NUCLEAR REGULATORY COMMISSION
REGION IV
1600 E. LAMAR BLVD
ARLINGTON, TX 76011-4511
February 27, 2017
Mr. William F. Maguire
Site Vice President
Entergy Operations, Inc.
River Bend Station
5485 US Highway 61N
St. Francisville, LA 70775
SUBJECT: RIVER BEND STATION - NOTIFICATION OF NRC DESIGN BASES
ASSURANCE INSPECTION (05000458/2017007) AND INITIAL REQUEST
FOR INFORMATION
Dear Mr. Maguire:
On May 30, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial
baseline Design Bases Assurance Inspection at the River Bend Station. A seven-person team
will perform this inspection using NRC Inspection Procedure 71111.21M, Design Bases
Assurance Inspection.
The inspection focuses on components, modifications, 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 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 two weeks of on-site inspection by the team. The inspection will consist of
five NRC inspectors and two contractors, of which six will focus on engineering and one on
operations. The current inspection schedule is as follows:
On-site Information Gathering Visit: May 30-June 1, 2017
Preparation Week: June 5-9, 2017
On-site Weeks: June 12-16 and June 26-30, 2017.
The purpose of the information gathering visit is to meet with members of your staff to identify
potential risk-significant components, modifications, 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. During the on-site weeks, several days of time will be needed on the
plant-referenced simulator in order to facilitate the development of operator action-based
scenarios. Additional information and documentation needed to support the inspection will be
identified during the inspection, including interviews with engineering managers, engineers, and
probabilistic safety assessment staff.

Our experience with these inspections has shown that 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 two groups. The first group lists
information necessary for the information gathering visit and for general preparation. This
information should be available to the regional office no later than May 15, 2017. 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 and modifications,
calculations associated with your list of high risk components and modifications 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, 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. An additional request will be made by the team during the preparation week once
the specific components and modifications have been selected. Additional requests by
inspectors will also be made throughout the on-site weeks for specific documents needed to
complete the review. It is important that all of these documents are up to date and complete in
order to minimize the number of additional documents requested during the preparation and/or
on-site 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 Wayne Sifre. We understand that our licensing
engineer contact for this inspection is Ms. K. Huffstatler. If there are any questions about the
inspection or the requested materials, please contact the lead inspector by telephone at
817-200-1193 or by e-mail at Wayne.Sifre@nrc.gov.
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, 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 NRCs 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).

I. Information Requested Prior to Information Gathering Visit (May 30, 2017)
The following information (Section I of this enclosure) should be sent to the Region IV
office in hard copy or electronic format (Certrec IMS preferred), to the attention of Wayne
