SUMMARY
Scope:
This was
a special
announced
Operational
Safety
Team Inspection.
This OSTI,
, utilizing
a
risk-based
inspection
guide,
evaluated
the
licensee's
current
level
of
performance
in
the
area
of plant
operations.
The
inspection
included
an evaluation
of the effectiveness
of various plant groups including
Operations,
Surveillance/IST/Calibration,
and
Administrative
Controls
and
Engineering
Support.
Plant
management's
awareness
of,
involvement in,
and
.
support of safe plant operations
were also evaluated.
The
inspection
was
divided
into
the
major
areas
of
Operations,
Surveillance/IST/Calibration,
and
Administrative
Controls
and
Engineering
Supports
The
team
placed
emphasis
on interviews of personnel
at all levels,
observations,
and
system
walkdowns.
The
inspectors
also
reviewed
plant
deviation reports,
LERs for current
SALP evaluation
period,
and evaluated
the
effectiveness
of the
licen'see's
root
cause
identification;
short
term
and
pro'grammatic
corrective actions,
and repetitive failure trendi'ng
and related
corrective actions.

Operations
(93802)
To
assess
the
operational
safety
of the facility, the
team
performed
extended
observations
of the control
room
and in-plant activities, with
one unit operating
steady
state
at
100 percent
power
and the other unit
returning
to
power
from
a
refueling
outage.
The
team
monitored
a
reactor
and
plant startup,
conducted
plant tours,
observed
operational
rounds
and shift turnovers,
and
reviewed
operator
logs.
In addition,
the
Operations
Supervisor,
licensed
and
non-licensed
operators,
and
shift technical
advisors
were interviewed.
The
team
also
reviewed
logs,
night orders,
and other selected
records
used
for indication
and/or
control
of plant
status
for adequacy,
and
verified operator
awareness
of their contents.
The
team
evaluated
operator
performance,
.control
room decorum,
awareness
of plant
status,
response
to alarms,
and
procedure
utilization.
The
team
also
reviewed
engineering
evaluations,
system
design,
equipment
maintenance,
operating
procedures,
and
operator training
as related to
questions that arose
from plant observations.
Control
room observations
The
shift
turnovers
observed
by
the
team
were
individual
(by
position)
and
informal.
There
were
no
formal shift
meetings
conducted
by
the
shift
supervision
to
ensure
that
all
crew
members,
including
NPOs,
SNPOs,
STAs,
chemistry,
and others,
were
aware
of
plant
status.
Pertinent
information
relative
to
outstanding
alarms,
on-going
work,
and
PWO
status
were
not
consistently
turned
over.
In general,
control
room
decorum
was
casual,
though
acceptable.
During
routine
evolutions
communications
were
informal,
in
that,
repeat-backs
were
frequently not utilized;
however,
there
was
no indication that the
information
was
not
being
received.
There
was
an
instance
where
the
control
board
operator
announced
to the
and
ANPS that
he
was
stopping
charging
pump
"A".
The
individual
looked
for
acknowledgement
from either
the
NPS or
ANPS;
however,
no
verbal
nor
non-verbal
acknowledgement
was
given.
During
complex
evolutions (i.e.,
the
turbine
over-speed
test
and
the
reactor
startup
on Unit-1),
communications
were
formalized.
Additionally,
the
ANPS
in the Unit-1 control
room displayed
good
control
and
focus of RTGB activities during
a reactor start-up.
On April 26,
1990,
the
ANPS
was closely monitoring control
rod manipulations
and
was
providing
effective
oversight
of
the
control
board
operator's
activities.
Control of access
to the
area
around
the control
boards
was
weak.
During
the first
week
of
the
inspection,
while
Unit I
was
performing
the initial
power
increase
after
the refueling,
there
were
fourteen
personnel
(at
least
four non-operations)
within the
area
of the
RTGB boards.
Although
signs
are
posted
stating
that
permission
is
required
for entry,
very
few
personnel
requested
permission.
The inspectors .noted that routine
access
is
not well
controlled.
This
was'videnced
when
five
- consecutive
non-
operations
persons
entered
the
.control
room
area
without
permission.
Additionally,
" the 'operators,
the
ANPS,
and
the
were facing the
and thus,
were not aware of these
individuals
nor their activities.
The
inspectors
also
noted that
hard
hats
were routinely worn in the control
room,
and
one
occasion
noticed
an
lean
over
the
RTGB several
times with his
hard
hat
on.
After this
issue
was
raised
with operations
management,
no other
individuals were observed
at the
RTGB with their hard hat on.

Plant

were
routinely
and
consistently
observed
in the plant.
The inspectors
noted
management
within the
control
room,
as well as,
in less traveled
areas.
The
number
and qualifications
of watch
standers
consistently
met
or exceeded
NRC requirements.
The personnel
on shift were clearly
posted
by position within each
control
room.
To the facility's
credit,

a

of the control
room,

by
performing
many of the
administrative
duties.
'The
NWE routinely
relieves
the
ANPS
and
assumes
the
command
and control
functions in
the
control
room.
In

The
NWEs
do
not routinely

maintain
an active license,
as defined
by
The licensee
needs
to administratively defined
the
NWE position to substantiate
that
the
NWE meets
the
requirements
of
a
TS defined
watch.
This
is considered
as
an unresolved
item (UNR 50-335,389/90-09-02).
The reactor
operators
and
senior reactor
operators
are
licensed
on
both
units.
The
reactor
operators
and
non-licensed
operators
rotate
between
units
on
a
frequent
basis.
However,
the
ANPSs
do
not
rotate
on
as
frequent
a
basis.
The
team
considered
the
rotation of the
and non-licensed
operators
as
a
good practice
to enhance
operator
awareness
of plant conditions
and
to maintain
proficiency
on
both
units.
The
ANPSs'otation
practice
was
considered

area
the licensee
may want to review,
in that,

would
be
rotated
to

as
a year.
away, with only one watch under instruction
on the "new" unit.
It appears
that
the
operators
have
become
desensitized
to
the
number of alarms
and
PWO tags
(48 in Unit-2) in the control
room,
as well as,
equipment
which is in the warning
range
by indication.
This situation
was
exacerbated
by the
high
number of
PWO tags
on
the
RTGB,
as well as,
the operator's
inability to obtain
the
PWO's
correct
status
from
NJPS.
This
system
is the 'only semi-immediate
mechanism
that
was
in
place
for
the
operators
to
obtain
PWO
status'owever,
the inspectors
identified that this
system is not
promptly
updated
to reflect
accurate
PWO status.
See
paragraphs
c. l., c.2.
and Appendix A for additional details.
The
operators
are
slow to acknowledge
the annunciator
alarms
both
when
the
alarms initiate
and
when they reset.
This
was primarily
observed
in Unit-1
on resetting
alarms
with the
large
number
of
alarms
annunciating
and resetting
during
the Unit start-ups.
The
inspector
attributes
this
to
the
audible
portion of the
alarms
which automatically
ceases
after 3-5
seconds.
As
a result,
there
is
no
urgency
on
the
part
of
the
operator
to
immediately
acknowledge
or reset
an

