Production and Characterisation of Microparticle Reference Materials for Particle Analysis in Nuclear Safeguards — •Stefan Neumeier, Philip Kegler, Martina Klinkenberg, Irmgard Niemeyer, and Dirk Bosbach — Forschungszentrum Jülich GmbH, Institute of Energy and Climate Research * Nuclear Waste Management and Reactor Safety (IEK-6), 52425 Jülich, Germany

The International Atomic Energy Agency (IAEA) implements safeguards measures in order to verify that member states are in compliance with their international legal obligations to use nuclear material and technology only for peaceful purposes. Safeguards measures, inter alia, include analytical measurements of samples taken during inspections at nuclear facilities. While the use of analytical techniques by the IAEA constantly requires quality control and further advancement, particle reference materials are needed for enhancing particle analysis methods in safeguards. This presentation reports on the development of an installation at Forschungszentrum Jülich capable of the production of microparticles, which are intended to be used as source material for certified reference materials. The first part of the presentation addresses the process development and optimization, e.g. influence of precursor chemistry on particle morphology. The second part discusses the particle characterization and analysis by electron microscopy, mass spectrometry and µ-X-ray methods.
