Abstract:Studtite and metastudtite are uranyl peroxides formed on nuclear fuel in water through the reaction with H 2 O 2 produced by the radiolysis of water. However, it is unclear how the two types of uranyl peroxides are generated and distributed on the surface of nuclear fuel. Here, we used Raman imaging technique to exemplify distribution data of the two uranyl peroxides formed on the surface of a U 3 O 8 pellet through immersion in a H 2 O 2 aqueous solution. As a result, we observed that studtite and metastudtit… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
