In December 2022, the National Ignition Facility at Lawrence Livermore National Laboratory in the United States achieved net energy gain from controlled nuclear fusion (Q>1) for the first time, with laser input of about 2.05 megajoules and fusion output of about 3.15 megajoules.

UnverifiedNet energy gain from controlled nuclear fusion (Q>1) means the energy released by the fusion reaction exceeds the energy consumed to sustain the reaction, i.e., scientific energy breakeven; however, the 2022 National Ignition Facility result is only a gain from laser to fusion energy, and when full-system energy consumption is included, it remains very far from engineering feasibility.73% similarUnverifiedIn July 2023, Lockheed Martin was awarded a contract of approximately $499 million to build the ARIES experimental flight vehicle equipped with a nuclear thermal rocket engine, with the nuclear fission reactor designed and manufactured by BWX Technologies using HALEU fuel.59% similarUnverified电子-离子对撞机（EIC）是美国布鲁克海文国家实验室正在建设的下一代核物理设施，预计2030年代初投入运行，预算约20亿美元57% similarUnverified核聚变单位质量释放的能量约为化学燃烧的1000万倍57% similarUnverifiedITER (International Thermonuclear Experimental Reactor) is expected to achieve full-power operation in 2035.57% similar
