Abstract: An attachment assembly is provided for coupling a portable barricade to an overhead door, including a clamp, the clamp having a first surface and a second surface, the second surface facing the overhead door, a fastener passing through a clamp opening of the clamp and through an opening of the overhead door, a coupling member operably engaged with the fastener, and a biasing element positioned between the second surface of the clamp and the overhead door, wherein, when the coupling member is actuated in a first direction, the biasing element is compressed, shortening a distance between the clamp and the overhead door.

Abstract: Described are method of treating a radioactive organic waste stream comprising: (a) mixing a radioactive organic waste stream comprising organic compounds and radionuclides with phosphoric acid to form a reaction mixture; (b) heating the reaction mixture to a desired temperature in the presence of an oxidant to oxidize organic compounds present in the waste stream, and removing oxidized organic compounds from the reaction mixture; (c) optionally, adding a reducing agent to the reaction mixture to form insoluble radioactive metal phosphate compounds comprising one or more of the radionuclides, and separating the insoluble radioactive metal phosphate compounds from the reaction mixture; (d) optionally, adding a fluorine compound to the reaction mixture to react with uranium that may be present in the reaction mixture to form uranium hexafluoride, and removing uranium hexafluoride from the reaction mixture; (e) adding ammonia to the reaction mixture to neutralize phosphoric acid and to form ammonium phosphate
