Outline of Final Research Achievements

In the isotope centrifugal separation, a method using a gas phase has been put to practical use, however, the development of new technology is desired due to enormous cost and size of equipment. Quantitative evaluation of the centrifugation phenomenon in the liquid phase leads to clarification of the mechanism of isotope centrifugal separation in the liquid phase. We created the apparatus for measuring the local concentration in the radial direction of rotation by simultaneously rotating the sample and the NMR signal detector and succeeded in the in situ observation of the centrifugation process. We performed centrifugal experiment using NaI - CsI mixed solution (NaI: CsI = 3.3 mol / L: 1.66 mol / L) as a model of isotope separation in the liquid state. We succeeded in the in situ observation of the centrifugal separation process in the liquid state.
