Nuclear Regulatory
Commission Inspection
Report 50-250,251/96-04
This integrated
inspection
was conducted
by the resident
and regional
inspectors
to assure
public health
and safety. It involved direct inspection
at the site in the following areas:
plant operations
including engineered
safety features
walkdowns, operational
safety;
and plant events;
maintenance
including surveillance observations;
engineering;
and plant support including
radiological controls,
chemistry, fire protection,
and housekeeping.
Backshift inspections
were performed in accordance
with Nuclear Regulatory
Commission
inspection guidance.
Within the scope of this inspection,
the inspectors
determined that the
licensee
continued to demonstrate
satisfactory
performance to ensure
safe
plant operations.
The inspectors
identified the following one cited
and two
non-cited violations,
and
one inspector followup item.

Outside the Radiation Controlled Area (section
R1.2)
During this inspection period, the inspectors
had
comments
in the following
functional
areas:
Plant
0 erations
Unit 4 mode changes
and startup
from the refueling outage
were all well
performed with noted strong oversight
and very good communications
(section 01.1).
Safety
system
walkdowns of the
common high head safety injection system
and the Unit 4 emergency diesel
generators
noted satisfactory
alignment.
Specific minor labelling
and material condition issues
were
appropriately
addressed
(sections
02. 1 and 02.2).
An issue regarding charging
pump response
on
a safety injection (e.g.,
the
pumps
are tripped
and locked out for two minutes)
was
an inspector
followup item (section
03. 1).
Weaknesses
were identified relative to the condensate
polishing
demineralizer
system procedures
and safety analysis description
(section
03.2).
~
Failure to follow the Chemical
and
Volume Control
System operating
procedure
during
a Unit 4 blender flushing evolution was
a cited
violation (section
04. 1).
~
Operators
appropriately
and conservatively
made
a decision to trip Unit
4 following plant response
to an increase
in generator
load due to
turbine governor problems.
Operator response
during startup following
the reactor trip was cautious,
deliberate,
and well supervised
(section
04.2).
~
Management's
self-assessment
capability relative to Unit 4 startup
readiness
was noteworthy (section
07. 1).
~
The on-site
and off-site safety committees
and the quality assurance
organization
were functioning well and were focused
towards nuclear
safety (section 07.2).
~
An open item regarding
was closed
(section
08.01).
~
Operator
response
to
a Unit 3 loss of the
3C bus
was very good,
including initiating a manual reactor trip.
However,
enhancements
were
needed
in the loss of C bus off-normal operating
procedure
(section
M1.4) .
~
An 'excellent questioning attitude exhibited
by a Nuclear Plant
Supervisor led to the identification of a problem associated
with the
cross-connecting
of two safety
buses
during outages
was considered
a
strength
(section
E2.2).
Maintenance
For the Unit 4 outage
maintenance
work activities observed,
the
inspectors
found that detailed
procedures
were in place
and were being
followed.
Work activities were being performed in accordance
with
requirements
by knowledgeable
and qualified personnel
in a professional
manner (section Ml.1).
The Flow Accelerated
Corrosion
program
was working well and the process
for evaluation
and disposition of results
was identified as
a strength
(section M1.2).
Except for a weakness
associated
with one radiographic technique,
performance
associated
with safety-related
welding was good.
Personnel
were well qualified and work was well documented.
Weld quality was
determined
to be good (section M1.3).
Unit 4 maintenance
testing activities resulted
in
a Unit 3 manual trip
when the
3C bus
was lost.
Root cause
was inadequate
design of the
3C
bus floor (metal
deck plates).
Root cause
analysis
and corrective
actions
were thorough,
prompt,
and effective (section M1.4).
Appropriate actions
were initiated to address
related
concerns
applicable to main turbine maintenance
that were
identified following a reactor trip (section Hl.5).
Unit 4 rod testing following a manual trip demonstrated
adequate
drop
times with no observed
rod recoil.
Good test coordination
was also
noted (section
H2. 1).
heater related
issues
caused
a Unit 4 power reduction (section
H2.2).
Unit 4 integrated
safeguards
testing
was well performed.
However,
an
instrumentation
and control error during test
setup
caused
an engineered
safeguards
features
actuation
(section
H3. 1).
The post maintenance
testing
program was functioning well (section
H6.1).
En ineerin
The licensee
demonstrated
effective control
and conduct of the Unit 4
startup
and physics testing
program (section El. 1).
The licensee
appropriately
addressed
and dispositioned
a switchgear
stationary switch failure, including generic
issues
(section
E1.2).
Identification
of the vulnerability during nitrogen
and water fill
evolutions to the cold leg accumulators
was
a strength
in the operating
experience
feedback
program (section
E2. 1).
Failure to consider the effects of cross-connecting
480 volt load
centers
during safety evaluations
performed in 1988
and
1989 was
a non-
cited violation (section E2.2).
Continued attention related to Emergency
Containment
Cooler reliability
was warranted
(section
E2.3).
Periodic
and special
reports
(licensee
event reports)
were well written
and appropriately
submitted
(sections
E3. 1 and E3.2).
Updated final safety analysis report reviews detected
several
errors
(section
ES. 1).
Plant
Su
ort
Radiation protection
and health physics
performance
during the Unit 4
refueling was very good.
Performance
goals
were met including radiation
dose (section Rl, 1).
The discovery of a contaminated flashlight outside the radiation
controlled area
was
a non-cited violation (section R1.2).
NRC was conservatively
and appropriately notified of a non-credible
bomb
threat (section Sl. 1).
The licensee
appropriately
responded
to and reported
event (section S1.2).

Summary of Plant Status
Unit 3
At the beginning of this reporting period, Unit 3 was operating
at or
near full reactor
power and
had
been
on line since February
22,
1996.
The unit was manually tripped
on March 27,
1996 when the
3C 4KV bus
was
lost (see section M1.4).
The unit restarted
on March 28 and went on-
line March 29,
1996,
(section
04. 1).
The unit operated
at or near full
power the remaining portion of the inspection period.

At the beginning of this repo} ting period, Unit 4 was in the cycle
16
refueling outage
which began
March 4,
1996.
The unit restarted
on
April 6,
1996
and went on-line April 8,
1996.
The cycle
16 refueling
outage lasted 35'ays.
An overspeed trip test
was satisfactorily
performed
and the unit was placed
back on-line April 9,
1996.
During
turbine power increase,
a manual trip was initiated in response
to
abnormal
turbine generator
response
(sections
04.2
and M1.5).
The unit
restarted
on April 10,
1996.
On April 18 and 21,
1996,
the unit was
operated
at reduced
power
(90X and
60K) to accommodate
troubleshooting
and repairs
on the feedwater
heater
system
(section M2.2).
The unit was
returned to
100X reactor
power on April 22,
1996.
On April 29,
1996,
the unit was reduced to 60X as
a precaution to repair
a
SGFP suction
pressure
switch.
The unit operated
at or near full power for the
remainder of the inspection period.

60710,
71707,
71711,
73753,
92901,
and
93702)
The inspectors verified that the licensee
operated
the facilities safely
and in conformance with regulatory requirements.
The inspectors
accomplished
this by direct observation of activities, tours of the
facilities, interviews
and discussions
with personnel,
independent
verification of safety
system status
and technical
specification
compliance,
review of facility records,
inspections
of outage
activities,
and evaluation of the licensee's
management
control.
The
inspectors
also reviewed activities associated
with restart
from
refueling.
The inspectors
reviewed plant events
to determine facility status
and
the
need for further followup action.
The significance of these
events
was evaluated
along with the performance of the appropriate
safety
systems
and the actions
taken
by the licensee.
The inspectors verified
that required notifications were
made to the
NRC and that licensee
followup including event chronology, root cause determination,
and
corrective actions
were appropriate.
The inspectors
performed
an inspection
designed
to verify the status of
the Unit 4 emergency diesel
generator
and
common
HHSI systems.
This was
accomplished
by performing
a complete
walkdown of all accessible
equipment.'he
inspectors
reviewed
system procedures,
housekeeping
and
cleanliness,
major system
components,
valves,
hangers
and supports,
local
and remote instrumentation,
and component labelling.
The inspectors
also performed
a review of the licensee's
self-assessment
capability by including
PNSC
and
CNRB activities,
QA/QC audits
and
reviews, line management
self-assessments,
individual self-checking
techniques,
and performance
indicators.
In addition,
the inspectors
reviewed
one previous
open item to assure
that corrective actions
were adequately
implemented
and resulted
in
conformance with regulatory requirements.

