Computer modeling of extraction processes has seen significant recent progress. The volume focuses on the PUREX process and its chemistry. The book covers PUREX process layout, flowsheets, chemistry, fission product and neptunium behavior, TBP in plutonium recovery, computer modeling, and TBP as a phase modifier.
Volume 3 is primarily devoted to the PUREX process, with special emphasis on its chemistry. Chapter 1 describes the general process layout and special flowsheets applied in various plants, together with the chemistry of both the product elements and the process reagents. Two more chapters deal with the details of fission product and neptunium behavior in the process. Another nuclear application of tributyl phosphate (TBP) solvent extraction is the recovery of plutonium values from fuel fabrication scrap and similar wastes, which is treated in Chapter 4. Computer modeling of extraction processes is an exciting and most useful area where great progress has been made in recent years, and this is dealt with in Chapter 5. Finally, there are extraction procedures where TBP does not primarily act as an extractant by itself, but instead is used as a phase modifier to improve the compatibility of reactants in a different extractant-diluent system.
