Supercompactor

The Supercompactor unit is intended to compact solid radioactive waste (SRW) coming in for processing in 100-liter drums for the purpose of reducing its volume, with placing the resultant briquettes in 200-liter drums to be further solidified by grouting. The compaction process is controlled with the aid of an automated control system in semiautomatic and automatic modes.

COMPOSITION OF SRW TO BE COMPACTED:

- glass, ceramic, polymer and rubber items;
- laboratory equipment;
- metal waste;
- soil, construction waste, heat-insulating materials.

Thickness of metal items in SRW – not more than 6 mm.
Content of rubber items in SRW package – not more than 7 % wt.
Content of moisture in SRW package – not more than 1 % wt.
Weight of SRW-filled 100-liter drum – not more than 100 kg.

LEVEL OF DEVELOPMENT

The Supercompactor unit has been in operation at RADON since 1999. In 2008 a new automated compaction process control system was put into operation. At present time, the Supercompactor unit meets up-to-date requirements to radioactive waste processing.
