SUBJECT: PALO VERDE NUCLEAR GENERATING STATION, UNITS 1, 2, AND 3 -
NOTIFICATION OF NRC TRIENNIAL HEAT SINK PERFORMANCE
INSPECTION (05000528/2020002, 05000529/2020002, AND
05000530/2020002) AND REQUEST FOR INFORMATION
Dear Mrs. Lacal:
On June 15, 2020, the Nuclear Regulatory Commission (NRC) will begin the onsite portion of
the Triennial Heat Sink Performance Inspection at your Palo Verde Nuclear Generating Station
Units 1, 2, and 3. This inspection will be performed in accordance with NRC baseline inspection
procedure (IP) 71111.07 by two inspectors from the NRCs Region IV office for one week.
In order to minimize the impact that the inspection has on the site and to ensure a productive
inspection, we have enclosed a request for documents needed for the inspection. The
documents have been divided into three groups.
- The first group lists information necessary for our initial inspection scoping activities.
This information should be available to the lead inspector no later than May 4, 2020.
By May 7, 2020, the inspector will communicate the initial selected set of approximately
two to three risk-significant heat exchangers.
- The second group of documents requested includes those items needed to support our
in-office preparation activities. This set of documents, including the calculations
associated with the selected heat exchangers, should be available no later May 26,
2020. This information should be separated for each selected component, especially if
provided electronically (e.g., folder with component name that includes calculations,
condition reports, maintenance history, etc.). During the in-office preparation activities,
the inspectors may identify additional information needed to support the inspection.
- The last group includes the additional information above as well as plant specific
reference material. This information should be available onsite to the inspectors on
June 15, 2020. It is also requested that corrective action documents and/or questions
developed during the inspection be provided to the inspector as the documents are
generated.
M. Lacal 2
It is important that these documents be as complete as possible in order to minimize the number
of documents requested during the preparation week or during the onsite inspection.
All requested documents are to be for the time period from the onsite inspection period back to
the last Triennial Heat Sink Performance Inspection. If nothing addressing a request was done
in that time period, then the request applies to the last applicable document in the previous time
period.
We have discussed the schedule for this inspection activity with your staff and understand that
our regulatory contact for this inspection will be Mr. D. Mohamed of your licensing organization.
If there are any questions about this inspection or the material requested, please contact the

Inspectors: Wayne C. Sifre, Senior Reactor Inspector
Fabian D. Thomas, Reactor Inspector
I. Information Requested by May 4, 2020:
1. List of the Generic Letter (GL) 89-13, Service Water System Problems Affecting Safety-
Related Equipment, heat exchangers in order of risk significance.
2. Copy of heat exchanger performance trending data tracked for each GL 89-13 heat
exchanger.
3. List of corrective action program documents (with a short description) associated with
GL 89-13 heat exchangers, heat sinks, silting, corrosion, fouling, or heat exchanger
testing, for the previous two years or since the last heat sink performance inspection.
4. Copy of any self-assessment done on any of GL 89-13 heat exchangers done since last
heat sink performance inspection.
5. System health report(s) and maintenance rule system notebooks for all the GL 89-13
heat exchangers.
6. Copy of your responses for GL 89-13.
II. Information Requested by May 26, 2020:
1. For the specific heat exchangers selected:
a. Copies of the two most recent completed tests confirming thermal performance for
those heat exchangers which are performance tested;
b. Copy of system description and design basis document for the heat exchangers (as
applicable);
c. 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;
d. Copy of the Updated Final Safety Analysis Report (UFSAR) sections applicable for
each heat exchanger; and
Enclosure
e. Provide a list of calculations with a description which currently apply to each heat
exchanger.
2. A schedule of all inspections, cleanings, maintenance, or testing of any plant heat
exchanger to be done during the onsite portion of the inspection.
3. Copies of procedures developed to implement the recommendations of GL 89-13,
(e.g., the GL 89-13 Heat Exchanger Program description).
4. Pages from the UFSAR for the GL 89-13 Heat Exchanger Program.
5. Maximum GL 89-13 heat exchanger inlet temperatures that still allow full licensed power
operation of the nuclear reactor. Please provide the documents that state these limits
(e.g., UFSAR or Technical Requirements Manual (TRM)) and the operating procedures
that ensure these limits are not exceeded.
III. Information Requested by June 15, 2020
1. For the specific heat exchangers selected:
a. Provide the Design Basis Documents and Updated Final Safety Analysis Report
pages for the selected heat exchangers;
b. Copy of the design specification and heat exchanger data sheets for each heat
exchanger;
c. Copy of the vendor manuals including component drawings for each heat exchanger;
d. 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;
e. 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);
f. Copy of the calculations or documents which evaluate the potential for water
hammer or excessive tube vibration in the heat exchanger or associated piping;
g. List of engineering-related Operator Workarounds/Temporary Modifications for these
heat exchangers since the last Heat Sink Performance Inspection;
h. Copy of the evaluations of data for the two most recent completed tests confirming
the thermal performance of each heat exchanger;

special instrumentation used for the two most recently completed thermal
performance tests for the heat exchangers (e.g., high accuracy ultrasonic flow
instruments or temperature instruments). Include calibration records for the
instruments used during these tests;
2
j. Copies of those documents that describe the methods taken to control water
chemistry in the heat exchangers;
k. 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;
l. The cleaning and inspection maintenance schedule for each heat exchanger for the
next 5 years;
m. Copy of the document describing the inspection results for the last two cleaning and
inspection activities completed on each heat exchanger;
n. 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 of tubes which can be plugged in each heat exchanger;
o. Copy of the document establishing the repair criteria (plugging limit) for degraded
tubes which are identified in each heat exchanger; and
p. Information regarding any alarms which monitor on-line performance.
2. For the ultimate heat sink (UHS):
a. Maintenance or inspection of inaccessible below-water portions of the UHS system
including results of underwater diving inspections and assessments of sediment
intrusion and/or removal of sediment; and
b. Documentation of inspections to verify no structural damage to intake structures that
would indicate loss of structural integrity and/or capacity.
