RAI for PVNGS RR-40.doc October 22, 2009 Mr. Russell A. (Rusty) Stroud Licensing Section Leader Regulatory Affairs Palo Verde Nuclear Generating Station Arizona Public Service Company Rusty:
By letter dated July 1, 2009, Arizona Public Service Company (APS) submitted a request for relief from the requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI, for the Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3. The proposed relief request, RR No. 40, would increase the current inspection interval from 10 to 20 years for performing volumetric examination of certain reactor vessel pressure-retaining and full penetration welds at PVNGS. If granted, the relief would allow deferral of the next examinations of the subject welds until 2016 for Unit 1, 2026 for Unit 2, and 2027 for Unit 3, plus or minus one refueling cycle.
The U.S. Nuclear Regulatory Commission (NRC) staff has reviewed RR No. 40 and has determined that the information specified in the attached draft Request for Additional Information (RAI) is needed for the staff to complete its evaluation.
In order for the staff to complete its review in a timely manner, we request that you submit your response to the enclosed RAI by November 30, 2009. Please contact me if APS would like to have a conference call to discuss the draft RAI.
