Fast Breeder Reactor (FBR)
Fast Breeder Reactors (FBRs) use plutonium-239 as fuel and have the unique capability of converting uranium-238 into plutonium-239. This process is known as breeding, where fissile material is produced from non-fissile material.
How FBR Works
- FBRs use fast neutrons to sustain the nuclear chain reaction, unlike thermal reactors that use slow neutrons.
- Plutonium-239 is used as the primary fuel in FBRs, which is capable of sustaining the chain reaction efficiently.
- In the core of the reactor, fast neutrons convert uranium-238 into plutonium-239 through a process called breeding.
- The bred plutonium-239 can then be used as fuel in the reactor, creating a sustainable cycle of nuclear fuel production.
Advantages of FBRs
- FBRs have a higher fuel efficiency compared to traditional reactors, as they can utilize both fissile and fertile materials for energy production.
- These reactors produce less long-lived radioactive waste compared to other reactor types.
- FBR technology has the potential to help in closing the nuclear fuel cycle and reducing the amount of nuclear waste generated.
In conclusion, Fast Breeder Reactors play a crucial role in the future of nuclear energy production by utilizing plutonium-239 as fuel and converting uranium-238 into fissile material for sustained nuclear reactions.
