March 26, 2007 Mr. David A. Christian Senior Vice President and Chief Nuclear Officer Innsbrook Technical Center 5000 Dominion Boulevard Glen Allen, VA 23060-6711
SUBJECT:
KEWAUNEE POWER STATION - NOTIFICATION OF AN NRC BIENNIAL HEAT SINK PERFORMANCE INSPECTION AND INFORMATION REQUEST
Dear Mr. Christian:
On April 16, 2007, the NRC will begin the on-site portion of the Biennial Heat Sink Performance Inspection at your Kewaunee Power 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 inspections are the 1A Component Cooling Heat Exchanger (component ID 135-081) and the Residual Heat Removal (RHR) pump pit fan coil unit 1A (component ID 155-051).
In order to minimize the impact that the inspections have on the site and to ensure productive inspections, 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 inspections. This information must be sent to the following e-mail address gfo@nrc.gov, no later than April 4, 2007, to ensure that we may review these documents before the on-site inspection. 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 on-site inspection. It is important that both groups of 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. Both groups of requests are only for the time period from the on-site 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.
The lead inspector for this inspection is Gerard ODwyer. If there are questions about the material requested, or the inspection, please call him at (630) 829-9624.
D. Christian 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).

BIENNIAL HEAT SINK PERFORMANCE INSPECTION DOCUMENT REQUEST Initial Document Request Enclosure 1
Inspection Report: 0500440/2007003(DRP)
Inspection Dates:
April 16 - 20, 2007 onsite Inspection Procedure:
IP 71111.07, Biennial Heat Sink Performance Inspection Lead Inspector:
Gerard 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 April 4, 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. Both groups of requests are only for the time period from this onsite inspection period back to the last biennial 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 time period before the previous biennial Heat Sink Performance Inspection. Unless otherwise specified, all the below requests are for the two heat exchangers (Hxs) selected as samples:
a.
The 1A Component Cooling Heat Exchanger (component ID 135-081); and b.
the Residual Heat Removal (RHR) pump pit fan coil unit 1A (component ID 155-051).
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 any of the Generic Letter (GL) 89-13 heat exchangers and the UHS concerning silting, corrosion, fouling, or testing since the last biennial heat sink inspection.
3.
Copy of system description and design basis document for the sample heat exchangers.
4.
Copy of any operability determinations or other documentation of degradation associated with the two selected heat exchangers or the systems that support the safety function of the heat exchangers.
5.
Copy of any self-assessment done on any of the licensees heat exchanger programs (e.g., GL 89-13 heat exchanger program) or on the sample heat exchangers.
