Neutron crosssection for fission. Fast spectrum vs. Thermal spectrum Source: org Nuclear Power> Nuclear Power Plant> Types of Reactors> Fast Neutron Reactor. A fast neutron reactor is a nuclear reactor in which the fission chain reaction is sustained by fast neutrons.That means the neutron moderator (slowing down) in such reactors is undesirable.
Jun 27, 2017 · The Beloyarsk Nuclear Plant is the only commercially operating fast breeder reactor in the world. Developed over more than 20 years, it started producing power since October 2016.
The next chapter deals with the physics of fast reactors and considers calculation methods, flux distribution, breeding, control rods, shielding, and reactivity coefficients. The chemistry of fast reactor fuels is also considered, along with the engineering of the core of a powerproducing fast reactor and of coolant circuits and steam plants.

The Prototype Fast Breeder Reactor (PFBR) is a 500 MWe fast breeder nuclear reactor presently being constructed at the Madras Atomic Power Station in Kalpakkam, India. The Indira Gandhi Centre for Atomic Research (IGCAR) is responsible for the design of this reactor.
Nuclear reactor Nuclear reactor Thermal, intermediate, and fast reactors: Reactors are conveniently classified according to the typical energies of the neutrons that cause fission. Neutrons emanating in fission are very energetic their average energy is around two million electron volts (MeV), nearly 80 million times the energy of atoms in ordinary matter at room temperature.
The fastreactor system with pyroprocessing is versatile. It could be a net consumer or net producer of plutonium, or it could be run in a breakeven mode. Operated as a net producer, the system could provide startup materials for other fastreactor power plants. As a net consumer, it could use up excess plutonium and weapons materials.
