Title: Russian Pulsating Mixer Pump Deployment in the Gunite and Associated Tanks at ORNL

Conference ·
OSTI ID:903279

In FY 1998, pulsating mixer pump technology consisting of a jet mixer powered by a reciprocating air supply was selected for deployment in one of the Gunite and Associated Tanks (GAAT) at Oak Ridge National Laboratory (ORNL) to mobilize settled solids. The pulsating mixer pump technology was identified during FY 1996 and FY 1997 technical exchanges between the U.S. Department of Energy (DOE) Tanks Focus Area Retrieval and Closure program, the DOE Environmental Management International Programs and delegates from Russia as a promising technology that could be implemented in the DOE complex. The pulsating mixer pump technology, provided by the Russian Integrated Mining Chemical Company, was tested at Pacific Northwest National Laboratory (PNNL) to observe its ability to suspend settled solids. Based on the results of this demonstration, ORNL and DOE staff determined that a modified pulsating mixer pump would meet project needs for remote sludge mobilization of Gunite tank sludge. This deployment is expected to save costs of operation and maintenance of more expensive mixing systems. The functions and requirements of the system were developed by combining the results and recommendations from the pulsating mixer pump demonstration at PNNL with the requirements identified by staff at ORNL involved with the remediation of the Gunite and Associated Tanks.
