SUBJECT: BRAIDWOOD STATION NOTIFICATION OF AN NRC TRIENNIAL HEAT SINK

PERFORMANCE INSPECTION AND REQUEST FOR INFORMATION

05000456/2008005; 05000457/2008005

Dear Mr. Pardee:

On March 26, 2008, we informed you of a Triennial Heat Sink Inspection at your Braidwood

Station planned for June 23, 2008. After agreement with your staff, we rescheduled the

inspection to start on December 15, 2008. This inspection will be performed in accordance with

NRC baseline inspection procedure (IP) 71111.07. The systems that have been selected for

detailed review during this baseline inspection are the 1A SX Pump Lube Oil Cooler and the 2A

RHR Heat Exchanger.

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 first 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

December 5, 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 onsite to the inspector on

December 15, 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.

All requested documents are to cover the time period from the onsite 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.

C. Pardee -2-

The lead inspector for this inspection is Michael A. Jones Jr. If there are questions about the

material requested, or the inspection, please call Mr. Michael A. Jones Jr. at (630) 829-9745.

Please send the information to the following e-mail address michael.jones@nrc.gov. A

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

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).
