Information on advance notifications of withdrawals of nuclear material from safeguards made in 2018 is shown in the table below. The withdrawals involved material used as radiological shielding or small quantities of material for use in instrument calibration or radiation detectors, or as analytical tracers or for research and development.
|Number of withdrawal notifications (by type of nuclear material involved)1||Reason for withdrawal|
|Four notification involving plutonium (Pu) only and three other notifications involving plutonium and/or uranium/thorium, total mg quantities||This material was withdrawn for use in analysis (e.g. as samples, standards/tracers and/or in instrument calibration)2|
|Three notifications involving high enriched uranium (HEU), total 1.6g||This material was withdrawn for use in radiation detectors2|
|Twenty five notifications involving depleted uranium (DU), total 516kg and four notifications involving uranium (U) and/or thorium (Th), total g quantities||The withdrawals of depleted uranium were materials incorporated in shielding containers3
The g quantities of uranium and/or thorium were withdrawn for use in analysis (e.g. as samples, standards/tracers and/or in instrument calibration)2
