NUCLEAR REGULATORY COMMISSION

REGION IV

ARLINGTON, TX 76011-4511

Mr. Richard L. Anderson, Vice President

Entergy Operations, Inc.

Russellville, AR 72802-0967

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

R. Anderson 2

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

(the Public Electronic Reading Room).

Sincerely,

/RA/

I. 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.
