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 NRC's
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. UNITED STATES NUCLEAR REGULATORY COMMISSION REGION IV 1600 E LAMAR BLVD ARLINGTON, TX 76011-4511
O. Limpias - 2 -
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 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
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).
Sincerely,

Inspection Dates: February 23-27, 2015
Inspection Procedure: IP 71111.07, Triennial "Heat Sink Performance" Inspector: Robert Latta, Senior Reactor Inspector
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 16. Copies of the system training manuals for the selected heat exchangers 17. Provide a list of calculations with a description which currently apply to each heat exchanger
18. Copies of vendor data sheets and design basis data for the selected heat exchangers
- 3 - 19. 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 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
