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

I. Information Requested Prior to the Information Gathering Visit

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.

1. Copy of the two most recently completed tests confirming thermal performance of each

HX. Include documentation and procedures that identify the types, accuracy, and

location of any special instrumentation used for these tests (e.g., high accuracy

ultrasonic flow instruments or temperature instruments). Include calibration records for

the instruments used during these tests;
