Russian Pulsating Mixer Pump Deployment in the Gunite and Related Information

Effects of mixing duration on engineering properties of

The initial concrete flow suggests good workability, but depending on mixing durations, remarkable variations in the workability retention over time were observed. For concrete with 1 min of mixing, the mix was workable for little more than 15 min after the discharge and was followed by rapid …

Cold Testing of a Russian Pulsating Mixer Pump at - CORE

Abstract. Russian pulsating mixer pump (PMP) technology was identified in FY 1996 during 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 technology that could be implemented in tank waste retrieval operations in the United States.

Russian Pulsating Mixer Pump

The U.S. Department of Energy deployed a Russian pulsating mixer pump—a reciprocating, air-operated mixer—in January 2001 at the Oak Ridge Reservation. The Russian mixer was deployed in tank TH-4 to mobilize a 2.5-foot layer of sludge. The Russian mixer mobilized the …

EM-50 Tanks Focus Area Retrieval Process Development and

Russian Retrieval Equipment Testing The pulsating pump and pulsating monitor from Russia were tested to provide an initial evaluation of the equipment for possible deployment in DOE waste tanks. The evaluation of potential end users was conducted to determine whether the conceptual design of the equipment could be adapted to their needs.

Functions and Requirements for Russian Pulsating Monitor

This document provides functions and requirements to support deployment of pulsating mixer pump technology in the Oak Ridge National Laboratory (OW) Gunite and Associated Tanks to mobilize and mix the settled sludge and solids in these tanks. In FY 1998 pulsating mixer pump technology, a jet mixer powered by a reciprocating air

The Oak Ridge Russian pulsating mixer pump (PMP) system was designed with the flexibility to permit deployment in a variety of cylindrical tanks. The PMP was installed at the Tanks Technology Cold Test Facility at the Oak Ridge National Laboratory (ORNL) to assess the performance of the system over an extended range of operating conditions

Appendix G Tank Waste Retrieval Techniques and Experience

The retrieval strategy for the Gunite and associated tanks focused on the use of a wide variety of tools and systems working either individually or in concert. Axial-flow propeller mixers (i.e., Flygt mixer) were used for waste retrieval from one tank. The Russian Pulsating Mixer Pump (PMP) was used for …
