Recovering High-Purity Uranyl Nitrate from Simulated Used Nuclear Fuel Dissolver Solutions by Crystallization: Rejecting Technetium
The separation of U from Tc and other problematic fission product elements like Mo and Ru, along with Sr, Zr, Cs, and Nd, has been achieved via the crystallization of uranyl nitrate hexahydrate (UNH). Rejection of technetium as pertechnetate anion (99TcO4–) is an especially important feature of this system, as it otherwise tends to follow U(VI) in extractive separations. I…
