Popis: Thermodynamic calculations have been made to compare the thermochemical performance of three candidate breeder blanket materials, Li/sub 2/O, LiAlO/sub 2/, and Li/sub 4/SiO/sub 4/. These calculations were done for the temperature range of 900 to 1300/sup 0/K and the oxygen activity range of 10/sup -25/ to 10/sup -5/. Oxygen activity is an influential variable for these materials and must be considered in the diffusion of tritiated species, determining the chemical form of the released tritium, and retention of tritium in the condensed phase. Surface adsorption may also act as a strong contributor to tritium inventory. In general, LiAlO/sub 2/ appears better than Li/sub 2/O and Li/sub 2/O, in turn, appears better than Li/sub 4/SiO/sub 4/.
