The prototype showed that the performance of a novel filtration system based on super-thin basalt fiber and designed for the treatment of radioactive aerosol gasses is about 99.72%. The results fully meet the IAEA requirements.
Highly active aerosols treatment systems and a technological cycle of novel filters production have been developed by the National Scientific Laboratory named after Alikhanyan (city of Yerevan, Armenia) in collaboration with colleagues from the Armenian NPP.
Thanks to cutting-edge technologies, Most online-edition informs, scientists learned how to create super-thin basalt fiber with a diameter ranging from 1 to 3 microns, thinner than a human hair, said professor Vachagan Harutyunyan, the Head of the Department of Applied Physical Research from the National Science Laboratory.
Armenia actively uses local basalt deposits to produce, for example, basalt rebar. However, super-thin basalt fiber suitable for radioactive waste treatment can only be manufactured from a specific basalt rock, distinguished by high strength, radioactive, chemical and thermal resistance to aggressive media.
The deposits of such kind have been discovered on the territory of Armenia. Prototypes of different modifications were made of local raw materials and tested in real time on a pilot experimental setup, in parallel with the existing filters of Petryanov.
The test results showed the high efficiency of the novel system, it has sparked interest at the international scientific conferences. The price of the new technology is also attractive because the cost of super-thin basalt fiber production is reasonably low.
