Fast Breeder Reactor (FBR)

A Fast Breeder Reactor (FBR) is an advanced type of nuclear reactor that utilizes fast neutrons to convert fertile isotopes, such as uranium-238, into fissile isotopes like plutonium-239. Unlike traditional thermal reactors, FBRs do not require a neutron moderator to slow down neutrons, allowing for a higher efficiency of fuel utilization. This characteristic enables FBRs to generate more fissile material than they consume, effectively "breeding" fuel and leading to a more sustainable nuclear energy cycle.

Fast Breeder Reactors are designed to operate with a closed fuel cycle, meaning that the spent fuel can be reprocessed and reused. This contributes significantly to reducing nuclear waste and optimizing natural resource use. By enhancing the efficiency of fuel consumption and mitigating the environmental impact, FBRs represent an important advancement in sustainable nuclear technology.
