SUBJECT: WATTS BAR NUCLEAR PLANT - NOTIFICATION OF CONDUCT OF A
TRIENNIAL FIRE PROTECTION BASELINE INSPECTION - U.S. NUCLEAR
REGULATORY COMMISSION INSPECTION REPORT NOS.
05000390/2018011 AND 05000391/2018011
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 your Watts Bar Nuclear Plant,
Units 1 and 2, in November 2018. The inspection will be conducted in accordance with IP 71111.05T, dated January 31, 2013, the NRCs baseline fire protection inspection procedure for
plants that have transitioned their fire protection program to meet the requirements of Title
10 of the Code of Federal Regulations (10 CFR) 50.48(c). The inspection team will be led by
Mr. Larry J. Jones Jr., a Senior Reactor Inspector from the NRC Region II Office. The team will
be composed of personnel from the Region II Office.
On July 3, 2018, during communications between Mr. Dean Baker and Mr. Jones, our
respective staffs confirmed arrangements for a three-day information gathering onsite visit and a
two-week onsite fire protection inspection. The schedule for the inspection is as follows:
- Information gathering visit: September 17, 2018
- Week 1 of onsite inspection: November 5-9, 2018
- Week 2 of onsite inspection: November 26-30, 2018
The purposes of the information gathering visit are to obtain information and documentation
needed to support the inspection, to become familiar with the Watts Bar Nuclear Plants fire
protection program, fire protection features, post-fire safe shutdown capabilities, plant layout,
mitigating strategies to address 10 CFR 50.54(hh)(2), and, as necessary, obtain plant specific
site access training and badging for unescorted site access.
J. Shea 2
The types of documents the team will be reviewing during conduct of the inspection are listed in
Enclosures 1 and 2. Please contact Mr. Jones at (404) 997-4837 prior to preparing copies of
the materials listed in the Enclosures. The inspection team will try to minimize your
administrative burden by specifically identifying those documents required for inspection
preparation.
During the information gathering visit, the team will also discuss the following inspection support
administrative details: office space; specific documents to be made available to the team in their
office space; arrangements for unescorted site access (including, as necessary, radiation
protection training, security, safety and fitness for duty requirements); 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 Watts Bar
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 who are 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 Watts Bar 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's "Rules of Practice," a copy of this letter and its
enclosures will be 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/
readingrm/adams.html (the Public Electronic Reading Room).
J. Shea 3
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 Mr. Jones, the team leader, in the Region II Office at (404) 997-4837, or me at
(404) 997-4521.
Sincerely,

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 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 Nuclear Safety Capability, Systems, and Separation Analysis (request A.1)
- Fire Hazards Analysis and/or NFPA 805 Design Basis Document (request A.2)
- Fire Probabilistic Risk Assessment (PRA) Summary Document or full PRA Document
(request A.3)
- Fire Risk Evaluations (i.e., NFPA 805 Section 2.4.3) (request A.5)
- Plant Change Evaluations (i.e., NFPA 805 Section 2.4.4) (request A.6)
- Analysis that demonstrates nuclear safety performance criteria can be achieved and
maintained for those areas that require recovery actions (request A.7)
- List of the top 25 highest CDF scenarios for each unit
- List of the top 25 highest LERF scenarios for each unit
- Status of committed modifications and implementation items listed in Attachment S of
the NFPA 805 Transition Report
Based on review of the above ten documents, the team leader should 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
industry document names; your plant specific document titles may vary.
