River Bend Station

5485 U.S. Highway 61N

St. Francisville, LA 70775

SUBJECT: RIVER BEND STATION - NOTIFICATION OF AN NRC TRIENNIAL

FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION

REPORT 05000458/2019010) AND REQUEST FOR INFORMATION

Dear Mr. Vercelli:

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 River Bend

Station in October and November 2019. 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: October 1 - 2, 2019
  • Onsite inspection: October 21 - 25, 2019

November 4 - 8, 2019

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 leader 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 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 leader will also discuss the following inspection

support administrative details: office space size and location, specific documents requested to

S. Vercelli 2

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 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.

This letter and its enclosure will be made available for public inspection and copying at

http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in

accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

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 John.Mateychick@nrc.gov.

Sincerely,

/RA Gregory Pick Acting for/
