SUBJECT: DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 - REQUEST FOR
INFORMATION FOR AN NRC PILOT DESIGN BASES INSPECTION ON THE
IMPLEMENTATION OF THE ENVIRONMENTAL QUALIFICATION PROGRAM
INSPECTION REPORT 05000237/2016009; 05000249/2016009
Dear Mr. Hanson:
On June 27, 2016, the U. S. Nuclear Regulatory Commission (NRC) will begin the pilot program
portion of the triennial baseline Design Bases Inspection at Dresden Nuclear Power Station,
Units 2 and 3. This inspection will be performed in accordance with NRC Baseline Inspection
Procedure 71111.21N.
The inspection will focus on the implementation of the Environmental Qualification (EQ)
Program. 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 one week
of onsite inspection. The inspection team will consist of three NRC inspectors. The current
inspection schedule is as follows:
Bagman trip onsite week:
May 17 - 18, 2016
Inspection onsite week:
June 27, 2016, through July 1, 2016
The team will be preparing for the inspection, mainly during the week of June 20-24, 2016, as
discussed in the enclosure.
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 April 5, 2016.
Prior to the bagman trip on April 15, 2016, the lead inspector will communicate the
initial selected set of approximately 12 - 15 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 May 17, 2016.
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 15, 2016. 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 27, 2016. 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. Andrew Dunlop. We understand that our licensing
contact for this inspection is Mr. Dean Walker 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) 829-9726 or via e-mail at Andrew.Dunlop@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.

I.
Information Requested Prior to the Onsite Information Gathering/Bagman Week
The following information is requested by April 5, 2016, 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).
