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

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
