Advanced Gas-cooled Reactor

The Advanced Gas -cooled Reactor (AGR ) is a type of nuclear reactor from the group of gas-cooled reactors. He is a descendant of the Magnox reactors in the 1950s developed in Great Britain and used commercially. In contrast to the Magnox reactors use low-enriched uranium dioxide instead he uranium metal as fuel. This allows higher power densities and higher coolant outlet temperatures. The first British AGR ( Hunterston ) was commissioned in 1976.

The essential features of an EGR are:

  • Coolant: carbon dioxide gas ( CO2)
  • Moderator: graphite
  • Fuel: uranium dioxide ( UO2)
  • Enrichment degree: 2.5 %
  • The fuel cladding material: stainless steel
  • Specific uranium inventory: about 170 tons of uranium per GW of electric power
  • Pressure: 40 bar
  • Temperature: 650 ° C

Use

Locations of EGR are only in the United Kingdom: Dungeness B, Hartlepool, Heysham, Hinkley Point B, Hunterston B, Torness and Windscale.
