SUBJECT: MCGUIRE NUCLEAR STATION - INFORMATION REQUEST FOR THE

CYBERSECURITY BASELINE INSPECTION, NOTIFICATION TO PERFORM

INSPECTION 05000369/2024403; 05000370/2024403

Dear Edward Pigott:

On June 24, 2024, the U.S. Nuclear Regulatory Commission (NRC) will begin a baseline

inspection in accordance with Inspection Procedure (IP) 71130.10 Cybersecurity, Revision 0 at

your McGuire Nuclear Station. The inspection will be performed to evaluate and verify your

ability to provide assurance that your digital computer and communication systems and

networks associated with safety, security, or emergency preparedness (SSEP) functions are

adequately protected against cyber-attacks in accordance with Title 10 of the Code of Federal

Regulations (10 CFR) 73.54 and the U.S. Nuclear Regulatory Commission (NRC) approved

cyber security plan (CSP). The onsite portion of the inspection will take place during the week of

June 24, 2024.

Experience has shown that baseline inspections are extremely resource intensive, both for the

NRC inspectors and the licensee staff. 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 cybersecurity IP. This information should

be made available electronically no later than May 10, 2024. The inspection team will review

this information and, by May 17, 2024, will request the specific items that should be provided for

review. This 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 CSP selected for the cybersecurity inspection. We

request that the information provided from the second RFI be made available to the regional

office prior to the inspection by June 14, 2024.

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, June 24, 2024.

April 10, 2024

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 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 Philipp Braaten. We understand that our regulatory

contact for this inspection is Jeff Thomas of your organization. If there are any questions about

the inspection or the material requested, please contact the lead inspector at (404) 997-4651 or

via e-mail at Philipp.braaten@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).

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 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 cybersecurity 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 May

10, 2024, 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 May 17, 2024, 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 cybersecurity inspection. We request that

the additional information provided from the second RFI be made available to the regional

office prior to the inspection by June 14, 2024. All requests for information shall follow the

guidance document U.S. NRC - Guidance Document for Development of the Request for

Information (RFI) and Notification Letter for Full Implementation of the Cyber Security

Inspection, referenced above.

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

May 10, 2024. The preferred file format for all lists is a searchable Excel spreadsheet file. The

information 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.
