Another alternative to fast breeders is thermal breeder reactors that use uranium-233 bred from thorium as fission fuel in the thorium fuel cycle.

China also initiated a research and development project in thorium molten-salt thermal breeder reactor technology ( Liquid fluoride thorium reactor ), formally announced at the Chinese Academy of Sciences ( CAS ) annual conference in January 2011.

Finally, the ratio of neutrons released per neutron absorbed ( ? ) in is greater than two over a wide range of energies, including the thermal spectrum; as a result, thorium-based fuels can be the basis for a thermal breeder reactor.

The approach introduced by Gruen was fruitful not only in helping to provide a fundamental understanding of fused salt chemistry, but also in its implications for the eventual development of a homogeneous thermal breeder reactor based on fused salt solutions containing the relatively plentiful element thorium.