inspectors
noted
cases
where
an
alarm
would continue
to flash for five to
ten
minutes
after the alarm had reset,
without operator
acknowledgment.
There
were
only
i sol ated
cases
where
an
incoming
alarm
would
continue
to flash after
alarming for more than
one minute.
This
slow
acknowledgement
is
of
concern,
in that,
prompt
acknowl-
edgement
of
a potentially significant alarm could be'ecessary
to
mitigate or correct the alarm condition
Many of the
meter
faces
in the Unit
2 control
room are color coded
green/yellow/red,
signifying
normal/warning/alarm,
respectively.
However,
the color coding of the
meters
were
not consistent
with
the
actual
plant
conditions.
For
example:
on
the
circulating
water
pump
ammeters,
the
normal
readings
were
near
the high end of
the
yellow
range
on
the
meter
face,
with
one
meter
indicating
almost into the red.
The operators
were
trained
and
procedurally
.
instructed
to believe
indications
and
take
conservative
resultant
actions.
By routinely accepting
warning
and
alarm
indications
as
normal
or satisfactory indication,
the operators
become desensitized
to indications.
See
paragraph
3.d.
on
anomalous
indications
which
were not identified as abnormal.
In Unit-2,
a bearing
temperature
.alarm setpoint for the
IA reactor
coolant
pump
was, different
from the
identical
alarm
setpoints
on
the
other
reactor
. coo'lant
pumps.
The
reactor
operator
knew that
the
alarm setpoint
was
changed
to clear
the annunciator
window but
was
unable
to
determine
what, if anything,
had
authorized
the
'hange.
In fact,
the
change
was authorized
by
a maintenance
work
order
and
was
approved
by the
FRG.
The concern
of the inspector
was that the reactor
operator
did not
know what
had authorized
the
changing of the setpoint.
Evaluation of local plant operations
The
inspectors
routinely
toured
both
the
primary
and
secondary
sides
of the
plant
and
conducted
observations
of daily
rounds.
These
tours
and
observations
were
performed to identify potential
procedural
and
personnel
weaknesses,
as
well
as,
to
monitor
component/system
status
and performance.
During observation
of
NLOs performing daily rounds,
the operators
appeared
to
be
knowledgeable
with respect to'he
equipment
and
their respective
responsible
areas.
The facility has
three
levels
of qualification
for
the
NLOs,
with
the
most
senior
having
responsibility
for the majority of safety-related
equipment
needed
for reactor
protection.
During
the
plant
walkdowns
and
rounds
observations,
the following items/problems
were noted:
1)
Deficiency Tags
A large
number
of
PWO tags
existed
in both
the
respective
control
rooms
and
locally.
See
paragraph
2a.,
2c.,
and
Appendix A for details.
Housekeeping
General
housekeeping
appeared
to
be
adequate.
However,
the
inspector
noted
various
locations
within Unit-1
where
housekeeping
appeared
to
be
weak
(e.g.
trash,
booties,
gloves,
consumable
material,
etc.,
on
floors/equipment).
Recognizing
the
unit
was
restarting
from
an
outage,
the
inspector
re-evaluated
these
areas
at
a
subsequent
date.
With
exception
of
. the
rooms,
the . inspector
noted
expected
improvement.
In
the
rooms,
the
inspector
identified
numerous
housekeeping
items
such
as:
trash,
oil
leaks,
can
of anti-seize,
rags,
tape,
sandpaper,
etc.
The
inspector
noted
that
painting
was
occurring
in
the
rooms,
and
most of these
items
could
be attributable
to the
painters.
However,
stronger
control
is
needed
over their
activities.
This
is
further
exemplified
by
the
fact that
upon
subsequent
re-inspection
of
these
areas,
similar
housekeeping
items
existed.
Additionally,
the
inspector
identified
that
the
operating
procedure
had
been
removed
from its
location
on
the
local
panel
and
placed
on
the
third tier of steps
going
over
the diesel.
Evidently, its
rack
had
been
removed
for
painting,
making
the
procedure difficult to locate
during
an
emergency.
The
painting
crew
did
not
recognize
the
importance
of this
procedure
nor the necessity of having it readily accessible.
The inspector
also
noted that the
EDG barring device for the
1B2 diesel
was
placed
on the
EDG fuel oil
day
tank.
Normal
storage
location
is
under
the
EDG steps.
This
item is of
concern,
in that,
during
an
EDG start
or
a
seismic
event,
this
heavy
tool
could
possibly
brake
'the
day
tank
level
indicator
and/or
the oil
day
tank
level
alarm
indicator
switch
LIS-59-016B,
as .well
as,
lo-lo alarm indicator switch
LIS-59-017B.
This could result in loss of alarm for the
day
tank level'n the control
room.
Tran s i ent
Combu st ib1 es
While
performing
a
plant
walkdown,
the
inspector
observed
combustible
paint thinner left in
two
open
buckets
while the
painting
crew
was
apparently
at
lunch.
There
was
unused thinner being stored in approved containers.
J
However,
"used"
thinner
was
left
in
the
open
buckets
approximately
one-foot
from
the
1A
fuel oil flexible
Section
8.2'.5.
of
Administrative
Procedure
0010434,
Revision
22,
Plant
Fire
Protection
Guidelines,
states
that
combustible
material,
unless
stored
in approved
containers,
shall
not
be left unattended
during
lunch, shift changes
or any time for more
than
30 minutes."
As this
appeared
to
be
an isolated
occurrence,
this issue
is
only being
addressed
as
a
weakness.
When
the situation
was
brought
to
the
licensee's
attention,
the
condition
was
promptly corrected.
Local Alarm/Annunciator Testing
During
a
plant
tour with
one
NLO, it
was
noted
that
the
local
alarm
panels
were
not periodically
lamp
tested
(as
with
the
control
room
panels).
When
this
condition
was
brought
to
the
attention
of
operations
management,
the
operations
supervisor
recognized
this
testing
omission
as
an oversight.
It was
entered
in the night order
book
as
an
addition to the shiftly surveillances
for the
NLOs.
Industrial Safety
It appeared
that
the
licensee
has
an
aggressive
personnel
safety
program.
Safety
requirements
and
reminders
are
conspicuously
posted
throughout
the
site.
Compliance
with
safety
practices
appeared
to
be
good.
However,
at various
times
personnel
were
observed
not
utilizing
hearing
protection
in posted
areas.
The
inspectors
observed
routine
and
prudent
safety
belt
usage,
with
the
only
exception
being
an
individual
working
on
top
of
a
heater
with no safety belt.
Danger
Tags
The
inspectors
discovered
a
Danger
Tag (021) associated
with
clearance
number
1-5-106
in
a
cubicle
on
the Unit-1 Waste
Panel.
This
tag
was
evidently
detached
or
had
fallen
from 'its
location
and
was
placed
in this
cubicle
versus
returning it to the control
room.
It appeared
to
be
an
isolated
instance
as
no
other
examples
were
found,
and
this tag
had
been verified as
being properly
hung three
days
earlier.
The
inspectors
noted
on April
24,
1990,
that
the
Unit-1
Boric
Acid Control
Panel
contained
12
PWO
tags,
each
of
which
described
a
related
equipment,
panel
hardware,
or
operating
discrepancy.
During
a
walkdown with
an
RO,
the
RO understood
the significance
and operational
limitations of
each deficiency described
on the respective
PWO.
The
was
also
able
to
walk
the
inspector
through
local
alternative
methods of panel operations.
Further discussion
with the operator
revealed that the
number
of
problems
identified
on
the
panel
could
make
efficient
operation
difficult, especially if the
operator
was
not
proficient in panel
operations

