SUBJECT:
QUAD CITIES NUCLEAR POWER STATION, UNITS 1 AND 2
REQUEST FOR INFORMATION FOR AN NRC TRIENNIAL BASELINE
COMPONENT DESIGN BASES INSPECTION (CDBI) INSPECTION REPORT
05000254/2008007; 05000265/2008007(DRS)
Dear Mr. Pardee:
On September 22, 2008, the NRC will begin a triennial baseline Component Design Bases
Inspection (CDBI) at Quad Cities Nuclear Power Station, Units 1 and 2. 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 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. 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: September 22-26, 2008;
October 6-10, 2008; and
October 20-24, 2008.
The team will be preparing for the inspection, mainly during the week of September 15-19, 2008,
as discussed in the attached enclosure. A Region III Senior Reactor Analyst may accompany the
inspection team during the week of September 22-26, 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
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 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 provided to the lead inspector no later than August 18, 2008.
By August 27, 2008, the lead inspector will communicate the initial selected set of
approximately 30-high risk components.
The second group of documents requested is 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 provided to the lead inspector at the Regional Office
no later than September 8, 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 onsite on September 15-19, 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. Wally Beck 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.
In accordance with 10 CFR 2.390 of the NRCs 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 NRCs document system
(ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the
Public Electronic Reading Room).
