Chemistry in support of fusion reactor technology
Equilibria in hydrogen--isotope--controlled thermonuclear reactor (CTR)- blanket systems were studied. Data are tabulated on: equilibrium in liquid Li-- hydrogen-isotope systems; calculated equilibrium constants for the Li(g) + $sup 1$$/$$sub 2$$H$$sub 2$(g) = LiH(g) equilibria; and calculated equilibrium concentrations for the vapor species Li, T$sub 2$, and LiT in a CTR. A mixed- isotope technique and the associated apparatus were developed for measuring the permeation of tritium through metals under simulated steam-generator conditions, and tested by measuring tritium permeation through clean nickel at 636 to 910$sup 0$K. The effect of an oxide film on impeding the permeation of tritium through Incoloy 800 was also studied. Tests indicated that the Ce(III)/(IV) redox couple is not a suitable buffer for reducing TF to T$sub 2$ in a CTR blanket composed of Li$sub 2$BeF$sub 4$. (JGB)
