SUBJECT:
RIVER BEND STATION, UNIT 1 - NOTIFICATION OF NRC DESIGN BASES
ASSURANCE INSPECTION (PROGRAMS) (05000458/2019012) AND INITIAL
REQUEST FOR INFORMATION
Dear Mr. Vercelli:
On July 15, 2019, the Nuclear Regulatory Commission (NRC) will begin an inspection at the
River Bend Station, Unit 1. A three-person team will perform this inspection using NRC
Inspection Procedure 71111.21N, Design Bases Inspection (Programs), Attachment 1,
Environmental Qualification under 10 CFR 50.49 Programs, Processes, and Procedures.
This inspection will evaluate the implementation of the environmental qualification of electrical
equipment program, as required by the River Bend Station, Unit 1 Operating License.
Additionally, the team will perform an inspection of the equipment qualification documentation
files to verify that electrical equipment important to safety meets the requirements of
10 CFR 50.49. The team will select components that will be subjected to harsh environments
and required to mitigate the consequences of a design basis accident.
The inspection will include an information gathering site visit by the team leader and 2 weeks of
onsite inspection by the team. The inspection will consist of three NRC inspectors. The current
inspection schedule is as follows:
Onsite Information Gathering Visit: June 24 - 28, 2019
Preparation Weeks: July 8 - 12, 2019, and July 22 - 26, 2019
Onsite Weeks: July 15 - 19, 2019, and July 29 - August 2, 2019
The purpose of the information gathering visit is to meet with members of your staff to become
familiar with the River Bend Station, Unit 1 environmental qualification program. The lead
inspector will request a meeting with your personnel to discuss the site environmental
qualification program and procedures. Additionally, the lead inspector will request a discussion
with your staff to become familiar with the equipment qualification regulations and standards to
which the site is committed. Additional information and documentation needed to support the
inspection will be identified during the inspection, including interviews with engineering
managers and engineers.
Our experience with these inspections has shown that they are 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
S. Vercelli

the inspection. This information should be made available to the lead inspector during the
June 24 - 28, 2019, visit. Since the inspection will be concentrated on the environmental
qualification of the equipment, the equipment qualification master list (EQML) should be
available to review during the information gathering visit to assist in our selection of
components.
It is requested that this information be provided to the lead inspector as the information is
generated during the inspection. Additional requests by inspectors will be made during the
onsite week for specific documents needed to complete the review of that component/selection.
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 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 Ronald A. Kopriva. We understand that our licensing
engineer contact for this inspection is Ms. Bridget Johns. If there are any questions about
the inspection or the requested materials, please contact the lead inspector by telephone
at 817-200-1104 or by e-mail at Ron.Kopriva@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 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).

Information Requested for Information Gathering Visit (June 24, 2019)
The following information should be provided to the lead inspector in hard copy or
electronic format, to the attention of Ronald Kopriva by June 17, 2019, to facilitate the
reduction in the items to be selected for a final list of components. The inspection team
will finalize the selected list during the prep week using the documents requested in this
enclosure. The specific items selected from the lists shall be available and ready for
review on the day indicated in this request. *Please provide requested documentation
electronically in pdf files, Excel, or other searchable formats, if possible. The
information should contain descriptive names and be indexed and hyperlinked to
facilitate ease of use. Information in "lists" should contain enough information to be
easily understood by someone who has knowledge of boiling water reactor technology.
If requested documents are large and only hard copy formats are available, please
inform the inspectors, and provide subject documentation during the first day of the
onsite inspection.
