The centrifuge which has the subtlety information concerning the nuclear nonproliferation used for uranium enrichment technical development exists in the uranium enrichment facilities of Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency. This centrifugal is performing separation processing of the radioactive material adhering to the surface of parts by wet decontamination of ultrasonic cleaning by dilute sulfuric acid and water, etc. By removing the uranium contained in waste fluid, generated sludge reduces activity concentration. And the possibility of reduction of sludge processing is examined. For this reason, from the 2007 fiscal year, Nuclear Science and Engineering Directorate and cooperation are aimed at, and development of the extraction separation technology of the "uranium" by the emulsion flow method is furthered. The test equipment using the developed emulsion flow method was tested. And dilute sulfuric acid and water were used for the examination as actual waste fluid. The result checked whether the various performances in Basic test carried out in Nuclear Science and Engineering Directorate would be obtained.

Alkyl diamide amine (ADAAM) was investigated for the separation of MA(III). ADAAM is a multidentate ligand comprising one soft N-donor atom and two hard O-donor atoms as part of its central frame. This tridentate set of donor atoms provide selective binding for Am(III) and Cm(III) in highly acidic media and yield separation factors of up to 5.5. A continuous liquid-liquid extraction and stripping test was performed using ADAAM(EH) in n-dodecane as the extractant in a multistage countercurrent mixer-settler extractor. Separation of Am(III) and Cm(III) in very high yield was demonstrated.
