Information on advance notifications of withdrawals of nuclear material from safeguards made in 2015 is shown in the table below. Data are shown in the same format as provided previously. 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|
|Nine notifications involving plutonium (Pu), µg quantities||Five notifications involving plutonium, µg quantities. Four notifications, which also involved mg quantities of natural uranium, thorium, depleted uranium and high enriched uranium for use in analysis (e.g. as samples, standards/tracers and/or in instrument calibration) from organisations that provides standards/tracers and/or nuclear material for instrument calibration2|
|There were no withdrawals of high enriched uranium (HEU)||Not applicable|
|Eighteen notifications involving depleted uranium (DU), total ~ 276 kg and two notifications involving thorium (Th), µg quantities||Sixteen notifications for depleted uranium as shielding containers3
Two notifications for depleted uranium for use in analysis/analytical purposes (e.g. samples, standards/tracers and/or in instrument calibration)2 and two other notifications involving thorium2, µg quantities
