Certification of the First Uranium Oxide micro-particle reference materials for Nuclear Safety and Security, IRMM-2329P and IRMM-2331P
For nuclear safeguards purposes, two new uranium micro-particle isotope reference materials were certified, IRMM-2329P and IRMM-2331P, with 235U enrichments of 3% and 5% and 236U abundances of 30 ppm and 60 ppm, respectively. The isotopic compositions of the base materials were measured by TIMS using the modified total evaporation method. The production of the uranium particles was achieved using a vibrating orifice aerosol generator (VOAG) and the particles deposited on carbon planchets. Process control verification measurements on dissolved uranium particles were performed by MC-ICPMS. For IRMM-2329P also the uranium amount per particle was certified by TIMS/IDMS and verified by MC-ICPMS/IDMS.
