Imaging, inspection, and characterization systems for underground storage tank remediation

Abstract

Underground storage tanks (USTs) containing radioactive and hazardous wastes represent a significant remediation problem for the Department of Energy (DOE). Within the DOE complex are numerous waste storage tanks that will require remediation during the coming decades. Most of these tanks have reached their design life and many are out of compliance with current regulations. Because of the high radiation levels and the chemical hazards present, it will be necessary to perform the remediation operations remotely. The application of robotic systems to remediate USTs offers opportunities for safer, faster, and cheaper solutions over the duration of these cleanup operations. If these robotic systems are to operate safely in the tanks, remote inspection and characterization systems must be developed and tested.
