Scrubbing and storage of the gaseous wastes from a nuclear reactor

Description is given of a method for scrubbing and storing the gaseous wastes from a nuclear reactor. Three separation stages are provided: a carbon-fluoride absorber through which the gases are caused to pass, an instantaneous vaporization chamber and a separation column for isolating the absorbed gases (with the exception of krypton and xenon) and a separation column for isolating krypton and xenon. A molecular sieve is adapted to desiccate the gas to be treated; a cartridge-filter is used for expelling the radio-active substances contained in the liquid solvant; a cold drying draining device is used for expelling residual solvent vapors from the krypton-xenon mixture, and radiation detectors automatically actuate valves for recycling the mixture or storing the latter
