SUBJECT:
- INFORMATION
REQUEST FOR AN NRC BIENNIAL BASELINE COMPONENT DESIGN BASES
INSPECTION (CDBI) 05000266/2006006 (DRS); 05000301/2006006 (DRS)
Dear Mr. Koehl:
On August 14, 2006, the NRC will begin a biennial baseline Component Design Bases
Inspection (CDBI) at the
. A team of seven inspectors will
perform this 4-week inspection. This inspection will be performed in accordance with revised
NRC Baseline Inspection Procedure (IP) 71111.21 and replaces the biennial Safety System
Design and Performance Capability inspection.
The CDBI inspection focuses on components which 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 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 4 weeks of on-site inspection. This will include one to two weeks of
on-site information gathering. 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: August 14, 2006, August 28, 2006, September 11, 2006, and
September 25.
The team will be preparing for the inspection mainly during the weeks of August 14 and 21, 2006,
as discussed in the attached enclosure. A Region III Senior Reactor Analyst will accompany the
inspection team during the week of August 14, 2006, 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. The information request has been divided as follows:
The first group lists information necessary for a productive inspection preparation. This
information should be available to the Regional Office by no later than July 28, 2006, or sooner.
The second group of documents requested are those items necessary for the teams in-office
(August 21, 2006) preparation activities. During the in-office preparation week, the team may
identify additional information needed. This information should be available by August 28, 2006
(on-site week). The last group lists information necessary to aid the inspection team in tracking
issues identified as a result of the inspection. It is requested that this information be provided to
the lead inspector as the information is generated during the inspection.
The lead inspector for this inspection is Mr. Robert Daley. We understand that our regulatory
affairs contact for this inspection is Ms. Fritzi Flenji of your organization. In order to facilitate the
inspection, we request that a contact individual be assigned to each inspector to ensure
information requests, questions, and concerns are addressed in a timely manner. If there are
any questions about the inspection or the material requested in the Enclosure, please contact the
lead inspector at (630) 829-9749 or via e-mail at RCD@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). ADAMS is accessible from the NRC Web site at
http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
