NOTICE OF VIOLATION AND NOTICE OF DEVIATION
NRC SYSTEM BASED INSTRUMENTATION AND CONTROL (I&C) INSPECTION OF
PALO VERDE UNITS 1, 2,
AND 3
NRC INSPECTION REPORT
NO. 50-528/529/530/92-14
Due to the recent loss of annunciator
event
and subsequent
Augmented
Inspection
Team at Palo Verde Unit 3, the scope,
number of inspectors,
and
time scheduled for this inspection
were reduced to 50X of the planned effort.
The depth
and scope of areas
inspected
were commensurately
reduced.
Areas examined during the inspection
are identified in the enclosed report.
Within these
areas,
the inspection consisted of examination of selected
procedures
and representative
records,
interviews with personnel,
and safety
system walk-downs.
The objective of this inspection
was to verify the functionality of safety
systems
by inspecting
performance related attributes of the system with a
focus
on its associated
instrumentation
and controls systems,
and the ability
of the system to perform its intended design function.
The team also
evaluated your I&C and setpoint programs,
and your commitments to these
programs.
Based
on the results of this inspection,
the team concluded that you have
recognized
the importance of I&C and setpoint
programs,
and that you have
taken positive steps
in improving your programs
by initiating a guality
Engineering technical
assessment
and
by taking appropriate corrective action.
The team also noted that the Palo Verde Business
Plan includes the support
required to continue your efforts within these
areas.
We consider your self-
assessment
efforts, your commitments to resolving identified problems,
and
your program improvement plans to be positive.
During the period of April 27 June
5,
1992, the
NRC conducted
a system-based
instrumentation
and control
(I&C) inspection of activities authorized
by NRC
licenses
and NPF-74.
The inspection
team included
M. Royack,
J. Sloan,
F.
Gee,
D. Acker, T. Sundsmo,
L. Coblentz,
and L. Tran of this
office, and L. King of the
NRC Region II office.
The team held
a discussion
of our findings with members of your staff at the conclusion of the inspection
on June 5, 1992.

However,
two of your activities appeared
to be in violation of NRC
requirements,
as specified in the enclosed
Notice of. Violation (Notice).
The
first violation involved failure to evaluate
and take adequate
corrective
actions for safety-related
and important to safet'y instruments routinely found
to be out of tolerance,
including the pressurizer
narrow range pressure
transmitters
and the emergency diesel
generator
trip switches.
The second violation involved failure of personnel
to follow
procedures
when performing instrumentation calibrations.
Additionally, one
deviation was identified involving operation of the
EDG air start
system at
a
lower pressure
than
used during system capacity tests
performed to demonstrate
compliance with Palo Verde Updated Safety Analysis design
assumptions.
Based
on the findings of inadequate
corrective actions in two different areas,
and the apparent
acceptance
of IKC technician supervisors that "skill-of-the-
craft" judgment
may supersede
procedural
requirements
in use of HLTE, we are
concerned
(1) that similar cases
of inadequate
engineering
evaluations
and
corrective actions for instruments
found out of tolerance
could be prevalent
throughout the units,
and
(2) that the
I&C technicians'ailure
to follow
procedural
requirements for HETE usage
could result in non-conservative
calibration of safety-related
instrumentation.
In your response
to the Notice
of Violation, we request that you include
an assessment
of these specific
concerns.
In accordance with 10 CFR Part 2.790 of the NRC's "Rules of Practice,"
a copy
of this letter and the enclosures will be placed in the
NRC Public Document
Room.
The response
directed
by this letter and the enclosed
Notice are not subject
to the clearance
procedures
of the Office of Hanagement
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 glad to
discuss
them with you.
