- Abstract
The accurate interpretation of uranium metal 230Th/234U and 231Pa/235U radiochronometry model ages requires an understanding of how uranium parent nuclides and decay progeny (230Th and 231Pa) behave during uranium metal casting. In order to directly measure the spatial distribution of 230Th and 231Pa in uranium metal before and after vacuum induction melting (VIM), Los Alamos National Laboratory identified uranium metal feedstock, characterized the metal feedstock, conducted a controlled casting experiment of an approximately 120 kg uranium metal rod, and characterized the cast metal. This study presents radiochronometry results and quantified 230Th and 231Pa VIM separation factors from bulk uranium.
