Conventional nuclear reactors use uranium-235 as their fuel. However, ... In the liquid-metal, fast-breeder reactor (LMFBR), the target breeding ratio is 1.4 but the results achieved have been about 1.2 . This is based on 2.4 neutrons produced per U-235 fission, with one neutron used to sustain the reaction.

In a breeder reactor, these materials are deliberately provided, either in the fuel or in a breeder blanket surrounding the core, or most commonly in both. Production of fissile material takes place to some extent in the fuel of all current commercial nuclear power reactors. ... 1 Breeding Ratio ... Results from FactBites:

Experiments on a 19-year old UK breeder reactor before it was decommissioned in 1977, and on EBR-2 in the USA in 1986, showed that the metal fuel with liquid sodium cooling system made them less sensitive to coolant failures than the more conventional very high pressure water and steam systems in light water reactors.

Do we need a new kind of reactor? ... The ALMR was to be a "fast" reactor (one in which the chain reaction is maintained by high-energy neutrons) - so called because the energy spectrum of the neutrons is said to be fast. ... A breeder is a reactor that is configured so as to produce more fissile material than it consumes.
