Conduct of Operations
Loss of the
3C Normal Containment
Cooler
71707
On May 21,
1997, the Unit 3 3C
NCC was stopped
by operators
due to
observed
low motor
amps.
Operators
responded to this loss of one of the
four non-safety related
NCCs by checking containment air temperatures
and monitoring the operating
equipment in containment.
The overall air
temperature
and the reactor
coolant
pump
(RCP) motor stator temperatures
increased
a few degrees;
however, the increases
were well below alarm
and required action setpoints.
Off-Normal Operating
Procedure
(ONOP)
and Alarm Response
Procedure
(ARP) guidance were also reviewed,
but
implementation
was not required.
Maintenance
personnel
made
a contain-
ment entry and assessed
the
3C
NCC damage to be
a failed fan bearing.
Condition Report
(CR) No.97-887
and work orders
were written to address
repairs,
correction actions,
and causes.
Numerous containment entries
were
made to effect repairs
and the
3C
NCC was retested
and declared
on May 29.
1997.
The inspector
reviewed logs, the
CR, the work orders,
technical specifi-
cations
(TS) for containment temperature limits,
RCP parameters,
ONOPs,
and ARPs.
The inspector also reviewed the repair plan coordinated
by
outage
management;
the health physics
(HP) aspects
including dose
estimates;
personnel
safety assessments
due to the high temperature
envi ronment in the containment;
and, overall repai rs and post-mainte-
nance testing.
The inspector
noted that the training department
assessed
the effect. of a loss of .an additional
NCC'.
This-information
,was obtained
by, reviewing simulator..performance
and this was then.fed
back to the plant.
In addition, the licensee
assured that the* simulator
response,was
consistent with the plant.
Theins'pector
concluded that the licensee's
response
(including opera-
tions, maintenance,
and plant support 'groups) to the loss of the '3C NCC.
was noteworthy.
Non-licensed
0 erator
Tours
Ins ection Sco e
71707
The inspector
accompanied
selected
non-licensed
operators
(NLO) on their
daily tours inside the auxiliary building.
Observations
and Findin s
The operators
attended
the morning briefing in the control
room prior,to
starting the auxiliary building tour.
There was
a good questioning
attitude by the
NLOs during the briefings,
and good interaction between
the
NLOs and the licensed operators.
Specifically the inspector
noted
that on two different occasions
the operators
would continue to question
the reactor control operators
(RCOs)
on issues that were not clear to
them.
The discussions
would continue until the
NLOs obtained satisfac-
tory answers to thei r questions.
The tours started after the morning briefing.
During the tours, the
inspector
observed that the operators
were very familiar with the
equipment
and with the requirements
of the tours.
The operators
recorded all the data
on electronic data loggers,
i .e.,
no hard copy
data sheets
were used.
The operators
showed
a good safety perspective
during the tours.
For example,
the inspector observed that anytime the
operators
were not clear
on
a parameter
or had any questions
regarding
the equipment.
they would call the control
room for di rection.
Also.
on
one of the tours, the NLO's dosimeter
alarmed.
He quickly called the
shift supervisor to inform him of the alarm and to obtain di rection.
It
was later determined that the
NLO had mistakenly logged into the wrong
RMP.
This was
a corrected
on the spot by the
HPSS.
The inspector noted however, that there
was
a lack of questioning
attitude for housekeeping
items.
For example.
the inspector
noted
mops
on the floor, ladders,
tools,
and
some contamination clothing had not
been properly stored or put away.
The NLOs indicated that most of these
items
had previously been identified and reported,
but they did not know
the status of the items because
there
was minimal feedback to -the
on housekeeping
items.
Conclusions
There was good interaction
between the
NLOs and the control
room
personnel
including the
RCOs, during the control
room briefings.
The
NLOs were 'very knowledgeable with the equipment,and. the requi rements of
the. tours,
and showed
a good safety prospective..
There was
a .lack of
questioning attitude
on housekeeping
items. that had previously .been
reported.

02.1
Plant Affects From Adverse Weather
93702
and
71707
During the period June 7-11.
1997, the South Florida area
experienced
numerous
storms with periods of heavy rains. wind. and local flooding.
This weather
caused
room and equipment water ingress, electrical
grounds.
and equipment failures.
The most significant issues
included
a
motor phase-to-phase
ground fault on the 4A2 circulating water
pump and
a loss of the Unit 4 auxiliary transformer cooling equipment.
Operators
responded to these
problems
and entered the appropriate
ARPs and
ONOPs.
Units 3 and
4 remained at full power.
However, the loss of auxiliary
transformer
caused
operators to transfer electrical
loads to the Unit 4
startup transformer
(TS and safety related
power supply).
The licensee
assembled
an engineering
team to address
the water
intrusion issues.
A mechanical joint leak associated
with a conduit was
identified for the Unit 4 auxiliary transformer.
This leak shorted the
starting contactors for the oil pumps
and cooling fans.
Repairs
were
made
and the auxiliary transformer
was returned to service after
a 24-
hour outage.
The observed
room leaks were documented
and walked down,
and causes
were addressed.
Corrective actions were immediately taken,
with longer term actions planned.
Past actions
have been partially
successful
in reducing'ut not eliminating water intrusion into
equipment
rooms.
The inspector
observed
licensee actions
from the control
room and in the
field.
The inspector
noted that several
CRs
(Nos.97-964,
965,
972,
975,
and 977)
and
a problem status
summary
had been written.
Operator
response to this adverse weather,
and procedure
and TS compliance were
very good.
Engineering
involvement was also very good.
However,
additional licensee attention is warranted in this area.

Based
on risk importance,
the inspector
performed
a walkdown of the
common auxiliary building ventilation
system.
Observations
and Findin s
This system. is non-vital
and is described
in the Updated Final Safety
. Analysis Report
(UFSAR) sect'ion 9.8, plant drawings. 'system description,
and the Turkey Point. Probablistic Safety Assessment
(PSA).

