SUBJECT: ARKANSAS NUCLEAR ONE - NOTIFICATION OF NRC TRIENNIAL HEAT
EXCHANGER INSPECTION (05000313/2012005 & 05000368/2012005)
Dear Mr. Schwartz:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission Region IV
staff will conduct a triennial heat sink performance inspection at your Arkansas Nuclear One
facility. The inspection will be comprised of one reactor inspector from the NRC Region IV
office. The inspection will be conducted in accordance with Inspection Procedure 71111.07,
"Heat Sink Performance."
The schedule for the inspection is as follows:
Onsite inspection - November 5 - 9, 2012
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 onsite 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 October 29, 2012. We
request, that during the onsite 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 that 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 Natalie Mosher of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspector, Robert Latta, at 817-200-1532 or by email, 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 document system
(ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-

Heat Sink Performance Inspection Document Request
Inspection Dates: November 5 - 9, 2012
Inspection Procedures: IP 71111.07, Triennial Heat Sink Performance
Inspector: Robert Latta, Sr. 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 (ims.certrec.com database preferred), in care of Robert Latta, by October 29, 2012. The
inspector will select specific items from the information requested below and then request from
your staff additional documents needed during the onsite inspection week. Also, we request
that you categorize the documents in your response with the numbered list below. Please
provide requested documentation electronically if possible. 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 onsite 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:
- Unit 1 Decay Heat Room Cooler VUC-1A
- Unit 1 Decay Heat Room Cooler VUC-1B
- Unit 2 Containment Cooler 2VCC-2B
- Unit 2 High Pressure Injection Pump Room Cooler 2VUC-11B
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 GL 89-13
heat exchangers.
3. Copy of any self-assessments done on any GL 89-13 heat exchangers in the previous
