SUBJECT: FORT CALHOUN STATION - INITIAL REQUEST FOR INFORMATION
TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION NRC
INSPECTION REPORT 05000285/2012011
Dear Mr. Cortopassi:
On October 22, 2012, the NRC will begin a Component Design Bases Inspection at the Fort
Calhoun Station focused on the auxiliary feedwater system. A three-person team will perform
this inspection using NRC Inspection Procedure 71111.21, "Component Design Bases
Inspection."
The inspection focuses on components and operating experience throughout the auxiliary
feedwater system. 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 2-weeks of onsite inspection by the team. The inspection will consist
of one NRC inspector and two contractors that will focus on engineering. The current inspection
schedule is as follows:
Preparation Week: October 15, 2012
Onsite weeks: October 22, 2012
November 5, 2012
During the onsite weeks, the lead inspector will also request a tour of the auxiliary feedwater
system, both mechanical and electrical components. 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 general preparation and component sample selection. This
information should be available to the regional office no later than October 12, 2012. If 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 the
first day of onsite inspection to complete the required inspection samples. 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 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.
During the onsite portion of our inspection, we request that you make available a conference
room large enough to accommodate the inspection team. In that conference room, please
make available a computer with access to a printer, your condition reporting database, and your
documentation database.
The lead inspector for this inspection is Matthew Young. We understand that our licensing
engineer contact for this inspection is Erick Matzke. If there are any questions about the
inspection or the requested materials, please contact the lead inspector at (817) 200-1545 or via
e-mail at matt.young@nrc.gov.
This letter does not contain new or amended information collection requirements subject to the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection
requirements were approved by the Office of Management and Budget, Control Number
3150-0011. The NRC may not conduct or sponsor, and a person is not required to respond to,
a request for information or an information collection requirement unless the requesting
document displays a currently valid Office of Management and Budget control number.
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).
