Verbal Authorization of Request for Alternative - W3-ISI-015 Attendees:

By letter dated October, 19, 2009, Entergy Operations, Inc. (Entergy, the licensee) submitted the proposed alternative Request for Alternative W3-ISI-015, Inspection of Reactor Vessel Head In-Core Instrument Nozzles during Third Ten-Year Inservice Inspection Interval for Waterford Steam Electric Station, Unit 3. This request was as amended by letter dated November 2, 2009 that provided responses to the request for additional information and contained Request for Alternative W3-ISI-015, Revision 1. The licensee requested use of an alternative to the requirements of Title 10 of the Code of Federal Regulations (10 CFR) section 50.55a(g)(6)(ii)(D) which required augmentation of pressurized water reactor inservice inspection program with ASME Code Case N-729-1, subject to the conditions specified in paragraphs (g)(6)(ii)(D)(2) through (6). Specifically, the licensee proposed that performing a surface examination of the outside diameter of the in-core instrumentation (ICI) nozzle wetted surface would constitute a hardship due to high personnel radiological exposure without a compensating increase in the level of quality or safety.

Based on a review of Request for Alternative W3-ISI-015, Revision 1, the staff of the Piping and NDE Branch (CPNB) finds that the proposed alternative provides an acceptable level of quality and safety, and provides reasonable assurance of structural integrity. The staff also finds that a manual surface examination of the outside diameter for all ICI nozzles would present a significant hardship due to radiological exposure without a compensating increase in the level of quality or safety. Therefore, pursuant to 10 CFR 50.55a(a)(3)(ii), the use of the proposed alternative for the Waterford Steam Electric Station, Unit 3 is authorized for the 16th refueling cycle, beginning in fall of 2009 until the commencement of the 17th refueling cycle in spring of 2011.

All other requirements of Code Case N-729-1 and 10 CFR 50.55a(g)(6)(ii)(D)(6) not specifically requested and approved in this relief request remain applicable, including third party review by the Authorized Nuclear Inservice Inspector.
