SUBJECT: BRAIDWOOD STATION UNITS 1 AND 2REQUEST FOR INFORMATION

FOR AN NRC DESIGN BASES ASSURANCE INSPECTION (PROGRAM):

IMPLEMENTATION OF THE ENVIRONMENTAL QUALIFICATION PROGRAM

INSPECTION REPORT 05000456/2018012; 05000457/2018012

Dear Mr. Hanson:

On March 12, 2018, the U. S. Nuclear Regulatory Commission (NRC) will begin a Triennial

Baseline Design Bases Assurance Inspection (Program) at your Braidwood Station, Units 1

and 2. This inspection will be performed in accordance with NRC Baseline Inspection

Procedure 71111.21N, Attachment 1.

The Design Bases Assurance Inspection will focus on the implementation of the Electrical

Equipment Environmental Qualification (EQ) Program to verify you are maintaining the qualified

status of equipment during the life of the plant. The EQ components to be reviewed during this

baseline inspection will be identified during the in-office preparation week that occurs prior to the

onsite inspection week.

The inspection will include a bagman trip to support selection of components and 2 weeks of

onsite inspection. The inspection team will consist of three NRC inspectors. The current

inspection schedule is as follows:

Bagman trip onsite week: February 12-15, 2018;

Preparation week: March 5-9, 2018;

Onsite inspection weeks: March 12-16, 2018; and March 26-30, 2018.

Experience with previous baseline design inspections of similar depth and length has shown

that this type of inspection is 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 for both parties, we have enclosed a request for information needed for the

inspection.

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. Insofar as possible, this information should be provided electronically to the lead

inspector. The information request has been divided into four groups:

B. Hanson -2-

The first group lists information necessary for our initial inspection scoping activities.

This information should be provided to the lead inspector no later than January 23, 2018.

Prior to the bagman trip on January 31, 2018, the lead inspector will communicate the

initial selected set of approximately 12 EQ components.

The second group of documents requested is those items needed to support the

bagman trip. This set of documents should be available to the lead inspector onsite

on February 12, 2018.

The third group of documents requested is those items needed to support our

in-office preparation activities for the selected set of 6-9 EQ components. This set of

documents should be provided to the lead inspector at the Regional Office no later than

February 28, 2018. During the in-office preparation activities, the team may identify

additional information needed to support the inspection.

The last group includes the additional information above as well as plant specific

reference material. This information should be available to the team onsite on

March 12, 2018. It is also requested that corrective action documents and/or

questions developed during the inspection be provided to the lead inspector as

the documents are generated.

The lead inspector for this inspection is Mr. John V. Bozga. We understand that our licensing

contact for this inspection is Mr. Richard Schliessmann of your organization. If there are any

questions about the inspection or the material requested in the enclosure, please contact the

lead inspector at 630-829-9613.

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.

This letter and its enclosure will be made available for public inspection and copying at

http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in

accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA Andrew Dunlop Acting for/

I. Information Requested Prior to the Onsite Information Gathering/Bagman Week

The following information is requested by January 23, 2018, or sooner, to facilitate

inspection preparation. If you have any questions regarding this information, please call

the team leader as soon as possible. (Please provide the information electronically in

pdf files, Excel, or other searchable formats, preferably on some portable electronic

media (e.g., CD-ROM, DVD, etc.). The portable electronic media should contain

descriptive names, and be indexed and hyperlinked to facilitate ease of use. Information
