device for the storage of radioactive wastes and the recovery of the heat emitted by the latter.

摘要

A storage element for use in the recovery of heat originating from the cooling of radioactive wastes including a first element for the storage of radioactive waste having a first closed shell including the wastes, and disposed within a second closed shell, both shells being of generally spherical shape, the second shell bristling with externally projecting radial points or spines, the value between the two shells being filled with a non-contaminatable fluid, promoting the transfer of heat originating from the cooling of the wastes from the first towards the second shell, of which the points or spines serve as radiators in relation to the external medium. Apparatus is also provided which includes a heat pump and an evaporator, for the storage of radioactive wastes and the recovery of extraneous heat emitted by these wastes, which includes at least one of the aforesaid storage elements in which the third shell is traversed by a cold generating fluid issuing from the condenser of the heat pump after reduction in the pressure thereof, and the outlet is connected with a compressor for delivering to the condenser, where the cold generating fluid gives up to a utilization circuit the heat emitted by the wastes and recovered within the evaporator.
