SUBJECT: ARKANSAS NUCLEAR ONE - NOTIFICATION OF NRC DESIGN BASES
ASSURANCE INSPECTION (PROGRAMS) (05000313/2017007;
05000368/2017007) AND INITIAL REQUEST FOR INFORMATION
Dear Mr. Anderson:
On July 11, 2017, the NRC will begin an inspection at Arkansas Nuclear One. A three-person
team will perform this inspection using NRC Inspection Procedure 71111.21N, Design Bases
Assurance 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 the
electrical equipment program, as required by the Arkansas Nuclear One, Units 1 and 2,
Operating Licenses. Additionally, the team will perform an inspection of the equipment
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 to 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 will consist of three NRC inspectors. The
current inspection schedule is as follows:
On-site Information Gathering Visit: July 11, 2017
Preparation Week:
July 17-21, 2017
On-site Weeks:
July 24-28, 2017, and August 7-11, 2017
The purpose of the information gathering visit is to meet with members of your staff to become
familiar with the Arkansas Nuclear One, Units 1 and 2, environmental qualification programs.
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 equipment 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 during the

information gathering visit, July 11, 2017. Since the inspection will be concentrated on
environmental qualification, the equipment qualification master list should be available to
review during the information gathering visit to assist in our selection of components.
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 during the
on-site week 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 lead inspector for this inspection is James Drake. If there are any questions about the
inspection or the requested materials, please contact the lead inspector by telephone at
817-200-1558 or by email at James.Drake@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).
ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html

Information Requested for Information Gathering Visit (July 11, 2017)
The following information should be provided to the lead inspector in hard copy or
electronic format (Certrec IMS preferred), to the attention of James Drake by July 11,
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 one 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.
- Please provide requested documentation electronically in pdf files, Excel, or other
searchable formats, if possible. The information should contain descriptive names,
and be indexed and hyperlinked to facilitate ease of use. Information in "lists" should
contain enough information to be easily understood by someone who has knowledge
of pressurized water reactor technology. If requested documents are large and only
hard copy formats are available, please inform the inspector(s), and provide subject
documentation during the first day of the on-site inspection.
