ABSTRACT:
The system removes heat from a vessel containing the source of heat, utilizing hot water heated by energy released in the vessel as the power supply. The hot water passes through a subcooler and a convergent-divergent nozzle of a flash jet pump where it is accelerated to supersonic velocity. Cold water is drawn into the flash jet pump by the supersonic flow generated and mixes with the water flashed into steam. The mixture is condensed and forced under pressure through connecting pipes into the pressure vessel. A second flash jet pump is utilized to initially fill the vessel with coolant water.
