The major advantage of this reactor is that the fuel need not be enriched. Advantages. Depending on the Breeding Ratio of a reactor, it can produce new fuel at a greater or lesser rate. Light Water Reactors Boiling Water Reactor This section describes boiling water nuclear reactors . Nuclear breeding does not take place in thermal reactors. 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. The Breeding Ratio represents the number of new fissile atoms created for each fission event. 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. When a fissile atom fissions from impact by a neutron, it can release multiple neutrons. 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 . These reactors are often considered simpler than the more traditional fast-neutron breeders. Fast reactor fuels are usually 15 – 20% enriched. 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). A breeder reactor is designed to create more fissile material (nuclear fuel) than it consumes. 3. Pressure vessel is subject to significantly less irradiation compared to a PWR, and so does not become as brittle with age. 25.3 The fast breeder reactor. Nuclear breeding occurs in fast breeder reactors (FBR), where a portion of fertile material gets converted into fissile materials (and thus produce more fuel). General Information Boiling water nuclear reactors are a type of light water reactor . See Also: Types of Nuclear Reactors Advantages of Fast Breeder Reactor : The reactor vessel may be built to withstand low pressure, therefore, the cost of the vessel is less. Its successor, EBR-II, was used from 1963 to 1994 to test equipment and materials. In the United States, the Experimental Breeder Reactor-I at Idaho Falls was the first power reactor to generate electricity in 1951. “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. Some of those neutrons can cause further fission events. In fast breeder reactors, neutron shielding is provided by the use of boron or graphite. This can reduce dependency on inadequately available U-235. 1. Liquid metal fast breeder reactors (LMFBRs) have been operated successfully throughout the world. Breeder reactors are possible because of the proportion of uranium isotopes that exist in nature. Fast vs thermal breeder reactors . Advantages . Both cycles have advantages and disadvantages, especially depending on the kind of reactor used. Advantages. No control rods are required, therefore, control is much easier than other types.