02.1
Conduct of Operations
Unit 4 Mode Changes
and Startup
Unit 4 transitioned
from Mode 6 to Mode
1 during the period March 29 to
April 8,
1996.
The unit achieved criticality at 3: 16 a.m.
on April 6,
1996,
and was placed
on line April 8,
1996.
This ended the Unit 4 cycle
16 refueling outage.
The outage
was originally scheduled for 32 days
and
was completed
in 35'ays.
Following completion of the turbine
test,
the unit was placed
back online on April 9,
1996.
However,
a manual trip was initiated during
an unexpected
turbine load
increase
(sections
04.2
and M1.5),
The inspectors
noted that the Unit 4 outage
delays
were caused
by crane
problems
(see
NRC Inspection
Report 50-250,251/96-02),
ECC valve issues
(section E2.3),
and turbine oil
FME issues
(e.g
~ , rag found in the
bearing oil eductor
and corrosion of an oil orifice).
Notwithstanding
these
delays,
the licensee
demonstrated
conservatism
and aggressiveness
in dealing with these
issues.
The inspectors
observed
portions of the startup activities,
power
ascension,
turbine testing,
and other related activities.
The
inspectors
noted strong oversight
and good communication
and concluded
that the Unit 4 startup
was professionally
conducted.
Operational
Status of Facilities
and Equipment
Units
3 and
4 High Head Safety Injection Systems
Walkdowns
The inspectors
performed
a walkdown to verify the status of the Units
3
and
4 HHSI systems.
This was accomplished
by performing
a complete
walkdown of all accessible
equipment,
The following criteria were used,
as appropriate,
during this inspection:
system lineup procedures
matched plant drawings
and as-built
configuration;
appropriate
levels of housekeeping
cleanliness
were being
maintained;
valves in the system
were correctly installed
and did not exhibit
signs of gross
packing leakage,
bent stems,
missing handwheels,
or
improper labeling;
hangers
and supports
were
made
up properly and aligned correctly;
valves in the flow paths
were in correct configuration;
local
and remote position indication was compared,
and remote
instrumentation
was functional;
major system
components
were properly labeled;
surveillance testing procedures
and activities were appropriate;
and
maintenance activities (past, current,
and planned)
were
appropriate.
The inspectors
concluded that the Units 3 and
4 HHSI systems
were
satisfactorily aligned for normal
and
emergency operation.
Hinor
labelling
and material condition deficiencies
were discussed
with
engineering,
operations,
and maintenance
personnel.
The walkdown also
verified the completion of the Unit 4 BIT bypass modification (see
NRC
Inspection
Report 50-250,251/94-04,
section
E2.3).
The BIT and related
equipment
have
been
abandoned
in place.
The inspector
noted that the
affected
equipment
was not marked
as such.
The licensee
stated that
they would address
this issue.

Unit 4 Emergency Diesel
Generator
Walkdown
The inspector walked
down
a significant portion of the Unit 4 Emergency
Diesel
Generator
System,
including the fuel oil system,
cooling water
system,
lube oil system, air start system,
and electrical
system for the
4A and
4B EDGs.
The walkdown included observation of system material
condition,
open maintenance
work requests,
housekeeping,
valve
alignment, and'lectrical
breaker alignment.
For the portions observed,
the inspector did not observe
any
abnormalities
associated
with the system or the system drawings that
were
used for the system walkdown,
The inspector
concluded that system
configuration
was appropriately maintained.

Operations
Procedures
and Documentation
Charging
Pump Response
During Safety Injection
As followup to the manual
Unit 4 trip on April 9,
1996,
(section 04.2),
the inspector
reviewed
EOP adequacy
and charging
pump effects.
The
resultant
cooldown
and decrease
in pressurizer
level
caused
a letdown
isolation at
14%.
Operators
had already
responded
by starting
a third
pump (two charging
pumps
were already running).
As pressurizer
level
approached
12% (12.4% was the lowest recorded value),
the control
room
licensed operators,
management,
and the
actuation criteria as delineated
in emergency
operating
procedure
4-EOP-
E-O, Reactor Trip or Safety Injection, foldout page step
No. 5.
This
step required
a manual
(based
on CETs)
was less
than 30'F'r if pressurizer
level could not be maintained greater
than
12%.
Based
on cooldown being controlled with the MSIVs closed,
and
pressurizer
level being restored with charging,
and greater
than
12%
level,
manual
SI was not required
and therefore
was not initiated.
At Turkey Point, the
HHSI pumps are designed
as
1600 psig discharge
pumps.
Therefore,
there
are
no
RCS operating
pressure
pumps.
(A
manual
or automatic
SI signal trips all operating
and available charging
pumps.)
The charging
pumps are therefore unavailable for at least
2
minutes, until SI can
be reset
per procedure
4-EOP-E-0 step
16,
and
charging is re-established
per step
41.
The inspector
expressed
concern that charging would be lost to recover
pressurizer
level in the case of a manual
SI.
The inspector
noted this
issue
was also raised at the
PNSC post-trip review meeting.
Licensee
actions
were to make
an
open item (PMAI) to initiate
a
REA
investigation.
Further,
the inspector reviewed the
UFSAR to confirm the
charging
pump trip design
on SI.
UFSAR sections
reviewed included 9.2
(CVCS), 6.2
(ECCS),
14. 1.5
(CVCS Malfunction),
and
14.3
(RCS Pipe
Rupture).
Section
14.3, 1 stated that the charging
pumps
have the
capability to make
up for RCS leakage
from ruptures of small cross
sections,
permitting
an orderly shutdown.
Based
on the above,
the inspector
considered this issue to be
an
inspector followup item.
The item will be tracked
as IFI, 50-
250,251/96-04-01,
Charging
Pump
Response
During SI.
Condensate
Polishing Demineralizer
System
On April 12,
1996, during
a periodic plant tour, the inspector
noted
abnormal
conditions at the Unit 4 condensate
polishing system control
room and control panel.
The conditions included
a high
DP alarm for an
inservice demineralizer,
instrumentation
OOS,
poor material condition,
and weaknesses
in procedure
OP-7001.3,
Condensate
Polishing System-
Powdex Vessel
Operation.
The licensee
only uses this system following a
refueling outage with the unit shutdown or at low power,
and not as
a
full flow system.
Only
a portion of the condensate
system is diverted
through the polisher system.
UFSAR section
10.2,
stated that the condensate
polishing demineralizer
system treats full flow from the condensate
pumps
(pages
10.2-8
and
10.2-3).
The licensee
has
had previous plant trips due to loss of
condensate
and feedwater flow from this system.
As
a result,
the system
is only operating
in a "Kidney Loop" (e.g., diverted flow) method.
The inspector
informed licensee
management
of these
issues.
The
licensee initiated condition report No.96-596
and immediately corrected
the abnormal
conditions.
Operations,
chemistry,
and management
personnel
were responsive
to the inspector's
concerns.
Plant personnel
were already in the process
of revising the
OP.
Other corrective
actions
included addressing
the material condition deficiencies,
submitting
an
UFSAR change,
and informing plant personnel
of those
issues.

