Abstract
Extended reach sluicer systems, devices, and methods for breaking up and retrieving chemical, radioactive, hazardous materials and/or other waste and/or other material from storage tanks with mechanical arms and nozzles to break up and transfer tank material. And this invention can work with tanks having high temperature or low temperature conditions.
Claims19
A large riser extended reach sluicer and tool changer comprising:
- a vertically adjustable upper mast section that mounts to existing riser structures of a waste tank approximately 34 inches in diameter;
- a movable cleaning boom arm having one end attached to the mast section and an opposite end with a changeable end effector;
- a nuclear waste pump system on a distal end of the upper mast section, comprising:
- a submersible pump assembly that fits through an upper mast;
- and a hydraulically driven pump motor for high power density and for safe operation in areas in the waste tank with hazardous/explosive vapors;
- a level indicator;
- wetted parts constructed of stainless steel to allow for decontamination;
- a hydraulic power unit with displacement limiting features to keep system pressures in a safe operating range;
- one or more seals that prevent a waste stream from contaminating a hydraulic fluid;
- one or more seals with recirculating barrier fluid that is cooled through a heat exchanger comprised of a helical path traversing the outside diameter of a discharge piping;
- an accumulator to compensate for changes in barrier fluid pressure and temperature;
- and a sump tank housing a pump mounted at a distal end of a telescoping mast.
