SUBJECT: DUANE ARNOLD ENERGY CENTERREQUEST FOR INFORMATION
FOR AN NRC DESIGN BASES ASSURANCE INSPECTION (PROGRAM):
IMPLEMENTATION OF THE ENVIRONMENTAL QUALIFICATION PROGRAM;
INSPECTION REPORT 05000331/2018010
Dear Mr. Curtland:
On April 23, 2018, the U. S. Nuclear Regulatory Commission (NRC) will begin a triennial
baseline Design Bases Assurance Inspection (Program) at the Duane Arnold Energy
Center. 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 3 NRC inspectors. The current inspection
schedule is as follows:
Bagman trip onsite week: February 19, 2018
Team preparation week: April 16-20, 2018
Onsite inspection weeks: April 23-27, 2018, and May 7-11, 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:
D. Curtland -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 5, 2018.
Prior to the bagman trip on January 19, 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 19, 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
April 5, 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
April 23, 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. Néstor J. Féliz Adorno. We understand that our
licensing contact for this inspection is Mr. B. Murrell 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) 829-9739 or via e-mail at Nestor.Feliz-Adorno@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.
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,

I. Information Requested Prior to the Onsite Information Gathering/Bagman Week
The following information is requested by January 5, 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
in lists should contain enough information to be easily understood by someone who
has knowledge of light water reactor technology.
