Two of the contractor specialists signed in on the RWP to set
8
up for transfer of the source vial.
1545
Technician P entered on the RWP to measure dose rates, using
a teletector and ion chamber, during transfer of the source
from the cask to the mixing bottle. The protective clothing
requirements for the job included cotton boots, rubbers, lab
,
coat, face shield, and surgeon's gloves. Technician P was
wearing cotton boots, rubber shoe covers, cotton glove liners
'
and surgeon's gloves.
1557-
De source vial was removed from the cask shield and
transferred to the lead holder by the contractor specialists. At
this time unnecessary personnel retreated due to the expected
high dose rates. The cap to the vial was removed and the
contents of the vial were transferred to the mixing bottle. . The -
vial was then returned to the lead vial holder.
1600
Technician P then surveyed the area (dose rates and smears)
and inappropriately replaced the cap to the vial. This was a
spontaneous action. One of the contractor specialists tried to
stop him, but was too late. This action was not observed by
other radiation protection personnel in the area.

The technician alarmed the whole body monitor at the RP
Office. Proceeded to frisk himself, contaminating the frisker~
probe. Two others (a technician and a supervisor) sustained
low level hand contamination from this action.
1625
Technician P was assisted by the shift technician, a chief .
technician, and a supervisor. The initial dose rate reading from
the technician's thumb was approximately 120 mrad /hr at one-
eighth inch using an RSO-50 ton chamber. Technician P was
decontaminated initially using soap and water.

1.2
CAUSES, WEAKNESSES AND CONTRIBUTING FACTORS:
1.
Inadequate assessment of potential risks and reduction of
protective clothing. Initial RWP preparation had identified full
P.C.s to be worn. He ALARA review process reduced P.C.
requirements (due to convenience?) since they failed to consider
the potential for major contamination resulting from a spill, leak
or improper handling of the source. The ALARA process focused
on external exposure hazards only and contamination controls
were minimal. As a result the pre job briefing was inadequate.
2.
Personnel from the ALARA staff, properly qualified in radiation
protection procedures, prepared the ALARA review, developed
,
the radiation work permit and provided the job coverage. This
produced a condition in which the normal independent review
relationship between the operational radiation protection group
and the ALARA group was bypassed and protective equipment
requirements were inappropriately reduced.
3.
Technician and staff training (at least for this individual) was
inadequate or ineffective in that personnel did not recognize the
contamination potential associated with this source and the high
beta dose rates that could be encountered.
]
4.
The technician providing job coverage acted outside his role as a-
monitor and assumed the role of a worker in handling the source
vial cap contrary to previous rehearsal in mockup training. The.
technician's protective clothing was inadequate for the activity that
he undertook.
5.
The technician aggravated the contamination event by failing to
obtain assistance from other radiation protection personnel when
extensive contamination was detected.on his person.
6.
Procedures for this evolution were weak in that there was
extensive cross referencing to vendor procedures and references to
radiological control requirements were _ vague (Example: "the
-
evolution will be performed in accordance with radiation
protection procedures...").
7.
Due to the need for timely completion of this test concurrent with
pre-outage preparations, a task of major radiological significance
was undertaken with an already high workload, possibly reducing
the level of review.

ANALYSIS OF RECENT SIGNIFICANT RADIOLOGICAL EVENTS
AT FITZPATRICK
2.1
ADVERSE RADIOLOGICAL EVENTS:
A.
EXTREMITY OVEREXPOSURE EVENT - February 1987
Inspection 50 333/87 07; LER 50 333/87-002-00
Summary:-
During the replacement of dry tubes in the reactor vessel, a contractor
reactor service technician received an extremity dose to the right hand of
29.6 rem while performing maintenance on a dry tube cutting tool.
During the cutting activity, a piece of the dry tube became trapped in
the cutting tool. . The dry tube fragment fell onto the refuel floor when
the tool was removed from the spent fuel pool. The exposure event
occurred when the reactor service technician picked up and handled the
irradiated dry tube fragment. The radiation protection technician
assigned to cover the job did not monitor dose rates as the tool was
being removed from the water. Instead, he assisted the workers by
holding a hose to rinse the tool as it was being removed from the pool.
Causes, Weaknesses and Contributing Factors:
O
1.
Multiple communications breakdowns
2.
Poorly defined authorities and responsibilities
(Technician acted more as worker not monitor)
3.
Failure to survey
4.
Failure to follow procedures - Workers violated RWP
requirements; workers did not conduct pre job briefing as
required; ARM local alarm was disconnected and not documented
as a jumper; leadman did not ensure worker compliance with
RWP requirements.
5.
Inadequate training
Personnel did not understand the magnitude
of the source associated with irradiated core components; staff
had little prior experience with this activity.
6.
Inadequate procedures
Hold points were not identified;
authorities and responsibilities were not clearly delineated;
response to alarms not addressed; ALARA review did not develop
i
"what if" scenarios; high range extendable probe survey
instruments not specified.
O.
7.
Failure to implement previously identified corrective actions.