The Turkey Point units share
two supply and two ..
e'xhaust fans...
02.2
02.3
The inspector walked down the system with the system engineer,
discussed
the operation with operators,
and reviewed Maintenance
Rule
applicability.
The redundant
fans are powered from Unit 3 and
4 vital
buses.
However, the fans
do not receive auto start signals.
If a
design basis accident with a loss of off-site power occurs
on one unit
and the opposite unit powered
fans are running. the auxiliary building
ventilation
system
remains in service.
However, if the accident unit's
powered fans are running, auxiliary building ventilation will be
momentarily lost until power is restored to the vital buses
and
operators
manually start the fans.
The inspector noted that emergency
operating
procedure
(EOP) guidance to restart the lost fans
was non-
specific.
The licensee
had previously recognized this and made
changes to specifically include steps to positively restore the fans.
This was in response to a training department
feedback
request.
The inspector questioned
the systems'esign
basis including UFSAR
~
PRA/PSA,
and Maintenance
Rule descriptions.
There is no design basis
document for this system.
The licensee
was able to assemble
appropriate
design basis
documentation.
The inspector also observed
system operation in the control
room, in the
plant,
and in the control
room simulator.
Training, operations'nd
engineering
personnel
appeared to be knowledgeable.
Further. the
inspector verified that Maintenance
Rule performance criteria were being
met.
Conclusions
The inspector concluded that the auxiliary building ventilation
system
was appropriately operated,
aligned,
and maintained.
EOP changes
were
~
~
roactively identified and made.
System engineering

surveillance verified the system flow path
and power avai labi.lity to the
required
components
at the corresponding
operating
mode:.
At the time of
~
02.4
the surveillance, both'nits were at
100K power.
The inspector
reviewed
the piping and instrument drawings
(P8 ID) for the
RHR system
and
verified that the surveillance
procedure
was consistent with the P8ID
flow path
and component electrical
requi rements.
The inspector verified
the correct
RHR valve positions
and electrical
requirements
in the
control
room panels.
Additionally, the inspector walked down the Unit 4
RHR system with the
system engineer
and observed the system engineer
perform the monthly
surveillance.
The inspector noted that two motor operated
valves,
(MOVs)
MOV 4-861B and
MOV 4-752B,
had traces of boron by the stem and
bonnet area.
The system engineer
noted that theses
valves
had already
been tagged with a
PWO for maintenance
work to be performed at the
upcoming outage.
The system engineer
provided significant detail
regarding the system flow path, operation,
history of the
RHR system,
and construction
and operation of the major components
in the system.
The inspector
noted the system engineer's
knowledge of the
RHR system to
be
a strength.
The inspector verified that the surveillance
schedule
for this test
was met and also reviewed the completed surveillance
packages
for the last six months
and verified proper licensee
reviews
and approvals.
Conclusions
At the completion of the surveillance,
the inspector concluded that both
units'HR systems,
were correctly aligned for standby operation.
The
systems
engineer's
knowledge of the
RHR system
was
a strength.
Control
Room Annunciator Status
71707
Numerous times during the inspection period. the inspectors
observed
that no control
room annunciators
were in an alarmed condition.
This
"blackboard" condition was noted
on different days
and shifts during the
inspection period.
The licensee tracks these off-normal (lit)
in the daily plan-of-the-day
(POD) report.
Operations
. personnel
report at the morning
POD meeting
as to the number of lit
and their status for resolution.
The inspector noted excellent support for operations
by both maintenance
and engineering in resolving lit (alarmed)
issues.
Achieving and maintaining
a control
room "blackboard" condition for both
units demonstrated
strong operational
performance.

training department relative to simulator training for
operators,
and simulator
use
and consistency for observed plant p'roblems
and transients.
This included the following activities:

Unit 4 automatic trip on April 23,
1997,
(Reference
NRC Inspection
Report
Nos. 50-250,251/97-04
section 04.1),
Auxiliary Building Ventilation response
(section 02.1),
Loss of the
3C
NCC (section Ol.l), and
Routine licensed operator
simulator refresher training.
In addition
~ the inspector
reviewed
a new training device developed to
reinforce the self-checking practices of Stop-Think-Act-Review (STAR).
A "STAR Simulator" was developed
in-house with guidance
from the
industry.
This simulator replicates
a control panel with switches,
controls,
and indications.
The simulator hardware is used in conjunc-
tion, with an "operating procedure" to test
an individuals self-checking
and therefore
STAR efficiency.
Since this training device is new, its
overall impact has not been yet assessed.
However, this device appeared
to be
a very good training aid.
In conclusions
the operations training department
was proactive
and very
responsive
in assisting plant operations,
and provided excellent support
for operations.
In addition,
assurance
of simulator quality and
consistency with the plant were noted.

71707
On June 3,
1997, during the 7:15 a.m.
morning management
meeting,
the
inspector noted that the Plant
Manage
and his three direct reports
(Operations,
Maintenance,
and Work Control Managers)
and the Services
Manager were all absent.
The Operations
Supervisor
was present
providing management
coverage.
In addition, the Site Vice President
was
onsite.
The inspector
reviewed licensee
procedures
and
NRC requirements
relative
to management
staffing and availability.
TS 6. 1. 1 requires that the
Plant Manager designate
in writing the lines of succession
in his
absence.
The inspector verified that this was done.
The lines of
succession
were the Operations
Manager,
the Services
Manager,
and the
Operations
Supervisor.
The inspector also verified that the Emergency
P'lan staffing requi rements
were met.
The inspector also discussed this
issue with the Site Vice'President:
FPL policy- requi res either the Site
. Vice President
or the Plant"Manager
be available (onsite).
The
.
. inspector
was also. informed that* bo'th the, Plant and Maintenance
Managers
were .attending
a local industry conference
and .were available within
about
60 minutes..
The inspector concluded
that"management

A was the operable
and
pump 3A was being tested.
The procedure
required that the two
ICW headers
be separated
from each
other prior to testing any of the three
ICW pumps.
Header separation
had been accomplished
by manipulating the following valves:
closing valve 3-50-307
and opening valve 3-50-309 located at the
intake canal
on the
ICW pump discharge
closing valve POV-3-4883 (closed
from the control
room);
and
closing valve 3-50-350
and opening valve 3-50-340 located in the
CCW heat exchanger
room on the
ICW to the
CCW heat
exchanger
ICW Pumps
3A and
3B were lined up to the operable
A.
Pump 3A was
operating
and
pump 3B was off but was operable.
Additionally,
ICW flow
was going through the
3A and
3B
CCW heat exchangers
from header
A.
Although header

pump
3C was operating
(on header
B) and there
was
ICW flow from header
B going to the Turbine

and to the
3C
CCW heat exchanger.
The test
was being performed by two people.
One senior nuclear plant
operator
(SNPO)
was at the
CCW heat exchanger
room and the watch
engineer
was at the intake canal.
There was also
a senior
reactor
operator
(SRO) trainee
who was observing the test.
The trainee arrived
after the test
had been started
and was at the intake canal with the
watch engineer
.
Communication
among the
SNPO, the watch engineer,
and
with the control
room was via walkie talkie.

