Subject:

Acceptance of RiverBend Station Request for Relief RBS-ISI-018 RR for RPV support Skirt (ME9654)

Date: Thursday, October 25, 2012 3:07:44 PM Barry and Joey, By letter dated September 25, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML12277A387), Entergy Operations, Inc. (Entergy, the licensee) submitted relief request RBS-ISI-018 for the River Bend Station, Unit 1 (RBS).

The proposed request for relief is from certain American Society of Mechanical Engineers (ASME) and Pressure Vessel Code (BPV), 1992 Edition with 1993 Addenda, Section Xl, Sub Article IWF-2500 Inservice Inspection (ISI) requirements for Examination Category F-A, Supports. This relief is requested for the second 10-year interval of the Inservice Inspection Program. The purpose of this letter is to provide the results of the U.S. Nuclear Regulatory Commission (NRC) staffs acceptance review of this relief request.

The licensee has informed the NRC staff that these requests for relief were submitted beyond the 12 month timeframe following the second 120 month interval as specified under 10 CFR 50.55a(g)(5)(iv). This condition has been addressed in Entergy's Corrective Action Process. Pursuant to Section10 CFR 50.55a(g)(6)(i), the applicant shall demonstrate the examination coverage requirements are impractical for the subject welds and that imposition of these ASME Code requirements would create a burden on the licensee.

The NRC staff has reviewed your application and concluded that it does provide technical information in sufficient detail to enable the NRC staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed requests for relief in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised by separate correspondence.

If you have any questions, please contact me at (301) 415-1445.
