SUBJECT:

DAVIS-BESSE NUCLEAR POWER STATION - NOTIFICATION OF AN

NRC TRIENNIAL HEAT SINK PERFORMANCE INSPECTION AND

REQUEST FOR INFORMATION 05000346/2008004

Dear Mr. Allen:

On August 25, 2008, the NRC will begin the on-site portion of the Triennial Heat Sink

Performance Inspection at your Davis-Besse Nuclear Power Station. This inspection will

be performed in accordance with NRC baseline inspection procedure (IP) 71111.07.

In order to minimize the impact that the inspection has on the site and to ensure a

productive inspection, we have enclosed a request for documents needed for the

inspection. The documents have 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 July 14, 2008.

By July 25, 2008, the inspector will communicate the initial selected set of approximately

2-3 risk significant heat exchangers.

  • 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 selected heat exchangers, should be available at the Regional Office no later

than August 18, 2008. This information should be separated for each selected

component, especially if provided electronically (e.g., folder with component name that

includes calculations, condition reports, maintenance history, etc.). During the in-office

preparation activities, the inspector 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 on-site to the inspector on

August 25, 2008. It is also requested that corrective action documents and/or questions

developed during the inspection be provided to the inspector as the documents are

generated.

Please send the information to the following e-mail address gerard.odwyer@nrc.gov. A

hard-copy with the required information is also an acceptable option.

B. Allen

It is important that these documents be as complete as possible, in order to minimize the

number of documents requested during the preparation week or during the on-site

inspection.

All requested documents are to be for the time period from the on-site inspection period

back to the last Heat Sink Performance Inspection. If nothing addressing a request was

done in that time period, then the request applies to the last applicable document in the

previous time period.

The lead inspector for this inspection is Mr. Gerard ODwyer. If there are questions about

the material requested, or the inspection, please call Mr. ODwyer at (630) 829-9624.

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).
