Behavior of Trace Ruthenium in Plutonium Purification Cycle

摘要

正The ratio of radioactive ruthenium is more than other species in the radioactive material of spent fuel, so it must be taken out. The influences of time of phase contact, phase ratio, concentration of HNO3 on the extraction of Ru in nitric acid solution and the influences of flow ratio, the concentration of HNO3 in 2AF, extracting series,scrubbing series and the concentration of Uranium in 2AF on countercurrent extraction
