SUBJECT: COLUMBIA GENERATING STATION - NOTIFICATION OF INSPECTION
(INSPECTION REPORT 05000397/2011005) AND REQUEST FOR
INFORMATION
Dear Mr. Reddemann:
On December 5, 2011, the 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 Columbia 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 on-site 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 28, 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 on-site 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 Cherie Sonoda of your licensing
organization. If there are any questions about this inspection or the material requested, please
contact the inspector, Ron Cohen, at 509-845-1369 or by email at ronald.cohen@nrc.gov.

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)

The following information should be sent to Ronald Cohen (address at the end) in hard copy or
electronic format (ims.certrec.com or compact disc preferred) to facilitate the selection of
specific items that will be reviewed during the on-site inspection week. The inspector will select
specific items from the information requested below and then request from your staff additional
documents needed during the on-site inspection weeks. Also, we request that you categorize
the documents in your response with the numbered list below. Please provide requested
documentation electronically if possible. If requested documents are large and only hard copy
formats are available, please inform the inspector and provide subject documentation during the
first day of the on-site inspection. If you have any questions regarding this information request,
please call the inspector as soon as possible.