logs show that there
was approximately 3,500

a short period (less than
5 minutes).
Having
realized there
was low flow through the header

temperature limit.
Additionally, the licensee
refer red to two safety evaluations that had
been performed
on this system to confirm their operability assessment.
The licensee
concluded the reason for having obtained the low flow
condition was because
the IST procedure did not provide sufficient
detai 1 during the iterative throttling process
and allowed for misinter-
pretations of the requirements.
In addition, there
had been
miscommuni-
cation during the throttling process
which led to the wrong valve being
throttled.
Significant changes to the procedure
(Revision dated 6/19/97)
and other
.
improvements
included the following:
Explicitly describing the throttling process
requi rements.
Specifically, step 7.1.26 was described in more detail,
and
additional
steps
were added to exclude having to interpret the

one
SRO and three operators to perform the
surveillance.
Two operators
are stationed at the

The inspector attended
the pre-job briefing for the subsequent
ICW 3B

and observed the surveillance
being performed.
This
surveillance
was performed using the
new procedure
and guidelines.
Overall the inspector
found that the surveillance
was well performed.
The inspector
noted that the system engineer
was at the briefing and
observed the surveillance
and was available
for questions
throughout the
test.
The pre-job briefing was very thorough.
Marked up
P8 IDs were
reviewed
and the
SRO went over everyone's
part of the surveillance.
Changes
in the procedure,
system alignments
and implications to plant
operations
were discussed.
Communication practices,
self'-checking
(STAR), and personnel
safety were also reviewed.
During the IST, there
were two operators
at the
CCW room and one operator at the intake.
Communications with the operators
and with the control
room was good,
and the roving SRO continuously verified activities in the
CCW heat
exchanger
room and at the intake canal.
However, the inspector
noted
that during step 7.2.21 'he operators
at the
CCW heat exchanger
room
did not unlock valve 3-50-370.
Step 7.2. 21 requi red unlocking valves 3-
50-380
and 3-50-370 in preparation for the throttling process to obtain
the required flow through the
3B pump.
The inspector
asked the opera-
tors why they had not unlocked the 3-50-370 valve.
The operators
replied that .ICW flow through the 3B heat exchanger
was sufficient and
they believed the valve was not going to have to be throttled.
Although
through the completion of the test valve 3-50-370 was not throttled, the
inspector
noted that the roving SRO was not informed that the valve was
never unlocked until after the throttling process
had been completed.
The licensee
corrected this minor issue on-the-spot
and is considering

no. 4-0SP-068.2.
Observations
and findin s
The inspector
noted that in calculating the differential pressure
across
the pump, the procedure
used the static suction pressure
instead of the
dynamic suction pressure,
i.e.. the static suction pressure
was
subtracted
from the dynamic discharge
pressure.
Further,
during the
testing the inspector
observed that the suction pressure
increased
when
the
pump was operating.
This increase
in suction pressure
was observed
on both the 4A and 48 containment
spray
pumps.
These observations
were later discussed
with the system engineer.
He
explained that
a number of years
back the procedure
had been
changed.
The system engineer
noted that the suction pressure
tap was in a very
turbulent, area
between
elbows.
The reason for the procedure
change
was
because
engineering did not believe that the increase in pressure
on the
suction side during pump operation
was
a correct reading,
and
consequently
chose not to use it in calculating the
pump differential
pressure.
The inspector
requested
to see the documentation
describing
the procedure
change
and any engineering analysis/testing
that was used
to support the change.
The licensee is gathering the information.
The
inspector intends to review this issue in the next inspection report.
The inspector noted during the vibration readings that the position
labels for the accelerometer
were not installed in the 4A containment
spray
pump.
This was later discussed
with the IST coordinator
and he
indicated that the
pump had been refurbished
and that they were planning
on putting the position labels
on the pump.
The inspector
verified the measuring
& test equipment
(M&TE) calibration
data
on the instruments
used for this surveillance.
However, the
inspector
noted that the accelerometers
.did not have any calibration
data.
In later discussions
with the
M&TE supervisor,
the licensee
indicated that the accelerometers
were not calibrated but they were
checked for hard failures per the vendors
recommendations.

personnel
stated that the oil usage
was similar.
The inspector also reviewed the cur rent status of the 48 RCP.
The 48
RCP has
had an historical oil level alarm which requires
operator

and enhanced
monitoring.
The licensee
determined that this oil
level alarm was due to a design deficiency.

Ouring the period, operators
noted minor pump casing leaks
on the 4A and
38 HHSI pumps.
The licensee quantified these
leaks by running each
pump
on full flow recirculation.
The leakage
was calculated to be 330 cubic
centimeters
per hour (cc/hr).
The licensee verified that this was
acceptable
per pump vendor requirements,
and the leakage
was less than
the total
as stated in the
UFSAR Table 6.2-12.
Licensee corrective
actions
included minimizing pump use for cold leg accumulator fills,
issuing
a problem status

performing daily leakage monitoring,
and
developing
an action plan to perform repairs.
On June 5 1997, the licensee identified that the 4A HHSI had two

