Batch Furnaces

Home > Technologies > HTR fuel carbonizing furnaces

ALD France has developed horizontal batch furnaces for the sintering and annealing of nuclear fuel as well as for the conversion of Uranium Oxide UO2 into Uranium Carbide UC and Uranium Nitride UN.

This furnaces type closes the gap between laboratory size manufacturing and large-scale manufacturing with GWSmo pusher furnaces.

Key figures

  • Capacity and treatment space adjustable to customer requirements
  • Temperature: up to 1900 °C
  • Operational pressure: 1 mbar
    up to 1 bar
  • Process Gas: Ar, H2, Ar/H2 N2, N2 /H2
  • Gas Flow: 5 m³/h to 50 m³/h