04.1
The inspector
concluded that weaknesses
existed in the operating
procedure
and
UFSAR description for the non-safety related
condensate
polishing demineralizer
system.
Operator
Knowledge
and Performance-
Chemical
and
Volume Control
System Operation
On March 28,
1996, Unit 3 was restarted
from a manual trip (section
Ml.4).
During control
room observation of startup activities,
the
RCO
momentarily aligned the
CVCS system in a configuration not described
in
procedure
3-0P-46,
Control.
At the time, the
RCO was periodically borating in accordance
with section 5.2, Boration,
of procedure
3-OP-46 in order to compensate
for Xenon burnout.
Following one
such boration,
the
RCO manually opened
valves
3-113B and
3-114A such that primary water was aligned through the blender
and
directly to the suction of the charging
pumps.
This was done to flush
out the boric acid from the blender following the boration.
This
alignment
was momentarily maintained until approximately five gallons of
primary water flowed through the blender.
Procedure
3-OP-46
has
provisions for dilution through two flow paths.
The preferred
path is
through the blender
and to the
VCT.
An alternate dilute path which
simultaneously
aligns primary water to the
VCT and directly to the
charging
pumps
can also
be used
as described
in section 5.3, Dilution,
of procedure
3-OP-46.
However,
opening valves
3-113B and 3-114A to
flush the blender
was not specifically described
in procedure
3-0P-46.
Further,
UFSAR section
9.2 only addressed
boration,
normal dilute,
alternate dilute and did not address
this "flushing" evolution.
Procedure
steps
involving boration or dilution did not require signoffs.
Further,
procedure
3-OP-46
was not required to be open (i.e., referred
to during performance of boration or dilution) to perform these
frequently performed evolutions.
The inspector discussed
the issue with the
RCO, the ANPS, the Operations
Supervisor
as to the need for this alignment
and whether the
RCO was
aware that flushing/diluting via valves
3-113B and 3-114A was outside
the scope of the
CVCS procedure.
The
RCO and the
ANPS had not
considered
the procedural
scope
when performing this evolution.
Apparently,
in the past,
the Turkey Point boric acid system
was designed
for highly concentrated
During this time, flushing the
blender with primary water following boration
was
common practice
procedurally to ensure
the blender did not crystalize with the boron.
However, with the boric acid system currently designed for approximately
2000
ppm, the need for flushing the blender
does not exist.
The inspector
co'nfirmed th'rough discussion
with other
RCOs that flushing
the blender following boration
was
no longer performed
by any of the
other
RCOs contacted,
nor recommended
during training.
Further, for the
RCO involved,
he stated that this activity was not normally performed.
This was confirmed by supervisory interviews.
Following discussions,
the Operations
Supervisor
immediately issued
a night order stressing
the
importance of operating
the plant,
and specifically the
CVCS, within
existing procedures.
The night order also stressed
that flushing the
blender following boration
was
no longer necessary.
The inspector considers this to be
an isolated incident.
Further,
no
observable
RCS power or temperature
changes
occurred.
Recent
observed
boration
and dilution evolutions
were all well performed in accordance
with procedures,
and with good oversight.
Further,
the operator
kept
positive control over this flushing evolution.
Technical Specification 6.8. I and
NRC Regulatory
Guide 1,33
(Rev.
2) section 3.n requires
written procedures
for the
CVCS to be followed.
The failure to follow
procedure
3-OP-46 during
a Unit 3
CVCS blender flushing evolution is
considered
a Violation.
The item is tracked
as
VIO 50-250,251/96-04-02,
Failure to Follow CVCS Operating
Procedure.
Operator
Response
to
a Unit 4 Hanual
Reactor
Trip
Operators initiated
a manual reactor trip of Unit 4 from approximately
17 percent reactor
power at approximately 6:00 p.m.
on April 9,
1996.
Just prior to the trip, operators
noted sluggish
main turbine governor
behavior
and ultimately
a rapid increase
in generator
load from 90 to
240
Hwe without operator
demand.
The
4A S/G level swelled to
71% caused
by further opening of the turbine control valves
and
steam flow was
noted to be greater
than feed flow on all three
S/Gs.
A manual reactor trip was initiated which caused
the main turbine to also trip.
Procedures
4-EOP-E-O,
Reactor Trip/SI and 4-EOP-ES-0. I, Reactor Trip
Recovery,
were appropriately entered.
RCS T,
reduced
from
approximately
552 degrees
F to 531 degrees
F Sue to the low decay heat
levels.
Minimum RCS pressurizer
level
reached
was approximately
12.4X.
The HSIVs were closed to prevent further cooldown
and decay heat
was
rejected
through the atmospheric
dumps,
Post trip response
was normal
with few exceptions.
Significant
among these
was shutdown
bank A,
control rod N-9 RPI not indicating
0 steps until approximately
two hours
after the trip.
The rod bottom light came in within the expected
time
frame
(see section
M2.1 for more details
on control rod N-9 testing).
The licensee attributed the governor sluggishness
to
a blocked (from
corrosion buildup) orifice within the governor impeller oil pressure
line.
The orifice was cleaned
and the governor refurbished.
The
maintenance
aspect of the Turbine control
system is further discussed
in
section Ml.5 of this report.
The inspector
responded
to the site
upon notification.
(b)(2)(ii) notification was
made
by the licensee
at 7:00 p.m.
on April
10,
1996.
The unit was restarted
on April 10,
1996 at approximately
5:00 p.m. after
an Event
Response
Team reviewed the event
and the onsite
safety committee
and plant management
authorized restart.
Further,
Unit
4
LER 96-01
was written and submitted.
The inspector monitored control
room activities following the reactor
trip as well as during startup.
The inspector
concluded that the
operators
appropriately
and conservatively
made
a decision to trip the
unit following plant response
to the increase
in generated
Mwe due
turbine governor problems.
The inspector also concluded that the
operator
performance
during startup
was cautious,
deliberate,
and well
supervised.
The inspector
reviewed
and closed
LER 96-01 for Unit 4.

The inspectors
concluded that this process
appeared
effective
and demonstrated
conservatism
in assuring that Unit 4 would be safely returned to service
following the refueling outage,
0
The inspectors
independently
assessed
Unit 4 restart

by
performing the following tasks:
reviewed selected
open
and closed work items including post-
maintenance
testing, deficiencies,
and commitments (e.g.,
condition reports,
PWOs,
PMAIs,
CTRAC items, etc.);
verified system lineups
and equipment availability by checking
TSAs,
system operating
procedure checklists,
the
TSA log,
clearances,
and the equipment out-of-service log;
toured the facility including the Unit 4 containment;
reviewed control
room instruments,
alarms,
and controls;
reviewed general
operating
procedure
implementation;
reviewed operator training and readiness;
reviewed outage
PC/H completion, testing,
and turnover (e,g,,
ITOP
and
SATS);
reviewed startup testing procedures
and readiness;
reviewed surveillance testing completion;
reviewed
and verified local leak rate testing
and containment
integrity;
and
reviewed
ISI and erosion/corrosion
inspections
and repairs.
The inspectors
concluded that Unit 4 was ready to support

Point on April 16,
1996.
The inspector verified that the meeting
was
conducted
in accordance
with Technical Specification 6.5.2,
NP-803
(Nuclear Policy - CNRB),
CNRB implementing procedures.
Generally,
the
CNRB meets monthly, rotating the location of the meeting
among the three
FPL sites (e.g.,
Turkey Point, St.
Lucie and Juno Beach).
Normally
representatives
from all three locations
are present
at each meeting.
The inspectors
also attended
several
PNSC meetings during the period.
Technical Specification
and procedure
requirements
were verified,
including meeting frequency,
quorum,
and review responsibilities.
The inspectors
reviewed the licensee's
recent
gA activities including
the quality trend report for the first quarter of 1996.
The inspectors
also met with QA supervisory
and management
personnel.
QA identified
negative
performance
trends
in several
areas.
This included root cause
analysis
improvements,
welding qualification record problems,
procedure
adherence
issues,
and
FHE concerns.
QA issued findings in their
periodic reports
and discussed
these
issues
with plant
and site

