advantages and disadvantages of breeder reactors

3. 1. Nuclear breeding does not take place in thermal reactors. Light Water Reactors Boiling Water Reactor This section describes boiling water nuclear reactors . A breeder reactor is designed to create more fissile material (nuclear fuel) than it consumes. A Breeder reactor is a type of nuclear reactor that “breeds” or make more fissile material than it uses by using neutrons to convert fertile materiel into fissile material. Depending on the Breeding Ratio of a reactor, it can produce new fuel at a greater or lesser rate. In boiling water nuclear reactors (BWRs), the heat generated by the splitting of uranium atoms is used to boil water within the reactor … The Breeding Ratio represents the number of new fissile atoms created for each fission event. Advantages. Natural uranium consists primarily of U 238 , which does not fission readily, and U 235 , … Both cycles have advantages and disadvantages, especially depending on the kind of reactor used. General Information Boiling water nuclear reactors are a type of light water reactor . The reactor vessel and associated components operate at a substantially lower pressure (about 75 times atmospheric pressure) compared to a PWR (about 158 times atmospheric pressure). Advantages. Liquid metal fast breeder reactors (LMFBRs) have been operated successfully throughout the world. See Also: Types of Nuclear Reactors Advantages of Fast Breeder Reactor : The disadvantages of nuclear fission energy are more perceived than ...The so-called fast-breeder reactor design, which will likely be ... Energy for America: we can achieve energy independence for the 21st century without destroying the environment. Its successor, EBR-II, was used from 1963 to 1994 to test equipment and materials. Nuclear breeding occurs in fast breeder reactors (FBR), where a portion of fertile material gets converted into fissile materials (and thus produce more fuel). Fast reactor fuels are usually 15 – 20% enriched. Fast vs thermal breeder reactors . In the United States, the Experimental Breeder Reactor-I at Idaho Falls was the first power reactor to generate electricity in 1951. In fast breeder reactors, neutron shielding is provided by the use of boron or graphite. In order to protect against gamma radiations, a shield is provided made of lead or concrete or of other materials. Advantages and disadvantages of HWR (or) CANDU type Reactor . The reactor vessel may be built to withstand low pressure, therefore, the cost of the vessel is less. Pressure vessel is subject to significantly less irradiation compared to a PWR, and so does not become as brittle with age. Breeder reactors are possible because of the proportion of uranium isotopes that exist in nature. When a fissile atom fissions from impact by a neutron, it can release multiple neutrons. “Fast breeder reactors are capable of generating more fissile material than consumed,” said Val Aleyaseen, process systems engineer with Candu Energy Inc. in a previous article. The major advantage of this reactor is that the fuel need not be enriched. Some of those neutrons can cause further fission events. 2. Advantages . This can reduce dependency on inadequately available U-235. These reactors are often considered simpler than the more traditional fast-neutron breeders. No control rods are required, therefore, control is much easier than other types. 25.3 The fast breeder reactor. The primary physical advantage of thorium fuel is that it uniquely makes possible a breeder reactor that runs with slow neutrons, otherwise known as a thermal breeder reactor.
