TL;DR: The removal of volatile radionuclides generated during used nuclear fuel reprocessing in the US is almost certain to be necessary for the licensing of a reprocessed facility in the United States as discussed by the authors.

TL;DR: X-ray diffraction results showed the formation of crystalline SnI 4 and SnI4(S8)2, revealing that the iodine binding in these materials is mainly due to a chemisorption process, although a small amount of physisor adaptation was observed.

TL;DR: In this paper, a Universal Extraction (UNEX) process for simultaneously removing the major radionuclides (Cs, Sr, actinides, and lanthanides) from acidic radioactive waste in a single solvent extraction process is presented.

TL;DR: In this paper, a TRUEX flowsheet has been tested using a thirty-stage, 5-cm centrifugal contactor pilot plant using a non-radioactive feed surrogate and data were collected and analyzed to evaluate removal efficiencies of the lanthanides.

TL;DR: An engineering-scale contactor test bed was built at Idaho National Laboratory to perform solvent extraction testing for the partitioning of hexavalent americium as mentioned in this paper, where raffinate simulant feed was spiked with 243Am and 139Ce and treated with sodium bismuthate to oxidize americium to Am(VI), filtered and contacted with 1 M DAAP/dodecane using centrifugal contactors.