1989 Inspection 50 333/8913
Samatary:
During a spent fuel pool cleanup campaign two contractor personnel
received unplanned radiation exposures when a small high activity source
floated to the surface of the spent fuel pool.
Causes, Weaknesses and Contributing Factors:
1.
Inadequate control of materials introduced into the spent fuel
pool such that a floating hot particle source could develop.
2.
Inadequate equipment (installed area radiation monitors).
3.
Inadequate use of equipment (alarming dosimeters, portable
ARMS).
4.
Inadequate assessment of potential risks (i.e. potential for floating
hot particle).
Mitigating Factors:
Q
1.
Prompt and conservative action by the radiation protection
technclan once high dose rates were detected (evacuation).

SUCCESSFUL RADIOLOGICAL EVENTS AND ACTIVITIES
8
A.
1988 CHEMICAL DECONTAMINATION PROGRAM
Summary:
'In August September 1988 the FitzPatrick staff successfully completed
two chemical decontamination efforts using the I.OMI process: a-
demonstration program on portions of the RHR system and a larger
decontamination of the reactor water recirculation system and certain
attached piping. ' Ibis project involved the removal of over 61 Ci of
activity from plant systems and established record-setting
decontamination factors for dilute reagent chemical decontaminations.
During this project, there were no radiological incidents or aersonnel
contamination events despite the high potential for r> cess
enks and
transient dose rates produced during this process. 3e collective dose,
although somewhat higher than originally projected due to pre-
decontamination dose rates in the drywell, was controlled effectively and
the projected dose savings from the combined efforts was approximately
700 man rem in 1988.
One event, involving the incomplete cement solidification of LOMI lon
exchange resins, resulted in a civil penalty from the State of South
O
C rolina and a corresponding Severity Level III violation from the NRC.
This event was subsequently determined to be generic in nature and
involved the adequacy of the NRC accepted Process Control Program for
the cement solidification of LOMI generated ion exchange resins.
i
Successes:
1.
Significant risks associated with this activity were recognized
clearly at the beginning of the project.
2.
An interdisciplinary project team was assembled at the beginning
of the project and roles and responsibilities were clearly defined.
3.
Since the staff had no prior experience with this activity, the -
services of consultants with extensive experience in chemical-
decontamination were obtained to independently review vendor
y
procedures and assist in monitoring vendor performance.
4.
An experienced member of the plant staff acted as the project
coordinator during the on site mobilization and operational phases
of the effort.

Negatives:

1.
The radwaste solidification problems encountered in this project
were previously unknown to the Fitzpatrick Staff and were not
generally known in the industry. The existence of an NRC.
accepted Topical Report on the solidi 6 cation of LOMI wastes was
used by the radwaste solidi 6 cation vendor to provide assurance
to the Authority that solidification issues were addressed
adequately. Following discovery of this problem, the Authority
initiated a comprehensive corrective action program that included
research and development into the chemica mechanisms
responsible for incomplete solidi 6 cation and )roposed alternatives -
that are pending publication by the Electric Power Research
Institute.
- Analysis:
With the exception of the radwaste solidification issues, The Authority
demonstrated the ability to control non routine radiologically significant
tasks involving high activityE significant contamination stential (i.e.
greater than 1 uCi/100 cm ) and transient and potent:. ally high dose
rates.

CORE SPRAY DOWNCOMER REPAIR
Summary:
ISI performed during the 1988 refueling outage identified a
circumferential crack on a 4 inch Core Spray downcomer inside the
reactor vessel, approximately 6 feet above the top of active fuel. The
crack was not detected until fuel loading was approximately 2/3
complete. Due to the nature of the crack, the repair program required
dry hands-on welding to install a " clamshell" and restore structural
integrity.
This work involved relatively high dose rates (1 to 3 R)'hr general area
and 5 to 8 R/hr at contact. Contamination levels were 110 Ci/100
cm'. The initial dose projection for this effort was 25 man rem with a
potential for high airborne radioactivity during the weld repair.
The repair plan was successfully implemented using a collective dose of
only 11.5 man rem. There were no personnel contamination events and
no radiological incidents.
Successes:
1.
Significant risks associated with this activity were recognized
clearly at the beginning of the project.
2.
An interdisciplinary project team was assembled at the beginning
of the project and roles and responsibilities were clearly defined.
3.
Extensive mockup training was Mrformed to select qualified
welders, develop good work tec;miques and assess the adequacy of
personnel dosimetiy.
4.
A comprehensive ALARA package was developed to minimize
worker doses and engineering controls to minimize airborne
radioactivity were developed.

