Electromagnetic Separation of Radioisotopes of the Heavy Elements at the Oak Ridge National Laboratory
Since the early 1940’s some radioisotope separation has been intermittently performed in the calutrons located at Oak Ridge, uranium being the most notable. With minor modifications being made to the equipment, Th230 also has been separated. In 1952 one calutron system was modified to accommodate PuCl3 charge and to provide also for the total containment of plutonium during the separation process. Thus, over the past few years, the isotopes of thorium, uranium, and plutonium have been separated on a recurring basis. Isotopes having much less activity, namely Be10, Bi210, K40, Sm147, etc., have been separated more on a “when needed” basis.
