Low-Level and Mixed Radioactive Waste In-Drum Solidification

Abstract

Argonne National Laboratory-East (ANL-E) has begun production-scale testing of a low-level and mixed radioactive waste solidification system. This system will be used to treat low-level and mixed radioactive waste to meet land burial requirements. The system can use any of several types of solidification media, including a chemically-bonded phosphate ceramic developed by ANL-E scientists. The final waste product will consist of a solidified mass in a standard 208-L drum. The system uses commercial equipment and incorporates several process control features to ensure proper treatment. This paper will discuss the waste types requiring treatment, the system configuration, and operation results for these waste streams.
