Nuclear fuel elements - an overview | ScienceDirect Topics

The spent nuclear fuel element is mechanically the same as fresh fuel and can be handled as an intact fuel element. It is, however, highly radioactive and needs shielding and cooling during handling. The shielding is mainly for gamma and neutron radiation from the fuel.

Nuclear Fuel Elements: Design, Fabrication and Performance is concerned with the design, fabrication, and performance of nuclear fuel elements, with emphasis on fast reactor fuel elements. Topics range from fuel types and the irradiation behavior of fuels to cladding and duct materials, fuel element design and modeling, fuel element performance testing and qualification, and the performance of water reactor fuels.

Nuclear Fuel - Fuel Assembly

Nuclear Fuel. Nuclear fuel is generally any material that can be 'burned' by nuclear fission or fusion to derive nuclear energy. There are many design considerations for the material composition and geometric configuration of the various components comprising a nuclear fuel system. Common nuclear reactors use an enriched uranium and plutonium as a fuel.

Nuclear fuel. These fuels are fissile, and the most common nuclear fuels are the radioactive metals uranium -235 and plutonium -239. All processes involved in obtaining, refining, and using this fuel make up a cycle known as the nuclear fuel cycle . Uranium-235 is used as a fuel in different concentrations.

Nuclear Fuel Cycle

Throw-Away of Used Nuclear Fuel The natural form of uranium in the earth's crust is uranium-308 (U308), which must be enriched by increasing the composition of uranium-235 (U235) in order to be used in a nuclear reactor. The U308 is converted to uranium hexafluoride (UF6), a gas, before it can be enriched.

Spent nuclear fuel. These products can be a result of fission or radioactive decays that take place inside the fuel bundle. Most of the waste is solid, but some of the atoms in the spent fuel are gaseous. These isotopes require more careful containment so that they do not escape and cause radiation damage.

Nuclear Fuel Cycle Overview - World Nuclear Association

The Nuclear Fuel Cycle (Updated March 2017) The nuclear fuel cycle is the series of industrial processes which involve the production of electricity from uranium in nuclear power reactors. Uranium is a relatively common element that is found throughout the world. It is mined in a number of countries and must be processed before it can be used as fuel for a nuclear reactor.

Nuclear Fuel Facts: Uranium | Department of Energy

Most commercial reactor fuel uses low enriched uranium (LEU) enriched to between 3 percent and 5 percent 235 U. Uranium between 3 and 5 percent 235 U is sometimes referred to as "reactor-grade uranium." Highly Enriched Uranium – contains a 235 U concentration greater than 20 percent. Highly enriched uranium (HEU) is used in naval propulsion reactors, nuclear weapons and in some research .

Nuclear Fuel

Nuclear Fuel. Uranium is an abundant metal and is full of energy: One uranium fuel pellet creates as much energy as one ton of coal, 149 gallons of oil or 17,000 cubic feet of natural gas. It does not come out of the ground ready to go into a reactor, though. It is mined and processed to create nuclear fuel.

The fuel that nuclear reactors use to produce nuclear fission is pellets of the element uranium. In a nuclear reactor, atoms of uranium are forced to break apart. As they split, the atoms release tiny particles called fission products. Fission products cause other uranium atoms to split, starting a chain reaction. The energy released from this chain reaction creates heat.
