Method and means for solidifying nuclear waste for permanent disposal are disclosed. A storage container, in the preferred form of a drum or barrel, is charged with a predetermined amount of liquid polymer resin in an uncatalyzed state. Catalyst-containing frangible ampoules are also positioned in the drum with a rotatable mixer mechanism. At a waste filling station, the mixer is rotated to break the ampoules so as to mix the catalyst and the resin. The catalyzed resin is then mixed with added waste material to completely encapsulate the waste prior to solidification of the resin. Monitoring of the filling and mixing process is provided by continually sensing the torque force being applied to the rotating mixer mechanism. Where the waste is a dust-like, dry particulate material, dust control means and method are also provided.

A method of processing radioactive waste material which is to be isolated from the environment as the waste material is received from a source thereof and introduced into a container for disposal comprising: (a) providing enclosure means adapted to receive said container and conduit means adapted to convey said material from said source into said container within said enclosure; (b) disposing said container in said enclosure; closing said enclosure to isolate the container from the environment and sealing the container; (c) detachably connecting said container and conduit with a fluidtight seal within said enclosure to isolate the interior region of the container from the interior region of the enclosure; (d) providing a positive gas pressure difference between the interior regions of said enclosure and container and monitoring said gas pressure difference to verify the integrity of the fluidtight seal between the container and conduit means; and, upon positive verification (e) conveying said material through said conduit means and into said container for disposal.
