SUBJECT:

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

Dear Mr Pearce:

On February 26, 2007, the NRC will begin the on-site portion of the Biennial Heat Sink Performance Inspection at your Perry Nuclear Power Plant. 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 train B Emergency Closed Cooling system heat exchanger and the High Pressure Core Spray room cooler.

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 documents have been divided into two groups. The first group lists information necessary in order to ensure the inspector is adequately prepared for the inspection. This information can be sent to the following e-mail address gfo@nrc.gov, no later than February 14, 2007, so that we may start the review of these documents. A hard-copy with the required information is also an acceptable option.

The second group of documents requested are those items which the inspector will review or need access to during the onsite inspection. 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 on-site inspection.

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.

W. Pearce 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 (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: February 26 - March 2, 2007 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 February 14, 2007, to support the biennial Heat Sink Performance Inspection, IP 71111.07. If some of the activities are not performed by your program, please note that fact. Unless otherwise specified, all the below requests are for the selected heat exchangers (Hxs):

• train B Emergency Closed Cooling system heat exchanger; and

• the High Pressure Core Spray room cooler.

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

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 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 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 1 Enclosure

BIENNIAL HEAT SINK PERFORMANCE INSPECTION DOCUMENT REQUEST Initial Document Request

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

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

We request that the following information be available to the inspector once he arrives on-site February 26, 2007:

1. For the two most recently completed tests 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

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 manuals including component drawings for each heat exchanger 2 Enclosure
