SUBJECT: BYRON STATION, UNITS 1 AND 2INFORMATION REQUEST FOR THE
CYBER-SECURITY FULL IMPLEMENTATION INSPECTION, NOTIFICATION
TO PERFORM INSPECTION 05000454/2018410; 05000455/2018410
Dear Mr. Hanson:
On May 21, 2018, the U.S. Nuclear Regulatory Commission (NRC) will begin an inspection in
accordance with Inspection Procedure 71130.10P Cyber-Security, issued May 15, 2017, at
your Byron Station, Units 1 and 2. The inspection will be performed to evaluate and verify your
ability to meet full implementation requirements of the NRCs Cyber-Security Rule, Title 10 of
the Code of Federal Regulations, 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 May 21, 2018, and June 4, 2018.
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. 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 Inspection
Procedure. This information should be made available via compact disc and delivered to
the regional office no later than February 26, 2018. The inspection team will review this
information and, by March 26, 2018, 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, defensive architecture,
and the areas of your plants Cyber-Security Program selected for the Cyber-Security
Inspection. This information will be requested for review in the regional office prior to the
inspection by April 23, 2018.
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, May 21, 2018.
B. Hanson -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 Mr. Dariusz Szwarc. We understand that our regulatory
contact for this inspection is Ms. Zoe Cox of your organization. If there are any questions about
the inspection or the material requested, please contact the lead inspector at 630-829-9803 or
via e-mail at Dariusz.Szwarc@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.
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 Request for Information (RFI)) concentrates
on providing the inspection team with the general information necessary to select
appropriate components and Cyber-Security Program (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 security control
portions of the CSP to be chosen as the sample set required to be inspected by the
Cyber-Security Inspection Procedure. 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 February 26, 2018, or sooner, to facilitate the selection of the specific
items that will be reviewed during the onsite inspection weeks.
Enclosure
DOCUMENT REQUEST FOR CYBER-SECURITY INSPECTION
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 March 26, 2018, 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. All requests for this information shall follow the Table RFI #1
and the guidance document referenced above.
The required Table RFI #1 information shall be provided on compact disc (CD) to the
lead inspector by February 26, 2018. Please provide five copies of each CD submitted
