INSPECTION
REPORT 50-528/95-25;
50-529/95-25;
50-530/95-25
AND
This refers to the inspection
conducted
by Hr. K. Johnston
and other
inspectors
of this office on December
17,
1995,
through January
27,
1996, at
the Palo Verde Nuclear Generating Station,
Units 1,
2,
and 3, facility.
The
purpose of the inspection
was to determine
whether activities authorized
by
the license
were conducted
safely
and in accordance
with NRC requirements.
At
the conclusion of the inspection,
the findings were discussed
with you and
those
members of your staff identified in the enclosed
report.
Areas
examined during the inspection
are identified in the report.
Within
these
areas,
the inspection consisted
of selective
examinations of procedures
and representative
records,
interviews with personnel,
and observation
of
activities in progress.
Based
on the results of this inspection,
the
NRC has determined that three
violations of NRC requirements
occurred.
These violations are cited in the
enclosed
Notice of Violation (Notice)
and the circumstances
surrounding
them
are described
in detail
in the subject inspection report.
The violations
relate to issues
identified during
a review of the essential
chilled water
system.
The review focused
on the control of chiller refrigerant
and oil
levels,
and the control of essential
chilled water leakage.
Although the
three violations relate to the
same
system,
they highlight different
programmatic
weaknesses
that were identified throughout the assessment
of the
essential
chilled water system.
Violation A concerns
the failure to identify significant changes
in chiller
refrigerant
as
a condition adverse
to quality.
We are concerned
that
maintenance
personnel
corrected
an immediate deficiency without documenting
the problem
as required
by your prescribed
corrective action processes,
with
the result that you missed
an opportunity to assess
the potential
impact
on
system
performance
and operability.
Violation
B concerns
the failure to document
as
required
by your procedure,
when manual
actions
were
implemented
as
compensation
for a degraded
condition.
We are concerned
that this violation
apparently resulted
from weaknesses
in communications
between
the maintenance,
operations,
and engineering
organizations'602260377

Violation
C concerns
the failure to perform testing for emergency chiller
system leakage.
We are concerned
that engineering failed to communicate
recognized
design
and testing deficiencies to the operations
and maintenance
organizations
and failed to assure
that measures
were established
and
implemented within a reasonable
period of time to verify the continued
operability of the chilled water cooling system.
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.
Your response
may reference
or
include previous
docketed
correspondence, if the correspondence
adequately
addresses
the required
response.
After reviewing your response
to this
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
with 10 CFR 2.790 of the NRC's "Rules of Practice,"
a copy of
this letter, its enclosure(s),
and your response will be placed in the
NRC
Public Document
Room
(PDR).
To the extent possible,
your response
should not
include
any 'personal
privacy, proprietary,
or safeguards
information so that
it can
be placed in the
PDR without redaction.
The responses
directed
by this letter
and the enclosed
Notice are not subject
to the clearance
procedures
of the Office of Management
and Budget
as required
by the Paperwork Reduction Act of 1980,
Pub.
L. No. 96.511.
