Radiological Safety Training for Plutonium Facilities
DOEHDBK11452001
Student's Guide
The best way to maintain contamination
control after a loss of containment is to
decontaminate to low or non-detectable
levels. However, in some instances,
contamination must be fixed in place. This
is usually done by painting the surfaces of
gloveboxes, walls, floors, etc. Because
there is a potential for contamination control
problems if these surfaces are disturbed,
individuals should not scrape surfaces or
remove tape unless precautions are taken.
D. Criticality controls
Many facility-specific engineered and
administrative controls have been put in place
in an effort to prevent an uncontrolled criticality.
This course does not provide adequate training
in the handling of fissile material. Examples of
engineered controls are specific piping,
container shape, and poisons (neutron-
absorbing material). Examples of
administrative controls are procedures on
container spacing and the amount of material in
the container.
Only workers who are properly trained
should handle fissile material. If you are not
trained as a fissile material handler, do not,
under any circumstances, handle fissile
material.
Because liquid containing plutonium is a
special criticality concern, care must be taken
when handling plutonium-bearing liquids.
Containers that could hold liquid must not be
placed in or under gloveboxes or hoods unless
they are criticality safety approved.
