PALISADES NUCLEAR PLANT NOTIFICATION OF AN NRC BIENNIAL HEAT SINK PERFORMANCE INSPECTION AND INFORMATION REQUEST

Dear Mr. Schwarz:

On November 26, 2007, the NRC will begin the onsite portion of the Biennial Heat Sink Performance Inspection at your Palisades Nuclear Plant. This inspection will be performed in accordance with NRC baseline Inspection Procedure (IP) 71111.07.

In order to minimize the impact that the inspection has onsite 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 to ensure the inspector is adequately prepared for the inspection. This information should be sent to the Region III office, no later than November 15, 2007, to ensure that we may review these documents before the onsite inspection.

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 to minimize the number of documents requested during the preparation week or during the onsite inspection. The information requested should envelop the time period from the onsite inspection period back to the last Heat Sink Performance Inspection.

The lead inspector for this inspection is Mr. M. Holmberg. If there are questions about the material requested, or the inspection, please call Mr. Holmberg at (630) 829-9748.

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 System (PARS) component of NRC's Agencywide Documents Access and Management 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:

November 26 - 30, 2007 Inspection Procedure:

IP 71111.07, Biennial Heat Sink Performance Inspection Lead Inspector:

Melvin Holmberg (630) 829-9748, msh@nrc.gov I.

Information Requested for In-Office Review and Preparation The following information (prefer electronic format e.g., CD rom disc) is to be provided to M. Holmberg at the Region III Office (2443 Warrenville Rd., Ste. 201, Lisle, IL 60532) no later than November 15, 2007, to support the biennial Heat Sink Performance Inspection, IP 71111.07. If some of the activities are not available because they have not been performed by your program, please note that fact. The information requested should envelop the time period from the onsite inspection period back to the last Heat Sink Performance Inspection. If nothing addressing the request was done in that time period, then the request applies to the last applicable document in the previous time period. Unless otherwise specified, all the below requests are for the selected heat exchangers (Hxs):

component cooling water heat exchanger E-54B; and emergency diesel generator 1-1 jacket water heat exchanger.

1.

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

2.

A list of corrective action program documents (with a short description) associated with Hxs, 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.
