 note = {application/pdf, Diffusivity, solubility and permeability of three hydrogen isotopes and some inert gases were measured at room temperature by means of time-lag method for a polycarbonate (PC) film and PC film on which SS-304 film (100A) was coated by means of r-f sputtering. The diffusivity of hydrogen isotopes in the PC films and PC/SS-304 film decreased with an increase in the isotopes mass, however, their ratio deviated from the square root of the inverse mass ratio: the diffusivity of tritium was significantly smaller than those of hydrogen and deuterium. In addition, the solubility of the isotopes also decreased with an increases in their mass. Consequently, the permeability of tritium was 1/30-1/40 of those of hydrogen and deuterium. A drastic change in the permeability of the gases took place due to the SS-304 coating: hydrogen isotopes permeated through PC/SS304 film, while inert gases did not. The results indicate that the PC/SS304 film will separate completely the hydrogen isotopes and helium from the exhaust gas of thermonuclear fusion devices, and furthermore, it will efficiently tritium from the exhaust gases., Article},
