Nuclear Reactor | Encyclopedia.com

A breeder reactor is a nuclear reactor that generates new fissile or fissionable material at a greater rate than it consumes such material. These reactors were initially (1940s and 1960s) considered appealing due to their superior fuel economy; a normal reactor is able to consume less than 1% of the natural uranium that begins the fuel cycle, whereas a breeder can utilize a much greater ...

A Medley of Potpourri: Liquid fluoride thorium reactor

The thorium fuel cycle is the path that thorium transmutes through from fertile source fuel to uranium fuel ready for fission.Th-232 absorbs a neutron, transmuting it into Th-233. Th-233 beta decays to Pa-233 and finally undergoes a second beta minus decay to become U-233. This is the one way of turning natural and abundant Th-232 into something fissionable.
