  • Patent number: 8905909
    Abstract: A system for filling a container with hazardous waste includes a primary confinement chamber that houses a lid handling mechanism and a filling head. The lid handling mechanism may be used to remove and/or recouple the lid to the container as part of the process of filling the container in such a way to ensure the exterior of the container is not contaminated by the hazardous waste. The filling head may be configured to add the hazardous waste to the container, mix the contents of the container, and/or vent air from the container.

The system may include additional mechanisms in the primary confinement chamber to add dry cementitious material to the container, add premixed wet cementitious materials to the container, add cementitious material to seal off the top of the lid, and/or measure the level and test whether the contents of the container meet quality assurance requirements. The hazardous waste may include radioactive hazardous waste.
