SUBJECT: COLUMBIA GENERATING STATION - NOTIFICATION OF NRC DESIGN
BASES INSPECTION (05000397/2016007) AND INITIAL REQUEST FOR
INFORMATION
Dear Mr. Reddemann:
On June 6, 2016, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial baseline
Design Bases Inspection at the Columbia Generating Station. A 7-person team will perform this
inspection using the NRC Inspection Procedure 71111, Attachment 21M Design Bases
Inspection.
The inspection focuses on components and operator actions that have high risk and low design
margins. The samples reviewed during this inspection will be identified during an information
gathering visit and during the subsequent in-office preparation week. In addition, a number of
operating experience issues will also be selected for review.
The inspection will include an information gathering site visit by the team leader and a senior
reactor analyst, and two weeks of onsite inspection by the team. The inspection will consist of
five NRC inspectors and two contractors, of which six will focus on engineering and one on
operations. The current inspection schedule is as follows:
Onsite Information Gathering Visit: March 28-31, 2016
In-Office Preparation Week: May 23-27, 2016
Onsite Weeks: June 6-10, 2016, and June 20-24, 2016
The purpose of the information gathering visit is to meet with members of your staff to identify
potential risk-significant components and operator actions. The lead inspector will also request
a tour of the plant with members of your operations staff and probabilistic safety assessment
staff. During the onsite weeks, several days will be needed on the plant-referenced simulator in
order to facilitate the development of operator action-based scenarios. Additional information
and documentation needed to support the inspection will be identified during interviews with
engineering managers, engineers, and probabilistic safety assessment staff throughout the
inspection

Our experience with these inspections has shown that they are extremely resource intensive,
both for the NRC inspectors and the licensee staff. In order to minimize the inspection impact
on the site and to ensure a productive inspection, we have enclosed a request for information
needed for the inspection. The request has been divided into three groups. The first group lists
information necessary for the information gathering visit and for general preparation. This
information should be available to the regional office no later than April 27, 2016. Insofar as
possible, this information should be provided electronically to the lead inspector. Since the
inspection will be concentrated on high risk/low margin components, calculations associated
with your list of high risk components should be available to review during the information
gathering visit to assist in our selection of components based on available design margin.
The second group of documents requested is those items that the team will need access to
during the preparation week in order to finalize the samples to be inspected. The third group
lists information necessary to aid the inspection team in tracking issues identified as a result of
the inspection. It is requested that this information be provided to the lead inspector as the
information is generated during the inspection. Additional requests by inspectors will be made
throughout both onsite weeks for specific documents needed to complete the review of the
components selected. It is important that all of these documents are up to date and complete in
order to minimize the number of additional documents requested during the preparation and/or
the onsite portions of the inspection. In order to facilitate the inspection, we request that a
contact individual be assigned to each inspector to ensure information requests, questions, and
concerns are addressed in a timely manner.
The lead inspector for this inspection is Mr. Ronald A. Kopriva. We understand that our
licensing engineer contact for this inspection is Ms. Tracey Parmelee. If there are any questions
about the inspection or the requested materials, please contact the lead inspector by telephone
at 817-200-1104 or by e-mail at Ron.Kopriva@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.

Information Requested Prior to Information Gathering Visit (March 28, 2016)
The following information (Section 1 of this enclosure) should be sent to the Region IV office
in hard copy or electronic format (Certrec IMS preferred), to the attention of Ronald A.
Kopriva by March 28, 2016, to facilitate the reduction in the items to be selected for a final
list during the preparation week of May 2, 2016. The inspection team will finalize the
selected list during the prep week using the additional documents requested in Section II of
this enclosure. The specific items selected from the lists shall be available and ready for
