Research Progress of Alkaline Process of Spent Nuclear Fuel Reprocessing by HAN Zhe, GAO Yuan, WANG Chun-hui, QIU Jie, HE Hui, JIAO Cai-shan

“…The alkaline process of spent nuclear fuel(SNF) reprocessing refers to reprocessing methods that use the alkaline solution of carbonates or hydroxides as the media to conduct the dissolution of SNF and subsequent separations of uranium, plutonium and other elements. Most of the fission products and minor actinides are either insoluble or changed to insoluble carbonates or hydroxides during the alkaline dissolution of SNF, indicating that the resulted dissolver solution contains less amount of fission and minor actinide elements. …”

A scenario study on the transition to a closed nuclear fuel cycle using the nuclear energy system modelling application package (NESAPP) by Andrianov Andrei A., Andrianova Olga N., Kuptsov Ilya S., Svetlichny Leonid I., Utianskaya Tatyana V.

“…Ten possible scenarios are considered which differ in the shares of thermal and sodium-cooled fast reactors, including options involving the use of mixed uranium-plutonium oxide fuel in thermal reactors. The evolution of the following performance and sustainability metrics is estimated for the period from 2020 to 2100 based on the considered assumptions: annual and cumulative uranium consumption, needs for uranium enrichment capacities, fuel fabrication and reprocessing capacities, spent fuel stocks, radioactive wastes, amounts of plutonium in the nuclear fuel cycle, amounts of accumulated depleted uranium, and the levelised electricity generation cost. …”
