Fusion powers stars and produces virtually all elements in a process called nucleosynthesis. The Sun is a main-sequence star, and, as such, generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 620 million metric tons of hydrogen and makes 616 million metric tons of helium each second.
“Fusion, on the other hand, does not create any long-lived radioactive nuclear waste.” The waste byproduct of a fusion reaction is far less radioactive than in fission, and decays far more ...
And while much has been made of the fact that fusion doesn’t produce long-lasting radioactive waste in the way that fission does, it relies on tritium, a radioactive isotope of hydrogen.
And existing nuclear energy, which accounts for 19%, generates radioactive waste that will last centuries. For answers to our energy needs, scientists have turned to the sun.
In 2024, Commonwealth Fusion Systems announced plans to build the world's first grid-scale commercial nuclear fusion power plant at the James River Industrial Center in Chesterfield County, Virginia, which is part of the Greater Richmond Region; the plant is designed to produce about 400 MW of electric power, and is intended to come online in ...
Hybrid nuclear fusion–fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The basic idea is to use high-energy fast neutrons from a fusion reactor to trigger fission in non-fissile fuels like U-238 or Th-232. Each neutron can trigger several fission events ...
Fusion is near limitless, produces no planet-heating pollution and unlike fission, the nuclear technology the world currently uses, it leaves no legacy of long-term nuclear waste.
Greenpeace falsely claimed that nuclear fusion is unsafe and produces waste like nuclear fission. [27] However, nuclear fusion does not produce long lived nuclear waste nor is there a meltdown risk because the conditions required to sustain nuclear fusion mean that if there is a containment breach, the fusion reaction would simply halt.
