  • Patent number: 5416251
    Abstract: Methods for the encapsulation and solidification of waste material, particularly radioactive ion exchange resin bead media, are provided along with the apparatus to accomplish the methods, and the final encapsulated storage article. The ion exchange resin is solidified within a containment vessel by the addition of a thermosettable polymeric binder without the need for a pre-mixing vessel. The resulting exothermic conditions occasioned by the curing of the polymer are controlled by the sequential delivery of the polymeric binder, preferably through an injection lance.