Unit 4 Outage
Maintenance Activities
For the general
maintenance
activities identified in section
Ml above,
the inspectors
observed
a portion of the in-process activities
and
verified compliance with applicable requirements.
For the work
activities observed,
the inspectors
found that detailed
procedures
were
in place
and were being followed,
Work activities were being performed
in accordance
with requirements
by knowledgeable
and qualified personnel
in
a professional
manner.
Flow Accelerated
Corrosion Activities
The
FAC program
was reviewed during
NRC Inspection
Report 50-250,251/96-
02.
This included the documentation of inspection of the
FAC program
and the planned
inspections for the Harch
1996 Unit 4 refueling outage.
During
FAC inspections for the Unit 4 outage,
the licensee identified
several
components
in the Hain Steam
(HS)
and Feedwater
(FW) Systems
that did not meet the minimum thickness
screening
requirements
specified
in the program.
The screening criteria is conservatively
set to ensure
that
a component will not degrade
below minimum wall thickness
before
the
end of the next cycle
and is based
on adding
a wear allowance for
one cycle to the minimum required wall thickness.
The wear rate is
determined
by actual
thickness
measurements
taken over
a given time
period (usually one operating
cycle), or by subtracting
an actual
thickness
measurement
from an
assumed
starting thickness'ny
components
found below the screening criteria require engineering
disposition.
The inspectors
reviewed the following 1996 Condition Reports
which
documented
resolution of HS and
FW components
found to be below minimum
thickness
screening criteria:
229,
230,
231,
301,
339,
and 355.
All of the
MS components
were determined
to be acceptable
for another
cycle of operation.
Eight
FW components
were replaced with upgraded
material
(Cr-Mo) and four were determined to be acceptable
(see section
H1.3 below for inspection of welding associated
with the replacements).
The replaced
components
were the expanders/reducers
and short pipe
sections
on either side of the "A" and "B"
FW Flow Control Valves.
The
FW components
found acceptable
for another cycle were the
same
components
on either side of the- "C"
FW Flow Control Valve.
Based
on
a
detailed
review of the engineering
analysis for disposition of the
above
12
components
and discussion of the evaluation
and disposition review
process,
the inspectors
determined that the dispositions
were
appropriate.
In addition to the above
FW piping,
one short section of
FW pipe in the
"B" feedwater line inside the containment
was replaced with Cr-Mo
material during the current outage.
All accessible
FW components
inside
the containment
have
now been
inspected.
None of the
FW piping inside
the containment
has
shown severe
FAC wall thinning.
In general,
the
thinning has
been in counterbore
areas
that started
out thinner than the
adjacent
piping.
The wear has
been general
rather than
a localized
corrosion attack.
Based
on the
above review, the inspectors
concluded that the licensee's
FAC program is working well and that the process for evaluation
and
disposition of inspection results is
a strength.
Pipe Welding
As noted in section
M1.2 above,
the licensee
replaced
a number of
sections of
FW piping during the Unit 4 outage.
These
replacements
required
making
10 pipe welds during the Spring
1996 Unit 4 outage.
In
addition,
due to
a leak in the
4A Residual
Heat
Removal
(RHR) Heat
Exchanger outlet nozzle to shell weld area
(reference
condition report
96-204),
the outlet nozzle
was
removed
and
a
new nozzle installed.
This
nozzle replacement
required cutting and rewelding
a section of the heat
exchanger outlet piping.
The inspectors
reviewed the welding and
Non destructive
examination
(NDE) records detailed
below for the
above described
pipe welds.
The
applicable
Code for this work was the
1989 Edition of Section
XI of the
ASME Boiler and Pressure
Vessel
which allows the
use
of the original construction
code,
or later codes,
for replacements.
The welding was performed in accordance
with welding procedure
specifications that meet the original construction
codes
as well
a later
editions of ASME Section III.
The applicable
Code Class is
ASME Class
2.
Since
Code
Case
N416.1
was used,
the applicable
NDE Code
was
Subsection
NC of the
1992 Edition of ASME Section III.
The following records for RHR welds

FW-2,
and
FW-3 on Drawing PTN-
C-96-028-001
were reviewed:

Welder qualification records for 10 welders
Material certification records for four heats of welding material
The inspectors
evaluated
the general
surface condition of all completed
except
FW-13R1
and
FW-14,
and verified that the surface generally
matched
what was
shown
on the
RT film.
As noted
above,
the applicable
Code for NDE was the
1992 Edition of ASME
Section III, Subsection
NC invoked by Code
Case
N416. 1.
During review
of the above
RT film, the inspectors
noted that the
RT technique
did not
fully meet this
Code relative to selection of type
and size of
penetrameter.
Subsection
NC has
a table for the selection of
penetrameters.
For all of the
above welds;
except the
RHR nozzle-to-
shell weld, the licensee
used the guidelines of ASME Section
V in lieu
the table in Subsection
NC.
After questioning
by the inspector, it was
determined that this question
had
been raised
by the
ASME Code
Authorized Nuclear Inspector
and resolved
by licensee
CR 96-460.
The
CR
identified that use of the penetrameter
selection table in Subsection
NC
was questionable
since it was originally issued for single wall exposure
RT and
has never
been
upgraded to cover double wall exposure
RT,
techniques
(the welds in question
used double wall exposures).
The
CR
further provided the argument that the
Code
Case only specified
use of
the
NDE methods
and acceptance
criteria of Subsection
NC and not the
technique.
The
CR also provided
ASME Code sanctioned
calculations
showing that the technique
used provided
RT sensitivities
equivalent to
that required
by Subsection
NC.
The inspector
concluded that the licensee
had
shown that the technique
used provided
RT sensitivities equivalent to that required
by Subsection
NC and
showed
the weld quality to be good.
However, for the welds in
question,
the penetrameter
selection specified
in Subsection
NC could
have
been
used to show equivalent sensitivity as that
shown
by the
technique
used,
precluding the need for technical justification for what
was done.
This omission to use
a technique that fully meets
Subsection
NC requirements
was considered
to be
a weakness
in the
program.
Except for the weakness
noted
above,
the inspector
concluded that
performance
associated, with the above safety-related
was good,
Personnel
were well qualified and work was well documented.
Visual
observations
and review of RT film indicated
good quality welds.

Unit 3 Hanual Trip During 4C Transformer
Testing
On Harch 27,
1996 at 5:16 p.m., operators
manually tripped the Unit 3
reactor
from IOOX power due to decreasing
S/G levels.
One minute
earlier,
the
3C
4KV bus
had unexpectedly
locked out and deenergized,
resulting in
a loss of one of two SGFPs
(38).
Haintenance
protection
and control personnel
were performing breaker
checks
on the
4C
transformer,
including the
3C bus alternate
feeder
(3AC01).
The
3ACOI
breaker
was in
a test position
and
was racked out of its cubicle,
resting
on the
3C bus floor.
The
3C bus is
a metal
enclosed,
non-safety
related
4KV switchgear.
The cycling of the
3ACOI breaker
caused
actuation of a
3C bus relay (3CBTX/FT), which resulted
in
a bus lockout
and tripping of feeder breaker
(3AC16) from the
3C transformer.
Control
room operators
entered

was subsequently
entered.
Safety
system
response
to the
trip was normal.
All control rods inserted
as indicated
by RPI and rod
bottom lights.
No issues
associated
with stuck or slow rod insertion
as
described
in
NRC Bulletin 96-01 occurred.
AFW auto started
(both trains
and all three
pumps),
and
no overspeed
problems occurred during startup
nor subsequent
shutdown evolutions.
No relief valves lifted,
temperature
and pressure
control
was normal,
and decay heat
was
removed
by the
and S/Gs.
The
NRC was notified pursuant to
(b)(2)(ii) due to the
and
ESF actuations.
The licensee
formed
an
ERT, initiated condition report No.96-481,
and
submitted
LER 96-06.
The licensee
determined root cause to be
mechanical
induced vibration caused
by the testing
(opening) of the
3AC01 breaker
(4C transformer feeder)
which resulted
in an inadvertent
actuation of relay 3XCBTX/FT and subsequent
3C transformer/bus
lockout
and
a loss of the
3B SGFP.
Loose steel floor plates
associated
with the
3C switchgear
and close proximity of the relay,
and intrusive Unit 4
testing were all causal
factors.
Corrective actions
included the following:
ERT review and report issued,
Post Trip Review performed,
PNSC
and plant management
review completed,
Verified (reproduced)
the root cause
scenario,
Repaired
3C and
4C switchgear floor plates,
Inspected

