Liquid-Metal Fast-Breeder Reactor . Volume 4. LMFBR Basics •A fast breeder reactor can convert Uranium-238 into Plutonium-239 at a rate faster than it consumes its fuel (mixture of U-235 plus Pu-239) •By repeated recycling of the fuel, it should be realistically possible to exploit 50% of the fuel value of the uranium feed A liquid metal fast breeder (LMFBR) is a type of nuclear reactor which is capable of producing more so-called fissile material than it takes in. An advantage of this type of reactor is that the liquid metal has great heat transfer properties so that the reactor can be operated at much lower pressures and higher temperatures. In the Liquid-Metal Fast-Breeder Reactor the fission reaction produces heat to run the turbine while at the same time breeding plutonium fuel for the reactor. Natural uranium is made up of Liquid metal cooled reactors — Design and construction. location London . Its successor, EBR-II, was used from 1963–94 to test equipment and materials. First Published 1974 . There is an adequate supply of plutonium in the world for all current and projected needs; there is no market for any excess that can be produced in a reactor. The Russians started with 2, 5, and 10 MW prototypes Sodium becomes more radioactive than water when used as a coolant, again complicating routine maintenance. The metals which can accomplish this are sodium and lithium, with sodium being the most abundant and most commonly used. Liquid metal fast breeder reactors (LMFBRs) have been operated successfully throughout the world. BN- 350 and BN-600 in USSR and Superphénix in France were this type of reactors. (1981). It was one of only two fast reactors ever built in the UK, both at Dounreay.

It does not object breeding but a stable operation without fissile makeup under practical contingencies. The uranium situation provided an incentive to seek ways to increase the fuel supply by developing reactors that could make better use of the material that was available. Theconstruction of the fast breeder requires a higher enrichment of U-235 than a light-waterreactor, typically 15 to 30%. A fast breeder reactor is one which utilises fast neutrons for fission reaction. Sodium, the most commonly used metal, reacts explosively in air and water. The situation was considered even more critical since the first reactors depended on U-235 for fuel and that isotope only represents 0.7% of natural uranium. The MSRE operated from 1965 to 1969, when it was shut down under the orders of Milton Shaw of the Atomic Energy Commission so as to free up additional funding for the liquid-metal fast breeder reactor (LMFBR) program. All current fast neutron reactor designs use liquid metal as the primary coolant, to transfer heat from the core to steam used to power the electricity generating turbines. Gonyeau, P.E.. Using U-238 as fuel could increase the energy value of the world’s uranium stocks by a factor of 100 or more. Under current market conditions, a successful breeder concept will be one that maximizes the owner’s return on investment in the atomic plant as an electrical power production machine. LMFBR abbreviation stands for Liquid-Metal Fast-Breeder Reactor. Conventional reactors use … An advantage of this type of reactor is that the liquid What does LMFBR stand for? Sometimes these are called breeder, fast, or fast The Virtual Nuclear 1. This supplement describes a number of modifications to the Liquid Metal Fuel Reactor Experiment (LMFRE), including (1) engineering design changes to achieve economies in the original reference design, and (2) a revised cost estimate that reapportions the various construction, research and development, and operating costs in accordance with procedures established by the Atomic Energy Commission. If more neutrons are produced by each fission, there will be more neutrons available to convert U-238. Metals have high heat transfer coefficients, allowing high power density cores. High power density cores could produce more plutonium with a smaller initial investment, thus allowing a higher rate of return when the plutonium was sold to the government. For each fissile atom that is consumed in fission, it is possible to produce at least one new atom of plutonium. Create free account to access unlimited books, fast download and ads free!
