Information on advance notifications of withdrawals of nuclear material from safeguards made during 2002 is shown in the table below. Data are shown in the same format as those provided previously. The withdrawals involved small quantities of material for use in instrument calibration or radiation detectors, or as analytical tracers or radiological shielding.
| Number of withdrawal notifications (by type of nuclear material involved)1 | Reason for withdrawal |
|---|---|
| three notifications involving plutonium (Pu), µg quantities | material to be used for analytical purposes (e.g. samples, standards/tracers and/or in instrument calibration)2 (all from NPL Teddington) |
| three notifications involving high enriched uranium (HEU), total ~6g | for material contained in radiation detectors2 (all from Centronic Ltd) |
| five notifications involving depleted natural and low enriched uranium (DNLEU), total ~27kg | three for material for use as radiological shielding (two from High Technology Sources Limited and one from UKAEA Harwell) and two for material to be used for analytical purposes (e.g. samples, standards/tracers and/or in instrument calibration)2 (from NPL Teddington) |
1 tabulated information covers advance notifications of withdrawal approved by DTI and which resulted in the eventual withdrawal of nuclear material from safeguards.
2 there are no facilities outside safeguards that manufacture material in such quantities and forms, and defence establishment requirements for these specialist materials have therefore been met by supply from civil organisations.