and
Verified primary and secondary
plant instrumentation availability.
The Unit restarted
on March 28,
and was placed
on line at 3:47 a.m.
on
Harch 29,
1996.
Full power was achieved
on March 30,
1996 (section
04.1).
The inspector
was onsite at the time of the trip and reported to the
control
room when the
PA announcement
was made.
Post trip conditions
were verified, including safety
system performance,
insertion,
and
EOP/ONOP implementation.
Unit 3 was verified to be in
Mode
3 and Unit 4 was in Mode
6 (cycle
16 refueling outage).
The
inspector
noted that both units were affected
by
a loss of the
3C and
4C
4KV buses.
However,
the
ONOPs were written for a Mode
1 (power)
condition
and did not specifically address
a loss of both buses.
The
inspector pointed this out to licensee
operations
management
personnel,
and
a commitment to address
this issue
was made.
The inspector
noted
very good
command
and control, communications,
and
EOP use,
The
inspector also toured the
3C bus
room and examined
conditions'he
inspectors
reviewed the
ERT and post trip review reports,
attended
the
PNSC meeting, verified corrective actions,
confirmed the root cause
analysis,
and reviewed
LER 96-06.
Discussions
with operators,
maintenance
personnel,
ERT members,
and management
were held.
The
inspectors
also reviewed the turbine runback circuitry which failed to
actuate
on the
3B SGFP trip.
Licensee
personnel
noted that the turbine
pressure
input was unexplainably isolated (e.g.,
PS-3-1604-1
was
closed).
The inspector verified that this circuit was not safety-
related.
However, the licensee
took extensive corrective actions,
including verification of all secondary
plant instrumentation prior to
restart.
The inspectors
also verified that appropriate
work controls were in
place for this
3C and
4C bus testing,
including
a
RWO, plant manager
approved
red sheet,
and appropriate
pre-job briefing.
The inspector
also reviewed
two previous events
where the
3C or 4C buses
were lost,
and
a resultant reactor trip occurred.
The inspectors verified that
corrective actions
taken in response
to the two previous events
were
completed,
and could not have prevented this recent Unit 3 manual trip.
The inspectors
also reviewed
UFSAR section
14'. 11 regarding
a loss of

Main Turbine Related
Issues
Causing the Unit 4 Manual Reactor Trip
The inspector
reviewed the root cause attributed to the Unit 4 reactor
trip that occurred
on April 9,
1996 that is also discussed
in section
04.2 of this report,
Following troubleshooting
on the main turbine
governor,
load limit device, auxiliary governor
as well
as associated
components,
the licensee
concluded that the event
was caused
by
corrosion products that fouled the impeller oil orifice.
This impeller
oil line transmits
a signal
corresponding
to turbine
speed
to the
governor bellows.
The clogged orifice caused
the governor to sense
decreased
speed
and caused
an increase
in the control oil pressure until
the load limit took control to stop the increase.
With the increase
in
control oil pressure,
the turbine control valves
opened
causing
an
increase
in generated
Hwe.
Further, with the control valves opening,
the
S/G levels swelled,
prompting the operators
to trip the reactor.
The licensee
believes that the corrosion products
were formed
as
a
result of water intrusion into the open governor bellows hole when the
governor
was
removed
and covered with a temporary cover during the
recent refueling outage.
Water had
been cleaned
from the bellows hole
but the orifice at the bottom of the block had not been
cleaned
and
inspected after the water intrusion.
As corrective action to prevent
recurrence,
the licensee
plans to strengthen
the Foreign Material
Exclusion program
as applicable to main turbine maintenance
as well as
revise turbine maintenance
procedures
to include appropriate
and
complete inspection
requirements
should contamination
be detected
when
the turbine controls
are
opened for maintenance.
The inspector
reviewed licensee
actions
associated
with this event,
including troubleshooting
associated
with the governor.
The inspector
concluded that the licensee
appropriately initiated actions to address
maintenance
concerns
that were brought to light as
a result of this
event.
Further
LER 96-01 (Unit 4) was reviewed
and closed.
Maintenance
and Material Condition of Facilities
and Equipment
Followup
The licensee
responded
to
a Unit 4 control rod
(N9) which indicated
approximately
16 steps after
a unit manual reactor trip on April 9,
1996
(section H1.5),
NRC Bulletin 96-01, action 4, required the licensee
to
assess
control rod performance
during all trips.
Further,
the bulletin
required the licensee to conduct tests
to measure
and evaluate
rod drop
times
and rod recoil,
After the trip, the control
room RPI for control rod
N9 (shutdown
bank
A, group 2) went from full out (230 steps)
to
16 steps.
The rod
positian then drifted to full-in position
and the rod bottom light
17
illuminated (setpoint of 20 steps).
Further,
the time from the opening
of the reactor trip breakers
to illumination of the rod bottom light was
about
1.75 seconds.
The licensee initiated troubleshooting
on the
and duplicated "stickiness" of the indicator at several
locations of the
needle travel.
Based
on these observations,
the
RPI was replaced.
Subsequently,
rod N-9 was tested
pursuant to procedure
4-PMI-028.3,
Hot Calibration,
CRDM Stepping Test,
and
Rod Drop Test.
Three tests
were performed during the midshift on April 10,
1996.
All three
resulted
in drop times of about
1.35 seconds
to dashpot
region entry
(e.g.,
24 inches)
and about
1.85 seconds
to full-in position.
(The
Technical Specification 3. 1.3.4 requirement
is
a drop time of less
than
2.4 seconds
to dashpot entry).
During day shift on April 10,
1996,
the rod was again tested
and results
were similar.
Further,
the replaced
RPI was also verified to be
properly functioning during rod stepping
and rod drop testing.
The inspector
reviewed the rod drop chart traces,
and independently
confirmed that drop times were 1.35 seconds
to
RCCA dashpot
entry and
that little or no recoil occurred.
The inspector also
examined
the
module during bench testing.
NRR also reviewed these results,
including
chart traces.
Based
on these
NRC reviews,
the inspector
concluded that
Unit 4 control rod N-9 exhibited proper performance
and that the
licensee
appropriately replaced
a faulty RPI.
The inspector
noted
good
test coordination
among maintenance,
operations,
and reactor engineering
personnel.
The inspector
also observed effective briefings,
conservative
operations,
and strong
teamwork being displayed.
M2.2
Heater Related
Issues
Following Unit 4 startup
from refueling, the high level annunciators
associated
with the
1A, 2A,
and
did not clear
as
expected.
The licensee,
following troubleshooting, initially postulated
that the
had
a tube to shell leak.
The
3A and
4A
heaters
were isolated following a power reduction to 90X.
Investigation of the
3A feedwater
heater did not reveal
a leak.
Upon
further investigation,
the licensee
determined that the
1A and
2A
feedwater three
way bypass
valve stem
had separated
from the disc such
that the valve had failed in the feedwater
bypass position.
With
condensate
through the
1A and
2A feedwater
heaters
bypassed
the unit is
operating inefficiently with a loss of approximately
10 Mwe.
Repair of
the bypass
valve would involve
a unit shutdown.
The licensee
reviewed
the effects
on the plant of long term operation with the
1A and
2A
heaters
bypassed.
Further, with the flow characteristics
different, the licensee
evaluated
the effects
on secondary
pipe erosion.
During the valving of the
3A and
4A heaters
following tube inspection,
a
portion of the extraction
steam piping to the feedwater heaters
experienced
a water
hammer that resulted
in a vent valve pipe being
severed.
The unit had to be reduced to
60'A power to effect repairs of
that line.
18
The inspectors
also reviewed applicable sections
in the
UFSAR (section
10.0)
and noted that besides
the system drawing, the
UFSAR did not
detail feedwater heater operations.
Nevertheless,
the inspector
questioned
the licensee if there were plans to address
the affects
on
the
UFSAR related to operation with the
1A and
2A feedwater
heaters
bypassed.
Based
on, inspector questions,
the licensee
plans to look into
the matter.
The inspector
concluded that licensee
appropriately reacted
to the Unit 4 feedwater heater related
issues
and abnormalities.
Maintenance
Procedures
and Documentation
Unit 4 Integrated
Safeguards
Testing
The licensee
performed Unit 4 procedures
4-OSP-203. 1, Train A Engineered
Safeguards
Integrated Test,
and 4-0SP-203.2,
Train
8 Engineered
Safeguards
Integrated
Test,
during the Unit 4 Cycle
16 refueling outage.
Technical specifications
required testing various engineered
safeguards
features
including SI
(LOCA) with and without
LOOP, containment
phase
A
and
B isolation,
main steam line isolation,
control
room ventilation isolation,
and containment ventilation
isolation.
On March 29,
1996, during pretest
preparations
for Train A, per
attachment
2 of procedure
4-OSP-203. 1,
a personnel
error occurred
resulting in an unplanned
ESF actuation.
An invalid SI signal
was
initiated when pressurizer
pressure
test potentiometers
were incorrectly
installed
on two channels
simultaneously.
This action resulted
in
unblocking of the low pressure
SI signal
on Unit 4, causing Unit 4 and
Unit 3
ESF equipment actuations
(e.g.,
HHSI pumps,
EDGs, cooling pumps,
etc.).
No injection occurred
on Unit 4 as it remained
in Mode 5.
Unit
3 was in Mode
1 at
100X power.
RHR decay heat
removal
on the
4B train
was unaffected
on Unit 4.
Operators
secured
the affected
equipment,
notified the inspector, initiated condition report
No.96-509,
and
made
a
10 CFR 50.72 notification.
LER 96-07 was also written and submitted.
Corrective actions
included stopping the test until
a root cause
analysis
and corrective actions
were completed,
individual counselling,
and procedure
enhancements.
Further,
the
I&C department
was briefed
on
the event.
The inspectors
reviewed the
ESF actuation
event
and observed
portions of
the Unit 4 safeguards
testing.
Based
on problems
noted with the last
Unit 4 test in November
1994,
as discussed
in
NRC Inspection
Report 50-
250,251/94-23,
the licensee
made several
enhancements.
These
included
operations
management
coverage,
a dedicated
team of personnel
to perform
the tests,
simulator checkout of the revised test procedure,
improved
test briefings,
and other noted items.
The inspector also noted that
positive control
and strong communications
were maintained during the
testing.
During A train testing,
a
4KY bus stationary switch failed
(see section
E1.2) which required retesting.
Notwithstanding the error
that occurred during the pre-test evolution, the inspectors
concluded
that testing
was professionally
performed with good procedure
compliance
and strong
teamwork.
Further,
a strong safety perspective
was
19
maintained for the operating unit (Unit 3).
LER 96-07 was reviewed,
determined
to be adequate,
and
was closed.
Maintenance
Organization
and Administration
Post Maintenance
Testing
The inspector
reviewed procedure
O-ADH-737, Post Maintenance
Testing
as
well as discussed
the process
related to post maintenance
testing with
emphasis
on the role of the maintenance
planner.
Further,
the inspector
also
assessed
a Speakout
review associated
with the post maintenance
tes'ting
process
that was conducted to ensure
compliance with existing
procedures.
The Speakout
review had also selected
a large
sample of
completed
PHTs to ascertain
compliance.
The Speakout
review did not
have
any adverse
findings.
However,
Speakout
made
a recommendation
with
regard to the maintenance
planner involvement in PMTs.
The
recommendation
involved documenting
the source of information upon which
the planner relies to sign-off that
a
PHT was completed.
This
documentation
of the source
on the completed
PHT attachment
to the work
package
would alleviate potential
concerns
regarding verification of
completion of PMTs.
The inspector
confirmed that the licensee
plans to adopt this
recommendation.
The inspectors
plan to continue to determine
licensee
process
and implementation of the post maintenance
program during future
inspections.
Further, for the recent inspections
performed,
the
inspectors
have noted
no significant abnormalities
in the implementation
of the post maintenance
test
program.

