SUBJECT:
COOPER NUCLEAR STATION - NOTIFICATION OF NRC TRIENNIAL HEAT
SINK PERFORMANCE INSPECTION 05000298/2015001 AND REQUEST FOR
INFORMATION
Dear Mr. Limpias:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff
will conduct a triennial heat sink performance inspection at your Cooper Nuclear Station from
February 23-27, 2015. The inspection will consist of one reactor inspector from the NRCs
Region IV office for one week. The inspection will be conducted in accordance with NRC
Inspection Procedure 71111.07, "Heat Sink Performance."
Experience has shown that this inspection is resource intensive, both for the NRC inspectors
and your staff. In order to minimize the impact to your on-site resources and to ensure a
productive inspection, we have enclosed a request for documents needed for this inspection.
Please note that the documents are requested to be provided by February 9, 2015. We request
that during the on-site inspection week, you ensure that copies of analyses, evaluations, or
documentation regarding the implementation and maintenance of your heat exchanger program
are available. Of specific interest are those documents that establish your heat exchanger
program satisfies NRC regulatory requirements and conforms to applicable NRC guidance.
Also, appropriate personnel knowledgeable of safety-related heat exchangers should be
available to support the inspector at the site during the inspection.
We have discussed the schedule for this inspection activity with your staff and understand that
our regulatory contact for this inspection will be Brenda Kirkpatrick of your licensing
organization. If there are any questions about this inspection or the material requested, please
contact the inspector, Robert Latta, by telephone at 817-200-1532 or by e-mail at
Robert.Latta@nrc.gov.

This letter does not contain new or amended information collection requirements subject
to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information
collection requirements were approved by the Office of Management and Budget, control
number 3150-0011. The NRC may not conduct or sponsor, and a person is not required
to respond to, a request for information or an information collection requirement unless the
requesting document displays a currently valid Office of Management and Budget control
number.
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 NRC's
Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible
from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic
Reading Room).

Information Requested for the In-Office Preparation Week
The following information should be sent to the Region IV office in hard copy or electronic
format (Certrec IMS preferred) to the attention of Robert Latta, by February 9, 2015. The
inspector will select specific items from the information requested below and then request from
your staff additional documents needed during the on-site inspection week. We also request
that you categorize the documents in your response with the numbered list below. Please
provide requested documentation electronically if possible. Additionally, for Adobe portable
document files (.pdf) please make the text searchable. If requested documents are large and
only hard copy formats are available, please inform the inspector and provide subject
documentation during the first day of the on-site inspection. If you have any questions
regarding this information request, please call the lead inspector as soon as possible.
The following heat exchangers/heat sinks have been selected for inspection:
Division 1 Residual Heat Removal Heat Exchanger
Division 1 and 2 Reactor Equipment Cooling Heat Exchangers
Diesel Generator 1, Jacket Water and Lube Oil Heat Exchangers
For all Generic Letter 89-13 exchangers:
1. List of corrective action program documents (with a short description) associated with
Generic Letter 89-13 heat exchangers, heat sinks, silting, corrosion, fouling, heat
exchanger cavitation, or heat exchanger testing in the previous three years
2. System health report(s) and maintenance rule system notebooks for all the Generic
Letter 89-13 heat exchangers
3. Copy of any self-assessments done on any Generic Letter 89-13 heat exchangers in the
previous three years
4. Copies of any procedures developed to implement the recommendations of Generic
Letter 89-13 (e.g., the Generic Letter 89-13 Heat Exchanger Program description)
5. Copies of any commitments to the Generic Letter 89-13 program
- 2 -
For the specific heat exchangers selected:
Testing Documents
6. Copies of the two most recently completed tests confirming thermal performance for
those heat exchangers which are performance-tested
7. Instrument uncertainties of the instruments used during testing
8. 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
9. Documents that show the as-found results are recorded, evaluated, and appropriately
dispositioned such that the as-left condition is acceptable
Cleaning Documents
10. The cleaning and inspection maintenance schedule for each heat exchanger for the
next five years
11. Copy of the document describing the inspection results for the last two cleaning and
inspection activities completed on each heat exchanger
12. Cleaning procedures with acceptance criteria for the selected heat exchangers
13. 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)
14. Copies of those documents that describe the methods taken to control water chemistry
in the heat exchangers
Design Documents
15. Copies of the design basis documents and updated final safety analysis report pages
for the selected heat exchangers

which is required to be removed by each of these heat exchangers
20. 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)
21. Copy of the calculations or documents which evaluate the potential for water hammer or
excessive tube vibration in the heat exchanger or associated piping
22. 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
