SUBJECT:

DAVIS-BESSE NUCLEAR POWER STATION - NOTIFICATION OF AN NRC BIENNIAL HEAT SINK PERFORMANCE INSPECTION AND INFORMATION REQUEST

Dear Mr. Bezilla:

On December 11, 2006, the NRC will begin the on-site portion of the Biennial Heat Sink Performance Inspection at your Davis-Besse Nuclear Station. This inspection will be performed in accordance with NRC baseline inspection procedure (IP) 71111.07. The heat exchangers selected for detailed review during this baseline inspection are the Control Room Emergency Ventilation (CREV) system train 1 condenser and the Auxiliary Feedwater system train 2 oil cooler.

We have enclosed a request for documents needed for the inspection. This information can be sent to the following e-mail address gfo@nrc.gov, no later than November 27, 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 Mr. Gerard ODwyer. If there are questions about the material requested, or the inspection, please call Mr. Gerard 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

M. Bezilla 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).

Sincerely,

/RA/

Inspection Dates: December 11-15, 2006 Inspection Procedures: IP 71111.07, Biennial Heat Sink Performance Inspection Lead Inspector: G. ODwyer (630) 829-9624, gfo@nrc.gov I. Information Requested Expeditiously The following information is requested to be provided as soon as possible, but no later than November 27, 2006, to support the biennial Heat Sink Performance Inspection, IP 71111.07. Unless otherwise specified, all the below requests are for the selected heat exchangers:

• Control Room Emergency Ventilation (CREV) system train 1 condenser

• Auxiliary Feedwater system train 2 oil cooler.

1. Copies of the procedures used to monitor, inspect, clean or test heat exchanger performance;

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 two years or since the last biennial heat sink inspection), this item is for all the Generic Letter 89-13 Hxs and the ultimate heat sink; 3 Copy of system description and/or 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 two years on any of the licensees heat exchanger programs (e.g., Generic Letter 89-13 program heat exchangers) or on the sample heat exchangers; and 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.

Initial Document Request II. Information Requested to be Available on First Day of Inspection The following requests are only for the two HXs selected as samples unless otherwise stated. We request that the following information be available to the inspector once he arrives on-site December 11, 2006:

1. Copies of the two most recently completed tests confirming thermal performance for those heat exchangers which are performance tested. 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;

2. Copy of the evaluations of data for the two most recent completed tests confirming the thermal performance of each heat exchanger;

3. 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;

4. 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);

5. The clean and inspection maintenance schedule for each heat exchanger for the next five years;

6. Copy of the document describing the inspection results for the last two clean and inspection activities completed on each heat exchanger;

7. 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;

8. Copy of the document establishing the repair criteria (plugging limit) for degraded tubes which are identified in each heat exchanger;

9. Copy of the design specification and heat exchanger data sheets for each heat exchanger;

10. Copy of the vendor/component drawings for each heat exchanger;

11. Copy of the calculations or documents which evaluate the potential for water hammer or excessive tube vibration in the heat exchanger or associated piping;

12. Copy of heat exchanger performance trending data tracked for each heat exchanger; 2 Enclosure

Initial Document Request

13. Copies of those documents that describe the methods taken to control water chemistry in the heat exchangers;

14. Copies of the documents that verify the following for the ultimate heat sink:

• sufficient reservoir capacity 15 Copies of the documents that verify the following for the ultimate heat sink:

• for underwater UHS weirs or excavations, that visual or other inspections have been performed to check for:
