Uranium - Wikipedia

Uranium-234, which is a member of the uranium series (the decay chain of uranium-238), decays to lead-206 through a series of relatively short-lived isotopes. Uranium-233 is made from thorium-232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.

Uranium extraction: Fuel from seawater | Nature …

17-2-2017 · There are over four billion tonnes of uranium in the oceans that could be harvested for nuclear fuel, but current capture methods have limited performance and reusability. Now, an electrochemical method using modified carbon electrodes is shown to be promising for the extraction of uranium from seawater.

Uranium Solvent Extraction - BASF

extraction (SX) reagent for the recovery and concentration of uranium. Prior to 1957, ion exchange (IX) was the accepted route for the recovery of uranium from acid leach solutions. With Alamine® 336 vastly improving the solvent extraction process, BASF reagents now offered the advantages of reduced costs, reduced use of

Bio-inspired nano-traps for uranium extraction …

24-4-2018 · Uranium extraction is important for both uranium recovery and nuclear waste management. Here, inspired by the high sensitivity of proteins towards specific metal ions, Ma and colleagues demonstrate that introducing secondary coordination spheres into amidoxime-functionalized porous polymers can enhance their uranyl chelating abilities.

Decision approaches on Terrafame uranium …

11-6-2019 · There are "no radiation safety-related obstacles" for granting multi-metal company Terrafame a permit to recover uranium as a by-product from its Sotkamo mine, the Finnish Radiation and Nuclear Safety Authority has told the government. The government will now make the final decision on whether to issue the permit.

Ultrafast and Highly Selective Uranium Extraction …

For the practical extraction of uranium from seawater, adsorbents with high adsorption capacity, fast equilibrium rate, high selectivity, and long service life are needed. Herein, a chimeric spidroin‐based super uranyl‐binding protein (SSUP) fiber was designed by fusing the gene of super uranyl‐binding protein (SUP) with the gene of spidroin.
