SUBJECT:
PALO VERDE NUCLEAR GENERATING STATION - NOTIFICATION OF NRC
TRIENNIAL HEAT SINK PERFORMANCE INSPECTION (05000528/2018004,
05000529/2018004, AND 05000530/2018004) AND REQUEST FOR
INFORMATION
Dear Mr. Bement:
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 Palo Verde Nuclear Generating
Station from November 5 - 9, 2018. The inspection will consist of two reactor inspectors from
the NRCs Region IV office for one week. The inspection will be conducted in accordance with
NRC Inspection Procedure 71111, Attachment 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 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, 2018. Also,
appropriate personnel knowledgeable of heat exchangers should be available to support the
inspectors 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 Lorraine Weaver of your licensing organization.
If there are any questions about this inspection or the material requested, please contact the
lead inspector, Chris Smith, by telephone at 817-200-1095 or by e-mail at Chris.Smith@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 Agency Rules of Practice and Procedure, 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).

Information Requested for the In-Office Preparation Week
The following information should be made available to the lead inspector, Chris Smith, by
October 29, 2018. Please note that additional information may be requested during the onsite
portion of the inspection. It is preferable to have the information provided in electronic format,
although the information may also be sent to the Region IV office in hard copy to the attention
the lead inspector. Also, we request that you categorize the documents in your response with
the numbered list below. If any requested documents are large and only hard copy formats are
available, please inform the inspector, and provide the documentation during the first day of the
onsite inspection. Additionally, requested documents such as corrective action program
documents are to be for the time period from the current onsite inspection back to the previous
triennial heat sink performance inspection. Requested documents such as surveillances,
maintenance tasks, or thermal performance tests are to be the last three performances of those
activities. If the requested documentation does not apply to the sample selection for this
inspection, no response is necessary. If the information requested above will not be available or
if there are questions regarding this information request, please contact the lead inspector as
soon as possible.
