SUBJECT: DAVIS-BESSE NUCLEAR POWER STATION - INFORMATION REQUEST FOR

THE CYBER-SECURITY BASELINE INSPECTION, NOTIFICATION TO

PERFORM INSPECTION 05000346/2023402

Dear Terry Brown:

On November 6, 2023, the U.S. Nuclear Regulatory Commission (NRC) will begin a baseline

inspection in accordance with Inspection Procedure (IP) 71130.10 Cyber-Security, Revision 0

at your Davis-Besse Nuclear Power Station. The inspection will be performed to evaluate and

verify your ability to meet the NRCs Cyber-Security Rule, Title 10, Code of Federal Regulations

(CFR), Part 73, Section 54, Protection of Digital Computer and Communication Systems and

Networks. The onsite portion of the inspection will take place November 6-10, 2023.

Experience has shown that baseline inspections 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 for both parties, we have enclosed a request for

documents needed for the inspection. These documents have been divided into four groups.

The first group specifies information necessary to assist the inspection team in choosing the

focus areas (i.e., sample set) to be inspected by the cyber-security IP. This information should

be made available electronically no later than September 12, 2023. The inspection team will

review this information and, by September 25, 2023, will request the specific items that should

be provided for review.

The second group of additional requested documents will assist the inspection team in the

evaluation of the critical systems and critical digital assets (CSs/CDAs), defensive architecture,

and the areas of the licensees Cyber Security Plan (CSP) selected for the cyber-security

inspection. This information will be requested for review in the regional office prior to the

inspection by October 25, 2023, as identified above.

The third group of requested documents consists of those items that the inspection team will

review, or need access to, during the inspection. Please have this information available by the

first day of the onsite inspection, November 6, 2023.

T. Brown -2-

The fourth group of information is 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 complete in order to minimize the number of additional

documents requested during the preparation and/or the onsite portions of the inspection.

The lead inspector for this inspection is Jasmine Gilliam. We understand that our regulatory

contact for this inspection is Gerald Wolf of your organization. If there are any questions about

the inspection or the material requested, please contact the lead inspector at 630-829-9831 or

via e-mail at Jasmine.Gilliam@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, Public Inspections, Exemptions, Requests for Withholding,

of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available

electronically for public inspection in the NRCs Public Document Room or from the Publicly

Available Records (PARS) component of the NRC's Agencywide Documents Access and

Management 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,

Signed by Gilliam, Jasmine

I. Information Requested for In-Office Preparation

The initial request for information (i.e., first RFI) concentrates on providing the inspection

team with the general information necessary to select appropriate components and

Cyber Security Plan (CSP) elements to develop a site-specific inspection plan. The first

RFI is used to identify the list of critical systems and critical digital assets (CSs/CDAs)

plus operational and management (O&M) security control portions of the CSP to be

chosen as the sample set required to be inspected by the cyber-security IP. The first

RFIs requested information is specified below in Table RFI #1. The Table RFI #1

information is requested to be provided to the regional office by September 12, 2023, or

sooner, to facilitate the selection of the specific items that will be reviewed during the

onsite inspection weeks.

The inspection team will examine the returned documentation from the first RFI and

identify/select specific systems and equipment (e.g., CSs/CDAs) to provide a more

focused follow-up request to develop the second RFI. The inspection team will submit

the specific systems and equipment list to your staff by September 25, 2023, which will

identify the specific systems and equipment that will be utilized to evaluate the

CSs/CDAs, defensive architecture, and the areas of the licensees CSP selected for the

cyber-security inspection. We request that the additional information provided from the

second RFI be made available to the regional office prior to the inspection by

October 25, 2023.

The required Table RFI 1 information shall be provided electronically to the lead

inspector by September 12, 2023. If a compact disk (CD) is provided, please provide

four copies (one for each inspector/contactor). The preferred file format for all lists is a

searchable Excel spreadsheet file. These files should be indexed and hyper-linked to

facilitate ease of use. If you have any questions regarding this information, please call

the inspection team leader as soon as possible.
