NRC SPECIAL
INSPECTION
REPORT 50-528/94-23;
50-529/94-23;
50-530/94-23
This refers to the 'special
inspection
conducted
by H.
Wong and others,
of this
office and the Office of Nuclear Reactor Regulation,
on Nay 28 through
June
3,
1994.
The inspection
included
a review of activities authorized for
your Palo Verde Nuclear Generati'ng Station,
Units 1, 2,
and 3, facility.
At
the conclusion of the inspection,
the findings were discussed
with J.
Levine
and those
members of your staff identified in the enclosed
report.
Areas
examined during the inspection
are identified in the report.
The
special
inspection
reviewed the circumstances
of the Unit 2 reactor trip of
Nay 28,
1994,
and
assessed
the adequacy of the Arizona Public Service
Company's
response
to the event.
Within these
areas,
the inspection consisted
of selective
examinations
of procedures
and representative
records,
interviews
with personnel,
and observation
of activities in progress.
The purpose of the
inspection
was to determine
whether activities authorized
by the license
were
conducted
safely
and in accordance
with NRC requirements.
Based
on the results of this inspection,
certain licensed activities appeared
to be in violation of NRC requirements,
as specified in the enclosed
Notice of
Violation (Notice).
The violation and the issues
identified in the event
are
of concern
because
they highlight
a need to:
(1) reduce
personnel
errors,
(2) improve communications
between
maintenance
and operations
personnel,
(3) maintain
an effective questioning attitude,
(4) maintain
a "big picture"
view when responding
to plant conditions which are not understood,
and
(5) carefully assess
the "re-engineering"
changes
made to streamline your work
processes
to assure
that barriers
important to assuring
safety are not
removed.
We found your review of this event to be thorough
and
a high level of
management
involvement
was evident.
However,
from this event,
we are
particularly concerned
regarding
the mindsets of the instrument
and control

technician
involved in the work and the operators
responding
to the
rising'ontainment
sump level.
The instrument
and control technician
had
a mindset
regarding
the appropriate train of the containment
spray system
on which to
work.
The operators
had
a mindset that the valve in the correct train of the
containment
spray
system
had
been closed with power removed
and could not
be
causing
the
sump level rise.
These mindsets
contributed significantly to
causing this event.
Action is needed
to assure
that additional
mindsets
do
not cause other,
perhaps
more significant, events.
Additionally, program
changes
made to increase
work efficiency through your "re-engineering" efforts
must also balance
the
need to assure
that the sufficient safeguards'are
in
place for appropriate
control over the
new processes.
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.
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 and its 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 clearance
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,
8Y
