By letter dated December 11, 2008, Arizona Public Service Company (APS) submitted an application pursuant to 10 CFR Part 54, to renew Operating License Nos. NPF-41, NPF-51, and NPF-74 for the Palo Verde Nuclear Generating Station (PVNGS), Units 1, 2, and 3. The staff is reviewing the information contained in the license renewal application and has identified, in the enclosure, an area where additional information is needed to complete the review. Further requests for additional information may be issued in the future.
Items in the enclosure were discussed with Angela Krainik, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-4053 or e-mail at Jonathan.Rowley@nrc.gov.

REQUEST FOR ADDITIONAL INFORMATION (RAI)
RAI B2.1.32-1 Under Aging Management Programs of Appendix B, the applicant states that the Protective Coating Monitoring and Maintenance Program,Section XI.S8 of NUREG-1801, Generic Aging Lessons Learned (GALL) Report, is not credited for aging management. Also, the Structures Monitoring Program in Appendix B, Section B2.1.32, states that Though coatings may have been applied to the external surfaces of structural members, no credit was taken for these coatings in the determination of aging effects for the underlying materials. The Structures Monitoring Program evaluates the condition of the coatings as an indication of the condition of the underlying materials. However, in addition to using the Protective Coating Monitoring and Maintenance Program to ensure the function of coated structures and components, the GALL Report states that Proper maintenance of protective coatings inside containment is essential to ensure operability of post-accident safety systems that rely on water recycled through the containment sump/drain system. Although the licensee does not credit the program for aging management, there needs to be adequate assurance that there is proper maintenance of the protective coatings in containment, such that they will not degrade and become a debris source that may challenge the Emergency Core Cooling Systems performance. Therefore, the staff requires the following additional information:
- 1. Please describe in detail, the coatings assessment program referenced in the supplemental response to GL 2004-02, dated February 28, 2008. How will the program ensure that there will be proper maintenance of the protective coatings inside containment and ensure operability of post-accident safety systems that rely on water recycled through the containment sump/drain system in the extended period of operation? Also, describe the frequency and scope of the inspections, acceptance criteria, and the qualification of personnel who perform containment coatings inspections.