Inspection
Scope
(37551,
90712,
90713,
and 92700)
The inspectors verified that licensee
engineering
problems
and incidents
were properly reviewed
and
assessed
for root cause
determination
and
corrective actions.
They accomplish this by ensuring that the
licensee's
processes
included the identification, resolution,
and
prevention of problems
and the evaluation of the self-assessment

program.
The inspectors
reviewed selected
PC/Hs including the applicable safety
evaluation, in-field walkdowns, as-built drawings,
associated
procedure
changes
and training, modification testing,
and changes
to maintenance
programs.
The inspectors
also reviewed the reports

Findings
Conduct of Engineering
Unit 4 Startup
and Physics Testing
The inspectors
observed
portions of the Unit 4 initial criticality,
startup,
and physics testing evolutions (section
01. 1).
The licensee
performed procedures
0-0SP-040.6,
Initial Criticality After Refueling,
and 0-0SP-040.5
Nuclear Design Verification.
These tests verified that
nuclear design criteria
and related predictions
were satisfactory.
Specific tests
included critical boron concentrations,
control
rod
worths,
temperature
coefficients of reactivity,
and power distributions.
Technical Specifications
3/4. 1. 1.3, 3/4.2.2,
and 3/4.2.3 were also
verified.
The inspectors
reviewed the test results
and independently
confirmed
that acceptance
criteria were met.
The inspectors
noted very good test
coordination
between operations
and reactor engineering
personnel.
The
inspectors verified that these tests
were conducted
in accordance
with
procedure

and conducts
4KV Bus Stationary
Switch Failure
During performance of Integrated
Safeguards
testing of the
4A 4KV bus
(see section
M3. I), the licensee
determined that one of the bus clearing
relays failed to actuate.
The licensee
concluded
the failure to actuate
was caused
by breaker
4AA19 stationary switch failing to operate its
contacts
as required.
The
4AA19 breaker supplies
the motor for the
4A
ICW pump.
Upon disassembly
of the
4AA19 stationary switch, the licensee
determined
that one of the internal
cam followers had failed (cracked)
such that
its respective
contacts
were not closed.
This internal
cam follower is
manufactured
of "Lexan" (polycarbonate).
In 1976 the manufacturer
(GE)
replaced this material with a different type due to problems with
cracking of the "Lexan" material.
BWRs were provided with this generic
information.
Subsequently,
was also
issued.
The licensee
reviewed their data
base
and determined that this switch
was
used in the
4KV safety
buses
as follows:
3A
three switches
3B
-
two switches
4A
-
16 switches
4B
none
Inspection of several
of the installed accessible
stationary
switches
confirmed the cracking issue,
Condition report
No.96-523
was written
21
including an operability assessment.
This included
a failure effects
analysis.
The licensee
concluded that all four 4KV buses
were operable.
The basis for this conclusion
was:
isolated
random failures reported
by the manufacturer
and
by the
industry,
Turkey Point failure data limited to one occurrence,
Manufacturer's
assessment
that the switches
would function 45,000
cycles with existing cracks,
minimal stress
on the
cam followers and roller pins,
limited number of the affected switches currently in use,
random failure events
bounded
by single failure criteria,
plans to change
out affected switches at the next opportunity.
The inspector
reviewed the issue,
including the condition report.
Selected
switches
were inspected
and the inspector confirmed the failure
mechanism.
was reviewed,
and the issue
was
discussed
with engineering

personnel.
The inspector
concluded that the licensee
appropriately
addressed
and dispositioned
this switch issue
including the extent of the condition.

