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, J.
Ringwald,
J.
Sloan,
D. Kirsch and
W.
Ang from January
6 through February
16, 1991,
of activities authorized
by
NRC License
Nos.
and to 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 representative
records,
interviews with personnel,
and observations
by the inspectors.
Based
on the results of this inspection, it appears that two of your
activities were not conducted
in full compliance with NRC requirements,
as specified in the enclosed
Notice of Violation (Notice).
In one case,
routine emergency
diesel
generator
(EDG) inspections
were performed
during plant operation,
which were not in accordance
with Technical
Specifications surveillance
requirements.
This appears
to be
a weakness
in your maintenance
scheduling process
which did not ensure
compliance
with conditions specified in Technical Specifications
and procedures.
It
also indicates
a need for increased sensitivity toward removing
safety-related
equipment
from service to perform maintenance.
The second
violation focuses
on the lack of an appropriate
technical
evaluation
for an air leak on the
EDG air start system to determine the potential
'impact on the air start system's ability to perform its safety function.
This seems to indicate
a need for heightened
emphasis
on thoroughly
evaluating deficiencies
on safety-related
equipment for design basis
impact.
Both these
examples
appear to indicate
a need for a more
critical and questioning attitude
on the part of your staff with regard
to maintenance
planning
and evaluations.
You are required to respond to this letter and should follow the
instructions specified in the enclosed
Notice when preparing your
response.
In your response,
you should document the specific actions

taken
and any additional actions
you plan to prevent recurrence.
As part
of your response,
please
provide your assessment
of the adequacy of
the evaluations
performed following identification of the
EDG air start system
leakage.
After reviewing your response
to the Notice, including your
proposed corrective actions
and the results of future inspections,
the
NRC will determine whether further
NRC enforcement action is necessary
to
ensure
compliance with NRC regulatory requirements.
In accordance
wit'h 10 CFR Part 2.790(a),
a copy of this letter and the
enclosures will be placed in the
NRC Public Document
Room.
The responses
directed
by this letter and the enclosed
Notice are not
subject to the clear ance procedures
of the Office of Management
and
Budget
as required
by the Paperwork Reduction Act of 1980,
Pub.
L.
No.96-511.
Should you have
any questions
concerning this inspection,
we will be
pleased
to discuss
them with you.
Sincerely,
