Notes

  1. The tabulated information covers advance notifications of withdrawal approved by ONR Safeguards and which resulted in the withdrawal of nuclear material from safeguards.
  2. There are no facilities outside safeguards that have material in such quantities and forms, and defence establishment requirements for these specialist materials have therefore been met by supply from civil organisations.
  3. The advance notifications of withdrawal for depleted uranium shielded containers were for temporary withdrawals, the containers being used during the replacement of spent radioactive sources at UK defence establishments.
