Nuclear fusion–fission hybrid. 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.
v. t. e. Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes), combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or absorption of energy.
History of nuclear fusion. The history of nuclear fusion began early in the 20th century as an inquiry into how stars powered themselves and expanded to incorporate a broad inquiry into the nature of matter and energy, as potential applications expanded to include warfare, energy production and rocket propulsion.
Learning from the sun. Nuclear fusion occurs when two atoms of a light element such as hydrogen are heated and fused together to form a heavier element such as helium. In order for that process to ...
Nuclear fusion is the reverse of nuclear fission, which powers the nuclear plants we’re all familiar with. Fission splits atoms of very heavy, unstable isotopes like uranium 235 and captures the ...
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission was discovered by chemists Otto Hahn and Fritz Strassmann and physicists Lise ...
The Soviet RDS-6S test, code named "Joe 4", demonstrated a fission/fusion/fission ("Layercake") design for a nuclear weapon. Linear pinch devices in the US and USSR report detections of neutrons, an indication of fusion reactions. Both are later explained as coming from instabilities in the fuel, and are non-fusion in nature. 1954
A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven, or in ...
