  1. Irradiated Targets & Mo-99 Internal Transportation in Mo-99 Production Plant at Ezeiza Atomic Centre Fission Mo-99 Production Plant

  2. Transporting the Irradiated Targets from RA3 (Reactor Zone) • Transference of targets to the container (RA-3 hot cell). • Access control to the transference zone. • Radiation field monitoring. Fission Mo-99 Production Plant

  3. Transporting the Irradiated Targets from RA3 (Reactor Zone) • Connection of the device with electronic and magnetic sensor for transferring the container to the transport shielding. • Cold test for the transfer system. • Hot transfer. Fission Mo-99 Production Plant

  4. Transporting the Irradiated Target from RA3 (Moly Plant zone) • Moving out from RA3 zone. • Rails behind hot cells for accurate Hot cell -Transport connection. • La Calhene transference system. • Transference of the container to the hot cell. • Pull out the irradiated targets from the container. Fission Mo-99 Production Plant

  5. Transport (view) • Self propulsion transport. • 23 cm lead shield. • 2000 kg weight. • Total time for targets transporting: 15´. Fission Mo-99 Production Plant

  7. Hot Cell Shield Fission Mo-99 Production Plant

  8. Targets Container • Four targets capacity. • Gasses contention. Fission Mo-99 Production Plant

  9. Transporting the produced radionuclides to the Production Plant • Hermetic plastic flask (first contention). • Metallic container (second contention). • 5 cm depleted Uranium shield (third contention). • The shield is part of a B(U) packaging according to safety series # 6 of IAEA. • Total time for Mo-99 transportation: 5´.
