Polyethylene was tested and evaluated as a radwaste immobilization
media; recommendations are given on sodium sulfate, boric acid,
incinerator ash, and ion exchange resin wastes.

A polyethylene encapsulation system for treatment of 1ow-Ieve1
radioactive, hazardous, and mixed waste has been developed and appears
to offer several advantages over more conventional methods such as
cement.

Cemented waste is impregnated with a Iow viscosity polymer such as
styrene after the cement has been cured. The catalyst (benzoyl
peroxide) is then added at 0.5 wt% and the material polymerized within 3
to 4 hours at 50 to 70'C. Product leaching performance is improved a
factor of 100 and compression strengths are 3 to 10 fold higher.

Sulfur Polymer Cement was tested as a radwaste solidification agent. It
appears to produce an acceptable waste form and recommendations for
sodium sulfate, boric acid, and incinerator ash wastes are provided.
