BENTONITE FOR NUCLEAR INDUSTRY
In the nuclear industry, bentonite is used as an anti-filtration and anti-migration barrier material for storage, conservation, disposal of radioactive waste and decommissioning of NRHF.
BENTONITE APPLICATION AREAS:
- Surface disposal of radioactive waste of classes 3-4
- Deep burials of radioactive waste of classes 1-2 at a depth of more than 100 m
- Decommissioning of NRHF by conservation for long-term storage
- Conservation of special radioactive waste storage facilities
- LRW plants cementing
BENTONITE PROPERTIES:
- Low hydraulic permeability
- Self-healing and self-sealing due to swelling ability
- Efficient sorption of radionuclides
- Low diffusion rates of radionuclides
- Reducing microbial activity
- Suppression of the effects of displacement of rocks on the container
- Long term mineralogical stability
