Information on advance notifications of withdrawals of nuclear material from safeguards made in 2017 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|
|One notification involving plutonium (Pu) only and one other notification involving plutonium and uranium (U), total mg quantities||This material was withdrawn for use in analysis (e.g. as samples, standards/tracers and/or in instrument calibration)2|
|Five notifications involving high enriched uranium (HEU), total 2g||This material was withdrawn for use in radiation detectors2|
|Twenty three notifications involving depleted uranium (DU), total 491kg and five notifications involving uranium (U) and/or thorium (Th), total mg quantities||The withdrawals of depleted uranium were materials incorporated in shielding containers3
The mg quantities of Uranium and/or Thorium were withdrawn for use in analysis (e.g. as samples, standards/tracers and/or in instrument calibration)2
