how does a breeder reactor work

This has been considered in the past as generically, a candle reactor, or breed-burn reactor, since it is designed to burn slowly from one end of a core to the other, making the actual fuel as it goes. Power plants everywhere generate electricity by converting mechanical power such as the rotation of a turbine into electrical power. Following work by the DOE's Lawrence Livermore Laboratory, a 1950s design concept resurfaced in 1996 as the travelling wave reactor (TWR). In addition, breeder reactors (which include some types of MSRs) make it possible to use uranium-238 as fuel, which makes up 93.3% of all natural uranium. The LFTR is a breeder design and like any breeder reactor, it can be used to create fuel for nuclear weapons in addition to civilian power. The names can be a bit misleading: Both use steam to power a generator, but the difference is how they create it. The nuclear reactors currently operating in the United States are either boiling water reactors or pressurized water reactors. But there’s a way to make Pu-239 from U-238 in a special fission reactor called a breeder reactor. Besides the U-235 isotope of uranium, the other commonly used fissionable isotope, plutonium-239 (Pu-239), is very rare in nature. A different kind of power plant called a fast-breeder reactor works a different way, producing its own plutonium fuel in a self-sustaining process. 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. Breeder reactors: Making more nuclear stuff. Its chain reaction is much closer to what happens in a nuclear bomb and it doesn't work through a moderator. In a coal-fired steam station, the combustion of coal turns water into steam and the steam in turn drives turbine generators to produce electricity. A boiling water reactor heats up the water in the reactor until it boils into steam and spins the turbine. The pressurized water reactor (PWR) is a type of nuclear reactor used to the generate electricity and propel nuclear submarines and naval vessels. Power plants today rely either on fossil fuels, nuclear fission, or renewable sources like hydro. They make use of light water (ordinary water, as opposed to heavy water) as their coolant and neutron moderator.It is one of three types of light water reactors, with the others being the boiling water reactor and the supercritical water cooled reactor. Given the reactor's closed fuel cycle and generation of plutonium, a fissile fuel, the reactor can also be used as a breeder … Conventional reactors … The water in the core is heated by nuclear … More than 65% of the commercial reactors in the United States are pressurized-water reactors or PWRs. Tritium and deuterium are two isotopes of hydrogen that will be used to fuel the fusion reaction in ITER. While deuterium can be extracted from seawater in virtually boundless quantities, the supply of available tritium is limited, estimated currently at twenty kilos. These reactors pump water into the reactor core under high pressure to prevent the water from boiling. Unlike some nuclear reactors that utilize thermal neutrons, an SFR uses fast neutrons, which are neutrons that have not completely thermalized, to convert U-238 into plutonium. One advantage of using the thorium to breed fissile U-233 is that some U-232 is produced along with U-233.