Room
During the
course
of the
inspection,
the
inspectors
noted
a
high
number
of
PWO
deficiency
tags.
Specifically,
on
April 25,
1990, there
were
48
PWO tags
on the Unit-2
RTGB and
27
PWO tags
on Unit-1's
RTGB.
The high number of tags is not
a
problem
in
and
of itself;
however,
some
NPWOs
have
been
outstanding
since
1988.
While the
inspectors
noted that the
number
of
PWO tags
in the control
room
had
been
decreasing
since
the first of the year,
there
are still
a
number
of
identified equipment
concerns.
As
detailed
below,
the
operators
are
not
consistently
cognizant
of
NPWO
status
nor
are
they
able
to
accurately
extract
this
information
for
NJPS.
The
operators
did
not
routinely
turnover
NPWO
status;
the
inspectors
identified
that the operators
often did not
know the status/operability
of
the deficient
equipment.
As
a result, it appeared
the
operators
have
become
desensitized
to
the
number
and
status
of PWOs
~
Additionally,
there
were
instances
where
tags
were
hung,
when
the
PWO
was
completed.
This,
coupled
with the
high
number
of
PWO
tags,
could
be
distracting
or
misleading
for
equipment
operation
during
a
transient/emergency.
The
controlling
procedure
fo'r the.
PWO
tagging
processes
is

Revision
41.
A
walkdown
was
performed
on
May
10,
1990
of
the
Unit-2
control
room
comparing
a
tagging
printout
versus
control
room tag status.

The
status
of
the
above
five tags
is
not critical
as
the
work
had
been'ompleted.
However,
on
May
10,
1990,
these
NPWOs
were listed
as
ready
to
be
worked
when
in fact
they
had
been
worked
six to
seven
days earlier.
The
NJPS
system
is not promptly
updated,
and
is
the
only
immediate
method
the
operators
have
available
for deficiency
status.
By not
having
an
accurate
status
available,
the
. potential
exists
for misleading
an
operator
as
to
what
equipment
has
been
fixed
and
is
actually
available
for
support
of
normal/emergency
operations.
See
paragraph
C.2.
and
Appendix
A for
additional
details
and
examples
of this
problem.
There
were
three
PWO
tags
located
in the control
room which
did'ot
have
the
proper
"C" designation,
as
required
by
Section
B.2. 11
of
AP-001043
and
thus
were
not routinely
checked
for tag
status.
These
PWOs
included:
PWO
6081
(XA
900408200606)
PWO
6315
(XA
900504215725)
PWO
6306
(XA
900507103018).
There
was also
an
instance
where
the
PWO
had
been
canceled;
yet
the
tag
remained
inside
the
(Tag
C32069).
The
only
information
available
to
the
operator
from
NJPS
was that this
PWO
was
canceled.
The operator
has
no alternative
means
by which to verify whether
the
tag
is
valid.
Subsequent
to
the
walkdown,
a
new
PWO
was
generated
for this
item.
The
above
examples
indicate
a failure to
follow procedures.
This
is
considered
to
be
an
apparent
violation (VIO 50-335,389/90-09-01).
Emergency

During
a
walkdown
of the
Unit-2
on
May 8,
1990,
the
inspectors
compared
a
current
listing
of
active
PWOs
(obtained
from
NJPS
in Unit-2 control
room) to status
in the
field.
Section

the

PWO 5057
(XA

was
statused
on

as
being
ready
to
be
worked.
However,
the
work
completion
and
tag
removal
evidently
occurred
on
May
2,
1990.
Subsequent
to
the
inspection,
tags
43110
and
43788
were
removed
and apparently
the
IEC supervisors
were instructed to review the
requirement
to remove tags
subsequent
to work completion.
10
Additionally,
the
licensee
stated
that
subsequent
to
the
inspection,
"I 5
C training
has
been
sent
a
memo to include
this
item in their periodic training for journeymen."
These
tags
would have
been
removed if the
requirement
for attaching
the tag to the applicable
NPWO (section
8.6.9 of AP-00143)
was
observed.
However,
neither
plant
NPWO tags
nor control
room
tags
are attached
to
NPWOs as required.
In
summary,
these
. discrepancies
(identified
above)
are
significant
based
on
the fact they demonstrate
a significant
deficiency
in
the
tagging
process,
as
well
as,
making it
difficult for
operators
and/or
maintenance
personnel
to
ascertain
whether
or not
equipment
is deficient.
This
could
'otentially
to operation
of defective
equipment
and/or
non-operation
of equipment
which is actually fully operative
(due
to
a
tag
which
was
not
removed).
Based
on
the
above,
this
item 'is
considered
as
further
examples
of
apparent
violation 50-335,389/90-09-01

Surveillance
Testing
The
inspection
team
reviewed
the
p'rocedures
for and monitored the
operations
and
I8C department
perform surveillances
'on
( 1) channel

