Section: claims

1. Apparatus for isolating hazardous radioactive waste for disposal comprising: a) a bifurcated centrifugal casting mold having at least two separable mold parts, said mold being supported for rotation about a first axis;  b) means for supporting a completed monolith in said apparatus with the mold parts removed therefrom;  c) powered drive means for rotating said mold and said monolith about said first axis;  d) mold removal means aligned along a second axis substantially perpendicular to said first axis for removing the separate parts of said bifurcated casting mold from a monolith while leaving said monolith supported in said apparatus for rotation about said first axis;  e) means for injecting a charge of radiation shielding material into a pre-formed shell placed in said mold; and  f) means for heating the interior of said shell during rotation of said mold about said first axis. 2. The apparatus of claim 1, wherein said means for supporting comprises a gripping chuck and a retaining collar each having an aperture for receiving an axially extending hub on said shell, said gripping chuck and said retaining collar being moveable toward and away from each other along said first axis into and out of engagement with said hubs for supporting said shell. 3. The apparatus of claim 1, wherein said mold removal means comprises: a pair of linear actuators, each of said actuators having a mold engaging end which is removeably attachable to a respective one of said mold halves for supporting said mold halves when said actuators are attached thereto. 4. The apparatus of claim 3, further comprising a threaded connector affixed to the mold engaging end of each of said actuators, said mold halves each have a threaded connector affixed thereto for engagement with said actuator connectors, and means for rotating said actuator connectors. 5. The apparatus of claim 1, wherein said means for injecting comprises: an elongated generally cylindrical feed wand receivable in said shell through a fluid inlet port, said wand having a distal end which is receivable in a fluid outlet port to block said outlet port. 6. The apparatus of claim 5, further comprising means for moving said feed wand longitudinally into and out of said shell. 7. The apparatus of claim 5, wherein said means for heating comprises an elongated electrical radiation heater disposed in said shell and extending axially therein from end to end of said shell for blocking both said fluid inlet port and said fluid outlet port during biaxial rotation of said shell during curing of said radiation shielding material therein.
