SUBJECT:
D.C. COOK NUCLEAR POWER PLANT, UNITS 1 AND 2, INFORMATION REQUEST FOR AN NRC BIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION (CDBI) 05000315/2007002(DRS); 316/2007002(DRS)
Dear Mr. Nazar:
On January 29, 2007, the NRC will begin a biennial baseline Component Design Bases Inspection (CDBI) at the D.C. Cook Nuclear Power Plant. A team of six inspectors will perform this 3-week onsite inspection. This inspection will be performed in accordance with revised NRC Baseline Inspection Procedure (IP) 71111.21 and replaces the biennial Safety System Design and Performance Capability inspection.
The CDBI inspection focuses on components which have high risk and low design margins.
The components to be reviewed during this baseline inspection will be identified during an in-office preparation week, prior to the first week of on-site inspection. In addition, a number of risk significant operator actions and operating experience issues, associated with the component samples, will also be selected for review.
The inspection will include one week of in-office preparation/information gathering and three weeks of on-site inspection. The inspection team will consist of six NRC inspectors, of which five will focus on engineering and one on operations. The current inspection schedule is as follows:
On-site weeks: January 29, February 12, and February 26, 2007.
The team will be preparing for the inspection mainly during the week of January 22, 2007, as discussed in the attached enclosure. A Region III Senior Reactor Analyst will accompany the inspection team during the week of January 29, 2007, to review probabilistic risk assessment data and assist in identifying risk significant components, which will be reviewed during the inspection.
Experience with previous baseline design inspections of similar depth and length has shown that these type of 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 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 on-site portions of M. Nazar 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 available to the lead inspector no later than January 2, 2007. By January 8, 2007, the lead inspector will communicate the initial selected set of approximately 30 high risk components.
The second group of documents requested are those items needed to support our in-office preparation activities. This set of documents, including the calculations (please provide the mechanical calculations on one disk and the electrical calculations on another disk) associated with the initial selected components, should be available at the Regional Office no later than January 18, 2007. 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 on January 29, 2007.
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. George Hausman. We understand that our regulatory assurance contact for this inspection is Mr. Richard Miester of your organization. In order to facilitate the inspection, we request that a contact individual be assigned to each inspector to ensure information requests, questions, and concerns are addressed in a timely manner. If there are any questions about the inspection or the material requested in the enclosure, please contact the lead inspector at (630) 829-9743 or via e-mail at gmh1@nrc.gov.
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/
