Nuclear fusion

In the field of nuclear fusion, isotopic gases—through precise selection of nuclides and meticulous control of their abundances—serve multiple functions, ranging from the supply of fusion fuel and tritium breeding for self-sustaining operation to the exploration of advanced fuel cycles. Isotopes such as deuterium, tritium, helium-3, and lithium-6 constitute a complete fuel system that spans from first-generation D–T fusion to the ultimate D–³He fusion, serving as the core foundational materials for breaking through the commercialization bottlenecks of fusion energy and realizing the vision of clean, limitless energy.
