SUBJECT: OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 - NOTIFICATION OF

CONDUCT OF A TRIENNIAL FIRE PROTECTION BASELINE INSPECTION-

U. S. NUCLEAR REGULATORY COMMISSION INSPECTION REPORT

NOS. 05000269/2016007, 05000270/2016007, AND 05000287/2016007

Dear Mr. Batson:

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 the Oconee Nuclear Station,

Units 1, 2, and 3, in February and March 2016. The inspection will be conducted in accordance

with IP 71111.05XT, the NRCs baseline fire protection inspection procedure for plants that have

transitioned their fire protection program to meet the requirements of 10 CFR 50.48(c). The

inspection will also review the status of the Milestone 6 Item and related information from the

NRC Notice of Violation and Confirmatory Order dated July 1, 2013 (ML13114A928). The

inspection team will be led by Jonathan Montgomery, a Senior Reactor Inspector from the NRC

Region II Office. The team will be composed of personnel from the Region II Office.

On December 1, 2015, during a telephone conversation between Judy Smith of your staff and

Mr. Montgomery, 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:

February 16-18, 2016

Week 1 of onsite inspection: February 29-March 4, 2016

Week 2 of onsite inspection: March 14-18, 2016

The purposes of the information gathering visit are to obtain information and documentation

needed to support the inspection, to become familiar with the Oconee Nuclear Station 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.

S. Batson

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. Montgomery at (404) 997-4880 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 Oconee 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 Oconee 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/reading-

rm/adams.html (the Public Electronic Reading Room).

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)

NFPA 805 Transition Report, developed in accordance with NEI 04-02 (request A.4)

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)

Based on review of the above seven documents, 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.
