The U.S. Department of Energy (DOE) today announced $2.3 million in funding for 10 projects that will pair private industry with DOE’s National Laboratories to overcome challenges in fusion energy development, an area of research that captivated global attention in December when the Department announced that a team at Lawrence Livermore National Laboratory had achieved fusion ignition. Ignition, in which more energy was derived from fusion than was put into it, had never been accomplished before in a laboratory setting and raised hopes that fusion energy could play a major role in the transition to clean energy.

Creating a fusion plasma requires deep understanding of the behavior of various isotopes of hydrogen. But plasma scientists have long been puzzled by a mysterious contradiction– the disconnect between theoretical predictions and experimental observations of how fusion energy confinement varies with the mass of hydrogen isotopes used to fuel the plasma. A new analysis has helped unravel this mystery.

PPPL scientists have created a plan using liquid lithium to keep the full force of extreme and potentially damaging heat from hitting the divertor region that will release heat from future tokamak fusion facilities.
One of the great challenges in fusion tokamaks is how to keep the core of a plasma hot enough that fusion can occur while maintaining a temperature at the edge of the plasma low enough that it doesn’t melt the tokamak’s walls. This requires dissipating the heat and particles flowing towards the wall without reducing the performance of the core. Researchers recently developed a pathway to addressing this core-edge integration challenge.
