Webbreeder programs begun in the Nixon era. The cost of development and con-struction is another problem in the breeder reactor program. Currently, the capital cost of the breeder is significantly higher than that of the light-water reac-tor. Constructing a 1000-MWe light-water reactor would cost about $1.7 billion, while a fast breeder reactor WebFigure 2. Cut-Away View of a Pool-Type Fast Breeder Reactor (Phenix). 3.

Breeder reactor - Wikipedia
WebSEFOR (Southwest Experimental Fast Oxide Reactor) was an experimental fast breeder reactor located in Cove Creek Township, Washington County, near Strickler, in northwest Arkansas (20 miles southwest of Fayetteville, Arkansas).The site consisted of a 20-Megawatt (thermal), Sodium-Cooled Test Reactor, a Shop Building, an Operations … WebThe 500 MWe Prototype Fast Breeder Reactor (PFBR) started construction in 2004 at Kalpakkam near Madras. It was expected to start up about the end of 2010 and produce power in 2011, but this schedule was delayed significantly. In 2014, 1750 tonnes of sodium coolant was delivered. A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. 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 … See more Breeder reactors could, in principle, extract almost all of the energy contained in uranium or thorium, decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors, … See more One measure of a reactor's performance is the "conversion ratio," defined as the ratio of new fissile atoms produced to fissile atoms consumed. … See more Fission of the nuclear fuel in any reactor unavoidably produces neutron-absorbing fission products. One must reprocess the fertile material from a breeder reactor to remove those See more There are several concepts for breeder reactors; the two main ones are: • Reactors with a fast neutron spectrum are called fast breeder … See more Many types of breeder reactor are possible: A 'breeder' is simply a reactor designed for very high neutron … See more Nuclear waste became a greater concern by the 1990s. Breeding fuel cycles attracted renewed interest because of their potential to reduce actinide wastes, particularly … See more Like many aspects of nuclear power, fast breeder reactors have been subject to much controversy over the years. In 2010 the International Panel on Fissile Materials said "After six decades and the expenditure of the equivalent of tens of billions of dollars, … See more huahui 공장
