A dissolution experiment is performed in order to examine the kinetics of uranium isotope equilibration in a molten salt and cadmium system. The salt contains a solute concentration of UCl₃ in LiCl-KCl eutectic and the cadmium contained dissolved uranium at 500 °C. A small piece of high enriched uranium is introduced to the cadmium, which perturbs the equilibrium with respect to the uranium enrichment of the salt and cadmium phases. The series of salt and cadmium samples trace how the enrichment of the two phases reach equilibrium (in the absence of a chemical driving force) over the course of approximately 24 h. A model linking dissolution and isotope exchange kinetics is developed to track the evolution of uranium isotope composition. With the assumption of unaccounted salt mass incurred from the dated sample reporting practice, the model explains the trend of the measured uranium isotope composition well.

进行溶出实验以检查熔融盐和镉系统中铀同位素平衡的动力学。该盐含有UCl ₃的溶质浓度LiCl-KCl共晶中的镉，而镉在500°C时含有溶解的铀。一小块高浓缩铀被引入镉，这扰乱了盐和镉相铀浓缩的平衡。一系列的盐和镉样品跟踪了大约24小时内两相的富集如何达到平衡（在没有化学驱动力的情况下）。建立了一个将溶解和同位素交换动力学联系起来的模型，以追踪铀同位素组成的演变。假定从过时的样品报告实践中产生了未说明的盐量，该模型很好地解释了所测铀同位素组成的趋势。
