Abstract
A spatial (3D) computer model of an isobaric phase diagram of the LiCl–PrCl3–KCl system was designed. The model was assembled of 66 surfaces and 27 phase regions, of which 31 surfaces and 14 phase regions degenerate to verticals or vertical planes because of the limited solubilities of the initial chlorides and their compounds. Published experimental isothermal sections and thermoanalytical curves for 33 salt melts were used to improve the quality of the 3D model. The results can be used to improve the molten-salt refining technology of nuclear fuel waste.
