Pyroprocessing using molten salts offers a range of advantages when compared to aqueousprocessing. These include a smaller footprint of facilities, better criticality safety margins, and shortercooling periods for irradiated fuel. The final product is normally of high purity.UCL have pioneered the use of fluidised cathode electroreduction and successfully applied thissystem to challenging materials. In this project, the ultimate aim would be to apply it to reduce a smallquantity of plutonium oxide at AWE premises. The bulk of the project will be in reducing surrogatematerial oxides to their metal form using different precursor types, such as packed solid, liquid bed,and the fluidised cathode, with the objective of improving reactor and electrode design andperformance along the way.

与水性过程相比，使用熔融盐使用熔融盐的旋食物具有一系列优势。其中包括较小的设施占地面积，更好的关键性安全利润以及用于辐照燃料的短路。最终产物通常具有很高的纯度。UCL率先使用了流化的阴极电动量，并成功地将本该系统应用于具有挑战性的材料。在这个项目中，最终的目的是将其应用于减少敬畏场所氧化p的少量。该项目的大部分将是使用不同的前体类型（例如填充的固体，液体床和流化的阴极）将替代血小板氧化物降低到其金属形式，目的是在途中改善反应器和电极设计和性能。
