SUBJECT: GRAND GULF NUCLEAR STATION, UNIT 1 - NOTIFICATION OF
CYBER SECURITY INSPECTION (05000416/2019410) AND
REQUEST FOR INFORMATION
Dear Mr. Larson:
On April 29, 2019, the U.S. Nuclear Regulatory Commission (NRC) will begin an inspection in
accordance with Inspection Procedure (IP) 71130.10P, Cyber Security, Revision 0, at the
Grand Gulf Nuclear Station. This inspection evaluates and verifies your ability to meet the 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 April 29 and May 13, 2019.
Experience has shown that these 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. The document request has been divided into
four groups. The first group specifies information necessary to assist the team in choosing
the focus areas (i.e., sample set) to be inspected in accordance with the cyber security
inspection procedure. This information should be made available using passive media
(i.e. CD, DVD) and delivered to the regional office no later than March 1, 2019. The inspection
team will review this information and by the end of the planned information gathering visit,
March 21, 2019, will identify the specific items that should be provided for review.
The second group of requested documents will assist the team in their evaluation of the
critical systems and critical digital assets, defensive architecture, and the areas of the cyber
security plan selected for inspection. This information will be requested for review in the
regional office prior to the inspection by April 5, 2019.
The third group of requested documents consists of those items that the team will review or
need access to, during the inspection. Please have this information available by the first day of
the onsite inspection, April 29, 2019.
The fourth group of information is necessary to aid the 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
E. Larson 2
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 Nnaerika Okonkwo. We understand that our regulatory
contact for this inspection is Sheryl Sweet. If there are any questions about the inspection or
the material requested, please contact the lead inspector at 817-200-1114 or by e-mail at
Nnaerika.Okonkwo@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 under 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.
This letter and its enclosure will be made available for public inspection and copying at
http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in
accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.
Sincerely,

I. Information Requested for In-Office Preparation
The initial request for information (i.e., first RFI) provides the team with the general
information necessary to select appropriate components and cyber security plan elements
to develop a site-specific inspection plan. The team will use the first set of information
requested to identify the list of critical systems and critical digital assets plus operational
and management security control portions of the Cyber Security Plan to be chosen as the
sample set required to be inspected during this inspection. The first information request
is specified in Table RFI #1.
The required Table RFI #1 information shall be provided on passive media (i.e. CD or DVD)
to the lead inspector by March 1, 2019, or sooner to facilitate the selection of the specific
items that will be reviewed during the onsite inspection weeks. Please provide four copies
of each media submitted (i.e., one for each inspector/contractor). The preferred file format
for all lists is a searchable Excel spreadsheet file on a CD or DVD. The files should be
indexed and hyperlinked to facilitate efficient review. If you have any questions regarding
this information, please contact the inspection team lead as soon as possible.
