Operation:- Carbon dioxide or Helium is the gas used for transferring the heat produced form the reactor core to the Heat exchanger. The gas is pumped through the reactor core at high pressure. In heat exchanger steam is generated at high temperature and high pressure. Cooled gas is drawn from the Heat exchanger and passed in reactor core and cycle is repeated.
Fuel used in Uranium. Moderator used is Graphite. Coolant used is CO2/Helium. Temperature obtain is 5650C. The AGR was designed to have a high thermal efficiency 40 %. Steam pressure is 162 Kg/cm2
