SUBJECT:
COOPER NUCLEAR STATION - NOTIFICATION OF NRC DESIGN BASES
ASSURANCE INSPECTION (PROGRAMS) (05000298/2017007) AND INITIAL
REQUEST FOR INFORMATION
Dear Mr. Higginbotham:
On August 2, 2017, the NRC will begin an inspection at the Cooper Nuclear Station. A
three-person team will perform this inspection using NRC Inspection Procedure 71111.21N,
Design Bases Inspection (Programs), Attachment 1, Environmental Qualification Under
10 CFR 50.49 Programs, Processes, and Procedures.
This inspection will evaluate the implementation of the environmental qualification of electrical
equipment program, as implemented by the Cooper Nuclear Station Operating License.
Additionally, the team will perform an inspection of the environmental qualification
documentation files to verify that electrical equipment important to safety meets the
requirements of 10 CFR 50.49. The team will select components that will be subjected to harsh
environments and required mitigate the consequences of a design basis accident.
The inspection will include an information gathering site visit by the team leader and two weeks
of on-site inspection by the team. The inspection team will consist of three NRC inspectors.
The current inspection schedule is as follows:
On-site Information Gathering Visit: August 2, 2017
Preparation Week: August 7, 2017
On-site Weeks: August 14-18, 2017, and August 28-August 31, 2017
The purpose of the information gathering visit is to meet with members of your staff to become
familiar with the Cooper Nuclear Station environmental qualification program. The lead
inspector will request a meeting with your personnel to discuss the site environmental
qualification program and procedures. Additionally, the lead inspector will request a discussion
with your staff to become familiar with the environmental qualification regulations and standards
to which the site is committed. Additional information and documentation needed to support the

inspection will be identified during the inspection, including interviews with engineering
managers and engineers.
Our experience with these inspections has shown that they are 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. This information should be made available to the lead inspector by July 31,
2017. Since the inspection will be concentrated on the environmental qualification of the
equipment, the equipment qualification master list should be available to review prior to the
information gathering visit to assist in our selection of components.
It is requested that this information be provided to the team leader as the information is
generated during the inspection. Additional requests by inspectors will be made during the
on-site weeks for specific documents needed to complete the review of that
component/selection. 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 on-site 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 team leader for this inspection is Gerond A. George, Senior Reactor Inspector. We
understand that our licensing engineer contact for this inspection is D. W. Van Der Kamp.
If there are any questions about the inspection or the requested materials, please contact the
team leader by telephone at 817-200-1562 or by e-mail at Gerond.George@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 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be
made available electronically for public inspection in the NRC Public Document Room or from
the Publicly Available Records (PARS) component of NRCs document system (ADAMS).

Information Requested for Information Gathering Visit (July 31, 2017)
The following information should be provided to the lead inspector in hard copy or
electronic format (Certrec IMS preferred), to the attention of Gerond A. George, Senior
Reactor Inspector, by July 31, 2017, to facilitate the reduction in the items to be selected
for a final list of components. The inspection team will finalize the selected list during the
prep week using the documents requested in this enclosure. The specific items selected
from the lists shall be available and ready for review on the day indicated in this request.
