SUBJECT:
DUANE ARNOLD ENERGY CENTER
REQUEST FOR INFORMATION AN NRC BIENNIAL
BASELINE COMPONENT DESIGN BASES INSPECTION (CDBI)
Dear Mr. Anderson:
On February 11, 2008, the NRC will begin a biennial baseline Component Design Bases
Inspection (CDBI) at the Duane Arnold Energy Center. A team of six inspectors will perform this
3-week inspection. This inspection will be performed in accordance with NRC Baseline Inspection
Procedure (IP) 71111.21.
The CDBI inspection focuses on components that have high risk and low design margins. The
components to be reviewed during this baseline inspection will be identified during an in-office
preparation week prior to the first week of the on-site inspection. In addition, a number of risk
significant operator actions and operating experience issues, associated with the component
samples, will also be selected for review.
The inspection will include three weeks on-site, including the information gathering during the first
on-site week. The inspection team will consist of six NRC inspectors, of which five will focus on
engineering and one on operations. The current inspection schedule is as follows:
On-site weeks: February 11, 2008, through February 15, 2008;
February 25, 2008, through February 29, 2008; and
March 10, 2008, through March 14, 2008.
The team will be preparing for the inspection, mainly during the week of February 4, 2008, as
discussed in the attached enclosure. A Region III Senior Reactor Analyst may accompany the
inspection team during the week of February 11, 2008, to review probabilistic risk assessment
data, and assist in identifying risk significant components, which will be reviewed during the
inspection.
Experience with previous baseline design inspections of similar depth and length has shown that
these type of inspections are 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 on-site portions of
the inspection. Insofar as possible, this information should be provided electronically to the lead
inspector. The information request has been divided into three groups:
The first group lists information necessary for our initial inspection scoping activities.
This information should be available to the lead inspector no later than January 10, 2008. By
January 23, 2008, the lead inspector will communicate the initial selected set of approximately
30 high risk components.
The second group of documents requested are those items needed to support our in-office
preparation activities. This set of documents, including the calculations associated with the
initial selected components, should be available at the Regional Office no later than
January 31, 2008. 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 on February 11, 2008. 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. Bob 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) 829-9726 or via e-mail at axd7@nrc.gov.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its
enclosure will be available electronically for public inspection in the NRC Public Document Room
or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS),
accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public
Electronic Reading Room).
Sincerely,
/RA by Andrew Dunlop Acting For/
