摘要： Methods of producing cesium-131. The method comprises dissolving at least one non-irradiated barium source in water or a nitric acid solution to produce a barium target solution. The barium target solution is irradiated with neutron radiation to produce cesium-131, which is removed from the barium target solution. The cesium-131 is complexed with a calixarene compound to separate the cesium-131 from the barium target solution. A liquid:liquid extraction device or extraction column is used to separate the cesium-131 from the barium target solution.

摘要： A self-cleaning rotor assembly for a centrifugal separator can be thoroughly cleaned of accumulated solids without disassembly of the separator. The rotor assembly comprises a fully welded, enclosed rotor body. The rotor assembly has a double-ended, hollow axial shaft. The bottom end of the axial shaft extends through the separator housing and has a high pressure fluid coupling. A plurality of spray nozzles are fitted to the axial shaft within the rotor body. The spray nozzles are arranged to spray a washing fluid radially onto the interior surfaces of the rotor. The interior volume of the rotor is divided into a plurality of chambers by a corresponding plurality of axial vanes. At least one nozzle is disposed within each of the chambers.

摘要： A centrifugal separator has a housing with a generally cylindrical inner surface defining an inner chamber. A hollow rotor is disposed within the chamber for rotation therein. At least one inlet is provided for introducing a liquid mixture into the annular volume between the rotor and the housing, where it is then directed into the rotor. An upper rotor assembly separates the liquid mixture by phase densities with the disparate components directed to respective outlets. In one embodiment of the invention, the upper rotor assembly includes an easily removable weir ring to facilitate "tuning" of the separation process. The rotor of the separator is mounted on a unitary rotor shaft that extends axially through the separation chamber to upper and lower bearing assemblies in the separator housing. The bottom surface of the housing, where the liquid mixture is directed from the annular mixing volume into the rotor, preferably includes a plurality of radial vanes that are curved in the direction of rotation of the rotor to assist in directing the liquid mixture with minimal turbulence. Collector rings for the separated components provided from the upper rotor assembly are preferably formed integrally in the wall of the housing with a smoothly contoured peripheral surface to reduce turbulence of the output streams.
