Description
Summary:The treatment and disposal of high level liquid waste(HLLW) is an important factor affecting the sustainable development of nuclear energy. The extraction separation of high-heat-release nuclide 137Cs from HLLW is not only beneficial to the safe disposal of HLLW, but also meeting the needs of 137Cs in many industry fields. In this work, the extraction process for 137Cs from HLLW was proposed with calixcrown as extractant. The process was tested with simulated and real HLLW with a recovery percentage of 99.9% for Cs(Ⅰ) and 99.95% for 137Cs, respectively. The results show that the proposed process for Sr extraction has a bright future in the treatment of commercial HLLW and the recovery of 137Cs in China.
