2.0 Purcose The purpose of this inspection was to. review the lit;nsee's
. radiological controls program with' respect to the following
.
elements:
organization and staffing,. training and
.
l'
qualification of personnel, procedural' maintenance
]'
practices, applied health physics, and.the "As Low As
"
Reasonably Achievable" (ALARA) program.

i:
3.0 Orcanization and Staffina
,
The individual who held the position of Assistant Health L'
Physicist during the'last radiological control inspection H
has been transferred to PECO's Peach Bottom Atomic Power
)
Station.
During the inspection period ~this position was j'
-vacant.
The Dosimetry Physicist position has been vacated since the last inspection period.
The position is now being filled by an individual-from the corporate radiation protection office.
L Six HP Shift Supervisors equally share the responsibility for implementation of the applied HP program.
The lead'
j position'is shared by the supervisors on a rotating schedule.
. Licensee management personnel consider the proper selection of first line supervisors to be essential to the j
success of the organization.
Specific experience and
,
educational requirements restrict candidates who have not demonstrated technical ability from applying for supervisory

roles.=. Technically qualified candidates are evaluated through an " Assessment. Center" where leadership,
' communication, organization and other-non-technical skills are tested.
No-weaknesses were identified by the inspector in this area.
~
W 4 '. 0 Trainina and Oualification of Personnel-j Several personnel in the Health Physics. Organization have
,
received extensive plant systems training including-Senior i'
Reactor' Operator _ certificates.
An individual in the Radiological-Engineering group has been qualified as a i
,
,
Limited Senior Reactor Operator (LSRO). _As an LSRO, this 4 -
individual was ableito manipulate' fuel bundles during the~
.1990 Unit'2 refuelling outage.
The station's willingness to
provide diversified. training'to' health-physics personnel is i
considered a good initiative.
Although the health physics
,
staff is generally well trained in plant operations, the inspector.noted cases where.some management personnel have 1'
received little or-no training in power plant systems.
The minimum course. length for plant' systems training is three.
weeks.; PECO plans to. provide plant systems training-to the entire staff as. schedules permit.
Radiation Protection
- Technicians also have the opportunity to gain experience peripheral to-their normally assigned duties.-
Individuals t
.have'been placed on long. term assignment'within the
,"
maintenance-organization _as planners and valve repair team u
members..'The inspector noted that these initiatives have resulted in a more. consistent. approach toward the
,
. establishment of radiologicalLcentrols, improved
"
interdepartmental communication and cooperation, and a
.better understanding of other disciplines.
Professional' staff training was provided in the following
'
areas:
Beta Dosimetry, Radon Analysis, Effluent Sampling, i
L Gamma Spectroscopy, Internal Dosimetry, Air Sampling, and H6 Whole Body Counting.
Although'many individuals have yet to receive this training, no specific weaknesses were noted
,
during the course of the ir.apection regarding the technical
'
abilities of the professional staff.
During a previous inspection, the inspector reviewed the l
program for training and qualification of HP_ personnel and found several. discrepancies between'two existing station
'
documents.
These discrepancies were' rapidly corrected during the last inspection period.
The inspector found no discrepancies in a review of station procedures during this inspection.

p 5.0 Aeolied' Health' Physics j
The inspectors toured the RCA-several times during the
.
inspection period.
Radiological. postings were found to be
~
accurate and well maintained.
Housekeeping was in good H
order for outage conditions.
The temporary shielding-installations observed in the drywell were effective in reducing local area dose rates.
During inspection of these
'
installations.it was apparent that success in this area is the result of. excellent planning efforts.
Shield supports were prefabricated to facilitate rapid' installation and removal and to relieve the loading on plant systems.
The station is. piloting a study-on the use of a new type-of
.
i disposable protective clothing.
The coveralls are made of a grey " breathable" material and have the. feel of a standard
. paper coverall.
The inspector found the material to-be comfortable and water repellent.
If the material is abraded some of the water repellent properties are lost. :The strition'is studying this material for heat stress-considerations as well as radwaste reduction.
This-
'd!sposable protective clothing may be incinerated.
The
inspector will continue to evaluate the adequacy of this new
. material in future-inspections.
LThe first stage of a new computerized health physics data system has been implemented.
The system currently provides a near instantaneous display of personnel in the drywell at any time, rapidly incorporates estimated exposures into the.
>
exposure tracking system and allows more rapid exit from the m
drywell.
The inspector will evaluate this system as-additional' modules are implemented.
6.0 ALARA
The site ALARA program was discussed with the Radiological Engineering Supervisor.
The program hinges on'HP planners located in the maintenance. department.
These HP personnel
,
are dedicated tc the maintenance department to facilitate L'
- communication and cooperation ~between the two departments.
-The HP planners provide the initial 1 determination regarding the level of ALARA review.
For work where the exposure projection is:1 man-rem or less with dose rates less than 30 mR/hr, the applied health physic personnel incorporate ALARA i
concerns into the RWP.
For work with an exposure projection
'"
of 1 man-rem or more and dose rates greater than 30 mR/hr, the HP planner contacts the Radiological Engineering
'
Supervisor who in turn assigns the ALARA review to the appropriate Radiological Engineer.
The method allows the HP planners to ensure that the projected man-hours and work scope is both consistent and accurate.
The inspector L

considered this practice a program strength.
A nine day training course was held for the maintenance planners.where a couple modules. covered Health Physics
,
s A issues specifically.
This type of training promotes an.
understanding of health physics concerns and-responsibility for ALARA concerns at the individual level.
TheLinspector. reviewed 1990 annual exposure projection.
The projection is 270_ man-rem-for the station.
However, the amount of exposure expended at the start of the outage was approximately 35 man-rem less than the projection.
The station therefore established a target exposure of'less than 235 man-rem for 1990.
At the time of the inspection, only.
'
76.3 man-rem had been' expended.
This is well under the projection and-seems to indicate that an station target
exposure of.'less than'235 man-rem is attainable.. The
inspector reviewed the 1990 annual: exposure projection for each. department andLnoted that'all the departments were under the projected exposure for the year.
7.0-Exit-Meetina A meeting was held with licensee. representatives at the end
.of.this inspection on October 5, 1990.
The purpose.and
'
scope of the inspection were reviewed and the findings of s-the. inspection were discussed.
