SUBJECT: GRAND GULF NUCLEAR STATION - NOTIFICATION OF NRC DESIGN BASES ASSURANCE INSPECTION (05000416/2017007)
AND INITIAL REQUEST FOR INFORMATION
Dear Mr. Larson:
On August 22, 2017, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial
baseline Design Bases Assurance Inspection at the Grand Gulf Nuclear Station. A six-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
four NRC inspectors and two contractors, of which five
will focus on engineering and one on operations. The current inspection schedule is as follows:
On-site Information Gathering Visit: August 22-24, 2017
Preparation Week: August 28-September 1, 2017
On-site Weeks: September 11-15 and September 25-29, 2017.
The purpose of the information gathering visit is to meet with members of your staff and 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.
UNITED STATES NUCLEAR REGULATORY COMMISSION REGION IV 1600 E. LAMAR BLVD ARLINGTON, TX 76011-4511
E. Larson 2 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 August 14, 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 Mr. S. Du Pont.
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

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 will be
