Porous tungsten scrubbed by glow discharge cleaning
Researchers conducted experiments in Princeton Plasma Physics Laboratory’s Lithium Tokamak Experiment-Beta (LTX-β) showing glow discharge cleaning can be used to effectively clean samples of porous tungsten—used to hold liquid lithium in fusion machine inner walls—manufactured from powder-reconstituted materials, according to a paper published in Nuclear Materials and Energy.
Tungsten is widely used for plasma-facing components in fusion machines, especially in the divertor region where materials must withstand extreme levels of power flow. According to the paper, spark plasma sintering can be used to make tungsten into spongelike samples for holding liquid lithium.

This panel will examine the status and plans for the comprehensive U.S. government interagency program to address the impacts of uranium contamination in the southwest. The current Ten-Year Plan (2020-2029) builds on the work of the two previous Five-Year Plans (2008-2012 and 2014-2018), including the Tronox Addendum to the 2014-2018 Five-Year Plan. While the past decade represents a significant start in addressing the legacy of uranium mining and milling on the Navajo Nation and other indigenous nations, much more work remains to be done. The project has often experienced difficult technical issues and socio-economic consequences. The panelists, including from federal agencies, will provide updates on, and lessons learned from, remediation activities at former uranium mine and mill sites throughout the west.
