RADIOGENIC HELIUM SEPARATOR Russian patent published in 1998 - IPC

FIELD: chemical engineering. SUBSTANCE: invention is meant to be used in high-temperature nuclear- power plants with chiefly space-destination lithium heat carrier. Lithium with dissolved radiogenic helium is passed through capillary structure with intrinsic dimensions determining small distance of the diffusion of radiogenic helium atoms in lithium and therefore acceptably small time constant for isolation of helium from lithium. On the separator inlet, there is capillary gate and, on the outlet, metal-felt filter are installed. EFFECT: facilitated helium separation. 9 cl, 1 dwg
