Why a fission reaction is neccasary for fusion reaction?

It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).


Are nuclear bombs made with nuclear fusion?

Nuclear bombs can use either nuclear fission or nuclear fusion as the primary mechanism of energy release. Most nuclear bombs in current arsenals rely on nuclear fission reactions, while thermonuclear bombs use a fission reaction to trigger a fusion reaction.


How is fusion used in a hydrogen bomb?

a hydrogen bomb is a fusion bomb. even though in standard types of hydrogen bombs 90% of the yield is fission, caused by uranium-238 fission by 15 MeV neutrons from the fusion reaction.


Detonation of a fusion type hydrogen bomb is started by?

Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.


Is chernobyl fission or fusion?

The Chernobyl disaster involved a nuclear fission reaction. Fission is the process of splitting atoms to release energy, which is the fundamental reaction in nuclear power plants like the one at Chernobyl. Fusion, on the other hand, involves joining atoms together to release energy and is the process that powers the sun.
