SUBJECT: PALO VERDE NUCLEAR GENERATING STATION - NOTIFICATION OF INSPECTION (NRC INSPECTION REPORT 05000528/2011005, 05000529/2011005, AND 05000530/2011005) AND REQUEST FOR INFORMATION
Dear Mr. Edington:
The purpose of this letter is to notify you that on December 5, 2011, the U.S. Nuclear Regulatory Commission (NRC), Region IV staff will begin the onsite portion of the Gas
Accumulation Management in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems Temporary Instruction at your Palo Verde Nuclear Generating Station. This inspection will be performed in accordance with NRC Temporary Instruction (TI) 2515/177.
Experience has shown that this inspection is resource intensive both for the NRC inspectors and your staff. In order to minimize the impact to your onsite resources and to ensure a
productive inspection, we have enclosed a request for documents needed for this inspection. The documents have been divided into two groups.
- The first group lists information necessary for our initial inspection scoping and in-office preparation activities. This information should be separated by information request number,
especially if provided electronically (e.g., folder with the information request number). This information should be available to the inspector no later than November 21, 2011. Upon review of these documents, the inspectors will select additional documentation for review upon arrival. By December 1, 2011, the inspector will communicate the initial selected samples.
- The second group of documents requested is needed to support our onsite inspection activities. This set of documents should be available to the inspector on December 5, 2011. It is also requested that corrective action documents and responses to questions developed during the inspection be provided to the inspector as the documents are generated.
We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Del Elkinton
of your licensing organization. If there are any questions about this inspection or the material requested, please contact either Abin Fairbanks, at (817) 860-8158 or by email at Abin.Fairbanks@nrc.gov, or Dustin Reinert, at (817) 860-8244 or by email at Dustin.Reinert@nrc.gov.

2. List of changes (with a short description and tracking number) to the final safety analysis report (FSAR), technical specifications, technical specification bases, and technical requirements manual associated with the resolution of GL 2008-01.
3. List of calculations associated with GL 2008-01, including calculations that have been changed or created in response to GL 2008-01 (with a short description of the calculation and the change).
4. List (with a short description) of gas intrusion mechanisms that apply to the plant and the affected system locations (e.g., identify the source, conditions, and expected void locations). Also, include a short description of how each gas intrusion mechanism has been addressed (e.g., plant hardware modification, procedure change).
