PRAIRIE ISLAND NUCLEAR GENERATING PLANT, UNITS 1 AND 2REQUEST FOR INFORMATION FOR AN NRC DESIGN BASES ASSURANCE INSPECTION (PROGRAM): IMPLEMENTATION OF THE ENVIRONMENTAL QUALIFICATION PROGRAM; INSPECTION REPORT 05000282/2019011 AND 05000306/2019011

Dear Mr. Sharp:

On January 28, 2019, the U. S. Nuclear Regulatory Commission (NRC) will begin a triennial baseline Design Bases Assurance Inspection (Program) at Prairie Island Nuclear Generating Plant. 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 inoffice preparation week that occurs prior to the onsite inspection week.

The inspection will include two weeks of onsite inspection. The inspection team will consist of three NRC inspectors. The current inspection schedule is as follows:

• Preparation week: January 21-25, 2019;

• Onsite inspection weeks: January 28, 2019, through February 1, 2019; and February 11-15, 2019.

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 three groups:

S. Sharp

• The first group lists information necessary for our initial inspection scoping activities. This information should be provided to the lead inspector no later than November 27, 2018. By November 29, 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 our in-office preparation activities for the selected set of 9-12 EQ components. This set of documents should be provided to the lead inspector at the Regional Office no later than January 11, 2019. 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 January 28, 2019. 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. Benny Jose. We understand that our licensing contact for this inspection is Mr. Bryan Dixon of your organization. If there are any questions about the inspection or the material requested in the enclosure, please contact the lead inspector at 630-829-9756 or via e-mail at Benny.Jose@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 Reguations, Part 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

Benny Jose, Senior Reactor Engineer Engineering Branch 2 Division of Reactor Safety Docket Nos. 50-282; 50-306 License Nos. DPR-42; DPR-60

Information Requested for Initial Inspection Scoping Activities The following information is requested by November 27, 2018, or sooner, to facilitate inspection preparation. If you have any questions regarding this information, please call the team leader as soon as possible. (Please provide the information electronically in pdf files, Excel, or other searchable formats, preferably on some portable electronic media (e.g., CD-ROM, DVD, etc.). The portable electronic media should contain descriptive names, and be indexed and hyperlinked to facilitate ease of use. Information in lists should contain enough information to be easily understood by someone who has knowledge of light water reactor technology).
