Extraction of Valuable elements in Spent Nuclear Fuel by using Pyridine Resin

摘要

Many kinds of elements are present in the spent nuclear fuel. If we extract these elements from the spent fuel, these elements will become a valuable resource. We have proposed two concepts for (he separation of these elements. One is an entirely new reprocessing process using hydrochloric acid solution. Another is the adding system with the existing reprocessing process or the extended existing reprocessing process. Our proposed two concepts are used as pyridine resin as separation media. In the present paper, the extraction methods of these valuable elements from the spent fuel solution are reported.
