研究了使用流化阴极工艺将 UO2 电化学还原为 U 金属的情况。进行伏安法研究，在 -1.7 V 至 -2.2 V（相对于 Ag/Ag+ 参比电极）范围内观察到还原，这可能是部分和完全还原分布的结果。当进行计时安培法时，观察到 UO2 延迟还原为 U 的诱导期（与 W 基底上的 WO3 还原相比），这可能是由于不同种 W 集电器上的“播种”步骤所致。还观察到产品剥落，并伴随着电流的减少。还原产物可以从两个区域收集：集电器上的沉积物和反应器坩埚的底部。
The electrochemical reduction of UO2 to U metal using a fluidised cathode process has been investigated. Voltammetry studies were conducted with reduction observed over the range of-1.7 V to-2.2 V (vs. Ag/Ag+ reference electrode) which may be the consequence of a distribution of partial and full reduction. When performing chronoamperometry, an induction period is observed in which delayed reduction of UO2 to U occurs (compared to WO3 reduction onto W substrate), which may be due to a ‘seeding’step onto the dissimilar W current collector. Spalling off of the product was observed as well, with associated reduction in current. The reduced product can be collected from two areas, the deposit on the current collector and the bottom of the reactor crucible.
