For production of electricity, about 19 percent
For NBL 0,99975 % uranium: 1 230 US $ for 4 grams.
Most nuclear power plants use enriched uranium as a nuclear fuel. Uranium-235 is the most commonly used isotope for nuclear fission reactions in nuclear power plants, where the uranium atoms split, releasing energy.
Uranium is an element, it does not 'use' any products.
Candu reactors have traditionally used natural uranium, which contains 0.7 percent U-235, which is the fissile isotope that produces all the nuclear fission energy. Proposals have been made that Candus could use fuel that has been discharged from light water reactors and might still contain about 0.9 percent U-235, or could even use fuel made from depleted uranium (mostly U-238) together with fissile plutonium available from dismantled nuclear weapons, but I don't think such proposals have reached the stage of implementation. For one thing, Canada doesn't have any nuclear weapons, so it would require some fuel manufacture to be set up in the US to make this fuel, or to utilise US spent fuel. There is plenty of this in US storage but no route for using it to make Candu fuel, which is of different dimensions and assembly details. However this might conceivably be done in the future.
Uranium contributes to the economy of the US primarily through its use in nuclear power generation, which provides a significant portion of the country's electricity. This creates jobs in the nuclear energy sector, contributes to energy security, and reduces greenhouse gas emissions. Additionally, uranium mining and processing operations also support local economies in regions where these activities take place.

The uranium oxide U3O8 contain 84,8 % uranium.
Probably 10 %.
approx. 70 tonnes.
United States buy from other countries an important percentage of the necessary uranium.
Uranium 235 is 0.7 percent of natural uranium and is fissile
Depleted uranium is approx. 60% less radioactive than an equivalent mass of natural uranium.
Percent per mass example: uranium concentration in granite is approh. 4 mg/kg. Percent per volume: uranium concentration in ocean water is approx. 4 micrograms/L.
Uranium is a chemical element, not a compound.
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
