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.

Presented by ANS's Fuel Cycle and Waste Management Division, this international panel explored separating specific radionuclides from waste using recycling technology that enables pure materials to be used for other purposes.
The current global focus is on the need to recycle and reuse the finite resources that exist on the earth. The waste products from nuclear systems are no different. Instead of wastes and a liability, they could actually be a valuable asset! This is especially the case when specific radionuclides can be separated from the waste using recycling technology that enables pure materials to be used for other purposes. Examples include radioisotopes for space applications, medical treatment & interventions and enhancing agricultural methods. This panel explored the need for these materials, the market sectors interested in the technology being proposed and the technology being developed in support of this. The need to consider requirements and uses outside of the conventional nuclear industry, along with the potential for future fuel cycles to incorporate these needs into their development also were discussed.
