Measurement of H/sub 2/, D/sub 2/ solubilities in Zr--Al
We have measured solubility constants for hydrogen and deuterium in the Zr--Al alloy to be: K/sub H/ = exp (11.1(5)-16900(600)/T) (Torr/(Torrx1/g)/sup 2/) and K/sub D/ = exp (12.2(8)-16800(600)/T) (Torr/(Torrx1/g)/sup 2/), respectively, where K is defined implicitly by P = Kq/sup 2/ with P the equilibrium pressure (in Torr) and q the bulk concentration (in Torrxl/g). These values, in conjunction with a model for the solubility, predict that the constant for tritium, K/sub T/ approx.4K/sub H/. Consequently, the regeneration of tritium will be faster by a factor of 4 over that for hydrogen at the same temperature, or the tritium regeneration temperature can be reducedapprox.50 K compared to hydrogen for the same regeneration time.
