UNITED STATES NUCLEAR REGULATORY COMMISSION REGION III 2443 WARRENVILLE RD. SUITE 210 LISLE, ILLINOIS 60532-4352 November 21, 2017 Mr. Dean Curtland Director of Site Operations NextEra Energy Duane Arnold, LLC 3277 DAEC Road Palo, IA 523249785 SUBJECT: DUANE ARNOLD ENERGY CENTERREQUEST FOR INFORMATION FOR AN NRC DESIGN BASES ASSURANCE INSPECTION (PROGRAM): IMPLEMENTATION OF THE ENVIRONMENTAL QUALIFICATION PROGRAM; INSPECTION REPORT 05000331/2018010 Dear Mr. Curtland: On April 23, 2018, the U. S. Nuclear Regulatory Commission (NRC) will begin a triennial baseline Design Bases Assurance Inspection (Program) at the Duane Arnold Energy Center. This inspection will be performed in accordance with NRC Baseline Inspection Procedure 71111.21N, Attachment 1. The Design Bases Assurance Inspection will focus on the implementation of the electrical equipment Environmental Qualification (EQ) Program to verify you are maintaining the qualified status of equipment during the life of the plant. The EQ components to be reviewed during this baseline inspection will be identified during the in-office preparation week that occurs prior to the onsite inspection week. The inspection will include a bagman trip to support selection of components and 2 weeks of onsite inspection. The inspection team will consist of 3 NRC inspectors. The current inspection schedule is as follows: Bagman trip onsite week: February 19, 2018 Team preparation week: April 1620, 2018 Onsite inspection weeks: April 2327, 2018, and May 711, 2018. Experience with previous baseline design inspections of similar depth and length has shown that this type of inspection is 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 information needed for 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. Insofar as possible, this information should be provided electronically to the lead inspector. The information request has been divided into four groups:

D. Curtland -2- The first group lists information necessary for our initial inspection scoping activities. This information should be provided to the lead inspector no later than January 5, 2018. Prior to the bagman trip on January 19, 2018, the lead inspector will communicate the initial selected set of approximately 12 EQ components. The second group of documents requested is those items needed to support the bagman trip. This set of documents should be available to the lead inspector onsite on February 19, 2018. The third group of documents requested is those items needed to support our in-office preparation activities for the selected set of 69 EQ components. This set of documents should be provided to the lead inspector at the Regional Office no later than April 5, 2018. During the in-office preparation activities, the team may identify additional information needed to support the inspection. The last group includes the additional information above as well as plant specific reference material. This information should be available to the team onsite on April 23, 2018. It is also requested that corrective action documents and/or questions developed during the inspection be provided to the lead inspector as the documents are generated. The lead inspector for this inspection is Mr. Néstor J. Féliz Adorno. We understand that our licensing contact for this inspection is Mr. B. Murrell of your organization. If there are any questions about the inspection or the material requested in the enclosure, please contact the lead inspector at (630) 829-9739 or via e-mail at Nestor.Feliz-Adorno@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 Sincerely, /RA Michael Jones Acting for/ Néstor J.
