U 3 O 8 is the uranium product which is sold. Uranium enrichment is a process that is necessary to create an effective nuclear fuel out of mined uranium by increasing the percentage of uranium-235 which undergoes fission with thermal neutrons.Although many reactors require enriched uranium fuel, the Canadian-designed CANDU, the British Magnox reactor and the proposed Molten salt reactor can use natural uranium as their fuel. Russian enrichment plants have treated 10-15,000 tonnes per year of DU assaying over 0.3% U-235, stripping it down to 0.1% and producing a few thousand tonnes per year of natural uranium equivalent. Q18. 38. All uranium isotopes present in natural uranium are radioactive and fissionable, and 235 U is fissile (will support a neutron-mediated chain reaction). The byproduct of enrichment, called depleted uranium or DU, contains less than one third as … 4. B. The energy content of the U-235 isotope in natural uranium is therefore 0.0072×8.3×10 16 J t −1 ∼5.7×10 14 J t −1, and the energy in proven uranium reserves and ultimately recoverable resources is ∼61 and 300 TW/year, respectively (1 TW/year=31.5 EJ). A quantity of HEU can be described in terms of either the total mass of all the uranium isotopes, kg U, or as the mass of the fissile isotope uranium … Identified resources in situ to US$ 130/kg U are 8.122 Mt, and to US$ 260/kg U, 10.653 Mt. IF YOU THINK THAT ABOVE POSTED MCQ IS WRONG. The PWR nuclear fuel is enriched uranium dioxide (UO2) that contains about 3 wt% of fissionable 235 U, or mixed uranium-plutonium oxide (MOX) in pellet form. Most reactors require uranium to be enriched from 0.7% to higher concentrations. This new grade is being used to replace natural uranium(NU) fuel in some heavy water reactors like the CANDU.
