SUBJECT:
QUAD CITIES NUCLEAR POWER STATION, UNITS 1 AND 2 - NOTIFICATION
OF AN NRC BIENNIAL HEAT SINK PERFORMANCE INSPECTION AND
INFORMATION REQUEST 05000254/2006007; 05000265/2006007(DRS)
Dear Mr. Crane:
On December 18, 2006, the NRC will begin the Biennial Heat Sink Performance Inspection at
your Quad Cities Nuclear Power Station. This inspection will be performed in accordance with
NRC baseline inspection procedure 71111.07B. The heat exchangers selected for detailed
review during this baseline inspection are the 1B and 2B core spray pump room cooler, and the
1A and 2B emergency diesel generator engine cooler.
We have enclosed a request for documents needed for the inspection. This information can be
sent to the following e-mail address cea4@nrc.gov, no later than December 8, 2006, so that we
may start the review of these documents. A hard-copy with the required information is also an
acceptable option.
The lead inspector for this inspection is Ms. Caroline Acosta Acevedo. If there are questions
about the material requested, or the inspection, please call Ms. Acosta Acevedo at
(630) 829-9718.
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
