MMSC
MMSC
MMSC – a technology based on a new formula of the immobilizing material – magnesia-mineral-salt composition. As the result of MMSC hardening with radioactive wastes included into its mineral matrix, a superdense stone is being generated, whose surface is formed of an absolutely neutral microlayer, 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 MMSC is actually made on the base of sea water and its surface acts as an analogue of nacre, the use of MMSC 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 MMSC in sea water shows only an increase of strength with time.
In the year 2003-2004 on the base of MMSC under the government contract with the foundation of development assistance for small-scale enterprises in scientific and technical sphere were carried out R&D and offered a variety of packing and immobilization technologies not only for radioactive but for chemical, toxic and organic wastes. At present, particularly, was finished the design and development work concerning ash utilization, which is generated by burning the silt sludge by the municipal unitary enterprise “Vodokanal St.Petersburg”.
In the year 2003 our enterprise won a contest devoted to the 300 years of St.Petersburg carried out with the participation of the foundation of development assistance for small-scale enterprises in scientific and technical sphere (I.M. Bortnik Foundation) with the project “Development of a technological process of immobilization of radioactive and toxic wastes by their hardening by magnesia-mineral-salt composition for the purpose of increasing of the ecological security of Saint-Petersburg and its area”. Within the bounds of the contract #4085 dated 30.04.2003 we completely finished the research. Tests were carried out on:
- Strength of the harden composition (Mining institute and halurgy institute)
- Lixiviation speed (Federal State Unitary Enterprise “LSK “RADON”)
- Radiation stability (Federal State Unitary Enterprise “LSK “RADON”)
- Resistance to a prolong stay in water (Scientific and Technical Complex “Nuclear-waste disposal in salt formations”)
- Frost resistance (Federal State Unitary Enterprise factory “Dvigatel’”
The received characteristics allow speaking about the achievement of a qualitative new level of material used for radioactive wastes immobilization. As a result of this work core enterprises (such as Federal State Unitary Enterprise “LSK “RADON”, Federal State Unitary Small-Scale Enterprise “Zviozdochka”, Research and Engineering Institute of Electrotechnology of Dollezhal) have shown their interest. There is a certain export potential so far as the cost of the made composition is much lower () than of the well-known material “SINROC”, but then it excels the more expensive one in qualitative characteristics.
The method of immobilization of radioactive structure and liquid radioactive wastes by magnesia-mineral-salt composition is patented in the Russian Federation (Patent #2212070 and #2214011). The packing of different types of ash is priority protected dated 20.02.2008 #2008108139/06(008804)
Efficient material for wastes immobilization
- MMSC – made of widespread natural minerals or wastes of metallurgical and halurgical production.
- MMSC – exceeds the requirements lodged for materials under GOST R 51833-2002 exposed to all types of influences.
- MMSC – don’t need high power inputs, as by vitrification. This characteristic is similar to power inputs by cementation.
- MMSC – used on serial standart equipment.
- MMSC – exceeds the “SINROC” material by main consumer characteristics, and has a much lower cost price.
- MMSC – has a special layer of high strength and low porosity on its surface.
