作为日美联合研究计划（JUPITER-II）的一部分，进行了熔融盐Flibe（2LiF·BeF 2）中氘和氚的行为的实验研究。氘传输的测量在含有400 cc Flibe的圆柱对称双渗透探针组件中进行。柱坐标下的精确解析传输解与测得的渗透数据拟合，该分析得出氘扩散系数和溶解度系数在600 °C时分别为8.0×10− 10 m2/s和3.1×10− 4 mol/m3 Pa，在650 °C时分别为3.0×10− 9 m2/s和1.0×10− 4 mol/m3 Pa。的扩散系数约为两个因素小于以前的结果来自毛细管水库扩散测量氚。溶解度结果显著大于先前测量的D2，但与Flibe中DF的结果相当。结果表明，在这些实验中，Flibe中的主要氘运输物种是D+F−。
Experimental studies to investigate the behavior of deuterium and tritium in the molten salt Flibe (2LiF·BeF2), have been conducted as part of the Japan–US joint research program (JUPITER-II). Measurements of deuterium transport were made in a cylindrically symmetric, dual permeation probe assembly containing 400 cc of Flibe. An exact analytical transport solution in cylindrical coordinates was fit to the measured permeation data, and this analysis derived deuterium diffusion and solubility coefficients of 8.0×10−10m2/s and 3.1×10−4mol/m3Pa at 600 °C, respectively, and 3.0×10−9m2/s and 1.0×10−4mol/m3Pa at 650 °C. The diffusion coefficients were about a factor of two less than previous results derived from capillary-reservoir diffusion measurements with tritium. Solubility results were significantly greater than previously measured for D2but they were comparable to those for DF in Flibe. The results suggest that the dominant deuterium transport species in Flibe was D+F−for these experiments.
