What is a breeder reactor?

A breeder reactor is designed to generate more fissile material than it consumes, making it an efficient and sustainable option for nuclear fuel production. These reactors utilize a fuel cycle that converts non-fissile isotopes, such as Uranium-238, into fissile materials, typically Plutonium-239. The process enhances the fuel utilization efficiency in nuclear power generation.

The unique feature of breeder reactors lies in their ability to not only sustain nuclear fission but also create additional fuel during that process. This characteristic allows breeder reactors to potentially utilize existing uranium resources more effectively, helping to address long-term energy needs. Hence, the primary goal of a breeder reactor is to extend the fuel supply for nuclear reactors by producing more fissile material, favoring the sustainable nature of the nuclear energy sector.
