Attention:
Mr.

Executive Vice President,
Nuclear
Gentlemen:
SUBJECT:
NRC AUGMENTED INSPECTION
OF
PALO VERDE UNITS I, 2,
AND 3
This refers to the Augmented Inspection
Team (AIT) inspection
conducted
by
Messrs.
L. Miller, D. Acker, J. Sloan,
and
N. Trehan during the period of
November 16-19,
1991.
This inspection
examined
the partial loss of offsite
power event at Unit 3 which occurred
on November
15,
1991,
and other
activities authorized
by
NRC License
Nos.
51,
and 74.
At the
conclusion of the inspection,
the inspectors
met with Messrs.
J. Bailey,
i
. J. Levine,
and other members of your staff on November 20,
1991, to discuss
the findings 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.
Our inspection
concluded that this event occurred primarily due to:
(1) the
crane
being left unattended;
(2) failure of involved personnel
to electrically
ground the mobile crane
as required
by your accident prevention'anual;
and
(3) poor initial communication
between
the site of the event
and the control
room.
Many other factors contributed to the event.
Among these
were
inadequate
procedures for the safe operation of mobil'e cranes
near energized
equipment,
weak work planning
and control practices,
and excessive
work hours
for some of the personnel
working on this job.
Our inspection further concluded that your staff 's review of the lessons
learned for the Vogtle and Diablo Canyon loss of power events
had not been
effective in preventing this event.
Your responsible
line departments
had
reviewed their existing controls for operation of equipment
near energized
and transmission
lines,
but had not proposed sufficient revisions
to these controls to ensure
the safe conduct of switchyard activities.
It is particularly discouraging to note that this event occurred after
senior
NRC Region
V management
discussed
the Vogtle and Diablo Canyon events
with senior
APS management,
and
we were assured
that Palo Verde
had reviewed
and learned
from both of these
events.
Moreover,
as this report indicates,
in interviews with personnel directly involved in the event,
none of them
were aware of the Vogtle or Diablo Canyon events.

I encourage
you to thoroughly
and substantively
use the lessons
leaf ned from
this event
es
an opportunity to operate
more safely in the future.
<
The findings
and conclusions
of this inspection will be discussed
with you
as part 'of the previously scheduled
enforcement
conference
on December
18,
1991.
Enforcement actior if any, will be the sub'ect of separate
correspondence.
In accordance
with 10 CFR 2.790 (a),
a copy of this letter
and the enclosures
will be placed in the
NRC Public Document
Room.
Should you have
any questions
concerning this inspection,
we will be pleased
to
discuss
them with you.
Sincerely,
J.
B. Martin
