G-IV: fourth generation reactors

Most all of the present nuclear power plants use thermal neutron induced fission of uranium and plutonium (U-Pu fuel cycle). Fast neutrons produced in fission are slowed down in in water which is also the coolant of the reactor’s core. They are mainly Pressurized Water Reactors (PWR), or Boiling Water Reactors (BWR). They are from the so called second generation of nuclear power plants. Some reactors of third generation like the EPR are still under construction. They are pressurized water (...)
