Using an experimental stand for studying the solubility of fluorides, measurements were performed at 550–700°C with step 50°C and the solubility of plutonium and americium trifluorides in melt with molar composition 73LiF–27BeF2 was calculated. Previously, such measurements were not performed for plutonium and americium trifluoride. The temperature dependence of the solubility of plutonium and americium trifluoride for the given salt system was constructed. The obtained solubility for plutonium trifluoride is appreciably higher than in a similar salt system with a higher content of beryllium difluoride. The obtained data on the solubility of americium and plutonium trifluoride can be used to select the minimum temperature of the fuel salt of a molten-salt reactor.

PuF3 和 AmF3 在 73LiF-27BeF2 熔体中的溶解度研究

使用用于研究氟化物溶解度的实验台，在 550-700°C 下进行测量，步长为 50°C，并计算出钚和三氟化镅在摩尔组成为 73LiF-27BeF2 的熔体中的溶解度。以前，未对钚和三氟化镅进行此类测量。构建了给定盐体系的钚和三氟化镅溶解度的温度依赖性。获得的三氟化钚的溶解度明显高于具有更高二氟化铍含量的类似盐体系。获得的关于三氟化镅和钚溶解度的数据可用于选择熔盐反应堆燃料盐的最低温度。
