Solvent cleanup method using activated alumina was discussed in this study. This method was one of candidate to remove TBP/-dodecane degradation products. The degradation sample of 30% TBP/-dodecane was prepared by irradiation (1.6 MGy) using Co -source. The absorbed dose for sample was almost 1.6 MGy. The degradation products were qualitatively analyzed by gas chromatography-mass spectrometer (GC-MS). After the irradiation, solvent cleanup was performed by activated alumina and the cleanup using alumina was examined by phase separation test with 3M HNO. As the result, it was found that hexane and long-chain alcohols were mainly generated as the n-dodecane degradation products by irradiation, and almost 70% of the TBP/-dodecane degradation products were removed and the phase separation performance were improved by the cleanup using activated alumina.

Japan Nuclear Cycle Development Institute (JNC) has been developing centrifugal contactors which are compact and high performance for solvent extraction process in industrial reprocessing plant. Centrifugal contactor has some advantages which are more compact, smaller holdup volume and higher separation performance than conventional contactor such as mixer-settler or pulse column and contributes to economic advantage and reduction of solvent waste. In addition, the compact contactor is easy to manage the critical safety, and the operation ratio for fuel treatment can be improved because of short start-up and shut-down time. Since 1985, JNC stared the development of centrifugal contactor and then fundamental design was established for engineering scale hot test plant (RETF). The life time was evaluated by the result of endurance test, and system performance of multi-stages contactor on engineering scale was demonstrated. [1] In addition, several types of advanced contactors have been developing. This paper introduces the development of centrifugal contactor in JNC
