DONALD C. COOK NUCLEAR POWER PLANT NOTIFICATION OF AN NRC TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION (CDBI) AND REQUEST FOR INFORMATION

Dear Mr. Weber:

On July 23, 2012, the U.S. Nuclear Regulatory Commission (NRC) will begin a triennial baseline Component Design Bases Inspection (CDBI) at your Donald C. Cook Nuclear Power Plant. A team of six inspectors will perform this 3-week inspection. This inspection will be performed in accordance with NRC baseline inspection procedure (IP) 71111.21. The CDBI focuses on the design, maintenance, and operation of risk significant components associated with one, or more accident scenarios. The components to be reviewed during this baseline inspection will be identified during the in-office preparation week that occurs prior to the first on-site inspection week. In addition, operating experience issues, associated with the component samples, will also be selected for review. The inspection will include three weeks on-site. 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:

• On-site weeks: July 23 - 27, 2012; August 6 - 10, 2012; and August 20 - 24, 2012. The team will be preparing for the inspection, mainly during the week of July 9, 2012, as discussed in the enclosure. A Region III Senior Reactor Analyst may accompany the inspection

team during the week of July 23, 2012, to review probabilistic risk-assessment data, and assist in identifying risk significant components and/or specific component functions, which will be reviewed during the inspection. Experience with previous baseline design insp ections of similar depth and length has shown that this type of inspection is extremely resour ce 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.

L. Weber 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 on-site 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 April 6, 2012. By April 27, 2012, the lead inspector will communicate the initial selected set of approximately 25 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 July 9, 2012. During the in-office preparation activities, the team may identify additional information needed to support the inspection.

• The last group includes the additional information mentioned above, as well as plant specific reference material. This information should be available to the team on-site on July 23, 2012. 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 Caroline Tilton. We understand that our licensing contact for this inspection is Mr. Kevin Mitchell 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) 829-9718 or via e-mail at caroline.tilton@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 current valid Office of Management and Budget control number.

L. Weber In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/
