SUBJECT: ARKANSAS NUCLEAR ONE, UNITS 1 AND 2 - NOTIFICATION OF CYBER-SECURITY INSPECTION (NRC INSPECTION REPORT 05000313/2018405 AND 05000368/2018405) AND REQUEST FOR INFORMATION

Dear Mr. Anderson:

On July 23, 2018, the U.S. Nuclear Regulatory Commission (NRC) will begin an inspection in accordance with Inspection Procedure (IP) 71130.10P, "Cyber-Security," Revision 0, at Arkansas Nuclear One, Units 1 and 2. This inspection evaluates and verifies your ability to meet the full implementation requirements of the NRC's 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 23, 2018, and August 6, 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. 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 either IMS/CERTREC (preferred) or passive media (i.e. CD, DVD) and delivered to the regional office no later than April 30, 2018. The inspection team will review this information and by the end of the planned information gathering visit on June 28, 2018, will request 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 July 9, 2018, as identified above. 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, July 23, 2018. 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 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 Sam Graves. We understand that our regulatory contact for this inspection is Natalie Mosher. If there are any questions about the inspection or the material requested, please contact the lead inspector at 817-200-1102, or by e-mail at samuel.graves@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,/RA/ Gregory E. Werner, Chief Engineering Branch 2 Division of Reactor Safety Dockets: 50-313; 50-368 Licenses: DPR-51; NPF-6

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 (O&M) 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. Provide the first set of information to the team leader in the regional office by April 30, 2018, or sooner, to facilitate the selection of the specific items that will be reviewed during the onsite inspection weeks. The 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 for information to develop the second RFI. The inspection team will submit the specific systems and equipment list to your staff by the end of the planned information gathering visit on June 28, 2018, which will identify the specific systems and equipment that will be utilized to evaluate the critical systems and critical digital assets, defensive architecture, and the areas of the cyber-security program selected for the cyber-security inspection. We request that the additional information provided from the second RFI be made available to the regional office prior to the inspection by July 9, 2018. All requests for information shall follow the guidance in Reference 1.
