Light Water Reactors (LWRs) are fuelled by Low Enriched Uranium

  • A boiling water reactor (BWR) is a type of Light water nuclear reactor used for the generation of electrical power.
  • Pressurized water reactor (PWR) is also a type of light water nuclear reactor.
  • VVER (Water-Water reactor) is a type of PWR
  • The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine.
  • In a PWR, the reactor core heats water, which does not boil. This hot water then exchanges heat with a lower pressure water system, which turns to steam and drives the turbine.
  • A boiling water reactor (BWR) uses demineralized water as a coolant and neutron moderator. Heat is produced by nuclear fission in the reactor core, and this causes the cooling water to boil, producing steam. The steam is directly used to drive a turbine, after which it is cooled in a condenser and converted back to liquid water.
  • In comparison, there is no significant boiling allowed in a pressurized water reactor (PWR) because of the high pressure maintained

PHWR – Pressurised Heavy Water Reacto

The Pressurised Heavy Water Reactors (PHWRs) are fuelled by Natural Uranium

FBR- Fast Breeder Reactor

Prototype Fast Breeder Reactor (PFBR) being implemented by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI) is fuelled by Mixed Oxide (MoX) Fuel.
