SUBJECT: SEQUOYAH NUCLEAR PLANT (UNIT 1 AND UNIT 2) - NOTIFICATION OF A
TRIENNIAL FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION
REPORT NOS. 05000327/2014007 AND 05000328/2014007)
Dear Mr. Shea:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
staff will conduct a triennial fire protection baseline inspection at Sequoyah Nuclear Plant, Unit 1
and Unit 2. The inspection team will be led by Omar R. López-Santiago, a Senior Reactor
Inspector from the NRC Region II Office. The team will be composed of personnel from the
NRC Region II Office. The inspection will be conducted in accordance with IP 71111.05T, the
NRC's baseline fire protection inspection procedure, dated January 31, 2013.
On October 23, 2013, during a telephone conversation between Mr. Jonathan Johnson
(Licensing Program Manager) and Mr. López-Santiago our respective staffs confirmed
arrangements for a three-day information gathering onsite visit and a two-week onsite
inspection. The schedule for the inspection is as follows:
- Information Gathering Visit: January 7 - 9, 2014
- Week 1 of onsite inspection: January 27 - 31, 2014
- Week 2 of onsite inspection: February 10 - 14, 2014
The purposes of the information gathering visit are to obtain information and documentation
needed to support the inspection, to become familiar with the Sequoyah Nuclear Plant fire
protection program, fire protection features, post-fire safe shutdown capabilities, plant layout,
mitigating strategies to address Title 10 of the Code of Federal Regulations (10 CFR) 50.54(hh)
(2); and, as necessary, obtain plant specific site access training and badging for unescorted site
access.
An initial list of the documents the team will review during the conduct of the inspection is listed
in Enclosures 1 and 2. The team leader will contact you with any additional specific document
requests prior to the information gathering visit.
J. Shea 2
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 (including
radiation protection training, security, safety and fitness for duty requirements); and the
availability of knowledgeable plant staff and licensing organization personnel to serve as points
of contact during the inspection.
We request that during the on-site inspection weeks you ensure that copies of analyses,
evaluations or documentation regarding the implementation and maintenance of the station 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 which establish that your fire protection program satisfies NRC regulatory
requirements and conforms to applicable NRC and industry fire protection guidance (i.e., fire
protection compliance assessment documents). For the 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, personnel
should be available at the site during the inspection that is knowledgeable regarding those plant
systems required to achieve and maintain safe shutdown conditions from inside and outside the
control room, including the electrical aspects of the relevant post-fire safe shutdown analyses,
reactor plant fire protection systems and features, and the station 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 NRC Rules and Practices, a copy of this letter and its
enclosures will be available electronically for public inspection in the NRC Public Document
Room or from the Publically 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.hmtl (the Public Electronic Reading Room).
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
J. Shea 3
contact Omar R. López-Santiago, the team leader, in the Region II Office at 404-997-4703 or
me at 404-997-4511.

Triennial Fire Protection Inspection Supporting Documentation
The documents and information requested below should generally be made available to the
inspection team during the on-site information gathering visit for the team's use both on-site and
off-site during the inspection. Electronic format is the preferred media, except where specifically
noted, if readily available (The preferred file format is searchable .pdf files). If electronic media
is made available via an internet based remote document management system, then the remote
document access must allow inspectors to download, save, and print the documents in the
NRC's regional office. Electronic media on compact disc or paper records (hard copy) are
acceptable. At the end of the inspection, the documents in the team's possession will not be
retained.
Approximately three weeks before the on-site information gathering visit, the following
documents should be made available to the team leader for review in the regional office:
- Post-fire Safe Shutdown or Alternative Shutdown Analysis (request A.1)
- Fire Hazards Analysis (request A.2)
- Individual Plant Examination for External Events (Fire Chapter ONLY) (request A.3)
- Plant layout drawings which identify: (C-size paper drawings and electronic
copy)(request B.6)
o Plant fire area boundaries;
o Combustible control zone drawings;
o Areas protected by automatic fire suppression and detection; and
o Locations of fire protection equipment
Based on review of the above three documents, the team leader will identify a preliminary list of
fire areas being considered for inspection prior to the on-site information gathering visit. During
the information gathering visit, or shortly thereafter, the fire areas selected for inspection will be
determined.
This document request is based on typical documents that a generic plant might have. As such,
this generic document request is not meant to imply that any specific plant is required to have all
of the listed documents. It is recognized that some documents listed below may not be
available for your plant. In addition, the document titles listed below are based on typical
