ON THE POSSIBILITY OF REMOVING DANGEROUS TECHNOGENIC

摘要

The new promising mission for space rocketry is removal of most dangerous technogenic wastes outside the Earth's biosphere. The paper proposes the options of cardinal ways of saving the Earth from dangerous technogenic wastes for ever: - removal of wastes outside the Solar System; - elimination (complete destruction) of wastes by their delivery to the Sun; - burial of wastes on the asteroids which orbits never pass near the Earth. The progress achieved in the recent years in the countries of advanced nuclear industry in the field of processing low-active and medium-active parts of radioactive wastes may mitigate acuteness of the problem to some extent. However, according to the experts' opinion, this minimizes the volume of non-isolated wastes, but does not solves the problem as a whole. No matter how the used nuclear fuel may be processed, all the same, there are remaining (in small amount) extremely highly radioactive substances. Just this, comparatively small amount of substances extremely harmful for the Earth's biosphere is proposed to be removed from out planet for ever. The paper presents the options of technical configuration of the space rocket systems to remove the technogenic dangerous wastes from the Earth. The analysis is given of the today's state of solving the problem of creating a rocket module capable of preserving the integrity of a capsule with wastes in any emergency situation from the launch vehicle lift-off till the moment of accomplishment of wastes removal task. A flight experiment is proposed that can confirm integrity of the capsule with wastes in the conditions that simulate the most dangerous emergency situation, including module atmospheric re-entry at hypersonic velocity and subsequent collision with the ground. Creation of such systems will save the Earth for ever from the danger of accumulation of extremely harmful wastes.
