SUBJECT:
NRC INSPECTION
REPORT 50-528/94-15'0-529/94-15;
50-530/94-15
This refers to the inspection 'conducted
by Messrs. I. Barnes,
L. Ellershaw,
and
W. Walker of this office on April 19-29
and
May 9-13,
1994.
The
inspection
included
a review of activities authorized for your Palo Verde
Nuclear Generating Station,
Units 1, 2,
and 3, facility.
At the conclusion of
the inspection,
the findings were discussed
with those
members of your staff
identified in the enclosed report.
Areas
examined during the inspection
are identified in the report
and included.
a review of your steam generator history and material condition and inservice
inspection.
Within these
areas,
the inspection consisted of selective
examinations of procedures
and representative
records,
interviews with
personnel,
and observation of activities in progress.
The results of this
inspection
are documented
on page
2, in the enclosed report.
I
Overall, the results of the inspection indicate that you have
implemented
a-
comprehensive
eddy current examination
program for detection of degradation
in
steam generator tubing.
Other programmatic
actions
have also
been taken which
should
be beneficial
in terms of reducing the incidence of further tube
degradation.
Of particular
note
has
been the reduction in hot leg
temperature,
performance of chemical
cleaning of steam generators,
and the
implementation of various secondary
water chemistry initiatives.
While it is
acknowledged that improvements
in the chemistry information management
record
system are planned, it should
be noted that the existing system impairs the
assessment
of historical chemistry performance
and its possible contribution
tube degradation.
One other subject that we believe
warrants
management
attention is the identification of the contributory
reasons for variations in steam generator
tube degradation
rate
between the
three units and within each unit.
