Attention:
Mr.

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.
Rinqwald,
J.
Sloan,
and
P.
Narbut from May 27 through July 14
1990, of activities
authorized
by
NRC License
Nos.
NPF-51 and Nf'F-74, 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.
Mithin these
areas,
the inspection consisted of
selective
examinations of procedures
and representative
records,
interviews with personnel,
and observations
by the inspectors.
This report discusses
several
instances
in which operations
personnel
performance contributed to component operability problems or highlighted
areas
in which control
room practices
needed
improvement.
One of these
involved the manual mis-operation of an Atmospheric
Dump Valve (ADV)
despite
the significance of manual
ADV operation
as evidenced
in the
March 3, 1989, reactor trip event
and the several restart
commitments
associated
with manual
ADV operation.
Although the direct safety
significance of this event
was minimal, a violation is being cited for
thss matter
due to the repetitive nature of this issue.
Another instance
involved the inadvertent rendering of Safety Injection Tanks technically
by providing power to the vent valves.
These
events
and
others
described
in the inspection report reflect a need for greater
management
and supervisory attention to operator
performance.
