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).
Uranium is used as nuclear fuel in nuclear power plants because the fission of uranium atom release a formidable quantity of energy.
It can produce low grade plutonium that need be extracted from the used nuclear fuel through used fuel reprocessing. However, power reactors are subject to the international nuclear safeguards to prevent its misuse.
Nuclear fission
Yes
Most nuclear fuel for nuclear reactors in power plants is enriched uranium, though there are some plants that use "regular" uranium, like the plants using heavy water. There are also plants that use plutonium.Research and development is being done on nuclear plants using thorium as fuel.Surf on over to the Wikipedia articles to mine more data. You'll find links to them below.
NO!
That is the main use, to fuel nuclear power plants
Uranium
Uranium is used as nuclear fuel in nuclear power plants because the fission of uranium atom release a formidable quantity of energy.
Yes, uranium is the most important nuclear fuel.
Yes, plutonium is a very important nuclear fuel.
No, chromium has no fissile properties for use as fuel
B. Uranium
No, Enriched Uranium-235 is used in a nuclear reactor as the fuel in the fuel rods and boron is used in the control rods.
It can produce low grade plutonium that need be extracted from the used nuclear fuel through used fuel reprocessing. However, power reactors are subject to the international nuclear safeguards to prevent its misuse.
Yes, plutonium is a very important fuel for nuclear reactors.
No. Nuclear power plants use a uranium to provide the heat to generate electricity from. By splitting the nuclei of uranium atoms (called nuclear fission), energy is released, which will be used for electricity generation. Uranium is a radioactive metal, not a fossil fuel.
