Information on advance notifications of withdrawals of nuclear material from safeguards made in 2016 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|
|Four notifications involving plutonium (Pu), total mg quantities||One notification involving plutonium only and three other notifications which also involved mg quantities of uranium and/or thorium for use in analysis (e.g. as samples, standards/tracers and/or in instrument calibration) from organisations that provide standards/tracers and/or nuclear material for instrument calibration2|
|10 notifications involving high enriched uranium (HEU), total ~ 2g||Nine notifications for material contained in radiation detectors2 (from a company that manufactures radiation detectors) and one other notification for use in analysis/analytical purposes (e.g. samples, standards/tracers and in instrument calibration)2 which also involved mg quantities of depleted uranium and thorium|
|Twenty nine notifications involving depleted uranium (DU), total ~ 570kg, three notifications involving thorium (Th), mg quantities, and one notification involving natural uranium, total ~ 282g||Twenty nine notifications for depleted uranium as shielding containers3.
Three notifications involving thorium and uranium and one notification involving the return of natural uranium sources for instrument calibration2
