Application of uranium impurity data for material characterization in nuclear safeguards

Abstract

Samples of materials involved in the conversion of uranium into nuclear-grade products are collected to support the verification of States’ declarations and to look for indications of possible undeclared materials and activities. Samples are analysed by several laboratories to determine concentrations of about sixty impurities; the data consistency is addressed through the unified reporting requirements, the use of common reference materials, and via inter-laboratory comparisons. The impurity analysis results, along with other essential parameters, are interpreted to judge sample conformity to the relevant specifications, to evaluate the facility design information, to assess material provenance and intended use.