On March 4
~ 1997, control

The fire was in the 4A
control rod drive motor-generator
(HG) set.
The inspectors
reviewed
Condition Report
No. 97-0286
and attended
the Plant Nuclear Safety
Committee
on this subject.
The inspectors
evaluated
engineering's
support for the other plant organizations for determining the root
causes
and
recommending corrective actions.
The event
was reviewed in
NRC Inspection
Report
No. 50-250,251/97-03.
Observations
and Findin s
The
CR documented
the evaluation of the following three aspects
of the
subject event:
(1) the fire and fire response;
(2) effects of the dry
chemical
from the fire extinguisher
on the
HG set
and surrounding
equipment;
and,
(3) the root cause for the bearing failure on the
HG
set.
During this review, the inspectors
concentrated
on the third
aspect
(the root cause of the bearing failure).
The bearing failed prematurely after
11 months of service.
These
bearings
normally run 36 months without,failure before replacement.
Several possibilities
were considered for the root cause of the bearing
fai lure.
One was the possibility of an increase
in vibration for the
Unit 4
HG set
as
a result of stopping the Unit 3
HG sets.
Vibrational
measurements
eliminated this as
a potential root cause.
A second potential root .caUs'e,
an insufficient lubrication problem,
was
considered. 'ecords
show'hat the beating
had been lubricated in the
same
manner. as were all- of. the
MG set bearings
si.nce
1983.
The licensee
used less lubri'cation than the vendor
recommended with apparent
success
since
no fai lure ha'd occurred'in this. type of bearing in the last
10
years.
Approximately 1.5"cubic inches of grease
was found in the
inboard bearing cavity even after the fire.
The licensee'ha's'ecided.to.
increase. the amount of grease .injected in the bearing during preventive
21
maintenance activities.
The licensee realized
and industry experience
showed that the bearing
can fail from too much grease,
as well as too
little.
A third potential root cause
was
a materials or fabrication problem.
Vibration analysis
taken within a month of the bearing failure did not
indicate any degradation.
The inspectors
reviewed the metallurgical
analysis
and discussed
the results during
a tour of the
Metallurgical Laboratory facilities.
A review of the information in the analysis
showed the material
used
was
alloy 52100 which was
a correct material selection.
The thickness
and
color of the oxide on the fracture face of a crack across
the inner ring
of the bearing indicated that the temperature of the part had exceeded
650 degrees
Fahrenheit
(F).
Normally these
bearings
are not operated
above
300 degrees
F and lubrication usually breaks
down between
400 to
450 degrees
F.
This information indicated that the final fai lure of the
bearing
was caused
by lack or fai lure of lubrication.
In addition, the
extreme friction between the unlubricated metal parts generated
enough
heat to temper
(soften) the normally hardened
steel structure.
No
abnormal fracture face characteristics
nor abnormal structures
or
chemistry were noted.
c.
Conclusions
'he
exact root cause of the failure could not be determined.
However,
the inspector
independently
reviewed the professional
approach
for
evaluating bearing fai lures in accordance
with Volume ll American
Society of Materials
(ASM) Handbook,
Failure Analysis and Prevention,
Section,
Failure of Element-Roller
Bearings)
and concluded that the
licensee
had performed
a thorough
and proper root cause analysis.
Also,
the inspectors identified a positive finding that the licensee
had
a
good Metallurgical L'aboratory with excellent equipment
and that Turkey
Point was proactive in requesting
the laboratory's
services
for failed
components
or parts.

The inspectors
reviewed Condition Report
No. 97-0070,
which was
origina11y written to retube the 38
CCW heat exchanger.
An operability
determination
was
made for all of the Unit 3
CCW heat exchangers
because
of the presence
of foreign material
found in 3B.
The majority of the
material
was from a stainless
steel wire mesh strainer
placed in the
line before
1972 (pre star tup).
In the 3A heat
exchanger
the foreign
material
appeared to be similar.
No unusual
wear or failure of the
tubing could be attributed to the foreign material
and thus
no
operability problems existed.
The inspectors
had no problems with the
logic used for the operability evaluation.
The inspectors
observed
some of the detubing
and retubing operations,
cutting an opening in the shell of the heat exchanger
vessel
to remove
the foreign material,
and
some of the welding to replace the opening in
the shell.
Discussions
were held with the systems
engineering at
various times during the project.
Conclusions
The inspectors
observed that the
r etubing operation
was properly
performed.
Also, the inspectors
observed
strong engineering
support for
maintenance
and operations
during this project with around the clock
shift coverage
by engineering
personnel.
This was another
example of the excellent support provided by
engineering for the operations

Although the probability that any initiating event will lead to core

NRC and the nuclear utilities do not consider the
probability to be negligible.
Each of the uti.l-ities has committed to
establishing
a severe
accident
management
program
and to training the
appropriate
personnel
on this program.
The inspectors
monitored part of
this training during this inspection period.
Observations
and Findin s
The inspector attended
the licensee's
training for site engineers
in the
use of Severe Accident Hanagement
Guidance
(SANG) developed
by the
Owners Group
(WOG) and,individually modified,for each
nuclear plant:
This guidance
was for managing .in-plant aspects
of a
severe accident.
In the Emergency 'Operating
Procedures
(EOPs).
the
emphasis
was
on preventing core damage.
~ In the
SANG, the presumption..
was that core
damage
had already occurred.
Therefore;
when the
transition from the
EOPs to the
SANG was
made, priorities shift from
reventing core
damage to preserving the containment fission product
arrier and arresting'the
progression of core damage'.
24
The Emergency
Plan (E-Plan)
and Emergency
Plan Implementing Procedures
(EPIP) provided guidance for managing the off-site aspect of both within
the design basis
accidents
(covered
by the
EOPs)
and severe
accidents
(to be covered
by the new SANG).
Thus the
SANG filled a void that
previously existed
between the
and the E-Plan.
The
WOG consensus
was that the engineering
approach
was the best suited
approach to the evaluation
and decision
making process
required for
severe
accident
management.
Therefore the
SAMG was for the evaluators,
i.e.,
a member of the Technical
Support Center
(TSC) task with certain
diagnostic
and evaluation duties.
A small part (two Control
Room
guidelines) of the
SANG was for, the implementors, i.e., for the Control
Room operators.
The
SANGs were guidelines
and not step
by step procedures.
Actions to
manage
a severe
accident tend to exert both positive and negative
impacts simultaneously.
For decision making on whether to take
a
particular action, the
SANG user
must evaluate the potential positive
and negative aspects
based
on existing
(and sometimes
on projected)
plant conditions.
The training covered
some of the following:

