Cs Extraction from Chloride Media by Calixarene Crown-Ethers
Asse II salt mine, in Germany, contains low and intermediate-level radioactive waste that must be retrieved in the upcoming years. Potentially contaminated salts and brines will require treatment, with 137Cs being the main contaminant. Cs+ is problematic

The role of the 5f valence orbitals of early actinides in chemical bonding
Understanding the chemistry of heavy radioactive elements is crucial to harnessing them for fuel and medicine. Here, the authors combine advanced X-ray spectroscopy and modelling to the study the chemical bonding of the 5fvalence orbitals of uranium ...

Selective Americium Separation: New Insights into the Complexation of Trivalent f-Elements with SO3-Ph-BTBP [PDF]
In the Americium selective (AmSEL) process, the N-donor ligand 3,3’,3’’,3’’’-([2,2’-bipyridine]-6,6’-diylbis(1,2,4-triazine-3,5,6-triyl))tetrabenzenesulfonate (SO3-Ph-BTBP) is used to selectively strip Am(III) from a N,N,N’,N’-tetraoctyl diglycolamide ...

Progress and Challenges of Materials and Methods for Uranium Extraction From Seawater
The ocean covers 70% of the earth’s area, and the seawater uranium is more than 1000 times that of terrestrial uranium ore. In order to increase the power generation and ensure the sustainable operation of nuclear power plants, the development of ...

Linear thermal expansion behavior of compacted bentonite buffer materials
In a geological repository system, buffer is indispensable to ensure the safe disposal of high-level radioactive waste (HLW). Because heat generated from spent nuclear fuel in a canister is released to the surrounding buffers, thermal properties of such ...
