Fusion office bill introduced in line with DOE reorganization plan
Cornyn
Padilla
Sens. Alex Padilla (D., Calif.) and John Cornyn (R., Texas) have introduced bipartisan legislation to formally establish the Office of Fusion at the Department of Energy. This move seeks to codify one of the many changes put forward by the recent internal reorganization plan for offices at the DOE.
Companion legislation has been introduced in the House of Representatives by Reps. Don Beyer (D., Va.) and Jay Obernolte (R., Calif.), who are cochairs of the House Fusion Energy Caucus.
Details: According to Obernolte, “Congress must provide clear direction and a coordinated federal strategy to move fusion from the lab to the grid, and this legislation does exactly that.”

High-frame-rate neutron radiography is used to observe the behavior of a high-temperature (773 K) molten Pb-Bi alloy dropped into a vessel that contains water. Experiments are also performed with an empty vessel. Using high-speed cameras combined with image intensifiers and a high-flux neutron source, the interactions among the molten and solidified alloy with water and steam are visualized at imaging rates of 500 and 125 frames/s. The behavior of the melt and steam bubbles is observed clearly in contrast to water. Observation of AuCd3 tracer particles in the molten metal dropped into the vessel that contains water is also successful. The velocity distribution in the melt is measured successfully by means of particle image velocimetry (PIV) using tracer particles. This visualization technique proves to be a promising tool to observe and measure the rapid and complex phenomena of a metal-gas-liquid mixture.
