  Note :

  The fuel, natural uranium dioxide pellets, is contained in zirconium alloy (zircaloy) cans and these are enclosed as bundles in individual pressure tubes, also made of zircaloy. These tubes conduct the coolant and act as a pressure vessel rather than the whole reactor core being enclosed in a pressure vessel. A pressure of 85 atmospheres is used. The hot, heavy water emerges from the pressure tubes at the ends of the calandria and feeds into larger diameter header pipes which carry it to steam generators. Heat output is around 1 750 MW giving about 508 MeV with an efficiency of just under 30 per cent. Using heavy water a higher natural uranium fuel burn-up is possible than with graphite-moderated reactors. A proportion of the energy output is produced by the fission of plutonium formed in the reactor.
