ABSTRACT:
A system and method for supercritical fluid enrichment of radioactive isotope/s are disclosed. The method involves pressurizing an outer chamber and an inner centrifugal chamber of a stage to supercritical pressure; supplying material including target isotope/s at supercritical pressure to the inner chamber; spinning the inner chamber to centrifuge the material including target isotope/s; providing a differential pressure between the inner chamber and the outer chamber; wherein windows in the inner chamber enable passage of the target isotope or an undesired isotope from the inner chamber to the outer chamber in response to the differential pressure.
