Renewed interest in molten Li{sub 2}BeF{sub 4} as a tritium breeding blanket suggests that a review of this solvent system is appropriate. Previous examination of this use for Li{sub 2}BeF{sub 4} was based on the data obtained at Oak Ridge National Laboratory during the molten salt breeder (fission) reactor program in the 1960s and 1970s. In discussing the thermochemistry, it is clear that T{sub 2} will be the major tritium species recovered from the blanket unless HF-resistant alloys (Hastelloy) or special coatings are used. Although T{sub 2} recovery systems have been examined, hydrogen permeation of metals at 1000 K complicates the problem. Water will not react with Li{sub 2}BeF{sub 4} to produce H{sub 2} but it does react to produce HF and BeO. 8 refs., 2 tabs.
