SUBJECT: DONALD. C. COOK NUCLEAR POWER PLANT, UNITS 1 AND 2 - REQUEST FOR INFORMATION FOR AN NRC TRIENNIAL PILOT BASELINE COMPONENT DESIGN BASES INSPECTION (INSPECTION REPORT 05000315/2015008; 05000316/2015008)

Dear Mr. Weber:

On November 2, 2015, the U. S. Nuclear Regulatory Commission (NRC) will begin the team portion of the triennial pilot baseline Component Design Bases Inspection (CDBI) at Donald C. Cook Nuclear Power Plant, Units 1 and 2. This inspection will be performed in accordance with NRC Baseline Inspection Procedure 71111.21T. A team of six inspectors will perform this 2-week onsite pilot inspection. The CDBI focuses on the design, maintenance, and operation of risk-significant components associated with one or more accident scenario or systems. The components to be reviewed during this baseline inspection will be identified during the in-office preparation weeks that occur prior to the first onsite inspection week. In addition, operating experience issues, associated with the component samples, will also be selected for review. The inspection team may request scenarios to be performed on the simulator. This request would require support from your simulator staff to validate scenarios, simulator time, and a crew to perform the actions, which would most likely occur during the second onsite week. The team will work closely with your staff early on during the inspection process to ensure this activity can be accomplished with minimal impact. This pilot inspection will include two weeks onsite. The inspection team will consist of six NRC inspectors, of which five will focus on engineering/maintenance and one on operations. The current inspection schedule is as follows: Preparatory weeks: October 19 -23, 2015; and October 26 - 30, 2015. On-site inspection weeks: November 2 - 6, 2015; and November 16 - 20, 2015. 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: The first group lists information necessary for our initial inspection scoping activities. This information should be provided to the lead inspector no later than September 14, 2015. By September 30, 2015, the lead inspector will communicate the initial selected set of approximately 10 components. The second group of documents requested is those items needed to support our in-office preparation activities. This set of documents, including the calculations associated with the initial selected components, should be provided to the lead inspector at the Regional Office no later than October 14, 2015. 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 November 2, 2015. 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 Féliz-Adorno. We understand that our licensing contact for this inspection is Mr. John Nimtz 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. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390, "Public Inspections, Exemptions, Requests for Withholding," of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC's Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,/RA/ Christine A. Lipa, Chief Engineering Branch 2 Division of Reactor Safety Docket Nos. 50-315; 50-316 License Nos. DPR-58; DPR-74
