SUBJECT: SEQUOYAH NUCLEAR PLANT - INFORMATION REQUEST FOR THE CYBER-SECURITY
INSPECTION AND NOTIFICATION TO PERFORM INSPECTION 05000327/2020401 and
Dear Mr. Barstow:
On July 20, 2020, the U.S. Nuclear Regulatory Commission (NRC) will begin an inspection in accordance
with Inspection Procedure (IP) 71130.10P Cyber-Security, Revision 0 at Sequoyah Nuclear Plant. The
inspection will be performed to evaluate and verify your ability to meet the Milestone 8 (i.e., full
implementation) requirements of 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 during the weeks of July 20, 2020, and August 3,
2020.
Experience has shown that these types of 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 cyber-security IP. This information should be made available
via secure site (i.e., SharePoint, Certrec) no later than April 27, 2020. The inspection team will review
this information and, by May 25, 2020, 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 CSP selected for the cyber-security inspection. This information will be requested for review
via secure site (i.e., SharePoint, Certrec) before June 24, 2020.
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, July 20, 2020.
J. Barstow 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 Melana Singletary. We understand that our regulatory contact
for this inspection is Mr. Zachary Kitts of your organization. If there are any questions about the
inspection or the material requested, please contact the lead inspector at 404-997-4752 or via e-mail at
Melana.Singletary@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 not 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,
/RA/

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 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 by, April 27, 2020 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 25, 2020, 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 by May 25, 2020.
All requests for information shall follow the guidance document ML17156A215 referenced
above.
The required Table RFI 1 information shall be provided via secure site (i.e., Sharepoint, Certrec)
by April 27, 2020. The preferred file format for all lists is object character recognition (OCR)
readable or a searchable Excel spreadsheet file. These files should be indexed and hyper-linked
