SUBJECT:
KEWAUNEE NUCLEAR POWER PLANT ANNOUNCEMENT OF SPECIAL INSPECTION
Dear Mr. Coutu:
As part of a Davis-Besse Lessons-Learned Task Force Recommendation [3.1.2(5)]
commitment, NRC is in the process of issuing a temporary instruction (TI) to review licensees continued actions in response to Generic Letter 89-13, "Service Water System Problems Affecting Safety-Related Equipment." The primary objective of the TI is to review licensees activities in response to NRC generic communications. Additionally, this TI will gather information to help the NRC staff identify and shape possible future regulatory positions and enhance the agency operating experience program.
Kewaunee was selected as one of the three sites in Region III at which this TI will be conducted. This inspection will occur during the week of August 16, 2004. This inspection will replace the biennial heat sink inspection that was previously scheduled for December 2004. In addition, other baseline inspection samples will be credited as completed based on completion of this TI.
In order to best accomplish the requirements of the TI within the short time frame allotted, to minimize the impact that the inspection has on the site and to ensure a productive inspection for both sides, 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 inspection team is adequately prepared for the inspection. This information should be available to the Regional Office, with a copy to the resident office, by no later than August 9, 2004. In so far as possible, this information should be provided electronically.
The second group of documents requested are those items which the team will review onsite.
During the preparation week, the lead inspector will coordinate with the technical or regulatory contact in regard to this group of documents. 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 onsite inspection.
The lead inspector for this inspection is Ms. Patricia Lougheed. If there are any questions about the material requested, or the inspection, please call the lead inspector at 630-829-9760 or e-mail her at vpl@nrc.gov.
T. Coutu In accordance with 10 CFR 2.390 of the NRCs "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 NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

A list of operating experience documents applicable to the above system and evaluated during the last two operating cycles; 6.
A list of service water system modifications, either permanent or temporary, going far enough back that three modifications can be reviewed; 7.
Information on the heat exchangers tested (inspected and cleaned) under Generic Letter 89-13, and the dates testing (Inspection and cleaning) was last performed; 8.
A list of corrective action documents pertaining to the above system, heat exchangers, heat sinks, or operating experience; and 9.
The name and phone numbers of the technical contact.
II.
Information Requested to be Available on First Day of Inspection We request that the following information be available to the team once it arrives onsite.
In some cases, it may be acceptable to have the information available electronically, provided the inspectors have access to it.