and

of the
Reactor

All
of
the
survei llances
were
performed
satisfactorily
and
in
accordance
with
the
respective
procedure.
There
were
two
surveillances
(discussed
below)
in
which weaknesses/discrepancies
were identified by the inspectors:
1)
Engineered
Safeguards
Systems
On
May
9,
1990,
the
inspector
witnessed
the
channel
functional
testing
of
Engineered
Safeguards
System.
This
testing
was
performed
in
accordance
with
18C
Procedure
2-
1400052,
Engineered
Safeguards
Actuation
System
-
Channel
Functional
Test,
revision
16.
This test
was
professionally
conducted
by
skilled
I&C 'echnicians,
with
no
test
anomalies
identified.
The
technicians
were
cognizant
of the
potential
impact
of
improper
test
performance
(i.e.
safeguards
actuation
or
potential
trip)
and
were
very
conscientious
in
procedural
adherence,
as
well
as,
anticipatory
of any
expected
annunciations/alarms.
One test
weakness
was
observed
however,
in that,
the
control
board
operators
and
the
technicians
performing
the test
were
not
verbally
communicating
prior
to
test-induced
alarm
annunciation
on the
RTGB.
When
the
inspector
questioned
the
operator
as
to
how
he
knew that
the
functional
testing. was
the
alarms'/source,
he
stated
that
he
expected
safeguards
alarms
since
he was aware the test
was being conducted.
11
Upon
discussion
with
other
operators,
they
informed
the
inspector
that
other
redundant
indication
was
available
to
indicate
that
the
alarm
was
test-induced.
The
operator
acknowledging
the
alarms
agreed
that this verification, with
other
indications,
should
be
accomplished
prior
to
alarm
acknowledgement.
Additionally,
the
inspector
questioned
why
the
operator
could
not informally follow the
expected
alarm
sequence
in the
procedure,
or
more closely
communicate
with
the
technicians
during
the
testing.
Subsequent
to
this
discussion,
the
IEC technicians
performing
the test
gave
a
verbal
warning
to
the
control
board
operator
prior
to
generating
an alarm.
The inspector
noted
a strength
during the test,
in that,
one
of the
technicians
routinely conducts
the
Unit-2 safeguards
channel
functioning
testing.
As
a
result,
he
was
very
familiar with test
methodology,
as
well
as,
test
sequence.
This practice
should
preclude
most
problems
encountered
due
to
inexperienced
test
personnel
and
also
increased
test
efficiency.
The
inspectors
noted
that
during
performance
of the
monthly
NI
calibration
that
the
technician
and
the
operators
effectively
communicated
throughout
the
test.
The
technician
alerted
the
operators,
to
alarms
prior to
initiation
and
the
operators
routinely
acknowledged
this
communication
when
the
alarms
annunciated.
During
the
NI
calibration,
the
18C supervisor
noted that
one of the
meters
did
not
return
to
normal
indication after
the calibration
and
stopped
the
technicians
from
proceeding.
He
notified
the
ANPS
and
recommended
a
PWO
be initiated to correct
the
problem
prior to
continuing
with
the
calibration
of
the
other channels.
Auxiliary, Feedwater
System
During
an
evaluation
of the
records
associated
with Unit
1
initial
startup
from
the
1990
refueling
outage,
the
inspector
reviewed
the April 13,
1990,
Period
Test",
Operating
Procedure
1-070050,
Revision
29.
During this
evaluation,
the
inspector'oted
that
discharge
pressure
generated
by
the
1C
(SDAFW)
pump
was
1350
psig.
The
TS
required
minimum
pressure
per
4.7. 1.2 a.2.
is
1342
psig.
Due to the
small
degree
by which the
pump
passed
its
surveillance,
the
inspector
inquired
as
to
the
discharge
pressure
gauge's
(PI-09-7C)
accuracy.
PI-09-7C
is
a locally
mounted,
2500
psig,
Ashcroft
Duragauge
pressure
indicator
with
a
plus
or minus
.5 percent
(12.5
psig)
accuracy.
The
inspector
attempted
to verify that
this
plus
or
minus
.5
percent
instrument
accuracy
was
included
in the
TS
value
of
1342
psig,
as
the
pump
may
have
been'roducing
only
1337.5
psig
discharge
pressure
when
a
conservative
error
(-12.5
psig)
was taken into account.
12
The inspector
was
informed that the
TS
minimum value of 1342
psig
includes
a
10.9
percent
margin
from
the
applicable
accident
analysis.
Pe'r
a
memo
from
JPN
to the site,
"This
10.9
percent
margin
more
than
accommodates
for
the
1/2
percent
instrument
inaccuracy
associated
with the
local
1C
pump
discharge
pressure
gauge".
'The
inspector
agreed
that
even
at
1337.5
psig
the
accident
analysis
could easily
be
met.
However, it was
not determined
whether
or
not
the
pump
actually" developed
greater
than
1342
psig
discharge
pressure
as
required
by
TS.
The
inspector
questioned
the
lack
of
administrative
margin
between
the
TS
and
the
periodic
test
and
noted
that
the
Unit
2
periodic
test
contains
a
minimum discharge
pressure
which is greater
than
that of TS.
Upon
review of the
pump's
performance
for the past year
and
five
months,
it
was
noted
that
the-
discharge
pressure
developed
during
the
April
13,
1990,
test
was
the
lowest
over that time interval.
The
inspector
then
reviewed
the calibration
records
for the
instrument
subsequent
to its
replacement
in. December
1988.
On January ll,
1989,
the
read
from
5 to
15 psig
high
on all
but
the
bottom
(0 psig)
and full scale
(2500
psig)
calibration
points.
In less
than
one
month,
the
had
exceeded
its plus or minus
12.5
psig
tolerance
for
two test
points.
The
only
adjustments
made
to
the
were
to
bring the
two test points to 2.5 psig within tolerance (i.e.
as=fourid
indicated
15
psig
high, as-left indicated'0
psig
high).
On April
11,
1989,
the
was
again
found to
be
out of tolerance
at. two test points
(15 psig high),
and
was
adjusted
to read
0 psig to
10 psig
low
on all
but
one test
point (as-left
for this
point
was
plus
5 psig).
In less
than
five months
from installation,
this
exceeded
its
specified
accuracy
prior
to
two
calibrations
(only
three
months
apart).
The
required calibration
frequency
is
an
18
month interval.
On April 2;
1990,
the
was calibrated
with the
greatest
differential
between
desired
output
and
actual
at
plus
10
psig.
This test
point
was left "as-
found".
However,
When
thi s
point
was
left
at
plus
10
psig
on
January
11,
1989,
three
months
later it
had
exceeded
its
plus or minus
12.5 psig tolerance.
As
a result of the
above,
three
weaknesses
associated
with the
Periodic
Test
and
the
were identified.
The first and
second
related
to the
test itself,
in that
the
pressure
(20 psig
increments)
can
only
be
read
to
the
nearest
10
psig
mark.
The
test
specified
1342
psig
as
the
minimum acceptable
value which is
difficult to discern
from the
Associated
with this
inability to
read
this specific
value,
is
the fact that
on
the calibrations,
the
is
sometimes
read
to
the
5 psig
increment.
13
The
second
weakness
is that
the
surveillance
test
does
not
contain
an administrative
margin
from the
min.imum
TS value.
As
discussed,
Unit-2
TS
does
contain
an
administrative
margin
as
does
standard
industry
practice
in
this
area.
The'hird
weakness
is that
the
technicians
performing
the
calibrations
often
do
not
adjust
the
toward
the
desired
pressure,
i.e.
the
is often left at
the
"as-
found"
reading,
thus
eliminating
the
amount
of margin
for
drift/change
between. calibrations.
In
summary,
the
degree
and
frequency
by which this
has
consistently
read
high
.during
calibrations,
coupled
with
non-conservative
calibration
practices,
does
not
provide
a
high degree
of confidence
that this
gauge will maintain its
specified
accuracy
between
tests
and/or
calibrations.
Additionally,
the
concern
is that
at
the
lower
discharge
pressures
(e.g.
1350
psig)
the
pump
may
not
be
actually
generating
a
discharge
pressure
greater
than
1342
psig,
as required
by TS.
Additionally,
the
Unit-1
turbine
test
was
well
coordinated,.
with
effective
communications
(repeat-backs)
within the
control
room with activities
in the
control
room
being
well
controlled
during
the
test.
This
item
is
considered
as'n
inspector
follow-up
item
(IFI
50-
335,389/90-09-04)
Interviews
The control
room operators
stated
during interviews that
some
would
go
an entire shift without entering
the control
room unless
specifically
called.
Discussions
with the
supervision
and
operations
supervision
indicated
that
the
STA is
by design,
an
independent
entity,
and that
do
go into
each
control
room
periodically during the shift.
There is not
a requirement
for the
STA to enter
the control
room,
only that
they
be
aware
of plant
status.
The
problem
may
be that
the
STA is
in fact,
performing
the
appropriate
duties
and
routinely entering
the
control
room.
However,
the visibility of the
STA may need to be heightened.
During
the
interviews
with
licensed
and
operators,
the
inspector
asked
questions
of
the
operators
to
determine
their
ability to
use
the
off-normal
and
emergency
procedures.
The
operators
demonstrated
adequate
procedural
knowledge
with
one
exception.
Two of seven
operators
incorrectly
used
the Diagnostic
Flow Chart
contained
within EOP-l,
"Standard
Post
Trip Actions".
The diagnostic
flow chart
in
EOP-1 is not consistent
with the
Owners'roup
guidance
shown
in
CEN-152,
Revision
3,
"Combustion
Engineering
Emergency
Procedure
Guidelines",
with respect
to the
transition
to the
FRP if the reactivity control
safety
function is
not
met.
The
licensee's
basis
for the difference
was
acceptable
and was addressed
in training.
14
However,
two operators
did not
use
the
flowchart correctly
when
placed
in
a scenario

an oversight
had occurred,
in that,
the, responsible
department
heads
were not being notified of the
needed

had
been
recently audited
by the site quality assurance
department
(Audit

Over time
The inspectors
verified that Operations
management
is'ognizant
of
excessive
overtime utilization
and
pre-approve
excessive
overtime
when
required.
The
inspector
reviewed
overtime pre-authorizations
dated January
20,
1989,
and January
29,
1990,
to verify a proactive
cognizance
of
excessive
overtime.

and
this aspect
was not reviewed during this inspection.
h.
Critical Systems
Monitoring Parameters
The
licensee
has
instituted
a
mechanism
by
which
to
monitor
critical
system
parameters
for
possible
trends.
This
system
trends
such
parameters
as:
bleedoff
flow,
containment
particulates,
RCS,
leakage,
bearing
temperatures,
condenser
backpressures,
charging/letdown
mismatch,
and
HX differential
pressure.
This
system
has
proven
beneficial
to
the
licensee,
in that 'they
have
been
able
to Inonitor
and
prevent
potential
component
fai lures/intolerabilities.
For
example,
a
trend
with
Unit-2
2A2
RCP bleedoff
flow had
shown
an
increasing
trend
from
March
2 to April 21,
1990,
thus allowing the operations
department
time
to
examine
potential
root
causes
and
applicable
corrective
action -on
a
more
proactive
basis.
The
inspector
considered
this
program
to
be
a strength
and exemplifies
proactive
involvement in
equipment/plant
performance.

