SUBJECT: CALLAWAY PLANT - INITIAL INFORMATION REQUEST FOR NRC
TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION NRC
INSPECTION REPORT 05000482/2011006
Dear Mr. Heflin:
On January 24, 2011, the NRC will begin a triennial baseline Component Design Bases
Inspection at your Callaway Plant. 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
four NRC inspectors and two contractors, of which three will focus on engineering and one on
operations. The current inspection schedule is as follows:
Onsite information gathering visit: Week of January 24, 2011
Preparation Week: February 7, 2011
Onsite weeks: February 14, 2011
February 28, 2011
March 14, 2011
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. During the onsite weeks, several days of time will be needed on the plant-referenced
simulator in order to facilitate the development of operator action-based scenarios. Additional
information and documentation needed to support the inspection will be identified during the
inspection, including interviews with engineering managers, engineers, and probabilistic safety
assessment staff.

Our experience with these inspections has shown that 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 January 18, 2011. 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 is those items that the team will need access to
during the preparation week in order to finalize the samples to be inspected. 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. Additional requests by inspectors will be made
throughout all three onsite weeks for specific documents needed to complete the review of that
component/selection. 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. 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 Wayne Sifre. We understand that our licensing
engineer contact for this inspection is Mr. Petzel. If there are any questions about the
inspection or the requested materials, please contact the lead inspector at (817) 860-8193 or via
e-mail at wayne.sifre@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).
