SUBJECT: GRAND GULF NUCLEAR STATION - INFORMATION REQUEST FOR NRC

TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION NRC

INSPECTION REPORT 05000416/2009006

Dear Mr. Douet:

On February 2, 2009, the NRC will begin a triennial baseline Component Design Bases

Inspection at the Grand Gulf Nuclear Station. A seven-person team will perform this inspection

using NRC Inspection Procedure 71111.21, Component Design Bases Inspection.

The inspection focuses on components and operator actions that have high risk and low design

margins. The samples reviewed during this inspection will be identified during an information

gathering visit and during the subsequent in-office preparation week. In addition, a number of

operating experience issues will also be selected for review.

The inspection will include an information gathering site visit by the team leader and a senior

reactor analyst, and 3-weeks of onsite inspection by the team. The inspection will consist of

seven NRC inspectors, of which six will focus on engineering and one on operations. The

current inspection schedule is as follows:

Onsite information gathering visit: Week of January 19, 2009

Onsite weeks: February 2, February 16, and February 23, 2009

The purpose of the information gathering visit is to meet with members of your staff to identify

potential risk-significant components and operator actions. The lead inspector will also request

a tour of the plant with members of your operations staff and probabilistic safety assessment

staff. Additional information and documentation needed to support the inspection will be

identified, including interviews with engineering managers, engineers, and probabilistic safety

assessment staff.

Our experience with these inspections has shown they are extremely resource intensive, both

for the NRC inspectors and the licensee staff. In order to minimize the inspection impact on the

site and to ensure a productive inspection, we have enclosed a request for information needed

for the inspection. The request has been divided into three groups. The first group lists

information necessary for the information gathering visit and for general preparation. This

Entergy Operations, Inc. -2-

information should be available to the regional office no later than January 27, 2009. Insofar as

possible, this information should be provided electronically to the lead inspector. Since the

inspection will be concentrated on high risk/low margin components, calculations associated

with your list of high risk components should be available to review during the information

gathering visit to assist in our selection of components based on available design margin.

The second group of documents requested are those items that the team will need access to

when onsite and after the inspection samples are selected. The third group lists information

necessary to aid the inspection team in tracking issues identified as a result of the inspection. It

is requested that this information be provided to the lead inspector as the information is

generated during the inspection. It is important that all of these documents are up to date and

completed in order to minimize the number of additional documents requested during the

preparation and/or the onsite portions of the inspection. In order to facilitate the inspection, we

request that a contact individual be assigned to each inspector to ensure information requests,

questions, and concerns are addressed in a timely manner.

The lead inspector for this inspection is Mr. Ronald A. Kopriva. We understand that our

licensing engineer contact for this inspection is Mr. Dennis Coulter. If there are any questions

about the inspection or the requested materials, please contact the lead inspector at (817) 860-

8104 or via e-mail at ron.kopriva@nrc.gov.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be

made 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).

Sincerely,

/RA/
