متن کاملDevelopment of uranium reference particles to support nuclear safeguards
Controlled hydrolysis of certified uranium hexafluoride, carried out in a specifically constructed aerosol chamber, leads to the production of uranyl fluoride particulates which – deposited on a graphite planchet support may be used as a quality control reference material. The particle size and surface distribution depends on several parameters, such as the relative humidity inside the aerosol ...
متن کاملIdentification of uranium signatures relevant for nuclear safeguards and forensics
The paper describes the applicability of different characteristics (signatures) in nuclear safeguards and forensics for assessment of uranium material provenance in terms of production process. The study follows a uranium ore concentrate production from an ore to a U3O8 product. It turned out that rare-earth elemental pattern, radiochronometry (age of ore body and material production date), sul...