The lamp was
returned to the

The inspectors
reviewed the corrective actions for the CRs. Section
7,
of the licensee's
CRs concerned
the analysis,
corrective actions,
generic implications, disposition details.
and work instructions.
The
inspectors
found that
CRs 654,
659,
664.
and 667 each referred to an
attachment
which stated there were several
instances
of the loss of
control or misidentification of radioactive material
and "Purple" tools
during the refueling outage.
The attachment
also addressed
eight
corrective actions which were identical for each
CR.
The licensee
had
addressed
the procedure violations
as
a program problem and not isolated
events
and that was the reason the corrective actions were the same.
The site Quality Assurance
(QA) staff also noted that several
examples
of improper control of radioactive material or contaminated tools had
been identified and documented
in CRs during the first quarter of 1997,.
The
QA staff identified the problem as
an area for further improvement
in a Quality Assurance Quarterly Report,
dated
May 21,
1997.
The
'department initiated
CR 97-760
on April 17,
1997, to cause'-a
review of
the sites contamination control problems.
The
QA department
recommended
that the
HP staff perform an evaluation of previous corrective actions
to the
NCVs to determine
why they were not effective.
At the time of
the inspection the licensee
was performing
a root cause
analysis to be
completed
by June
15,
1997.
The
QA report also identified another concern.
In the fourth quarter of
1996 and the first quarter of-1997 there
had been three
and nine
anonymous
CRs written in the.two quarters'espectively.
'Two of the..
'hree
in the 'fourth quarter were in the
HP, area
and five. of the nine in
the first quarter were in the
HP area.
The
QA report .stated the
anonymous
repoi ts indicated
a reluctance to .report problems to
supervision.
HP manag'ement
reported. that management
encouraged
the
reporting o'f problems in the
CR program.
The previous radia'tion
protection program review made by 'NRC in March 1997., 'documented
low
morale in. the. HP department.
Conclusion
29
R1.2
The licensee's
methods for controlling contaminated
and potentially
contaminated
items exiting the
RCA had not been effective in 1997.
There also appeared to be reluctance to report procedure violations and
other problems to HP supervision.
These
problems were reported through
the
CR process.
Release of Radioactive Contaminated
Paintin
E ui ment To Unrestricted
Areas
Ins ection Sco
e
83750
This area
was revi ewed to evaluate the ci rcumstances
concerning the
release of contaminated
equipment
from the Turkey Point site.
Observations
and Findin s
Background
The licensee utilized special painting equipment to paint the surfaces
of the reactor cavity walls during refueling outages.
The paint sealed
the contamination
on the walls to minimize the spread of radioactive
materials in the work ar ea.
The paint also helped decontaminate
the
walls when it was later stripped from the walls.
The painting equipment
was
owned by Power Systems
Energy Services,
Inc (PSESI).
The vendor
needed the equipment for
a simi lar job at the Braidwood nuclear station
in Illinois.
On March 25,
1997. licensee
personnel
logged the release of the painting
equipment
on licensee
form "RCA Release
Log."
The equipment listed
included two PSESI paint pumps with hoses
and fittings.
The equipment
was shipped to the vendors'acilities
in Altamonte
Springs.
From there the equipment
was taken to a paint supply
company for maintenance.
The maintena'nce
was performed
by Lee Patterson
Company in Orlando, Florida.
The equipment
was shipped
from the
maintenance
shop to the Braidwood nuclear station.
Neither
PSESI or Lee
Patterson
possessed
a radioactive materials
license.
Braidwood personnel
surveyed the equipment prior to it's use at thei r
facility on April 30,
1997,
and found fixed contamination
up to 5,000
dpm and .smearable
contamination
up to 3,000 dpm/100 cm'.
The licensee
was notified of the contamination
problem on May 1,
1997.
,. The licensee. notified the State of Florida Department of Health,.Bureau
of Radiation Control
(BRC), the
NRC resident inspectors.
and made
a
report in accordance
with 10 CFR 50.72(b)(2)(vi) on May 1,
1997.
Representatives
from the Florida
BRC surveyed the
PSESI
and
Lee Paterson ..
facilities where the equipment
had been stored
and worked on.
The
also surveyed the vehicle used to carry the equipment to maintenance
30
facility.
The state did not find any radioactive contamination
except
for a file box marked "paint sprayer" which had radiation levels twice
background.
The state confiscated the box.
The maintenance facility
transferred the paint hoses
and spray guns to Braidwood in a paste
board
box.
The Braidwood staff surveyed the received
equipment
and measured
the
following radioactivities:
Spray nozzle
5,000 dpm/100 cm'ixed
Spray gun hose 3,000 dpm/100 cm'mearable
and
5,000 dpm/100 cm'ixed

Paint sprayer
1,000 dpm/100 cm'ixed on valve
The paint spray gun hose
was the only equipment the Braidwood staff
found having smearable
contamination.
Observations
The licensee initiated
CR 97-0828
on Hay 1,
1997. to cause corrective
actions for the release of'he contaminated
materia1.
The cause listed
on the
CR was "Survey of material using current equipment
and techniques
does not assure
100 percent detection of <5000 dpm."
The
CR also stated
that the Turkey Point release
methods
could have missed the levels of
contamination
reported
by Braidwood.
'Title 10 CFR Part 20.1501(a),
requires,
in part, that each licensee
make
or cause to be made,
surveys that
may be necessary
for the licensee to
comply with the regulations
and are reasonable
under the circumstances
to evaluate the extent of concentrations
or quantities of radioactive
material
and the potential radiological
hazards that could be present.
The regulations
applicable to nuclear
power reactor licensees
do not
rovide for release of materials for unrestricted
use that are
known to
e radioactively contaminated at any levej.
The licensee's
fai lure to
detect 3,000
dpm smearable
and up to 5,000
dpm fixed radioactive
contamination
was identified as
a violation of 10 CFR Part 20. 1501
requirements (first example).
The item is tracked
as
VIO 50-250,251/97-
06-02, Failure to Control Licensed Byproduct Haterial
and Hake Adequate
Contamination
Surveys
(Painting Equipment
Released
from RCA).
The, inspectors
noted the following vulnerabi 1'ities .concerning the
licensee's
RCA exit surveys:
" The licensee did .not routinely count smears for loose contamina-
tion on materials exiting the
RCA with sample counting systems.
. The licensee relied exclusively on the thin window GH detector
for
.both fixed and smearable
contamination.
The licensee
had capabil-
ities to detect
much lower levels of smearable
contamination
(less
31
than
200 dpm/100 cm') with counting instrumentation
but relied on
detection
methods only capable of detecting
1,000 dpm/100 cm'.
The licensee's
procedures
permitted the release of porous materi-
als without any additional precautions.
A primary RCA exit and survey point did not have any counting
instrumentation.
was not enclosed,
or well lighted at night.
During the outage the licensee
assigned
and rotated multiple
vendor
HP technicians
during
a shift to survey materials exiting
the
RCA.
Radiation survey records
were not required for
HP surveyed
items
exiting the
RCA.
c.
Conclusion
The inspectors
found that the licensee's
efforts in detecting
and
measuring
contamination levels
on items released
from the
RCA were
practical
and
common.
However, the licensee's
administrative controls
and measurement
techniques
were not good enough to detect the released
contaminated material.
One violation concerning the release of contami-
nated material
was identified.

