SUBJECT:
FORT CALHOUN STATION - NOTIFICATION OF NRC TRIENNIAL HEAT
EXCHANGER INSPECTION (05000285/2011005)
Dear Mr. Bannister:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission Region IV
staff will conduct a triennial heat sink performance inspection at your Fort Calhoun Station. The
inspection will be comprised of one reactor inspector from the NRC Region IV office. The
inspection will be conducted in accordance with Inspection Procedure 71111.07, "Heat Sink
Performance."
The schedule for the inspection is as follows:
Onsite inspection - November 14-18, 2011
Experience has shown that this inspection is resource intensive both for the NRC inspectors
and your staff. In order to minimize the impact to your onsite resources and to ensure a
productive inspection, we have enclosed a request for documents needed for this inspection.
Please note that the documents are requested to be provided by October 31, 2011. We
request, that during the onsite inspection week, you ensure that copies of analyses, evaluations,
or documentation regarding the implementation and maintenance of your heat exchanger
program are available. Of specific interest are those documents that establish that your heat
exchanger program satisfies NRC regulatory requirements and conforms to applicable NRC
guidance. Also, appropriate personnel knowledgeable of safety-related heat exchangers should
be available to support the inspector at the site during the inspection.
We have discussed the schedule for this inspection activity with your staff and understand that
our regulatory contact for this inspection will be Richard Acker of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspector, Dustin Reinert, at 817-860-8244 or by email, dustin.reinert@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.

Inspector:
Dustin Reinert, Reactor Inspector
Information Requested for the In-Office Preparation Week
The following information should be sent to the Region IV office in hard copy or electronic
format (ims.certrec.com database preferred), in care of Dustin Reinert, by October 31, 2011.
The inspectors will select specific items from the information requested below and then request
from your staff additional documents needed during the onsite inspection week. Also, we
request that you categorize the documents in your response with the numbered list below.
Please provide requested documentation electronically if possible. If requested documents are
large and only hard copy formats are available, please inform the inspector, and provide subject
documentation during the first day of the onsite inspection. If you have any questions regarding
