Attention:
Mr.
M.
F.
Conway
Executive Vice President,
Nuclear
Gentlemen:
Subject:
NRC Inspection of Palo Verde Units 1,
2 and
3
This refers to the inspection
conducted
by Messrs.
D.
Coe, J.
Ringwald,
J.
Sloan,
M. Ang,
and
A. D'Angelo, from April 15 through
May 26,
1990, of
activities authorized
by
NRC License
Nos.
and
the discussion of .our findings held by the inspectors
with members of the
Arizona Public Service
Company staff at the conclusion of the inspection.
Areas
examined during this inspection
are described
in the enclosed
inspection
report.
Within these
areas,
the inspection consisted
of selective
examinations
of procedures
and representativ'e
records,
interviews with
personnel,
and observations
by the inspectors.
This report refers to several
instances
in which improper valve manipulations
contributed to actual
or potential
component operability problems or to the
unexpected transfer of Reactor Coolant System
(RCS) water.
The most
significant of these
include the isolation of an Atmospheric
Dump Valve
accumulator while in Mode 1, the starting of a charging
pump with the suction
and discharge
valves closed,
overpressurizing
part of the Post-Accident
Sampling System,
an
and the inadvertent transfer of water
in the Refueling Mater Tank to the
RCS in Unit 1.
These incidents reflect a
need for more rigorous control over system manipulations.
In addition, the
loss of shutdown cooling event described
in the enclosed
inspection report and
the
RCS leak while performing repacking of a valve with the train in service
described
in Inspection
Report 50-528/90-12 point to the necessity of careful
considerations
of actions while shutdown cooling systems
are in service.
Based
on the results of this inspection, it appears
that two of your
activities were not conducted in full compliance with NRC requirements,
as set
forth in the Notice of Violation, enclosed
herewith
as Appendix A.
Two occasions
were noted in this report in which on-site
System
Engineers
identified problems with their assigned
systems.
These
instances
involved the
identification of the oil collection piping for a Reactor
Coolant
Pump not
being in the proper configuration
and the identification of paint on fuel
metering rod ports of an Emergency
Diesel Generator.

This appears
to be evidence of ownership
and
a pro-active role on the part of
your engineering staff.
We find these
observations
by your system engineers
to be significant contributions to ensuring
equipment operability,
and
encourage
continuation of this level of performance.
Your response
to this Notice is to be submitted in accordance
with the
provisions of 10 CFR Part 2.201
as stated
in Appendix A, Notice of Violation.
In accordance
with 10 CFR Part 2.790(a),
a copy of this letter and the
enclosures will be placed in the
NPC Public Document
Room.
The response
directed
by this letter and the accompanying
Notice are not
subject to the clearance
procedure of the Office of Management
and Budget
as required
by the Paperwork Reduction Act of 1980,
PL 96-511.
Should you have
any questions
concerning this inspection,
we will be pleased
to discuss
them with you.
Sincerely,
