Separation of protactinium from uranium-niobium alloys for 231Pa–235U radiochronometry in nuclear forensic investigations
Abstract
The isolation and purification of protactinium from uranium materials is essential for 231Pa–235U radiochronometry, but separating Pa from uranium-niobium alloys, a common material in the nuclear fuel cycle, is challenging due to the chemical similarity of Pa and Nb. Here, in this work, we present three resin chromatography separation techniques for isolating Pa from U and Nb which were independently developed by three different laboratories through ad hoc adaptations of standard operating procedures. Our results underscore the need for and value of purification methods suitable for a diversity of uranium-based materials to ensure the operational readiness of nuclear forensics laboratories.