(Hx) Tubes
from the Turkey Point site.
b.
Observations
and Findin s
BACKGROUND
The
CCW system is the heat sink for many plant components
including the
Residual
Heat
Removal
Loop, Chemical
Volume Control System,
Spent
Fuel
Cooling Loop and various Reactor Coolant System components.
Makeup
water for the
CCW system is supplied from the water treatment plant
through .the sUrge tank.
The
CCW cools systems
from the shell side of
, various
Hxs.
The
CCW system "is cooled by 'ntake Coolant Water System
, entering the tubes. of, the
CCW Hxs.
'n
discussions with licensee
personnel
the inspector
learned the
. "
licensee
was replacing tubes in.all. 3 of the Unit 3
CCW Hxs in 1997.
The*CCW tubes were. 18 gauge aluminum/brass
tubes
having
a saltwater
service life of approximately .15.years
and
had .been in service'or
nearly
25. years.
Some of .the Unit 3
CCW tubes
had been replaced,.in
1991,
leaving about 1,425 tubes to be replaced in each of the Unit 3
I'
32
Hxs.
The licensee
replaced the tubes
on 3B
CCW Hx in February
and was
replacing the 3A CCW Hx in May and
3C
CCW Hx in June,
1997.
The licensee
surveyed the 3B
CCW Hx tubes for contamination
using thin
window Geiger Muller
(GM) detectors
and Micro-R Meters.
The licensee
also checked for loose contamination
using masslin cloths
and thin
window GM detectors.
The licensee
surveyed
100 percent of the external
tube surfaces
for approximately 2/3 of the
3B Hx tubes.
Since the
licensee
had not identified any contamination
on the tubes during those
surveys,
the licensee
relaxed the survey methods for the last third of
the 3B
CCW Hx tubes.
The licensee
surveyed portions of the remaining
tubes
released.
The 100 percent
survey process
had been time consuming
taking two Health Physics Technician
(HPTs) approximately
2 weeks with
some overtime to complete the task.
SEQUENCE
OF
EVENTS
The inspectors
learned that the licensee
may have released
some contami-
nated
CCW Hx tubes for unrestricted
use.
Through interviews with
licensee
personnel,
review of records,
observations.
and radiation
and
contamination
surveys the inspectors
determined the following.
On Friday May 30,
1997,
a Mechanical
Maintenance
(MM) foreman directed
MM personnel
collect
a sample the 3A CCW Hx tubes.
The mechanics
were
instructed to cut portions of the
CCW tubes to fill two one liter
marinelli beakers.
The samples
were taken
and delivered to the
counting
room that day.
A HPT working in the counting
room counted the
samples
on
a Multi Channel
Analyzer
(MCA) for 1,000 seconds.
No
radioactive nuclides were identified on sample
ID M1971390.
However,
byproduct radionuclide Co" was identified on sample
ID M2971389.
The
sample
was counted
a second time on another detector
and was identified
as sample
ID M1971391.
The second analysis of the sample again identi-
fied the presence
of radionuclide Co".
The
MCA was not setup to
quantify radioactivity on metals in a liter marinelli.
The samples
and
analysis
were made to provide documentation that the
CCW Hx tubes
were
free of all byproduct materials.'owever,
two analysis
reports clearly
identified the presence of Co" activity and listed the "quantities"
as
1.78 E-4 pCi/1
and 1.84 E-4 pCi/l.
-The
HPT that had counted the samples
reported the three
sample analysis
reports
(one negative
and two positive) were clipped together
and placed
on the Health Physics Shift Supervisors
(HPSS) log book on the HPSS's
desk that afternoon.
On the following Monday, June 2,. 1997,
an
HP supervisor-reported
finding ..
only. the 3A CCW Hx sample analysis. report that had not identified. any
'adioactive
material
on. the
CCW tubes.
Based on'the single sample
an'alysis. of the 3A CCW Hx tubes
and the survey history of the
3B
CCW Hx
tubes in February,
1997, licensee
management
reduced the survey
i equire-
ments for the free release of remaining Unit 3
CCW Hx tubes.
.33
The licensee
documented
the decision in inter-office correspondence
to
Quality Assurance
(QA) 1000 File dated
June 3,
1997.
The
memo
authorized the free release of the remaining Unit 3
CCW heat exchanger
tubes
based
on the point of origin and the following radiological
analysis:
2.
3.
4
5.
A two year chemistry history of this system
(no radioactivi-
ty);
Isotopic analysis of random tube samples.
(no activity);
Approximately 50 percent of the estimated
1500
CCW tubes
have
been
smeared
and direct frisked with no radiological
findings;
100 percent masslin wipedown;
and
Micro-R Meter of Tubes.
On Tuesday
June 3,
1997, the licensee
began releasing the 3A CCW Hx
tubes.
The HPTs assigned to survey the tubes
received verbal guidance
to masslin
(smear for loose radioactive contamination)
about
25 percent
of the external
surfaces
and to direct frisk about
25 percent of the
surfaces
with a Micro-R Meter
and
a thin window GM detector.
The HPTs
surveyed portions of the tubes
on the wagon inside the
RCA and
MM
personnel
passed
the tubes
though
a chain link fence
(RCA Boundary) to
another
MM person to load on another
wagon just outside the
RCA.
Other
HPTs passing
the work location and observing the survey
and
release
process
challenged
the adequacy of the survey process with the
HPTs surveying the tubes.
The HPTs surveying the tubes
were provided
a
copy of the June 3,
1997,
memorandum permitting the release
process.
The licensee
released
approximately
one half of the wagon that day
(approximately
350 tubes).
The tubes
were removed from the protected
area
and
dumped
on the ground
away from the site on the licensee's
Land
Utilization Area.
On Wednesday
morning June 4.
1997,
HPTs were surveying the accessible
surfaces of the remaining tubes
on the wagon inside the
RCA and waiting
'n the
MM support personnel
to arrive.
The
HPT that had counted the 3A
CCW Hx tube samples told the
HPTs that the tubes
should not be released
since they were contaminated with Co".
This information was passed
on
to HP management
and no additional
CCW tubes
were released.
The
licensee
began
an informal investigation.
The licensee
located the
sample having positive Co" and counted the sample again.
The recounts
continued to see the Co" in the sample.
The licensee
reported taking
and analyzing additional
samples
f'rom tubes .still remaining in the
'nd..that
no Co"'contamination.was
identified in those-samples.
I
"
On. Thu'rsday June '5, 1997,'he
licensee. dispatched
two Mechanical'
Maintenance
(MM) pers'onnel
to the area where the tubes were dumped to
pickup the tubes
and retur'n.then to the site.
However,'he tubes were
.
'ot
there.
The
MM personnel
foreman'also verified the tubes
were not at
the site later that day.
The licensee
reported the decision to recover
the tubes
from the Land Utilization Area was
a precautionary
measure,
in
that, the staff did not believe that there
was any contamination
on the
34
tubes.
As
a result. the licensee
decided that the recovery of the
released
tubes
was not necessary.
The licensee did not know when the tubes were removed from the land
utilization area during the period of June 3-5,
1997.
The licensee did
not receive receipts for items picked up in the area
The person that
icked up the tubes for the salvage
company reported that
he periodical-
y visited the area
where the tubes
had been
dumped for pickup of scrap
metal
and he could not remember the date
he picked up the" tubes.
On Friday.
June
6.
1997. the licensee
was satisfied that the 3A CCW Hx
tubes
were free of radioactive contamination.
The licensee
planned to
continue with the release of the tubes.
However, the licensee
reported
that no additional
tubes
were released
from the site.
On Wednesday
June
11 '997,
a conference call with plant staff was
made
to discuss
the release of CCW Hx tubes with NRC inspectors.
During the
call the inspectors
learned that the licensee
believed that they had not
released
any contaminated
material
and that they had found
a sample
contaminated with low level Co" but that they believed the sample
had
been contaminated.
The inspectors
also learned that the licensee
had
not initiated
a Condition report
(CR) and had not notified the State of
Florida oi'he incident.
The inspectors
informed the licensee that the
NRC may notify the State of Florida of the issue.
The Region II Staff
made
a courtesy call to the State of Florida the same afternoon
and
reported that
some very low level contamination
may have been released
and taken to a salvage yard in Dade County, Florida.
The State reported
that they would probably visit the scrap yard for radiation surveys
and
sample the tubes for the presence of low level radioactive
contamination.
The inspectors later determined that the licensee
initiated
a
CR 97-0985 following the conference call.
On Thursday,
June
12,
1997, the State of Florida Department of'ealth,
Bureau of Radiation Control
(BRC). visited the property of salvage
company
and
made radiation surveys of'he
CCW tubes there.
The State
personnel
did not detect
any radiation above background during surveys
of the materials.
The State also obtained
a sample of the
CCW tubes for
analysis in thei r laboratory.
On Friday, June
13,
1997, the State of Florida
BRC reported
a low but
measurable
quantity of Co" had been identified in the
CCW tube sample
they had taken at the scrap yard.
The level of radioactivity detected
was approximately 2.73 E-2 pCi/g:.
On Monday'June
16,
1997, the licensee
sent personnel
to the salvage yard
to retrieve the
3A. CCW tubes..
When. licensee
personnel
ar'rived the tubes
we'r'e already 'in a dumpster
and on
a fork lift.
The dumpster .was empti,ed..
into the licensee's
truck.
According. to licensee
personnel
the salvage
~ yard was small
and there did. not appear
to be any. other material'in the
yard resembling the
CCW Hx tubes.
The tubes
were returned to the site
'
and placed
i,n
a locked fenced .area
adjacent to the
RCA.

