SUBJECT: FORT CALHOUN STATION - NOTIFICATION OF NRC TRIENNIAL FIRE
PROTECTION BASELINE INSPECTION (05000285/2012007) AND REQUEST
FOR INFORMATION
Dear Mr. Bannister:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC),
Region IV staff will conduct a triennial fire protection baseline inspection at the Fort Calhoun
Station in March and April 2012. The inspection team will be comprised of four reactor
inspectors from the NRC Region IV office. The inspection will be conducted in accordance with
Inspection Procedure 71111.05T, "Fire Protection (Triennial)," the NRC's baseline fire protection
inspection procedure.
The schedule for the inspection is as follows:
- Information gathering visit: February 28 - 29, 2012
- Onsite inspection: March 26 - 30, 2012
April 09 - 13, 2012
The purpose of the information gathering visit is to obtain information and documentation
needed to support the inspection, to become familiar with the fire protection programs, fire
protection features, post-fire safe shutdown capabilities and plant layout, and mitigating
strategies to address Section B.5.b of the Interim Compensatory Measures (ICM)
Order EA-02-026, of February 25, 2002/10 CFR 50.54(hh)(2). Four individuals will participate in
the information gathering visit to select the fire areas for evaluation, identify additional
documents needed to support the inspection, obtain unescorted access, and meet with the key
personnel who will support the inspection. The fire area selection will require a walkdown of
candidate fire areas in company with key personnel from your staff. The enclosure to this letter
provides an initial list of the documents the team will need for their review. We request that your
staff transmit copies of the documents listed in the enclosure to the NRC Region IV office for
team use in preparation for the inspection. Please send this information so that it will arrive in
our office in Arlington, Texas, by the dates listed in the enclosure.
During the information gathering visit, the team will also discuss the following inspection support
administrative details: office space size and location; specific documents requested to be made
available to the team in their office spaces; arrangements for reactor site access; and the
-2-
availability of knowledgeable plant organization personnel to serve as
points of contact during the inspection.
We request that during the onsite inspection weeks, you ensure that copies of analyses,
evaluations, or documentation regarding the implementation and maintenance of the
protection program, including post-fire safe shutdown capability, be readily accessible to the
team for their review. Of specific interest for the fire protection portion of the inspection are
those documents that establish that your fire protection program satisfies the NRC regulatory
requirements and conforms to applicable NRC and industry fire protection guidance. For the
B.5.b portion of the inspection, those documents implementing your mitigating strategies and
demonstrating the management of your commitments for the strategies are of specific interest.
Also, please ensure the availability of appropriate personnel knowledgeable of: (1) plant
systems required to achieve and maintain safe shutdown conditions from inside and outside the
control room, (2) the electrical aspects of the post-fire safe shutdown analyses, (3) reactor plant
fire protection systems, and (4) the fire protection program and its implementation should be
available to support the team at the site during the inspection.
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 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 ~~=...:.;:....::.;;...;.;:..:.:...;:;.~..=...;".=~"'

Your cooperation and support during this inspection will be appreciated. If you have questions
concerning this inspection or the inspection team's information or logistical needs, please
contact John Mateychick, the team lead inspector, in the Region IV office at (817) 200-1560, or
