[en] In connection with possible application as a coolant fluid in fusion reactors, molten LiNO₃ and LiNO₃/LiNO₂ mixtures, and their mixtures with Na/K nitrates, have been evaluated with respect to their high temperature stability, their ability to reversibly dissolve and release tritium and, in a very limited sense, their corrosiveness toward structural alloys. The results of the primarily thermochemical evaluation indicate that with respect to thermal/radiolytic decomposition and corrosivity LiNO₃/LiNO₂ may be suitable for application up to about 700 degrees K; however, with respect to reversibility/irreversibility of tritium release, it appears unsuitable a all likely operating temperatures ( about 675-800 degrees K)
