SUBJECT:
PALO VERDE NUCLEAR GENARATING STATION - NOTIFICATION OF NRC
TRIENNIAL HEAT SINK PERFORMANCE INSPECTION
(05000528/529/530/2012003)
Dear Mr. Edington:
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 the Palo Verde Nuclear
Generating Station Units 1, 2, and 3. The inspection will be comprised of two reactor inspectors
(one in training) 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 - May 7-11, 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 April 30, 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 Del Elkinton of your licensing organization. If
there are any questions about this inspection or the material requested, please contact the
inspector, Gerond A. George, at 817-200-1562 or by email, Gerond.George@nrc.gov.

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 or digital media preferred), in care of Gerond A. George, by
April 30, 2012. The inspectors 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.
