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. | |||

This letter does not contain new or amended information collection requirements subject to the | |||
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection | |||
requirements were approved by the Office of Management and Budget, control number | |||
3150-0011. The NRC may not conduct or sponsor, and a person is not required to respond to, | |||
a request for information or an information collection requirement unless the requesting | |||
document displays a currently valid Office of Management and Budget control number. | |||
In accordance with Code of Federal Regulations, Title 10, Part 2.390 of the NRC's Rules of | |||
Practice, a copy of this letter and its enclosure will be available electronically for public | |||
inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) | |||
component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web | |||
