Mr. Adam C. Heflin, President
Chief Executive Officer
and Chief Nuclear Officer
Wolf Creek Nuclear Operating Corporation

SUBJECT: WOLF CREEK GENERATING STATION - NOTIFICATION OF AN NRC
TRIENNIAL FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION
REPORT 05000482/2017008) AND REQUEST FOR INFORMATION
Dear Mr. Heflin:
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 Wolf Creek
Generating Station in October 2017. 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 NRCs baseline fire protection
inspection procedure.
The schedule for the inspection is as follows:
- Information gathering visit: August 22 - 23, 2017
- Onsite inspection: October 2 - 6, 2017
October 16 - 20, 2017
The purpose of the information gathering visit is to obtain information and documentation
needed to support the inspection and to become familiar with the fire protection program, fire
protection features, post-fire safe shutdown capabilities, plant layout, and mitigating strategies
to address Section B.5.b of NRC Order EA-02-026, Order for Interim Safeguards and Security
Compensatory Measures, dated February 25, 2002, and 10 CFR 50.54(hh)(2).
The team lead will participate in the information gathering visit to select the fire areas for
evaluation, identify additional documents needed to support the inspection, obtain unescorted
A. Heflin 2
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 the NRC Region IV office 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
availability of knowledgeable plant engineering and licensing 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 fire
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 [10 CFR 50.54(hh)(2)] 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 that appropriate personnel are available to support
the team at the site during the inspection. These personnel should be knowledgeable of the
plant systems required to achieve and maintain safe shutdown conditions from inside and
outside the control room, the electrical aspects of the post-fire safe shutdown analyses, the
reactor plant fire protection systems, and the fire protection program and its implementation.
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 under 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 NRCs 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
http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
