Study on the Substitute Nuclides of Actinides in High-Level Radioactive Waste Liquid

Actinides have complex chemical properties, there are a variety of oxidation states and changeable coordination configurations, and their physical properties, electronic structure and molecular orbital theory are much more complex than other elements. On the other hand, actinides in high level liquid waste, especially transuranic elements synthesized by artificial nuclear reaction, are highly radioactive, which is critical for its stable glass solidification. At present, taking elements with similar properties as substitutes to simulate actinides and inferring the properties of actinides by analyzing the compounds formed by substitutes is one of the important works of glass solidification. This paper provides a possible way to use trivalent lanthanides as an alternative for trivalent actinides.