RES DEPARTMENTAL MANAGEMENT ASSESSMENT (1989)
,
Background -August 1989, the OA Superintendent and Vice President Nuclear
Support were requested to conduct an assessment of the
.,'
Radiological Environmental Services Department, focusing on
3
4
management issues.
t
8
This assessment involved interviews with 40 members of the'RES
- i
Department Staff.-
Results
~
- This audit documented a number of weaknesses in'the RES
!
Department oreaah= don including:
}
A.
Management process de5clencies including the need to:
improve RIR critique feedback to RES technicians and line
staff, accountability of all personnel for radiological
-i
a
performances.
B.
Organizational improvements needed to strengthen the-
operational radiation protection function, supervisory oversight
and use of senior union posidons (Chief Technicians).-
C.
Training im
,
technicians.provements needed for both supervisors and
The present union position that combines-
radiological nrotection and chemistry
needs to be ' split in order to improve / environmental functi
the depth ofinitial and
contim:ing training. ,
,-
-
,t
D. Extensive use of long-term contractors including contract
.
l
supervisors. Contractors and temporary employees are used
almost exclusively in some areas of significant radiological
risk (e.g. refuel floor). Permanent staff resources need to be-
l-
re decated to address this deficiency.
E.
l
Communications between management and union. personnel
,
such as the lack-of regularly scheduled department meetings,
feedback on enforcement of radiation protection standards-

OVERVIEW WEAKNESSES, ISSUES AND CORRECTIVE ACTIONS-
4F
Organisation and Manage:nent Philosophy
A. Issues
i
i
1) Management philosophy of identifying and resolving problems and'
l
insisting on high performance standards is weak.-
2) RES organization does not provide balanced work requirements 1and.
responsibilities consequently, certain groups overworked.,
u
~
3) Several individuals have been performing same function for. years-
and, therefore, not learning from cross training. This may lead to
a " status-quo" mentality.
4) Communications between supervision and union personnel
i
expectations, how to improve standards of perfo.mance etc. has
L
been weak.
l
B. Corrective Action
'
O
1) New RES Superintendent placed in 1989.
2) Organizational improvements / rotation being. developed-for
implementation after outage.
i
,
3) Higher standards being implemented and' accountability being -
i
increased.

Present Union Job Description
!
A. ~ Issues
.
-
1) The present combined RES technician (i.e. radiation.
f
- protection / chemistry / environmental) position restricts ability to.
concentrate training and qualification in one area.
f
.
2) Present technician position has minimal entry level requirements'
'
(i.e. high school graduate) which places burden on training and line
.
organization staff.-
,
.
.
L
B.- Corrective Action

,
1) Negotiations =have commenced with union to split RES technicians
~

<
A. Issues
,
1) After four (4) years of apprenticeship program, scope of combined '
technician program too broad for a minimal _ entry level candidate.
2) Continuing training programs are weak 'due;to necessity of -
malatalning quali6 cation in all areas. 'Ihis particularly impairs
ability to focus on operating experience issues.-
3) Supervisory knowledge and interface with program has-been weak.'
4) Supervisory participation in relevant portions of training program
has been minimal.
B. Cor1nsetive Action'
'
1) Upon agreement with union on job description, rewrite qualification
program requirements.-
2) Assess adequacy of Training and RES staffs as part of program
-
redefinition. '
3) First line supervision will attend applicable training following the
1990_ Refuel Outage.

,
~
A. Issues .
f
-.
.
,
- 1) Some technicians and supervisors while perhaps understanding
theoretical aspects of radiological risks, do not implement necessary
'
precautions in the 6 eld.1May be due to. training, past practices,'
lack of reinforcement..
.
.
.
2) Some technicians and suwrvisors have reduced radiological
'
-
--
,
-protective measures (or failed to increase protective measuresi
during higher risk evolutions) for convenience without a reasoned -
,
assessment of risk _vs protective measures, ALARA,' personnel
!
safety, etc. -
3) The plant's ALARA program (and radiological work permit review -
- 3
program) is focused on man rem assessment and reduction and not
'
on overall radiological risk (exposure, contamination, etc.)
-
assessment and reduction. '
B.. Corrective Action -
'
1) Training needs to focus (especially in continuing training)
understanding radiological risks especially for infrequent or. " fir
time" evolutions.
'
2) RES personnel have been made aware of issue of reduction of.
H
protective requirements for. convenience (many had not thought of
y
this before). Continued emphasis and review of this issue is
1
4
required. (Third party assessment of certain tasks will be used as
an interim measure until long term corrective actions are in place).
3) ALARA review process will be upgraded to require escalated
management review and approval for radiologically significant tasks
beyond the current colleedve dose requirements. ; Specific review
criteria and radiological assessments will be included to consider--
possible accident or- abnormal scenarios and-to develop appropriate
contingency plans. The escalated management review cnteria will-
consider both the potential severity'of adverse consequences and
decreasing level of experience with the activity.

1). Some evidence exists that corrective actions resulting from RIR-
critiques are not-being properly implemented (i.e. intent not being
accomplished).
2) RIR and self assessment' programs have a. lot of data concerning
"who, what, when"; however, trending of courses is weak.:
Valuable' data is not being developed and trended. .
3) The majority of assessment programs focus on programmatic-
-issues and results rather than technique and real' time
performance.

Establishanent of Formal Project Tenans.
A. Issues
1) Determination of what events should involve a forrnal
interdisciplinary project team (when RES is one of support) is-
a
undefined. Surely a chemical decon and (now we realize) fuel pool-
cleanup should be in this category, but should an evolution like the:
Na-24 feed test be included?.
