US PPPL Reconstructs 70-Year-Old Lawson Criterion, Proposes New Fusion Ignition Pathway of "Heat First, Fuel Later"

The Princeton Plasma Physics Laboratory (PPPL), under the U.S. Department of Energy (DOE), released its latest findings on October 5. Laboratory physicists have reconstructed the classic Lawson criterion that has been in use for over 70 years and published the results in Physical Review Letters. The research team integrated four real-world physics effects that were previously treated separately into a unified model, mapping out an entirely new fusion ignition topography. The study shows that adopting a pathway of first heating the plasma and then increasing fuel density can achieve the ignition conditions for self-sustaining burn with far less energy consumption than traditional pathways. For over 70 years, the nuclear fusion field has relied on...

Blue Energy becomes the first small nuclear power developer to apply for grid connection in Texas, aiming to provide baseload power for AI data centers

According to local U.S. media reports, nuclear energy startup Blue Energy Global Inc. has formally submitted a grid connection application to the Texas grid operator, becoming the first developer in the United States to apply to connect next-generation small modular reactor (SMR) power to the Texas main grid (ERCOT). The move is aimed at addressing the explosive growth in baseload electricity demand in Texas driven by the construction of artificial intelligence (AI) and supercomputing data centers. According to the relevant project plans submitted by Blue Energy, the company is advancing the development of a large energy complex in partnership with data center operator Crusoe Inc. The hybrid energy base is initially planned to first rely on natural gas units for rapid commissioning and power generation to address the urgent short-term power shortage of computing clusters; subsequently, small nuclear reactors will be gradually added and deployed to comprehensively build a long-term stable energy supply architecture featuring "gas-nuclear synergy and carbon-free transition."