Licensed Operator Requalification
paragraph
55.59(a)(2)
requires
licensed
personnel
to
participate
in requalification
and
to participate
in the
annual
examinations.
In 1988
and
1989,
three
licensed
personnel
from the
training staff were
exempted
from all or portions of the required
examinations,
based
on participation
in
the
preparation
and/or
administration
of
the
examinations.
Although
the
facility's
current
program
may allow. this,
"Answers to Questions
at
Public Meetings Regarding
Implementation of Title 10,
Code of Federal
Regulations,
Part
55
on Operators'icenses",
Question
345
(pg

states,
in part:
"... will the
who writes
the
performance
exam,
and is thus
exempt
from taking the
exam for that
'ear,
comply with this [55.59(a)(2)]
requirement?"
Answer -" it is
the
Commission's
intent that all licensed
operators
be enrolled in
the
requalification
program
and
take
the
requalification
exams;
further,
an individual must take
an
exam that
he did not write or
review."
Specifics
of
the
exemptions
for. personnel
who
passed
licensing
examinations
during
that
year;
who
did
not
take
the
requalification
exams is listed as'ollows:
1)
Trainer
A
in
1988,
exempted
from the operating
portion of
the
examinations
based
on
participation
in
the
development
,and administration of those
exams.
2)
Trainer
B -
in
1988,
exempted
from all
portions
of the
examinations,
written
and
operating,
based
on participation
in the
development
and- administration
of the
exam.
In 1989,
exempted
from
the
written
examination
and
the
walkthrough
part of the
operating
examination
based
on participation
in
the
development
and
review
of
the
examinations,
and
administration of the walkthrough portion.
3)
Trainer
C - in
1988,
exempted
from the operating
portion of
the
examinations
based
on
participation
in
the
development
and
administration
of the
exams.
In 1989,
exempted
from the
written
examination
and
the
walkthrough
part
of
the
operating
examination
based
on
participation
in
the
development
and
review
of
the
examinations
and
administration of the walkthrough portion.
The
licensee's
practice
of
allowing
licensed
personnel
who
participate
in all
phases
of the
requal
exam
process
to
be
exempted
from portions
of the
exams
does
not
meet
the intent of
10 CFR 55 paragraph
55.59 (a)(2)
and
as further interpreted
by
answer
to
question
number
345.
The
licensee
needs
to
strengthen
administrative
guidance
in this area
prior
to the
next
requal
exam.

The inspector'as
informed
that
the
procedures
were
generally
performed
in
the

Due
to
the
awkward
nature
of
the

The inspector
was
informed that specialists

and flow rates
were not measured
during the last Uni,t

outage.
The
check
valve test
has
been
replaced
by check
valve
disassembly.
The
explanation
of
the
widely varying
flow rates
was that
the
conditions
such
as
refueling cavity level
and
SIT pressure
would
cause
the
changes
in the flow rates'he
inspector
observed
that
for identical conditions, the flow rates
varied
by as
much
as
2873
gpm
( 1596
gpm
vs.
4496
gpm).
The
inspector
questioned
the
technical
adequacy
of
the
licensee's
explanation
which did
not
appear
to
satisfactorily
explain
the
differences
in
the
flow
rates.
The
inspector
discussed
the rational
for the differences
and the
licensee
agreed
that there
were
no reasonable
explanations
for
the
data
recorded.
Additionally,
the
records
for
this
procedure
were difficult to retrieve
from
document
control,
in
that it required
the
test
engineer
to
provide
the
test
dates
before
document
control
could
retrieve
the
records.
The
information
stored
in
document
control
was
not
sufficient
to
provide
qualitative
or
a
quantitative
explanation
for the
flow
rates
recorded.

and
discussed
the
calculation with plant engineering
and
the
AE that
generated
the
calculation.
The
calculation
was
based
upon
a
containment

temperature
of
85
degrees
and
was
only val"id at that point (reference
assumption
5.5
and
step

The

calculation
applied
the
temperature
bias
as
an
independent
variable,
in that it was
included
in
the
borated
water
density
correction.
The
calculation
reached
an
appropriate
conclusion
that
the error
was plus or minus
3. 1 inches.
The
85 degree
was arbitrarily
chosen
to provide
a
range for the error contribution for the
Rosemont transmitter,
and although
a value of
75
degrees
may
have
been
more
appropriate,
the operational

The operations
personnel
used
a
"cheater

in
an
attempt
to correct
the
errant

There
was
no
procedure
for closing this limitorque valve
in this
manner
using
this
method.
It
was
impossible
to
determine
the actual

of this action.
Without inspection, it may
be
impos'sible
to determine
the effect
on
the valve's

The
licensee
responded
to the
inspectors
question,
by issuing
a-
standing
night

which
stated
that
"the
use
of valve

should
only
be
used

The night order further
stressed
the
importance
of

appears
to have
recorded
a governor rack position for both the
12 cylinder
and the
16 cylinder diesels,
these
positions

100 times
the
normal
value, it appears
to be
a misplaced decimal.

The diesel
generator
average
cylinder
temperature
decreased
(4.3
degrees)
during the run.
The inspector
was informed by the
system engineer that this
change
was
due to the
inaccuracies
of the diesel

and
was
not
caused
by
reduction
of

There
was
a differential temperature

the inspector
was
informed that this
was
an
acceptable
band
for the differential

the

engineer
identified
the

This information
was
included
in

Page
33 of 33 this procedure

appears
to
have
recorded
VARS instead
of
MVARS.
Based
on
the rise of average
cylinder temperatures
(6.65
'egrees)
of the
12 cylinder diesel it appears
that
the
turbo

temperature
should
have
been
higher
(reference
the

performance
under similar circumstances
in which
a
5 degree

for
the

was
28.5
degrees
higher
than
the

The
inspector
was
informed that
these

were
not
indicative
of

but
were
the
result
of
unrelated
physical
parameters
such
as

The poor quality of recorded
data
in this procedure
demonstrated.
that the

Administrative Controls
and Engineering
Support
The
Independent -Safety
Engineering
Group at the St.
Lucie Nuclear
Power
Plant
was
established
in accordance
with the
requirements
specified
in
Their function
as
specified
by TS 6.2.3. 1
is
to
examine
plant
operating
characteristics,
NRC
issuances,
industry advisories,
Licensee
Event
Reports
and
other
sources
of
plant
design
and
operating

