Crystal accumulation in the Hanford Waste Treatment Plant high level waste melter: Summary of FY2016 experiements

Crystal Accumulation in the Hanford Waste Treatment Plant High Level Waste Melter: Summary of 2018 and 2019 Experiments

“…A series of experiments was completed with the room temperature system in fiscal year 2016. 9 Accumulation of particles was observed at the bottom of the riser and along the bottom of the throat after each experiment. Measurements of the accumulated layer thicknesses showed that the settled particles at the bottom of the riser did not vary in thickness during pouring cycles or idle periods.…”

Crystal accumulation in the Hanford Waste Treatment Plant high level waste melter: Summary of 2017 experiments

“…Note that the data from experiments 1-4 were included in the 2016 report. 12 Also note that experiments 11-17 were conducted with the feed tank agitator left running during the idle period. Additional observations from experiments 11-17 related to particle flow with the feed tank agitator running are included in the next section.…”

“…A series of experiments was completed with the room temperature system in fiscal year 2016. 12 In those experiments, a prototypic pour rate was maintained based on the volumetric flow rate. Accumulation of particles was observed at the bottom of the riser and along the bottom of the throat after each experiment.…”
