MAMISCO Wastes Handling Magnesia-Mineral-Salt Composition
MAMISCO – a technology based on a new immobilization technology formula
MAMISCO (magnesium-mineral-salt composition) is a technology based on a new formula of the immobilizing material.
As the result of MAMISCO hardening with radioactive wastes included into its mineral matrix, a super-dense stone is being generated, whose surface is formed of an absolutely neutral micro-layer, which prevents any diffusion out of the stone’s body. This phenomenon is recognized as a scientific discovery and is protected by a certificate and a number of patents on use.
So far as the MAMISCO is actually made on the base of sea water and its surface acts as an analogue of nacre, the use of MAMISCO allows offering a self-contained technology of packaged waste disposal – in sea, in salt formations, in worked-out mines. At the same time a stability monitoring of the MAMISCO in sea water shows only an increase of strength with time.
Main characteristics of the Magnesia-mineral-salt composition
| Characteristics | GOST R 51883-2002 requirements | MAMISCO |
| Mechanical strength at pressure, MPa | 5 | 80 |
| Leaching, g/cm2 day, not more | 10-3 | less than 10-5 |
| Radiation stability – is characterized by mechanical strength, reduction of which at maximal radiation absorbed dose of 106 Gy can’t exceed 25%, at that mechanical strength have not to be below the permissible strength limit at pressure | 25% | 5.7% |
| Resistance to long staying in water – is characterized by mechanical strength, reduction of which for 90 days can’t exceed 25% at that mechanical strength have not to be below the permissible strength limit at pressre | 25% | not more than 5% |
| Frost-resistance – is characterized by mechanical strength, reduction of which at multiple freezing and defrosting (from -40C to +40 С) can’t exceed 25% at that mechanical strength have not to be below the permissible strength limit at pressure | 25% | 17% |
All our technologies are patented
The method of immobilization of radioactive structure and liquid radioactive wastes by magnesia-mineral-salt composition is patented in the Russian Federation.