information,
including
plants of similar
design,
which
may indicate
areas
for improving
plant
safety.
The
ISEG organization
consists
of
a
chairman
and
four
ISEG engineers,
which is the
minimum
complement
of personnel
requi'red
by
technical
specifications.
In
order
to
accomplish
their assigned
mission
the
group reviews various
forms of industry
operating
experience
to determine
what problem areas
may exist at
ST.
Lucie.
From this
review,
the
chairman
assigns
projects
to
each
of
the
ISEG
engineers
for
investigation.
These
'nvestigations
take
the
form of
one
of three
types:
1)
ISEG
Evaluations,
which
are
large
scope
investigations
similar to
a
SSFI,
2)
ISEG Surveillances,
which
are
smaller
in
scope
and
may
consist
for
example
of
a walk down of
a safety
system,
or 3)
ISEG
Independent
Verifications,
which
are
even
smaller
in
scope
requiring
approximately
a
day
or
two to accomplish.
Note:
The
ISEG
chairman
has
recently
discontinued
the
Independent
Verification
type
of project
arid
plans
to
issue
this
type
of
project in the future as
ISEG Surveillances.
During this inspection
an overall
assessment
of the
performance
of
the
ISEG
was
conducted
by the
inspection
teams
This
assessment
concluded
that
the
group
has
a limited
impactg on
improvements
in
plant
safety.
This
conclusion
is
based
on
the
following
observations:
The
ISEG is staffed with only the, minimum compliment of personnel
required
by technical
specifications.
Productivity within
the
group
needs
improvement.
The
average
project takes
approximately
three
months
to accomplish
and
issue.
One project
reviewed
( ISEG Evaluation
ISE-87-005)
on the
Emergency
Diesel
Air Starting
System
took
approximately
eight
months
to
accomplish,
and
another
eight
months
to
issue
the
report.
This
evaluation
was
similar
to
an
of
the
EDGASS,
and
was
accomplished
by
one
individual.
The length of time to accomplish
this project indicates
that the project
scope
was too large to
be
adequately
accomplished
by
one
individual.
Historically,
the
group
has
accomplished
about five to
seven
projects
per year
per
ISEG engineer.
27
Additionally, the last
ISEG Evaluation
was
issued
October 31,
1989,
the last
ISEG Surveillance
was issued
January
12,
1990,
and the last
ISEG Independent Verification was issued April 12,
1989.
At the
time
of this
inspection,
the
ISEG
had
a total
of
48
recommendations
outstanding.
Of these,
18 were
over
one year old.
The
age of these
items
was attributed primarily to the lack of an
aggressive
ISEG
program
in
obtaining
corrective
actions
from
various
plant- organizations.
Memoranda
forwarding
the results
of
ISEG
evaluations/survei llances
and
independent
verifications
do
not
require
a
written
response
from
the
responsible
plant
organization,
which firmly establishes
a corrective
action
plan,
and
a
time table for accomplishments
Additionally,
ISEG does
not
have
a
program or policy implemented,
which formally documents
and
follows corrective
actions
through completion.
As
a result,
there
is
a
lack of organized,
detailed
documentation
concerning
the
current
status
and
closeout
of deficiencies.
The
only practical
way to determine
the
status
of an outstanding
item is to discuss
the
item with the
responsible
ISEG engineer.
The development
and
implementation
of the
ISEG
Follow-up Status
System
was
the
only
positive
aspect
to
a
very
weak corrective
action
program within
ISEG.
The
IFUSS is
a computerized
tracking
system
for outstanding
ISEG
recommendations,
which
provides
a
quick
reference
to
the
status
of items.
Monthly
IFUSS
reports
have
been
issued
to
the
plant
manager
and site
vice president
for the last year.
These
status
reports
do
provide
some
added visibility to'utstanding
ISEG items.
The
new
ISEG chairman
had
recognized
a
number of these
weaknesses
prior
to
this
inspection.
Several
corrective
actions
were
completed,
during
the
inspection,
to
improve
performance.
These
included
revision
to
the
appropriate
ISEG
administrative
procedures .to require written
responses
from the plant for
ISEG
category
1
and
2
items
(NRC
concerns
and
safety
significant
deficiencies).
The
corrective
action
plans
and
commitment
dates
for category
3,
and
below,
items continue
to
be the responsibility
of the
ISEG engineer.
The
chairman
committed
to establishing
a
corrective
action
section
in all. future report files,
and
he also,
committed
to the
update
of all files with
open
items,
with the
corrective
<<action
documentation
that
is
available.
The
implementation
of
these
actions
and
improvement
in overall
ISEG
performance
is identified
as
inspector
follow-up
item (IFI
50-
335,389/90-09-7).
The
Facility
Review
Group
at
ST.
LUCIE
was
established
in
accordance
with TS 6.5.
The function of the
FRG is to advise
the
plant
manager
on all matters
which relate to nuclear
safety.
The
chairman
of the
FRG is the plant
manager
and
members
are
from the
various
disciplines
within the
plant staff.
To
accomplish
its
mission
the
FRG
reviews
the
various
documentation
concerning
the
activities which are important to safety at the site.
Oocumentation
includes for example
procedure
changes,
TS changes
and any violations
to TS, modification packages
and
LERs.
28
In order to have
a voting quorum to accomplish its assigned
mission,
at least five
FRG members
must
be present,
and
no more than
two of
these
members
can
be designated
alternates.
Minutes of all meetings
.
are
recorded
and distributed
to document
the activities of the
FRG'n
accordance
with TS 6.5. 1.8.
During this inspection
the
performance
of the
FRG was
reviewed
by
the inspection
team.
The activities
of the
FRG
were
reviewed
by
attendance
at
two
FRG meetings,
and
by review of meeting
minutes
for
approximately thirty meetings.
Overall,
the
performance
of
the
FRG was
considered
to
be excellent.
The
FRG is very active at
the site,
and
an
average
of approximately
two meetings
per, week
are
conducted
to
review plant activities.
A meeting
agenda
is
prepared
by the
FRG secretary,
and
items
which require
some
time
to review are distributed to
members
in advance
of the meeting
to
allow for detailed
review.
The
meetings
are
very
informal
and
discussion
of
safety
issues
are
very
open
and
relevant
Participation
by all
members
was very active.
The
FRG also
has
a
policy of not
reviewing
new activities
unless
the
sponsor
of the
activity is
present
to
answer
al,l
FRG questions
on 'the
subject.
The
informality of
the
meetings,
and
lack of attention
to the
meeting
minutes
did
,
however,
to
several
concerns
by the
inspection
team
which, if corrected,
would
improve
overall
performance:
During
the
meeting
on
May
8,
1990,
LER 335-90-05
concerning
a
problem
with
the
electrical
breakers
on
the
Emergency
Diesel
Generators
was
presented
to
the
FRG
for
approval.
Several
comments
on
the
technical
content
of
the
LER
were
provided
separately
to
the
LER
sponsor
by
several,FRG
members
before,
during
and after the
FRG meeting.
No vote
on approval
of the
LER
was
taken
during the meeting
by the alternate
FRG chairman.
After
the
meeting
the
inspection
team
question
whether
or not
the
LER
had
been
approved
by the
FRG.
The
team
was
informed that the
LER
had
been
"approved with comments",
which meant that the
LER would
not receive
any additional
review by the
FRG.
It was
noted
by the
inspection
team that
no listing of the
problems with the
LER was
compiled
by the
FRG
and
no
FRG
member
was
assigned
to ensure
that
all
FRG issues
were resolved.
Therefore,
the only person
who
new
the
extent
of all of the
comments
was
the
LER sponsor,
and
no
follow-, up
by the
FRG
was initiated
to
ensure
resolution
of all
issues.
This is considered
to be extremely poor practice.
A distinct difference
in
the
area
of
item
approval
was
noted
between
the. meeting
conducted
by the
chairman
on April 26,
1990,
and
the alternate
chairman
on
May 8,
1990.
The
chairman
asked,
for
each
item,
whether
the
FRG
members
had
any
problem
with
approval
of th'e
item.
The alternate
chairman
took
no
such
vote
on
the
items
in the
May 8,
1990.,
meeting.
Failure to take
some
sort
of vote
on
each
issue
is
considered
to
be
a
week
practice,
especially for items
where
there is
an extensive
discussion
of the
item.
Review of meeting minutes
noted several
weaknesses:

