With the 4 billion tons of uranium estimated to be dissolved in the earth & apos;s oceans, an essentially unlimited resource is available to those with easy and affordable access. With decades of research towards the extraction of uranium from seawater, focus has been directed towards the selectivity of the adsorbent material, the cost of the material, and the ability of the adsorbent to be recycl ...

Computer simulations of multi-phase flows are important for many applications. In the proposed work, we plan to advance Eulerian-Lagrangian methods by using Adaptive Mesh Refinement for multi-scale resolutions, and CPU-GPU parallelization to drastically reduce computing time. Eulerian-Lagrangian methods treat the gas/liquid phase as a continuum (Eulerian) fluid, and solid particulates as discrete ...

Tungsten and its alloys are candidates for plasma facing component heat sinks and armor due to their low sputtering rate, high melting point, high thermal conductivity, high strength at elevated temperatures and low tritium inventory. However during service, the plasma facing components will be exposed to a high flux of 14MeV neutrons from the plasma and low energy neutrons from the blanket, whic ...
