The United States Department of Energy (DOE) and the National Nuclear Security Administration (NNSA) announced they have achieved fusion ignition at Lawrence Livermore National Laboratory (LLNL) in Livermore, CA. .“This is a landmark achievement for the researchers and staff at the National Ignition Facility who have dedicated their careers to seeing fusion ignition become a reality, and this milestone will undoubtedly spark even more discovery,” said US Secretary of Energy Jennifer Granholm in a Tuesday press release. .“The Biden-Harris Administration is committed to supporting our world-class scientists—like the team at NIF—whose work will help us solve humanity’s most complex and pressing problems, like providing clean power to combat climate change and maintaining a nuclear deterrent without nuclear testing.”.The release said the NIF conducted the first controlled fusion experiment in history to reach this milestone on December 5. It said this achievement will offer insight into how to produce clean fusion energy, which could speed up efforts to achieve US President Joe Biden’s goal of a net-zero economy. .“We have had a theoretical understanding of fusion for over a century, but the journey from knowing to doing can be long and arduous,” said US Presidential Chief Advisor for Science and Technology and Director of the White House Office of Science and Technology Policy Arati Prabhakar. .“Today’s milestone shows what we can do with perseverance.” .The release went on to say LLNL’s experiment surpassed the fusion threshold by delivering two megajoules of energy to the target, which resulted in 3.2 megajoules of fusion energy output. It added this experiment demonstrated for the first time there is a scientific basis for inertial fusion energy (IFE). .Many advanced science and technology developments are needed to achieve simple, affordable IFE to power homes and businesses, and the DOE is restarting a program for it. There is momentum driving progress towards fusion commercialization. .Fusion is the process by which two light nuclei combine to form a single heavier nucleus, releasing a large amount of energy. A group of scientists at LLNL in the 1960s hypothesized lasers could be used to induce fusion in a laboratory setting. .This idea became inertial confinement fusion, leading to more than 60 years of research and development in lasers, optics, diagnostics, target fabrication, computer modeling and simulation, and experimental design..NNSA Administrator Jill Hruby said December 5 is “a historic day in science thanks to the incredible people at Livermore Lab and the National Ignition Facility.” Hruby said the team from DOE laboratories and international members have “shown us the power of collaboration.”.“In making this breakthrough, they have opened a new chapter in NNSA’s Stockpile Stewardship Program,” she said.