E2. 1
Cross-Tie of Safety Injection Cold Leg Accumulators
Based
upon
a review of a recent
10 CFR 50.72 notification made
by Indian
Point
2 involving cross-tie of safety injection cold leg accumulators,
Turkey Point performed
a review of current plant procedures
and practice
to determine applicability.
During this review, it was determined that
Turkey Point procedures
for transferring nitrogen or water through
'ommon
fill lines allowed the cross-tieing
safety injection
Further,
operators
were interviewed
and the practice of
simultaneously filling the accumulators
had
been
performed in the past.
Thus,
in the event of a loss of coolant accident requiring accumulators
during
an ongoing fill of two or more accumulators,
the accumulators
not
attached
to the severed
RCS cold leg had the potential for being
depressurized
via the cross-tied lines through the break.
This loss of
pressure
could prevent the core reflood capabilities of the
in the early stages
of response
to
a loss of coolant
accident.
The Turkey Point accident analysis
assumes
that the content of two
or 1750 cubic feet of water,
are utilized during core
reflood.
Consequently,
preliminary assessment
was that
the reflood analysis
had insufficient margin to accommodate
the
potential
pressure
loss in the accumulators
attached
to the intact
/~
22
system loops.
Thus the licensee
concluded that the
practice of cross tying multiple accumulators
during fill evolutions
was
considered
reportable
under
(2) (iii) (D),
an event or
condition that alone could have prevented
the fulfillment of the safety
function of the accumulators
to mitigate the consequences
of an
accident.
The licensee
performed
a
PSA analysis of the core
damage
frequency
increase
due to the cross-tie of accumulators.
A bounding time of 30
minutes
per
day was
assumed
in which all three accumulators
were
considered
out of service simultaneously.
No other risk significant
components
were considered
to be removed
from service.
Based
on these
conservative
assumptions,
the licensee
calculated
an increase of 4.2N in
the core
damage
core
damage
frequency.
The assumptions
did not take
credit for any operator actions.
As corrective action,
the licensee
updated
procedures
3/4-0P-064,
Safety
Injection Accumulators,
to allow only one fill valve open at
a time when
RCS pressure
is above
1000 psig.
This would preclude the cross-tie of
the accumulators.
Further,
operations
reviewed other applicable
systems
for cross-tie affects.
No other similar systems
were found.
The
licensee
submitted
LER 96-05 pursuant
to
(a) (2)(V)(D).
The
LER remains
open.
The inspector
concluded that the identification of this issue during the
review of events
at other plants is considered
a strength.
Cross-Tie of the
Two Safety
Buses
The inspector
reviewed Condition Report
number 96-373 dated
March 18,
1996, that
was originated
by an
NPS.
The issue
was associated
with
electrical configuration that momentarily cross-tied
the two independent
4KV buses
(4A and 4B), through the
480
VAC load centers.
During
a
refueling outage or other defueled period,
each unit's
4
KV buses
are
de-energized
(non-concurrently)
to allow for modifications or periodic
maintenance.
This de-energization
also effectively takes
the associated
EDG out-of-service,
While each
4
KV bus is de-energized,
the
480 volt
load centers
normally fed from that
bus are cross-connected
to the
opposite train 480 volt load center to allow equipment required to
maintain cold shutdown
and refueling modes to perform outage related
components
energized.
For example,
when the Unit 4 4A bus is not
energized,
the
4A 480 volt load center is fed from the
4B 480 Volt load
center.
The
4B 480 volt load center is energized
from the
4B 4KV bus.
To accommodate
a live transfer, i.e,, without de-energizing
the
4A load
center,
the cross tie is accomplished
before the
4A 4
KV bus is
deenergized.
Thus,
from the time that the
4A and
4B load centers
are
cross-tied until the
4A load center is disconnected
from the
4A 4
KV
bus,
the
4A and
4B 4
KV buses
are electrically tied.
The condition also
occurs during the cross-tie of the
4C and
4D 480 volt load centers
as
well as
on Unit 3.
Further,
the buses
are tied prior to returning the
configuration to accommodate
continuous
energization of the load center.
This cross-connecting
of the load centers
to the opposite trains
4
KV
23
bus is permitted
by Technical Specification 3.8.3.2 provided
a safety
evaluation
ia performed,
The breakers
associated
with the load centers
that are required to be
operated
are located in each unit's
480 volt load center
rooms
and are
operated
in accordance
with procedure
3 or 4-0P-006,
480 Volt Switchgear
System.
The duration during which the two 4 KV buses
are cross-tied
is
very short
(few seconds).
If a
LOOP were to occur during this
condition,
where the two 4
KV buses
are cross-tied,
the
4A and
4B
would attempt to energize their respective
buses electrically out of
phase,
potentially damaging
both the
EDGs.
As immediate corrective action,
the licensee
modified procedures
3 and
4-OP-006
such that it cautioned
the operator to complete the alignment
such that the interval
when the busses
are interconnected
would be
limited to 16.5 seconds.
16.5 seconds
corresponds
to the time required
for the
EDG startup
and complete
sequencing
of the first load block.
Further,
the licensee
plans to update Unit 3 and
4 safety evaluations
JPN-PTN-SEEJ-88-042
and JPN-PTN-SEEJ-89-085.
These safety evaluations
were performed to address
the cross-connection
of load centers
during
the
4
KV bus outage.
However,
the safety evaluation failed to recognize
and therefore consider the effect of cross-connecting
the
4 KV buses.
The failure of the safety evaluations
to consider fully the effects of
cross-connecting
the load centers
is considered
a Non-Cited Violation,
50-250,251/96-04-03,
Failure to Perform
an Adequate Safety Evaluation.
This meets
the criteria specified in section VII.B of the
NRC
The
NCV is closed.
The inspectors
also reviewed
UFSAR chapter
8,
and noted that section,
8. 1. 1.3 stated that "each of the four
EDG is connected
to a separate
power train".
This
UFSAR design basis
was not met momentarily for the
situation described
above.
Further,
the Technical Specifications
allow
this deviation during Node 5/6 operations.
The licensee
intends to
address
this issue
on
an
UFSAR revision.
The inspector
concluded that the questioning attitude exhibited
by the
NPS that led to the identification of the problem is
a strength.
Emergency
Containment
Cooler Valve Failure
On April 2,
1996,
the
4C
ECC outlet valve,
CV-4-2908, failed to open
during the air fail test portion of procedure
4-OSP-055. 1,
Emergency
Containment
Cooler Operability Test.
The
ECC outlet valve supplies
to the
ECC heat
exchangers
located in containment.
The
ECC outlet
valves
are normally closed
and
open
upon
an
ECC demand signal following
an SI.
The
ECC inlet valves
are normally maintained
in the open
position.
There
have
been other recent
problems with the
ECC valves
previously discussed
in
NRC Inspection
Report
Number 50-250,251/96-01,
Section 5.2.5.
The valve failure placed Unit 4 in a hold for entry into mode 4.
The
pilot lockup valve associated
with CV-4-2908 apparently did not shift as
24
designed
upon test conditions simulating loss of instrument air.
An
ERT
was formed to identify and correct the problem(s) that contributed to
the failure and Condition Report
number 96-535
was originated.
Fur'ther,
the licensee
concluded that the Unit 3
ECC outlet valves
and the other
Unit 4
ECC outlet valves
remained
based
on successful
completion of surveillance testing per procedures
3/4-OSP
055. 1.
The
pilot lockup valve acts
as
a pneumatic
switch
and changes
position when
the instrument air supply pressure
drops to
below 45 psig and
60 psig
on Unit 4 and Unit 3, respectively.
When the pilot lockup valve changes
position, the air accumulator
mounted
on the isolation valve actuator is
aligned to the actuator cylinder to open the valves.
The
ERT troubleshooting
and investigation
concluded that:
The pilot portion of the lockup valve bled
as required.
The accumulator
check valve operated
as required.
The spool
piece associated
with the pilot lockup valve did not
shift during field testing
as well
as
on bench,
thereby recreating
the failure.
The measured
force to shift the spool
piece toward the air fail
direction
was greater
than the spring force.
After initial
shifting of the spool pieces,
the measured
forces were acceptable,
repeatable
and equivalent to the forces
measured prior to
installation.
Thus,
the spring was at times incapable of
overcoming
spool
piece drag.
Further,
the
ERT also noted that the failed pilot lockup valve had
"Viton" "0" rings installed.
This change
from "Buna-N" to "Viton" "0"
rings
had
been
made earlier this year
on most pilot lockup valves
due to
age related degradation
issues
associated
with "Buna-N" "0" rings.
The
licensee
also postulated,
but could not definitively conclude,
that the
"Viton" "0" rings increased
the resistance
within the pilot lockup valve
such that the existing spring force was insufficient to overcome the
resistance.
Further,
the other pilot lockup valves that utilized
"Viton" "0" rings did not fail during testing.
Subsequent
testing
concluded that the "0" ring type did not affect lockup valve
performance.
Consequently,
the licensee
implemented
PC/M number 96-039 to increase
the pilot lockup valve spring stiffness
from approximately 5.5 lbs to
12
lbs.
This increased
spring stiffness is designed
to overcome
any drag
forces prohibiting spool
movement.
Further,
the licensee
also
has
decided to revert to the
"Buna-N" type "0" rings.
The
age degradation
related to the "Buna-N"
material will be addressed
through periodic
inspection.
Additionally, as
a temporary solution to enable Unit 4
startup,
the pilot lockup valve for CV-4-2908 was replaced with one
composed
of "Buna-N" "0" rings.
However, it maintained
the original
spring
as the
PC/M had not been
implemented.
Operability of CV-4-2908,
as well
as the other five
ECC outlet valves affecting both units,
was
maintained
through successfully
completion of procedures
3 and
4-OSP-
55.1
on
a daily basis.
No further failures
have since occurred.
r
25
As of the
end of the inspection report period, all
ECC pilot lockup
valves
had
been modified.
Testing
was changed
to every
3 days
and the
licensee
is pursuing another
change to do weekly testing.
The inspector
observed
portions of the troubleshooting
and investigation
as well as
reviewed
and discussed
the issue,
including the
PC/H, with the licensee.
The inspector
concluded that continued attention related to the
reliability of the
ECC is warranted.
The inspectors
intend to continue
to review this issue during future inspections.
No technical
specification violations were identified.

