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.
The fuel rods are of uranium dioxide, with the uranium enriched to about 5% U-235
In a nuclear fission reactor power plant
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
The fuel rods are of uranium dioxide, with the uranium enriched to about 5% 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%.
Enriched uranium is the main fuel. Due to the extension of the article, a link below was created to access Wikipedia with full information about Nuclear Power Plant.
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
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.
It is a nuclear change because there is a change in the nuclear structure of Uranium.
Uranium is used as nuclear fuel.
