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

本项目的目的是从化学缺陷的角度了解添加剂、掺杂剂和主要杂质对铀氧化物的化学和结构性质的影响。因此，在这样做时，可以根据所造成的缺陷及其对材料特性的后续影响，对可能的添加剂/杂质进行整组分类。如果成功，对缺陷化学知识和理解可能能够预测添加剂对氧化物性能的影响，从而能够预测潜在的新的/未来的燃料循环材料感兴趣的关键材料性能。

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.
