FIELD: power engineering.
SUBSTANCE: inventions are related to methods of extraterrestrial burial of radioactive wastes and to spacecrafts (SC) with an electrojet propulsion system (EPS) for transportation of these wastes to areas of burial. The method includes placement of ampoules with specified wastes into heat-conductive matrices inside a container. Heat released in them is removed by coolant of the first closed circuit to a heat accumulator and further to a hot junction of a thermal electric generator. The cold junction is cooled with coolant of the second closed circuit, removing heat to the emitting radiator surface. Electric energy produced in the generator is supplied to the EPS. The coolant of the first circuit (for instance, lithium, potassium. caesium, mercury, bismuth, or gases) is partially used as a working body of the EPS. The flow of the latter is increased in accordance with the exponential law, selecting excessive coolant above the necessary one for removal of the current thermal power. This power drops as a result of radioactive decomposition of transported wastes. The first circuit of the coolant is equipped with a thermal throttle and an electric valve and has a branch at the outlet from the container. The first outlet of the branch is connected to the inlet of the thermal accumulator, and the outlet of the first circuit is connected with the inlet of the electric valve. The outlet of the electric valve is connected with the inlet of the thermal throttle, the outlet of which is connected with the outlet of the EPS working body reservoir.
EFFECT: increased mass of transported radioactive wastes by increasing thrust of EPS and reduction of its working body mass.
