Innovative process flowsheet for the recovery of Uranium …

Natural uranium (~99.3% U + ~ 0.7 % U) is the basic raw material for nuclear fuel in Pressurized Heavy Water Reactors (PHWR). The energy in the reactor is derived from the 'fission' of U, the only 'fissile' isotope in nature. These reactors also transmute the more abundant U to man–made fissile isotope Pu, which could be subjected to multiple …

There are three natural isotopes of uranium — uranium-234 (U-234), uranium-235 (U-235) and uranium-238 (U-238). U-238 is the most common one, accounting for around 99 per cent of natural uranium found on earth. Most nuclear reactors use fuels containing U-235, however, natural uranium typically contains only 0.72 per …
