Technology for removing sludge and cleaning Savannah River Plant radioactive liquid waste tanks

Creators

Description

A new two-step process has been developed for removing sludge and cleaning Savannah River Plant waste tanks scheduled for retirement. Step 1 is a low-pressure, hydraulic-slurrying technique that uses a minimum amount of power to recirculate liquid waste and to suspend sludges. Step 2 is a chemical technique for dissolving unsuspended residue with oxalic acid, and includes water rinses and continued hydraulic slurrying. Full-scale demonstrations of the hydraulic slurrying steps in a waste tank mockup (with kaolin clay as a stand-in for waste sludges) confirmed theoretical predictions that the effective cleaning radius was directly proportional to the momentum of the jet. Small-scale dissolving tests with actual sludges showed that over 95 percent of the sludge could be dissolved in oxalic acid solutions. 24 figures
