SUBJECT:

DAVIS-BESSE NUCLEAR POWER STATION - REQUEST FOR INFORMATION FOR AN NRC TRIENNIAL BASELINE COMPONENT DESIGN BASES INSPECTION (CDBI) INSPECTION REPORT 05000346/2009007(DRS)

Dear Mr. Allen:

On October 19, 2009, the NRC will begin a triennial baseline Component Design Bases Inspection (CDBI) at the Davis-Besse Nuclear Power Station. 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 components that 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 the 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 three weeks on-site. 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: October 19-23, 2009; November 2-6, 2009; and November 16-20, 2009.

The team will be preparing for the inspection, mainly during the week of October 13, 2009, as discussed in the attached enclosure. A Region III Senior Reactor Analyst may accompany the inspection team during the week of October 19, 2009, 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 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.

B. Allen 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 September 8, 2009.

By September 25, 2009, the lead inspector will communicate the initial selected set of approximately 30 high risk 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 9, 2009. 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 October 19, 2009. 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. R. Langstaff. We understand that our licensing contact for this inspection is Mr. T. Chowdhary 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) 829-9747 or via e-mail at ronald.langstaff@nrc.gov.

In accordance with 10 CFR 2.390 of the NRCs 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 NRCs 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/
