Paper Abstract

The Lasentec M600F FBRM particle size and population monitor (Lasentec, Redmond, WA) was selected for deployment on radioactive slurry transfer systems at Oak Ridge National Laboratory and Hanford after extensive testing with `physical simulants.' These tests indicated that the monitor is able to measure the change in particle size distribution of concentrated (up to 35 vol.%) slurries at flow rates greater than 2 m/sec. As well, the monitor provided relatively stable mean particle size values when air bubbles were introduced to the slurry pipe test loop and when the color of the slurry was altered. Slurry samples taken during each test were analyzed with a laboratory particle size monitor. For kaolin slurry samples (length-cubed weighted mean of around 55 micrometers ), the Lasentec M600F FBRM in-line monitor measured length-cubed weighted mean particle sizes within 25% of those measured by a laboratory Lasentec M500LF monitor. This difference is thought primarily to be the result of sample handling issues. Regardless, this accuracy is acceptable for radioactive slurry transfer applications. Once deployed, the in-line Lasentec monitor is expected to yield significant cost savings at Hanford and Oak Ridge through the possible reduction in risk of pipeline blockage. In addition, fewer samples of radioactive slurries will need to be measured in the laboratory, further reducing costs and increasing safety.
