What type of uranium is used for nuclear fission?

Answer 1

Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.

Answer 2

Most reactors in use for power production use uranium dioxide as the fuel material, new fuel being enriched to about 5 percent of U-235 (natural U is about 0.7 percent). The rest is U-238, but during operation plutonium is formed from this U-238 and this contributes to the reactor's power output.

Answer 3

Radioactive metal, natural chemical element, solid, period 7, actinides group, heavy element, unstable

Answer 4

- natural isotopes or artificial isotopes of uranium

- natural uranium, depleted uranium or enriched uranium

- uranium alpha, beta or gamma

etc.

Answer 5

U235 and U238 are important as is the material "depleted uranium".

Answer 6

Uranium is a chemical element, metallic, situated in the actinoids group of the Periodic Table of the elements.
