technical specifications (TSs) for the Kewaunee Nuclear Power Plant. NMC proposed to change: (1) the tube plugging reporting requirement from the current 30 days to 60 days in TS 4.2.b.7.a and (2) the C-3 category notification from 10 CFR 50.72(b)(2)(ii) to 10 CFR 50.72(b)(3)(ii) in TS 4.2.b.7.c. To complete its review, the U.S. Nuclear Regulatory Commission (NRC) staff requests the following additional information:

1. In the proposed TS 4.2.b.7.a, it is stated that ...Following each in-service inspection of steam generator tubes during which tubes are plugged, the number of tubes plugged shall be reported to the Commission within 60 days... The current TS requires a 30-day reporting period. The licensee proposed the 60-day reporting requirement to be consistent with 10 CFR 50.73, License Event Report System.

Please provide a technical basis for the proposed change: (a) Please cite the specific subparagraph in 10 CFR 50.73 that is applicable to the tube plugging report and explain why that subparagraph is applicable, and (b) 10 CFR 50.73 requires that licensees submit a license event report within 60 days of the discovery of an event. Please clarify when the 60-day period starts, e.g., from the completion of the eddy current data analysis of the steam generator inspection results, completion of the tube plugging effort, restart of the unit, or, closure of the steam generator manways.

2. In the proposed TS 4.2.b.7.c, it is stated that ...If a steam generator tube inspection result falls into Category C-3, the Commission shall be promptly notified according to requirements of 10 CFR 50.72(b)(3)(ii)... This will change the 4-hour notification in the current TS to the 8-hour notification as specified 10 CFR 50.72(b)(3)(ii).

Please provide a technical basis for extending the notification from 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />s:

(a) Please cite the specific subparagraph in 10 CFR 50.72(b)(3)(ii) that is applicable to the C-3 category notification and to explain why the subparagraph is applicable, (b) The NRC staff believes that 10 CFR 50.72(c), Followup Notification, is also applicable to the C-3 category notification. Explain why was 10 CFR 50.72(c) not cited in the proposed TS 4.2.b.7.c, and (c) Confirm that when a C-3 category is established, the licensee is required by 10 CFR 50.73, Licensee event report system, to submit a written license event report.
