Waste retrieval system development and demonstration
- Pacific Northwest National Lab., Richland, WA (United States)
Waterjet technologies are being developed and applied to radioactive waste retrieval, processing, and system decontamination. Benefits from this approach include control of waste dilution and dissolution, the ability to clean tank surfaces, and selective removal of surface contaminants. Systems under development include: pulsed air mixers as an alternative to mixer pumps to maintain slurries in suspension; borehole miner with an extendible nozzle as an enhancement of sluicing; confined sluicing end effector with jet pump retrieval for breakup and removal of sludges and solids; and scarifier with pneumatic conveyance for fracture and removal of sludges and harder solids without water accumulation or appreciable waste dilution and surface decontamination. Two systems are being developed for demonstration in radioactive tanks in Fiscal Year 1997: the confined sluicing end effector for retrieval of waste from tanks W3 and W4 at Oak Ridge National Laboratory and extendible nozzle for zeolite, heel breakup at Savannah River Site tank 19.
