SUBJECT: WOLF CREEK GENERATING STATION - REQUEST FOR INFORMATION
(INSPECTION REPORT 05000482/2011003) RELATED TO TI 2515/177
Dear Mr.Sunseri:
On May 2, 2011, the U.S. Nuclear Regulatory Commission (NRC) will begin the on-site portion
of the Gas Accumulation Management in Emergency Core Cooling, Decay Heat Removal, and
Containment Spray Systems Temporary Instruction at your Wolf Creek 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 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 March 21, 2011. Any
documents mailed to the inspector should be shipped to his attention at the Region IV
address. Upon review of these documents, the inspectors will select additional
documentation for review upon arrival. By April 8, 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 May 2, 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 Bill Muilenburg of your licensing
organization. If there are any questions about this inspection or the material requested, please
contact the inspector, Greg Pick, at 817-860-8270 or by email at greg.pick@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
Wolf Creek Nuclear Operating Corporation -2-
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
site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
