Inductively coupled plasma – time-of-flight – mass spectrometry (ICP-TOF-MS) was employed for the isotopic analysis of uranium particles of varying 235U enrichment levels. Here, a single particle (SP)-based introduction scheme was employed such that individual particles ...
The MUTOMCA (MUon TOMography for shielding CAsks) international project explores the suitability of cosmic muon tomography, a non-invasive and non-destructive imaging method, for the re-verification of loaded spent fuel casks. Such casks are stored in dedicated interim storage facilities under continuous containment and surveillance by international safeguards authorities using...
The isotopic ratios of fission gas would provide important source information of a nuclear fuel sample found in the environment. However, it is believed that during a reactor accident like Chornobyl all fission gas is lost and that the radioactive particles found in the Chornobyl Exclusion Zone today are depleted in gases by the initial explosion and subsequent fire. We disprove this hypothesis by detection and analysis of ...