'1)
Meeting

This
is
the
case
even
concerning
meetings
which
are
not

and
approved
by
at
least
one
FRG
member,
who
understands
the
technical
issues
discussed
at
the
meeting
and
who attended
the meeting.
This is necessary
in order to
verify that
the
minutes
reflect
what actually
occurred
at
the meeting.
Meeting
minutes
are
not distributed
in
a
timely fashion.
Review of this
area
noted that
minutes
for
32 site
meetings
remain
undistributed
over
one
month after
the
meetings
were
conducted.

The weakness
in the

reviewed
by
the
inspection
team
to evaluate
the
implementation
of the
licensee's
program.
This
was
accomplished
by
review
of
the
licensee's
evaluation
and corrective
actions
for
a
sample
of several
IEBs,
LERs,
and
Generic
Letter s.
This
review
concluded
that
the
licensee
has
an
adequate
program
to
address
these
issues.
No
weaknesses
were identified.
The
items
reviewed
and
the details of
the reviews are
as follows:
1)
LER
89-007,
Unit
2:
This
LER discusses
a
manual reactor trip which
was
initiated
on
September
23,
1989,
due
to
a
dropped
CEA in
one
group,
followed
by four dropped
CEAs in
another
group.
Recovery
from this trip was
complicated
by
inadequate
performance
of
a
steam
bypass
control
valve,
failure
of 'one
of
the
Auxiliary
flow control
valves,
and
failure
of
the
on
another
control
valve.
The
team
reviewed
the
results
of
the
in-
house
investigation
of
the
problems
encountered,
which
caused
the trip, 'and
the
problems
experienced
in recovery
from the trip ~
The investigation
of all of these
problems
was
thorough
and
in
all
cases,
except
the
steam
bypass
valve
problem,
identified the root cause
of each
problem.
The unsatisfactory
performance
of the
bypass
valve -could not
be duplicated after
the trip recovery
was completed.
Corrective actions
to correct
the
immediate
problem
and
to .prevent
similar
problems
were,
adequate.
The
inspection
team
focussed
on
the
retesting
of
components
after completion of maintenance
work.
Adequate
post
maintenance
testing to verify operability was accomplished.

LER
89-007,

This
LER reported
a violation of the
one
hour time limit for bypassing
a failed 4160V channel,
in
accordance
with
~ 1
action
12,
when it failed its
monthly
surveillance.
The
problem
was
caused
by
inadequate
procedures
for
bypassing
the
affected
channel.
The
inspection
team
reviewed
the
revised
procedure,
and verified
that
the
other unit
had
been
reviewed
for similar existing
conditions.
LER
89-009,
Unit
2:
This
LER
reported
that
containment

isolation
valve
FCV-25-5
had
failed its
local
leak

test
on
November

team
reviewed
the
licensee's
corrective
action.
Emphasis
was
placed
on
ensuring
that
th'e
testing
frequency
(which
has
been
increased
to
every
six weeks),
and
interim corrective
actions
as
specified
in the
LER were
being maintained.
This
action
was being
performed
in accordance
with the
licensee's
commitment.
Permanent
corrective
action for this'eficiency
is
scheduled
to
be
completed
during
the
upcoming
Unit
2

LER
88-008,
Unit
1:
This
LER
reported
on
September
20,
1988.

was
also
connected
to
this
terminal;
but
was
not

from the wire being'removed.
As
a result,
the
power

The
licensee's
corrective
action
was
to
place
all
multi
wire

connections
in
the
SGFRS
into
common
lugs
to
prevent
inadvertent lifting of leads.
The
inspection
team
verified
that
this
action
had
been
accomplished
on
both
units
by
inspection of the hardware
in the plants.
Failure

Plugs:
This
IEB
required
licensees
to
investigate
and
evaluate
certain
lots
of
defective
Tube Plugs.
The- licensee
had
investigated
the
use
of
these
plugs
at
St.

had determined
which plugs required
removal,
and
had
remove
the
plugs during
two separate

removal
and
replacement,
by review of the
completed
work packages
for this work.

PWO/JO
7843/61
(XA 880914031912);
P-57 is
locked
in
when
the
fan is running:
This
PWO
was written
on
September
14,
1988,
and
parts
were
ordered
November
3,
1988,
t'o rectify the discrepancy.
After
discussions
on
May 8,
1990,
with maintenance
personnel,
the
inspector
determined
that this part
had
been
received
on site,
and
was awaiting
P-57
is
the
Containment
Airborne Activity
Removal
Fan
(HUE-1)
flow low/motor
over load
alarm.
This
item is
a
concern,
in that,
for approximately
16
months
operators
did not
have
complete
indication
available
for
low flow nor
a
motor
overload
condition
on HVE-1.
The
commercial
grade dedication
group
was effective
January
1,
1990.
However,,this
part
has
been de-prioritized.
Due to
the length of time this condition has
been
present,
the potential
exists
for de-sensitization
to the discrepant
condition by the operating
crew.
PWO/JO
7841/61
(XA880910143426);
Level
indicator
alarm for. Boric Acid
Make-up
Tank
1B Level: This
PWO identified that
RTGB indicator
LIA-2208
disagrees
with local
indication
LT-2208
by
5 percent.
The
PWO also
identified
that
the
instrumentation
is
TS
instrumentation
and
that
"accuracy
is
very
important".
On
September
16,
1988,
the
licensee
determined
that the
on the local level transmitter
(LT-2208)
was
reading
high
and
could
not
be
adjusted
within the
manufacturer's
specifications.
On October
27,
1988,
an In-plant Requisition/Stores
was
generated
for
a
new
meter kit assembly;
evidently this
meter kit
assembly
was not subsequently
ordered
nor received.
On April 18,
1990,
(approximately
18
months later),
the
assembly
was reordered.
There is
no
documented
evidence
that correct
action/follow-up
was
taken
during
the
18
month
interval.
Additionally,
the
deficiency
tag
(C29547)
associated
with this
PWO was
located
on the
RTGB versus
locally, which
is where
the discrepant
indication
was
located.
When questioned
by. the
inspectors,
the operator
at
the
controls
was
not
aware
that
the
indication
was
accurate
and
was apparently
mislead
by the
improper
tag
location (i.e.
tag was not hung locally).
This
18 month delay with no corrective
action is significant,
in that,
it is
indicative
of
a
lack of .aggressive
PWO
follow-up/statusing.
Additionally,
the
operator
was
not
aware
of
the
details
of
the
discrepancy
and did not
know his
RTGB indication
was
adequate.
He
was
also
unable
to discern this
information
from
NJPS.
The
operators
may
have
become
desensitized
to this condition
due to the approximately
19
months it had been
open.
PWO/JO
6252/62
(XA890514212343);
Window for fuel
pool
flow
Hi/Lo:
This
PWO
requested
investigation/repair
as
the
was alarming with good flow.
On
May 16,
1989,
attempts
were
made
to correct
this condition.
However,
the
PWO stated
that
an
"REA
needs
to be written to install dampers
in line to eliminate pulsations".
The inspector
questioned
as to the REA's status
and
was informed that
on
May 9,
1990,
an
RFD was initiated as the
REA was never written.
Appendix A
This 'approximate
one year delay in follow-up is indicative of a lack of
aggressive
follow-up and statusing
of
PWOs.
Additionally, the operators
may
have
become
desensitized
to this alarm
as
the
PWO tag
on the
was

