SUBJECT:
RIVER BEND STATION - INFORMATION REQUEST FOR NRC TRIENNIAL
BASELINE COMPONENT DESIGN BASES INSPECTION NRC INSPECTION
REPORT 05000458/2008006
Dear Mr. Venable:
On May 12, 2008, the NRC will begin a triennial baseline Component Design Bases Inspection
at the River Bend Station. A six-person team will perform this inspection using NRC Inspection
Procedure 71111.21, Component Design Bases Inspection.
The inspection focuses on components and operator actions that have high risk and low design
margins. The samples reviewed during this inspection will be identified during an information
gathering visit and during the subsequent in-office preparation week. In addition, a number of
operating experience issues will also be selected for review.
The inspection will include an information gathering site visit by the team leader and a senior
reactor analyst, and 3-weeks of onsite inspection by the team. The inspection will consist of six
NRC inspectors, of which five will focus on engineering and one on operations. The current
inspection schedule is as follows:
Onsite information gathering visit: Week of April 28, 2008
Onsite weeks: May 12, 26 and June 2, 2008
The purpose of the information gathering visit is to meet with members of your staff to identify
potential risk-significant components and operator actions. The lead inspector will also request
a tour of the plant with members of your operations staff and probabilistic safety assessment
staff. Additional information and documentation needed to support the inspection will be
identified, including interviews with engineering managers, engineers, and probabilistic safety
assessment staff.

Our experience with these inspections has shown they 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, we have enclosed a request for information needed
for the inspection. The request has been divided into three groups. The first group lists
information necessary for the information gathering visit and for general preparation. This
information should be available to the regional office no later than March 17, 2008. Insofar as
possible, this information should be provided electronically to the lead inspector. Since the
inspection will be concentrated on high risk/low margin components, calculations associated
with your list of high risk components should be available to review during the information
gathering visit to assist in our selection of components based on available design margin.
The second group of documents requested are those items that the team will need access to
when onsite and after the inspection samples are selected. The third 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. It is important that all of these documents are up to date and
completed in order to minimize the number of additional documents requested during the
preparation and/or the onsite portions of the inspection. 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.
The lead inspector for this inspection is Mr. James F. Drake. We understand that our licensing
engineer contact for this inspection is Ms. Kristi Huffstatler. If there are any questions about the
inspection or the requested materials, please contact the lead inspector at (817) 276-6558 or via
e-mail at jfd@nrc.gov.
In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be
made available electronically for public inspection in the NRC Public Document Room or from
the Publicly Available Records (PARS) component of NRCs 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).
Sincerely,
