SUBJECT:

FERMI POWER PLANT - NOTIFICATION OF AN NRC BIENNIAL HEAT SINK PERFORMANCE INSPECTION AND INFORMATION REQUEST

Dear Mr. Cobb:

On March 19, 2007, the NRC will begin the Biennial Heat Sink Performance Inspection at your Fermi Power Plant. This inspection will be performed in accordance with NRC baseline inspection procedure 71111.07. The systems selected for detailed review during this baseline inspection are the Emergency Equipment Cooling Water (EECW) Heat Exchanger (Division 1),

the HPCI Room Cooler, and the RCIC Room Cooler.

We have enclosed requests for the documents needed for this inspection.

This information can be sent to the following e-mail address dls3@nrc.gov or mailed on a disk.

Please send the information by February 26, 2007, so 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 Mr. Darrell Schrum. If there are questions about the material requested, or the inspection, please call (630) 829-9741.

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

BIENNIAL HEAT SINK INSPECTION DOCUMENT REQUEST Inspection Dates: March 19 through 23, 2007 Inspection Procedure: IP 71111.07 Heat Sink Performance Lead Inspector: D. Schrum (630) 829-9741, dls3@nrc.gov Information Requested Prior to the Information Gathering Visit The systems selected for detailed review during this baseline inspection are the Emergency Equipment Cooling Water (EECW) Heat Exchangers (Division 1), the HPCI Room Cooler, and the RCIC Room Cooler. Unless otherwise specified, all the below requests are for the selected heat exchangers (HXs).

1) Copies of the two most recent completed tests confirming thermal performance for those heat exchangers which are performance tested. In addition, for the most recently completed test confirming thermal performance of the sample heat exchangers, please provide 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

2) A list of corrective action program documents (with a short description) associated with heat exchangers, heat sinks, silting, corrosion, fouling, or heat exchanger testing, that are documented in your corrective action system (for the previous 2 years or since the last biennial heat sink inspection), This request is for all the Generic Letter 89-13 HXs and the ultimate heat sink

3) Copy of system description and design basis document for the heat exchangers under review (as applicable)

4) Copy of any operability determinations or other documentation of degradation associated with the heat exchangers or the systems that support the operation of the heat exchangers

5) Copy of any self-assessment done within last 2 years on any of the licensees heat exchanger programs (e.g., Generic Letter 89-13 program heat exchangers) or on the sample heat exchangers

6) A schedule of all inspections, cleanings, maintenance, or testing of any plant heat exchanger to be done during the on-site portion of the inspection 1 Enclosure

BIENNIAL HEAT SINK INSPECTION DOCUMENT REQUEST

7) Listing of the GL 89-13 heat exchangers by risk significance

8) List of operability evaluations currently relied upon and those that were previously (past 2 years) relied upon for operability

9) Copy of the evaluations of data for the two most recent completed tests confirming the thermal performance of each heat exchanger

10) Provide copy of the calculation which establishes the limiting (maximum) design basis heat load which is required to be removed by each of these heat exchangers

11) Copy of the calculation which correlates surveillance testing results from these heat exchangers with design basis heat removal capability (e.g., basis for surveillance test acceptance criteria)

12) The clean and inspection maintenance schedule for each heat exchanger for the next five years

13) Copy of the document describing the inspection results for the last two clean and inspection activities completed on each heat exchanger

14) Copy of the document which identifies the current number of tubes in service for each heat exchanger and the supporting calculation which establishes the maximum number of tubes which can be plugged in each heat exchanger
