Summary
Thermodynamic calculations have been made to compare the thermochemical performance of the fusion reactor breeder blanket materials, Li/sub 2/O, LiAlO/sub 2/, and Li/sub 4/SiO/sub 4/ in the temperature range 900 to 1300K and in the oxygen activity range 10/sup -25/ to 10/sup -5/. In general, LiAlO/sub 2/ offers advantages over Li/sub 2/O, and Li/sub 2/O in turn appears better than Li/sub 4/SiO/sub 4/. The protium purge technique of enhancing tritium release is explored for the LiAlO/sub 2/ system. Oxygen activity is an influential variable in these systems and must be considered in executing and interpreting measurements on rates of tritium release, the chemical form of the released tritium, diffusion of tritiated species and their identities, retention of tritium in the condensed phase, and solubility of hydrogen isotope gases. Surface adsorption is seen as a potentially significant contributor to tritium inventory.
