advantages of fast breeder reactor

The second type of breeder reactor is a thermal breeder reactor, which uses an initial fuel charge of enriched uranium, thereafter using only thorium. The fertile material is uranium-238, the major isotope in natural uranium. As a matter of fact more fissile material could be produced than would be consumed by it (fast breeder reactor). Fuel consumption is very less. Advantages of nuclear power plant 1. A small core is sufficient since it gives high power density as compared to other reactors. The absorption of the neutron is slow. In order to protect against gamma radiations, a shield is provided made of lead or concrete or of other materials. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232 that is loaded into the reactor along with fissile fuel. Fast breeder reactor (FBR) – Fast Breeder Reactor – Advantages and Disadvantages. Secondary fissile material by breeding is obtained. A Fast Breeder Reactor (FBR) is a nuclear reactor that uses fast neutron to generate more nuclear fuels than they consume while generating power, dramatically enhancing the efficiency of the use of resources. ◆ A breeder reactor creates 30% more fuel than it consumes. A breeder reactor is designed to create more fissile material (nuclear fuel) than it consumes. Breeders were at first found attractive because they made more complete use of uranium fuel than light water reactors, but interest declined after the 1960s as more uranium reserves w… Fast reactors are a class of advanced nuclear reactors that have some key advantages over traditional reactors in safety, sustainability, and waste. Fast breeder reactors which use uranium-238 as fuel and thermal breeder reactors which use thorium-232 as fuel. Even 3 g of uranium, on undergoing fission, can release ten times the energy produced by a ton of coal. Fast Breeder Reactor . Breeder reactor The reactors which are designed so that breeding will take place is known as breeder reactor. This man-made fuel Pu-239 can be used for further fission. It is very difficult to explain the possible advantages and disadvantages. Based on this experience and also taking into account the international experience, design of a 500MWe Prototype Fast Breeder Reactor (PFBR) has been done. This special type of reactor is designed to extend the nuclear fuel supply for electric power generation. Fast Breeder Reactor (FBR) Power Plant | Advantages and Disadvantages, Post Comments In fast reactors, the chain reaction is sustained by fast neutrons that have energy of 1 – 10MeV and velocity of around 50,000km/s. 3. Apart from a fast-breeder reactor, the main alternative is to blend the plutonium with other fuel to create a mixed-oxide fuel (mox) that will burn in conventional nuclear power plants. Since plutonium does not exist naturally, it must be produced initially in a uranium fuel cycle. A breeder reactor is essentially a particular configuration of afast reactor. ◆ It can generate much more energy than traditional coal power plants.

Thorium Reactors – Advantages and Disadvantages. 2. The U.S. Department of Energy's Office of Scientific and Technical Information As Argonne explains it, when an atom in a nuclear reactor “fissions”—or splits into several smaller fragments—neutrons are released at high energy (fast speeds). Thorium-uranium fuel cycle. Some fast breeder reactors can generate up to 30 percent more fuel than they use. Figure shows a fast breeder reactor system. 2. The advantage with a breeder reactor is that it generates more fissile material than it consumes. One advantage is that all the neutrons from the uranium and plutonium used in the reaction are used to generate more fissile material.
