ABSTRACT:
The new method of removal and disposal of frozen reserve pit material, thawed reserve pit material and soils contaminated with low level radiation or other pollutants is disclosed. The system has several components that take the solids material and to crush the material down to a workable size. The crushed mixture is agitated and mixed into a slurry. Unlike other systems, the present invention uses agitation plus a jet feed of the fines slurry that is pumped into the bottom of the holding tanks. This supplemental feed assures proper dilution and ensures through mixing. The system then uses finer crushers and hydrocyclones to reduce the particulate size further. Once the material is properly reduced, it can be pumped into an injection well for disposal below ground, using any suitable method.
