Attention:
Mr.
W.
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,
T. Polich,
J.
Ringwald,
P.
squalls,
and
C.
Myers of this 'office from August
7 through
September
10,
1989, of activities authorized
by
NRC License
Nos.
and to the discussion
of our findings held by the
inspectors with members of the Arizona Nuclear
Power Project 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 representative
records,
interviews with personnel,
and observations
by the inspectors.
Based
on the results of this inspection, it appears
that several
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.
The enclosed
report and notice of violations discuss
several
concerns
which appear to warrant your attention.
These
concerns
are
summarized
as
fol 1 ows:
Paragraph
2.b describes
an issue involving the alignment of
Emergency Diesel Generator air start
system valves.
Our review has
concluded that the actual
system alignment
was not consistent with
the associated
calculational
assumptions,
and furthermore,
once this
was brought to the attention of your engineering organization,
the
interim action identified by engineering
was not performed at
Unit 3,
as subsequently
identified by
NRC personnel.
Paragraphs
2.f, 7,
and 21 discuss
three separate
instances
where
your reviews of NRC Information Notices were considered
weak.
In
two of the instances,
more comprehensive
reviews could have
potentially prevented plant events
which followed your reviews.
As
we have previously discussed
with you,
an important element of
nuclear
power plant operations
is learning from both your own
experience
and the experience
of others.
Therefore this issue is of
particular concern.

Paragraph
7 discusses
the-misalignment of 'valves associated
with the
Spent
Fuel
Pool at Unit 1.
This event is of concern
due to your
past problems with ensuring proper
valve alignments.

you to consider these
issues
and their underlying causes
while conducting your reviews in preparation for the startup of U t
1
and
3.
Your response
to this Notice is to be submitted in accordance
with the
provisions of 10 CFR 2.201 as stated in Appendix A, Notice of Violation.
En accordance
with 10 CFR 2.790(a),
a copy of this letter and the
enclosures will be placed in the
NRC Public Document
Room.
The response
directed
by this letter and the accompanying
Notice are not
subject to the clearance
procedure

Should you have
any questions
concerning this inspection,
we will be
pleased
to discuss
them with you.
