NettetSome 10.5 tonnes of plutonium and 1000 tonnes of reprocessed uranium (RepU) are recovered each year from the 1050 tonnes treated each year. The plutonium is immediately shipped to the 195 t/yr Melox plant near Marcoule for prompt fabrication into about 100 tonnes of MOX fuel. NettetUranium is a heavy fissile material that is necessary for nuclear fission. Despite being a prevalent metal on earth, uranium is a nonrenewable resource. An isotope of uranium, uranium-235, is the only one used as fuel in nuclear power plants. Its readily split-apart atoms are the reason for this.

NettetAround 99.284% of natural uranium's mass is uranium-238, which has a half-life of 1.41×1017seconds(4.468×109years, or 4.468 billion years).[1] Due to its natural abundance and half-life relative to other radioactive elements, 238U produces ~40% of the radioactive heat produced within the Earth.[2] Nettet61 rader · Uranium is a widely distributed metal with large low-grade deposits that are not currently considered profitable.