FINDINGS:
35
On Thursday June
26,
1997,
NRC inspectors
surveyed portions of the
returned
CCW tubes with thin window GM detector
and
a Micro R meter and
did not identify any contamination levels greater than background.
The
inspectors
also surveyed
a few of the tubes with 100 cm'mears.
The
smears
were counted
on
a low background counting system
and one the
smears
had contamination of 152 dpm/100 cm'.
The rest of the smears
(9)
did not detect
any contamination in excess of 26 dpm which was the
Minimum Detectable Activity (MDA) for the counter utilized.
The
inspectors
also sampled the tubes
and had them counted
on
a licensee
MCA
for 1,000 seconds.
The
MCA identified Co" on the
NRC inspector's
sample.
-The inspectors
concluded the tubes
were contaminated with very
low levels of measurable
byproduct contamination.
Title 10 CFR Part 20. 1801 required the licensee to secure
from
unauthorized
removal or access
licensed materials that are stored in
controlled or unrestricted
areas.
Title 10 CFR Part 20. 1501(a),
required,
in part, that each licensee
make
or cause to be made,
surveys that
may be necessary
for the licensee to
comply with the regulations
and are reasonable
under the circumstances
to evaluate the extent of concentrations
or quantities of radioactive
material
and the potential radiological
hazards that could be present.
The regulations applicable to nuclear
power reactor licensees
did not
rovide for release of materials for unrestricted
use that are
known to
e radioactively contaminated
at any level.
The licensee's
failure to
control licensed materials
and
make adequate
radiation surveys
was
identified as
a violation of 10 CFR Part 20.1801
and 20.1501 require-
ments
(second
example).
The item is tracked
as
VIO 50-250,251/97-06-02,
Failure To Control Licensed Byproduct Materials
and Make Adequate
Contamination
Surveys
(3A Component Cooling Water
Heat Exchanger
Tubes
Released
From The RCA).
The inspectors
reviewed the licensee's
management
controls for the
release of the 3A CCW tubes.
The inspectors
determined that there
was
a
breakdown in management
controls
and communication associated
with the
release of the contaminated
3A CCW tubes.
The
HP supervision staff
reported that they were unaware that two samples
had been requested
by
MM supervision
and that they had not received the two sample analysis
identifying the presence. of Co".
HP personnel
had not directly
'supervised
the sampling'f the
CCW tubes.
It appeared that the nuclide
activity. reports
having identified the'resence
of low level
contamination
on
CCW tubes
had been lost.
'One of the bases
for. the 'reduced
survey req'ui'rements
used. in releasing...
. the
CCW tubes .was that there
had not been
any radioactivity detected in
the Unit '3
CCW Hx tubes within the last two years.
However, the"
. inspectors
found that was technica] ly. incorrect in that contamination
had been identified in the
CCW system in August 1995:
.The licensee
. "-
routinely sampled the system monthly and when radioactivity was found in
36
the system, it was sampled weekly as long as radioactivity was
identified.
The licensee
had last seen radioactivity in the
CCW system
in August 1995.
Concentrations
of Na" 1.38 E-7 yCi/cc and Cs'" 2.24 E-7
pCi/cc were identified that month.
The inspectors
reviewed licensee's
responses
and corrective actions
concerning,
the release of the
CCW tubes.
The inspectors
found
management's
response
and assessment
concerning the release of the
contaminated
3A CCW tubes
was slow to recover the contaminated
tubes
and
it did not address
management
control failures or the missing sample
analysis reports.
The inspector determined the following:
Management failed to initiate
a formal review of the problem unti 1
prompted
by NRC review of the event;
Management failed to identify the breakdown in management
controls
concerning the sampling
and review of the sampling results in
thei r formal review of the event;
Licensee
had not identified missing survey records in the
corrective action program;
When there
was
some question concerning the presence of
radioactive byproduct material
on the tubes,
licensee
management
was slow in making the decision to retrieve the tubes;
and
When the licensee
management
believed there were reasons
to
retrieve the tubes
and found that they had been
removed from the
site the licensee
made
no further attempts to retrieve the
materials.
The licensee's
CR 97-0985 identified the problem as "Uncontrolled
composite sampling of 3"A" CCW Hx tubes,
and timely notification of
survey results; for determination of release of material
fro'm the
RCA.
Resulted in an allegation that material
was improperly released
from the
RCA"
The
CR identified the cause
as
"Use of RCA identifiable tools to
cut up tubes for sample analysis,
and improper notification of survey
results."
The licensee
suggested
the possibility that
a contaminated
tube cutting
tool had contaminated
the tube samples with Co" since the tool was
identified as
a tool used for work in the
RCA.
However, the inspector's
samples
of. the tubes also identified Co" and smearable
beta
and
gamma
'contamination. 'he
CR also faulted the timeliness of the technician "s
repor't to. management. that the tube. s'ample contained -Co".
The inspector
."
determined that. the counting
room HPT had followed, routine'piactices
in
. taking the sample analysis
reports to HPSS office. several
days prior to
.the. licensee.'s
decision to release
the
CCW tubes.
During the inspection licensee
management
reported that
MM personnel
were dispatched
on Wednesday
June 4,
1997, to retrieve the tubes.-
However, the inspector determined'through'interviews
with licensee
37
personnel
that persons
were not dispatched to the Land Utilization Area
to retrieve the tubes until Thursday June 5,
1997.
The licensee
reported that all of the
CCW tubes
had been returned to the
site.
However, several
persons
interviewed believed that the quantity
of tubes
returned to the site were less than the quantity released
from
the site.
The inspectors
were unable to determine whether the quantity
returned
was equal to the quantity released.
According to licensee
ersonnel
when the tubes
were released
they were approximately
15 foot
ong.
None of the returned pieces
observed
by the inspector were
15
foot in length.
Most of the tubes
were approximately
30 to 50 inches in
length and several
had been bent.
The licensee did not weigh the
material in or out.
The inspectors
were unable to determine whether all
of the tubes
had been returned to the site.
, The salvage operator
reported that all of the tubes
picked up at the dump site had been
returned to licensee
personnel.
The licensee
did not plan to unconditionally release
the remaining
tubes.
The licensee
planned to ship the tubes to a vendor for
processing
and disposal.
Conclusion
P1
P1.1
a
b
There was
a breakdown in management
controls
and communication
associated
with the release of the contaminated
3A CCW tubes.
Management's
response
was slow to retrieve the contaminated
tubes
and
their assessment
concerning the release of the contaminated
3A CCW tubes
did not address
management
control failures.
A violation was identified for fai lure to control licensed
byproduct
materials
and

