This unique macroencapsulation system uses a
resistance wire system embedded in the lid of a polyethylene
container.
Once the waste form is placed into the container, the lid
is placed on the container and the wiring in the lid is
connected to a control unit. |
| With the touch of a single button, the
control unit allows a specified amount of electrical current
to flow through the resistance wires for an exact amount of
time. This causes the wires to heat up and melt the
polyethylene in the lid and container, effectively welding the
lid onto the container. There is no steel ring to rust
off or any gasket to fail. The waste has been
encapsulated.
|
| Custom sized containers of virtually any size can
be molded to meet specific needs. Containers can be made of a
100% polyethylene construction or with a steel exterior and a
bonded interior liner. Materials for filling any
interior void areas of the waste form are also available. |
|
| The EPA considers
Macroencapsulation a treatment (40 CFR 268.45) for some forms
of waste such as debris waste and lead.
Macroencapsulation is also a treatment being used for some
forms of Mixed Radwaste.
The Ultra-MacroEncapsulation System can be performed
remotely and has been used in container sizes as large as
52" diameter x 20' lengths (at the INEEL site, Idaho). |
