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.

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.
