1. Uranium must be refined to obtain "nuclear grade" uranium.
2. The enrichment in the isotope 235U depends on the type of the nuclear reactor; some reactors (as CANDU) work with natural uranium.
Depending on: - the type of the nuclear reactor - the electrical power of the nuclear reactor - the type of the nuclear fuel - the enrichment of uranium - the estimated burnup of the nuclear fuel etc.
Uranium is the radioactive material element used in nuclear reactors, including the Fukushima Daiichi plant in Japan. Uranium undergoes fission reactions, releasing energy that is used to generate electricity.
Natural uranium
in the nucleus
Typically 3% uranium-235, 97% uranium-238.
The majority of commercial nuclear power reactors use uranium (natural or enriched) as nuclear fuel.
The new fuel is uranium dioxide, enriched to about 4 percent U-235
Normally Uranium enriched to about 4 percent U-235, in the form UO2
Fukushima Daiichi uses Uranium-235, at a slightly enriched ratio of about 5%.
The Chernobyl nuclear plant used enriched uranium as fuel in its reactor. The accident at the plant resulted in a nuclear chain reaction, leading to a catastrophic explosion and release of radioactive materials.

U-235 is the enriched form of U-238 which is used in fission reactors as the fuel rods.
A nuclear power plant does use uranium as fuel It "burns" it in the nuclear sense not the chemical sense
Nuclear fuel is generated in nuclear reactors, where a process called nuclear fission converts uranium isotopes into energy. This energy is harnessed to generate electricity in power plants. The fuel is typically produced in specialized facilities where uranium is enriched and fabricated into fuel rods before being loaded into reactors.
Either yellow uranium oxide (yellowcake) or metallic uranium in most reactors. In moderated thermal neutron reactors the uranium is usually enriched to 3% to 5% uranium-235 isotope, in unmoderated fast neutron reactors the uranium is enriched to 20% to 95% uranium-235 isotope. This uranium comes from mines (similar to coal or iron ore mines). What is mined is usually black uranium oxide ore. This ore is processed to make unenriched yellowcake (0.7% uranium-235) and shipped to the enrichment plant. Most enrichment plants process the yellowcake to make uranium hexafloride then run that through their system, producing both enriched uranium (product) and depleted uranium (waste). The enriched uranium hexafloride is then processed back to yellowcake and shipped to a finishing plant that uses it to make the required fuel assemblies.
Nuclear power plant fuel, also known as nuclear fuel, is made by enriching naturally occurring uranium to increase the concentration of the fissile isotope U-235. This enriched uranium is then fabricated into ceramic pellets, usually made of uranium dioxide, which are stacked into fuel rods. These fuel rods are then assembled into fuel assemblies that are used in the nuclear reactor core for power generation.
