There are two radioisotopes that serve as fuel for a nuclear reactor. The first is uranium-235, which is a constituent of natural uranium. U-235 is a "fissile" isotope -- i.e., the one that splits when it absorbs a neutron of a certain energy. When a reactor starts up with a fresh load of fuel, all of the early activity involves U-235.

This splitting, or fissioning, of U-235 atoms releases energy in the form of heat. The production of heat is the whole purpose of certain types of nuclear reactors. This heat converts water into steam to turn a turbine generator and make electricity.

Fission also releases neutrons. These neutrons sometimes are absorbed into another uranium isotope, uranium-238, another constituent of natural uranium which is also present in nuclear fuel. When U-238 absorbs a neutron, it eventually becomes plutonium-239. Pu-239 is another fissile isotope, i.e., it also fissions when struck by a neutron of a certain energy.

So the two isotopes that are used as fuel for a nuclear reactor are uranium-235 and plutonium-239. The former gets the reactor going; the latter is made inside the reactor.

Some nuclear reactors are designed solely to produce neutrons. These are research reactors. Neutron interactions with other materials are of great interest to a great many scientists and engineers.

What is the name of the fuel used in the nuclear reactor?

The fuel used in a nuclear reactor is typically uranium. Specifically, the most common type of uranium used is uranium-235, which undergoes nuclear fission to produce energy in the reactor.


What is a used fuel in nuclear power plants?

The used fuel in a nuclear power plant is the nuclear fuel being discharged from the nuclear reactor after being irradiated during reactor operation. It is usually composed of trans-uranium heavy elements, a wide variety of fission products (that resulted from the nuclear fission processes in the nuclear reactor) and products of radioactive decay (produced before and after fuel discharge from the nuclear reactor).

In what part of a nuclear reactor is the fuel is located?

The fuel in a nuclear reactor is located in the fuel rods, which are typically made of materials such as enriched uranium or plutonium. These fuel rods are where the nuclear fission reaction takes place, producing heat that is used to generate electricity.


What are fuel cells in a neclear reactor?

Fuel cells in a nuclear reactor are the structural components where nuclear fission reactions occur, generating heat. This heat is used to produce steam, which drives turbines to generate electricity. The fuel cells contain the nuclear fuel (such as uranium) and control rods to regulate the nuclear reactions.

What is a fuel rod in a nuclear reactor?

A fuel rod is a long, slender tube that contains the fuel pellets (usually uranium or plutonium) used in a nuclear reactor. These fuel rods generate heat through nuclear fission reactions, which is then used to produce electricity. Multiple fuel rods are assembled together in a fuel assembly to power the reactor.
