For production of electricity, about 19 percent
For NBL 0,99975 % uranium: 1 230 US $ for 4 grams.
Uranium enriched with isotope 235 to approx 4 percent (natural U is 0.7 percent 235)
Uranium is the major component of the nuclear fuel in the nuclear energetic reactors. Also United States use uranium for weapons.
It is possible to obtain very beutiful objects from uranium glass (a glass with some percent of uranium oxide).
The main fuel isotope is uranium-235. This isotope is the fissile part of natural uranium, with natural uranium being mostly U-238. Uranium is usually enriched before use to increase the concentration of U-235. Plutonium-239 is also usable, and in some countries a mixture of uranium and plutonium (MOX) is used.

The uranium oxide U3O8 contain 84,8 % uranium.
Uranium 235 is 0.7 percent of natural uranium and is fissile

Probably 10 %.
Natural uranium has about 0.7 percent U235, this has to be increased to about 4 percent for use in natural water moderated reactors. The obtaining of uranium from mining and refining is described in the document linked below
Uranium tetrafluoride - UF4
Most reactors use uranium fuel enriched slightly to about 3-4 percent U-235, in the form of uranium dioxide UO2. Some older reactors used metallic natural uranium, while some other reactors use plutonium or a plutonium-uranium mix as fuel.
UF6 is the answers.Hope it helps.
approx. 70 tonnes.
