DRY PRODUCT VALVE ABSTRACT OF THE DISCLOSURE 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 uncata- lyzed 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 cata- lyzed resin is then mixed with added waste material to com- pletely encapsulate the waste prior to solidification of the resin. Monitoring of the filling and mixing process is pro- vided 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.
