Information on advance notifications of withdrawals of nuclear material from safeguards made to date in 2013 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|
|10 notifications involving plutonium (Pu), µg quantities.||Ten notifications for use in analysis/analytical purposes (e.g. samples, standards/tracers and/or in instrument calibration) from organisations that provides standards/tracers and/or nuclear material for instrument calibration2. Five notifications also involved sub mg quantities of depleted, natural uranium and/or thorium2.|
|Three notifications involving high enriched uranium (HEU), total ~ 2g||Two notifications for material contained in radiation detectors2 (from a company that manufactures radiation detectors); one 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.|
|19 notifications involving depleted uranium (DU), total ~ 394 kg and two notifications involving natural uranium (NU), total ~ 0.7 kg||Sixteen notifications for depleted uranium as shielding containers3. Two notifications for natural uranium for use in analysis/analytical purposes (e.g. samples, standards/tracers and in instrument calibration)2 and three other notifications involving g quantities of depleted uranium2.|
