• Fission product — Fission products are the atomic fragments left after a large nucleus fissions. Typically, a large nucleus like Uranium fissions by splitting into two smaller nuclei, along with a few neutrons and a large release of energy in the form of heat… …   Wikipedia

• Fuel temperature coefficient of reactivity — is the change in reactivity of the nuclear fuel per degree change in the fuel temperature. The coefficient quantifies the amount of neutrons that the nuclear fuel (uranium 238) absorbs from the fission process as the fuel temperature increases.… …   Wikipedia

• Fuel fleas — are microscopic hot particles of new or spent nuclear fuel. While small, they tend to be intensely radioactive. The fuel particles, the size about 10 micrometers, are a strong source of beta and gamma radiation and a weaker source of alpha… …   Wikipedia

• fuel reprocessing — noun The processing of nuclear fuel after use to remove fission products, etc and to recover fissile and fertile materials for further use (also reprocessing) • • • Main Entry: ↑fuel …   Useful english dictionary

• Fission products (by element) — On this page, a discussion of each of the main elements in the fission product mixture from the nuclear fission of an actinide such as uranium or plutonium is set out by element. Krypton 83 86 Krypton 85 is formed by the fission process witha… …   Wikipedia

• Fission-fragment rocket — The fission fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, in theory, produce very high specific impulses while… …   Wikipedia

• Fuel — For other uses, see Fuel (disambiguation). Wood was one of the first fuels used by humans and is still the primary energy source in much of the world.[citation needed] Fuel is any material that stores …   Wikipedia

• Fuel element failure — A fuel element failure is a rupture in a nuclear reactor s fuel cladding that allows the nuclear fuel or fission products in the form of dissolved radioisotopes or hot particles to enter the reactor coolant or storage water.The de facto standard… …   Wikipedia

• Fission fragment reactor — Similar to how the fission fragment rocket produces thrust, a fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing …   Wikipedia

• Fission sail — The fission sail is a type of spacecraft propulsion proposed by Robert Forward that uses fission fragments to propel a large solar sail like craft. It is similar in concept to the fission fragment rocket in that the fission by products are… …   Wikipedia
