Summary
Approximately 140,000 m³ (37 Mgal) of waste material now resides in 149 SSTs single-shell tanks. These tanks are of an early design that consists of a carbon-steel liner surrounded by a reinforced structural concrete shell. Originally designed for a 20-year life, the first of those constructed are surpassing that expectation. Many have lost confinement integrity, and leaks to the environment have been detected. These wastes present a significant recovery challenge. The goal is to develop and field retrieval systems with the capability to remove wastes from these tanks and transfer those wastes for further downstream processing. The application of existing technologies has been the foundation of the retrieval strategy. However the aggressive schedules and complexity of the wastes to be recovered have required the search for and the development of more advanced technologies. This paper discusses the long-term strategy that has been developed to support the waste retrieval efforts of the Tank Waste Remediation System program.
