SUBJECT: BRAIDWOOD STATION, UNITS 1 AND 2INFORMATION REQUEST FOR THE

CYBER-SECURITY FULL IMPLEMENTATION INSPECTION, NOTIFICATION

TO PERFORM INSPECTION 05000456/2019410; 05000457/2019410

Dear Hanson:

On February 11, 2019, 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 Braidwood 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 February 11, 2019, and February 25, 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. 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 November 19, 2018. The inspection team will review

this information and, by December 17, 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 January 14, 2019.

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, February 11, 2019.

B. Hanson

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 Mr. Richard Schliessmann 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 Title 10 of the Code of Federal Regulations, Part 2.390, Public Inspections,

Exemptions, Requests for Withholding.

Sincerely,

/RA/

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 (O&M) security

control portions of the CSP to be chosen as the sample set required to be inspected by

the Cyber-Security Inspection Procedure (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 November 19, 2018, 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 December 17, 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.

searchable Excel spreadsheet file. These CDs should be indexed and hyper-linked to

facilitate ease of use. If you have any questions regarding this information, please call
