The Pacific Northwest National Laboratory (PNNL) has a level 2 milestone (M2FT-16PN030201042) due December 1, 2015 to: Complete the field modeling evaluation and laboratory column experiments and issue a report on the effect of flow rate (linear velocity) on adsorbent performance. As a preface to this level 2 milestone, PNNL produced a level 3 milestone (M3FT-15PN0310053) which described the experimental design for evaluation of current velocity on adsorbent performance. This program is being conducted in collaboration with Costas Tsouris at Oak Ridge National Laboratory (ORNL) for modelling efforts. The objective of this study is to identify at what linear velocity the adsorption kinetics for uranium extraction starts to drop off due to limitations in mass transport of uranium to the surface of the adsorbent fibers. This information will be critical in establishing an oceanic site with sufficient current velocity for optimal adsorbent extraction. This particular investigation is targeted at understanding the effect of lower end coastal currents (
