Explanation

uranium naturally exists in nature. Its enrichment degree is natural abundance. natural uranium mainly contains three isotopes, and their contents are respectively 238U99.3%, 235U0.7% and 234U0.006%. All natural uranium isotopes emit a particle. uranium has active chemical properties. There is no pure metal in nature. It exists in the form of oxides, phosphates, sulfates, silicates, carbonates and other minerals. Natural metal uranium is used to manufacture fuel element for graphite water-cooled production reactor and Magnox production power dual-use reactor. The fuel element of CANDU heavy water power reactor uses natural uranium dioxide ceramics pellets. Through uranium isotope separation, natural uranium can produce low, medium and high enriched uranium, which is used for power reactor, fast reactor, research and test reactor and nuclear weapon loading respectively.
