SUBJECT: LASALLE COUNTY STATION, UNITS 1 AND 2 - REQUEST FOR INFORMATION

FOR AN NRC DESIGN BASES ASSURANCE INSPECTION (PROGRAM):

IMPLEMENTATION OF THE ENVIRONMENTAL QUALIFICATION PROGRAM

INSPECTION REPORT 05000373/2017008; 05000374/2017008

Dear Mr. Hanson:

On June 26, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial

baseline Design Bases Assurance Inspection (Program) at the LaSalle County 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 inoffice 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: June 5, 2017

Preparation week: June 19 - 23, 2017

Onsite inspection weeks: June 26 - 30, 2017; and

July 10 - 14, 2017.

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.

B. Hanson -2-

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:

The first group lists information necessary for our initial inspection scoping

activities. This information should be provided to the lead inspector no later than

May 8, 2017. Prior to the bagman trip, on May 22, 2017, 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 June 5, 2017.

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 June 16, 2017. 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

June 26, 2017. 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. George M. Hausman. We understand that our

licensing contact for this inspection is Ms. Dwi Murray 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) 829-9743 or via e-mail at George.Hausman@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.

B. Hanson -3-

This letter, its enclosure, and your response (if any) 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 Title 10 of the Code of Federal Regulations 2.390, Public

Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

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

The following information is requested by May 8, 2017, 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 in lists should

contain enough information to be easily understood by someone who has knowledge

of light water reactor technology).
