Considerable amounts of gaseous radioactive fission products krypton and xenon result from nuclear power generation, thus creating a radiation hazard in the event of their uncontrolled release to the environment. The most efficient method for treating off-gas streams appears to be low-temperature distillation, the efficiency of which depends on an exact knowledge of vapor-liquid equilibrium data. Isothermal data are measured for mixtures of Kr and Xe between 145 and 170 K and for their mixtures with components of air between 100 and 125 K, which make possible the exact design of a distillation column suitable for effective removal of the fission products. The solubilities of Kr in the components of air and of Xe in liquid krypton are studied, and possible applications for the safe separation and fixation of Kr are discussed.
