Fishing for a way to assess mixing behavior in treatment tanks for radioactive waste, ecologists at Pacific Northwest National Laboratory turned to radio frequency technology previously used to track migrating fish. Thousands of passive integrated transponder (PIT) tags were added to a clay simulant and whipped around in tests of mixer equipment in large test tanks and scaled prototypes. This novel application of the PIT tags provided a means of assessing fluid motion without sampling.
Researchers at PNNL are providing performance data for pulse jet mixer and air sparger designs intended for use in Hanford's Waste Treatment Plant. Using a half-scale tank containing about 10,000 gallons of simulated waste, they monitor the performance of the mixers under a variety of conditions.