Conduct of Security and Safeguards Activities
Access Authorization
Ins ection Sco
e
The inspector
reviewed
a portion of the licensee's
Access Authorization
Program
(AAP) to determine if the requirements of 10 CFR 73.56 were
being met,
as committed to in the
NRC approved Physical Security Plan.
Observations
and Findin s
The inspector
randomly selected
ten
AAP records to review and determine
if individuals'enied
unescorted
access
to Turkey Point were properly
notified and otfered
an appeal to the decision.
The inspector noted the following circumstances
during the file review:
On February
17,
1997',
an individual began the process
of
r einstating
'hei
r access
authorization
from St. Lucie to Turkey Point.
However,
due
to previous fitness for'uty 'concerns,
the individual would be entered
.into the
FP8L Conditional Access
Program..
Upon completion of the..
individual's.pre-access
chemical
screening,
which was negative,
and
additional
AAP requirements,
the individual was informed he would be
denied unescorted. access
on February,28,
1997... .."
40
The inspector interviewed licensee
representatives
and determined that
the individual would be denied
access
for the current outage at Turkey
Point.
The Site Vice President
made
a conservative
determination that
due to the short time span of the outage,
conditional
access
for
incoming employees
would be eliminated,
unless
no one else could perform
the job.
However,
upon further documentation
review, the inspector
identified that the individual was offered to withdraw his unescorted
access
authorization
request.
The withdrawal
was completed
on Harch 7,
1997, confirming that
FP8L did not deny his request for access
and the
individual would be eligible for future employment at
FP8L facilities.

Conclusions
The inspector
determined that the licensee's
AAP with respect to denial
of unescorted
access
and the appeal
process
met the requirements