4 ~
PWO/JO
6631/62
(XA 890804124015);
Window for
RWT level
Hi/Lo:
This
PWO
was written
as
the
alarm
was
apparently
in for
no
reason.
On
August
14,
1989,
relay
71X
was
replaced
which corrected
alarming
condition.
However,,
due
to
operating
constraints,
the
low
level
alarm could not
be tested.
When
an operator
was questioned
as to
the reason
why the annunciator
had
a deficiency tag
on it, the operator
stated
that
the
condition
had evidently cleared.
While attempting
to
verify
PWO status
on
NJPS,
the
status
was listed
as
a
code
45 (i.e.
ready to
be worked).
The operator
was not aware of the maintenance
that
had
been
performed
and
had apparently
not questioned
the status
of the
deficiency
during
any
shift
turnovers
nor
while
on
shift.
This
situation is of concern,
in that,
while other indication
was available,
had
the
come
in during'
low-level
condition,
the
operator
could
have
been
temporarily mislead
into believing
the
alarm
was in for no reason.
PWO/JO
6079/62
(XA900408174151);
This
PWO was written on April 8,
1990,
to address
the fact that the
number
9 bearing
on the main turbine
was in
alert
due
to vibration.
This condition
was
tagged
on
the
RTGB (back
panel).
An
18C technician
validated
the
alarm
on April 17,
1990,
and
was
awaiting
a
new
setpoint
from
Engineering
when
evidently,
the
condition
cleared;
the
PWO
tag
was
subsequently
removed.
The
alarm
returned
at
a later date,
and the
PWO was
held open to troubleshoot
the
problem.
During
a walkdown on April 24,
1990,
the inspector
noticed
the
alarm
and
inquired
as
to
why there
was
not
a
PWO tag identifying the
alarm
condition.
The
operator
questioned,
did
not
know
a
PWO
was
currently
open
addressing
the condition,
nor did the operator
conduct
a
search
on NJPS.
The inspector
then
accompanied
an
18C technician
to the
local Bentley-Nevada
Monitoring device to validate the alarm.
This item is of concern,
in that,
the operator
at the controls did not
know how long the alarm
had been
in, nor did
he attempt
to utilize
NJPS
for status.
Additionally, the
PWO tag
should
have
been
re-hung
when the
alarm
condition
reappeared
or
when
the
next
walkdown
(by
the
operators)
was
conducted
during
turnover.
This
is
an
example
of
desensitization
of operators
to plant conditions/alarms
and demonstrates
the
need
for
increased
cognizance
of
PWO
status
during
turnovers.
Subsequent
to the inspector questioning
PWO tag status,
the tag was re-hung.
PWO/JO
6672/61
(XA 90041?180952);
This
PWO tag identified that
there
were
no audible
alarms
on the Unit-1
panel
106.
This-PWO was
generated
on April 17,
1990,
and
completed
(including
post-maintenance
testing
on April 20,
1990.
On April 24,
1990,
the inspector
questioned
the operator
as to the status
of alarm availability;
the
operator
was
initially unaware
that
the
problem
had
been
corrected.
This
item
demonstrates
a lack of sensitivity
on part of the
operators,
in that,
this
condition
was
evidently
not
discussed
during turnover,
and
the
operator
was
unaware of whether
he
had
ECCS audible alarms available.
ll
I
l
< J
Appendix A
'3
This
PWO is
an additional
example
of the
need
to discuss
PWO status
during turnover
and to have
a correct
and
updated
PWO status
available
to the operators.
PWO/JO
5274/62
(XA 880915085631)
and
PWO/JO
5640/62
(XA 890226173942);
these
two
PWO's identified deficiencies
associated
with circuit 43 motor
for the
125 volt DC Buses
2A and
2B.
These deficiencies
resulted
in the
inability to operate
the
125
V
OC buses
transfer
breakers
from the
keyswitch operator.
This item is significant, in that,
the
125 volt OC bus
2A key was in the
keyswitch
and
according
to the
ANPs, this keyswitch could
be utilized
even
though
the deficiency
tag
(C 29175)
stated
that it did not work.
The
ANPS
was
concerned
as
the other
keyswitch
had the
key
removed with
no
power indication
(2B bus).
However,
the deficiency
tag
(C
323164)
associated
with this keyswitch contained
the
same
wording
as
the other
tag.
Thus, it was potentially confusing to the operators
whether or not
the
keyswitches
worked,
and
whether
or
not
they
could
believe
the
deficiency tags'nformation
Subsequent
to
the
inspection,
the
inspector
spoke
via
telephone
communication
with the Electrical
Maintenance
Supervisor
and
an
NPS;
Evidently,
at
the
end
of
the
inspection,
neither
keyswitch
worked.
However,
one
key
was in the respective
keyswitch
and the
ANPS believed
it did,
in
fact
work.
Evidently,
the
deficient
condition
was
temporarily corrected
in the past
which misled the
ANPS into believing
one
keyswitch worked.
This is another
example of old
PWOs,
the status
of which
operators
were
unaware
of,
and
as
such,
were

PWO/JO
5606/62
(XA 890907081845);
Reset
switch
rotates
freely
and
breaker will not
close.
This
PWO identified that
the
switchgear
breaker
TCB-5 would not close
locally
and that
the
reset
switch rotated 'freely.
This
PWO was worked
on
September
7,
1989.
The
work performed
included
replacing
the closing coil
and
damaged
latch
r'elease.
The
breaker
was
functionally tested
and
was
released
to
operations.
The
NPS Notification of Completion
was
signed
later
the
same day.
On
May 8,
1990,
the
inspector
noted
that
the
reset
switch
had
a
deficiency
tag
(C41183)
located
next to it stating
that
the
switch
rotates
freely.
However,
on
September
7,
1989,
the
switch
had
been
repaired.
This
PWO has
been
kept
open for tracking
purposes
only.
This
item is
of
concern,
in that,
the
condition
on
the
tag
has
been
corrected,
but the deficiency description
on the tag
was incorrect for
eight
months
since
the
switch
was fixed.
One operator
questioned
did
not
know that
the
switch
had
in fact
been
fixed
and
apparently
took
credence
in
the
tag's
deficiency
description
when that condition
no
longer existed.
While witnessing
packing repairs
to the
1C charging
pump,
the inspector
noted
a
PWO tag
(number
unknown)
hanging
on the
pump's
seal
tank.
This
tag stated
that the annunciator
for the
seal
tank does
not work.
This
item is another
example of inconsistent
tagging practices.

The annunciator
identified
on the tag is evidently the
however, it was
tagged locally at the
seal
tank versus
the
RTGB.
This
tag location is critical, in that, if the
tag
was actually for the
the operators
did not .have
a
method of annunciation
to
know
whether or not
seal
tank level
was acceptable.
Low seal
tank level is
indicative of an excessive
