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 2

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).

I. 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.