Review of Updated Final Safety Analysis Report
Commitments
A recent discovery of a licensee
operating their facility in
a manner
contrary to the
UFSAR description highlighted the
need for a special
focused
review that compares
plant practices,
procedures
and/or
parameters
to the
UFSAR descriptions.
While performing the inspections
discussed
in this report,
the inspectors
reviewed the applicable
portions of the
UFSAR that related to the areas
inspected.
The
inspectors verified that the
UFSAR wording was consistent
with the
observed
plant practices,
procedures
and/or parameters.
The following
UFSAR Sections
were reviewed:

Inspection
Scope
(71750,

The inspectors verified the licensee's
appropriate
implementation of the
physical security plan; radiological controls;
the fire protection
program;
the fitness-for-duty program;
the chemistry programs;
emergency
preparedness;
plant housekeeping/cleanliness
conditions;
and the
radiological effluent, waste treatment,
and environmental
monitoring
programs.
Inspection
Findings
Radiological Protection
and Chemistry
(RPKC) Controls
Unit 4 Refueling Outage
Performance
The inspector
reviewed the licensee's
radiological
performance
during
the Unit 4 Cycle
16 refueling outage.
Attributes reviewed
included
radiation dose,
personnel
contamination
events
(including skin dose
assessment),
spill prevention,
radwaste
accumulation,
and contamination
control (including contaminated floor space).
All goals established
before the outage
were met.
Further,
the inspector
noted that the goals
have
become
more aggressive
(e.g.,
lower value) over the past
few
refuelings outages.
The inspector
independently
assessed
HP performance
during the outage,
including maiztenance
and test activity coverage,
RWP review,
ALARA and
ARB activities,
containment
inspections,
and other in process
reviews.
The inspector
noted that the licensee
continued to use remote monitoring
of jobs
(see
NRC Inspection
Report
No. 50-250,251/96-02).
The inspector
also noted that the radiation
dose estimate
was
215
Rem,
and the actual
dose
was
158.5
Rem.
This represents
the best
ever radiation exposure
for Turkey Point during
a refueling outage.
Contaminated
Flashlight Event
On March 27,
1996,
an
IKC technician
noted
a purple painted flashlight
in the turbine building elevator vestibule,
outside the
RCA.
27
personnel
were immediately notified.
A survey confirmed fixed and loose
contamination
(1.0 k dpm).
A survey-of the area did not find any
contamination
spread.
The licensee initiated Condition Report
No.96-480
and
an investigation.
The licensee
could not conclusively determine
how the flashlight passed
through the
RCA control'oint.
However,
they believe it probably
bypassed
the normal controls through the auxiliary (turbine building)
control point.
Licensee corrective actions
included:
Temporarily closed
the auxiliary control point;
Posted
HP technicians
(part time)
and
a camera at auxiliary
control point to provide surveillance;
Surveyed all areas
outside of the
RCA for purple material
and
possible contamination.
None was found;
Informed all site personnel
of the event;
Briefed
HP personnel
on the event;
Mrote
a Nuclear Problem Report
No.96-480;
Plans to inventory and
number all purple material
by June 3,
1996;
Revised training to include this issue
and corrective actions;
and,
Modified HP routine surveillance
checks to include purple material
surveys.
The inspector
reviewed this event,
examined
the flashlight and survey
data,
reviewed the condition
and problem reports, verified corrective
actions,
and independently
inspected
the
RCA and
non-RCA for purple
material.
The inspector did not find any additional purple marked
material
outside the
RCA.
The inspector
concluded that this issue is
a
licensee identified violation.
The violation will not be subject to
enforcement
action
because
licensee corrective actions
were prompt
and
appropriate.
This meets
the criteria specified in Section VII.B of the
The item is tracked
as
NCV 50-250,251/96-04-04,
Contaminated
Flashlight
Found Outside the
RCA.
The
NCV is closed.

Conduct of Security
and Safeguards
Activities
Non-Credible
Bomb Threat
On April 15,
1996, at approximately
2:00 p.m.,
a former Turkey Point
security officer was involved in a motor vehicle accident
on U.S.
Route
1, approximately
30 miles from Turkey Point.
The Florida Highway Patrol
responded
and
upon search of the vehicle discovered
a device containing
an aerosol
can, wires,
and
a timing device.
The Metro-Dade
Bomb Squad
responded
when contacted
by the
FHP.
The device
was determined to be
a
non-explosive training aid which had previously been
used at Turkey
Point.
The individual when asked stated that "the device
was to test
his friends at Turkey Point".
The individual was previously employed
by
Security Bureau,
Inc.,
a contractor serving Turkey Point.
The
individual was not enroute to Turkey Point
on the day of the vehicle
accident.
The non-explosive training devise
was destroyed
by the
bomb squad.
This
event
was witnessed
by
a local
TV news crew.
The individual was
arrested
and later released.
Though the licensee
did not consider this to be
a credible threat,
the
licensee
conservatively reported this incident to the,NRC.
The
inspector discussed
the incident with the security supervisor
and
concluded that the licensee
actions
were appropriate.
Fitness
For Duty Event
On Hay 2,
1996, at 1:33 p.m., the licensee notified the
NRC per
10 CFR 26 that
a licensed operator
(RCO) tested positive for marijuana.
The
testing
was randomly performed
on April 29,
1996,
and the results
became
known at 11:20 a,m,
on Hay 2,
1996.
Condition Report
No.96-667
was
written.
The licensee
suspended
the
RCO's
access
and relieved the individual of
licensed duties.
The licensee
confirmed
no on-site
usage
and reviewed
the individual's work activity history.
No abnormalities
were
identified.
The inspector
reviewed the condition report,
the
NRC notification work
sheet,
and other pertinent documentation.
Discussions
were held with
plant and operations
management,
and with security
and
FFD personnel.
The inspector
concluded that licensee
appropriately reacted
to this
issue.
The inspector
independently
reviewed the
RCO's work history and
did not identify any problems,
The inspector
noted that management
reacted
aggressively
and promptly to this issue,
including meetings with
all licensed
operators.
