SUBJECT: GRAND GULF NUCLEAR STATION - NOTIFICATION OF THE NRC TRIENNIAL FIRE PROTECTION BASELINE INSPECTION (NRC INSPECTION REPORT 05000416/2014007) AND REQUEST FOR INFORMATION
Dear Mr. Mulligan:
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 Grand Gulf Nuclear Station in April and May 2014. 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 NRC's baseline fire protection
inspection procedure.
The schedule for the inspection is as follows:
- Information gathering visit: March 25 - 26, 2014
- Onsite inspection: April 14 - 18, 2014 April 28 - May 2, 2014
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 the 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 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 UNITED STATESNUCLEAR REGULATORY COMMISSIONREGION IV1600 EAST LAMAR BLVDARLINGTON, TEXAS 76011-4511
K. Mulligan - 2 -
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
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 establishing 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 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 Offi
ce 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
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).
