SUBJECT: KEWAUNEE POWER STATION - NOTIFICATION OF AN NRC TRIENNIAL
HEAT SINK PERFORMANCE INSPECTION AND REQUEST FOR
INFORMATION 05000305/2009005
Dear Mr. Heacock:
On November 16, 2009, the NRC will begin the on-site portion of the Triennial Heat Sink
Performance Inspection at your Kewaunee Power Station. 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 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 of documents requested is those items needed to support our in-office
preparation activities. This set of documents, including the calculations associated with the
B Emergency Diesel Generator (EDG) and Residual Heat Removal (RHR) heat exchangers
and the Ultimate Heat Sink, should be available at the Regional Office no later than
November 4, 2009. This information should be separated for each selected component,
especially if provided electronically (e.g., folder with component name that includes
calculations, condition reports, maintenance history, etc). During the in-office preparation
activities, the inspector may identify additional information needed to support the inspection.
- The last group includes the additional information above as well as plant specific
reference material. This information should be available on-site to the inspector on
November 16, 2009. It is also requested that corrective action documents and/or
questions developed during the inspection be provided to the inspector as the documents
are generated.
The lead inspector for this inspection is Michael A. Jones Jr. If there are questions about the
material requested, or the inspection, please call Mr. Jones at (630) 829-9745. Please send
the information to the following e-mail address Michael.Jones@nrc.gov. A hard-copy with the
required information is also an acceptable option.

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.
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), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html
(the Public Electronic Reading Room).

I. Information Requested By November 4, 2009
1. For the B Emergency Diesel Generator (EDG) and Residual Heat Removal (RHR) heat
exchangers:
a. Copies of the two most recent completed tests confirming thermal performance for
those heat exchangers which are performance tested.
b. Copy of system description and design basis document for the heat exchangers (as
applicable).
c. Copy of any operability determinations or other documentation of degradation
associated with the heat exchangers or the systems that support the operation for
the selected heat exchangers.
d. Copy of the Updated Final Safety Analysis Report (UFSAR) sections applicable for
each heat exchanger.
e. Provide a list of calculations with a description which currently apply to each heat
exchanger.
2. List of the Generic Letter (GL) 89-13, Service Water System Problems Affecting
Safety-Related Equipment, heat exchangers in order of risk significance.
3. System health report(s) and maintenance rule system notebooks for all the GL 89-13
heat exchangers
4. Copies of procedures developed to implement the recommendations of GL 89-13, e.g.,
the GL 89-13 Heat Exchanger Program description.

5. 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.
6. Updated Final Safety Analysis Report pages for the GL 89-13 Heat Exchanger Program.
7. Maximum Cooling Water system inlet temperature limit that still allows full licensed
power operation of the nuclear reactor. Please provide the document that states this
limit (e.g., USAR or TRM) and the operating procedure that ensures this limit is not
exceeded.
8. Copy of any self-assessment done on any of GL 89-13 heat exchangers.
II. Information Requested to be Available on First Day of Inspection, November 16, 2009
1. For the specific heat exchangers selected:
a. Copy of the design specification and heat exchanger data sheets for each heat
exchanger.
b. Copy of the vendor manuals including component drawings for each heat
exchanger.
c. 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.
d. 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).
e. Copy of the calculations or documents which evaluate the potential for water
hammer or excessive tube vibration in the heat exchanger or associated piping.
f. List of engineering-related Operator Workarounds/Temporary Modifications for these
heat exchangers since the last Heat Sink Performance
g. Documentation and procedures that identify the types, accuracy, and location of any
special instrumentation used for the two most recently completed thermal
performance tests for the heat exchangers (e.g., high accuracy ultrasonic flow
instruments or temperature instruments). Include calibration records for the
instruments used during these tests.
h. Copies of those documents that describe the methods taken to control water
chemistry in the heat exchangers.
i. Copies of the documents that verify the structural integrity of the heat exchanger,
e.g., eddy current summary sheets, ultrasonic testing results, and visual inspection
results.
