Effects of additives and dopants on the chemical and structural properties of U oxides

该项目的目的是了解添加剂、掺杂剂和主要杂质对铀氧化物化学和结构性质的影响，从化学缺陷的角度造成的。这样做，就有可能根据所引起的缺陷及其对材料特性的后续影响对整个潜在添加剂/杂质组进行分类。如果成功的话，对缺陷化学的知识和理解将有可能预测添加剂对氧化物性质的影响，从而预测潜在的新/未来燃料循环材料的关键材料性质。

The aim of this project is to understand the effects of additives, dopants and major impurities on the chemical and structural properties of uranium oxides in terms of the defect chemistry caused. In doing so, it may therefore be possible to classify whole groups of potential additives/impurities in terms of the defects caused and their subsequent effect on the material characteristics. If successful, that knowledge and understanding of the defect chemistry could potentially enable the prediction of an additive's effect on oxide properties, and hence the prediction of key material properties of interest for potential new/future fuel cycle materials.
