Successor to the Magnox reactors and unique to the UK. AGRs use enriched uranium clad stainless steel cans and also have a graphite moderator and use pressurised CO2 as the coolant. These allow the AGRs to operate at a higher temperature than the Magnox reactor. The AGR REactor is encased in a steel-lined pre-stressed concrete pressure vessel several metres thick which acts as the biological shield, with the boilers inside. The coolant conveys heat from the reactor to the boilers which, in turn, heats water in an isolated steam circuit which is then used to turn the turbines, just as in coal, oil or gas-fired stations.
