Abstract
A system and method for filling, dewatering and sealing high integrity containers for storing high level radioactive debris has a support structure for receiving a container and a movable hood supported over the support structure. The movable hood is movable between a filling/dewatering position, an intermediate position, and a sealing position. Fill and dewatering lines extend through the hood and have flexible lower portions with connectors for interfacing with the container to be filled. The flexible lower portions are movable into and out of engagement with respective connectors on the container when the hood is in the filling/dewatering position. A plurality of valves are provided to isolate the fill and dewatering lines to minimize release of radioactive debris during connector mating and demating operations. A straw extends through the hood for removing water from an upper volume of the container when the hood is in the intermediate position. A closing structure is supported by the hood for lowering a cover into engagement with the container and fastening the cover to the container when the hood is in the sealing position. A vent line is provided for purging gas from the hood. A vibrator is positioned within the support structure for engaging and vibrating the container to facilitate filling and dewatering operations. A scale is positioned between the container and the support structure for determining when the container is full.
