Fusion reactions have an energy density many times greater than nuclear fission; the reactions produce far greater energy per unit of mass even though individual fission reactions are generally much more energetic than individual fusion ones, which are themselves millions of times more energetic than chemical reactions.
Nuclear fusion is the reverse of nuclear fission, which powers the nuclear plants we’re all familiar with. ... NIF produced 3.15 million joules of fusion energy–enough to boil 10 teapots of ...
When that chemical reaction happens, it gives off energy. Fission vs. fusion. Nuclear fission is the opposite of nuclear fusion in that the former unleashes energy by splitting heavy atoms apart ...

When a sustained nuclear fusion power plant is built, it has the potential to be capable of extracting all the fission energy that remains in spent fission fuel, reducing the volume of nuclear waste by orders of magnitude, and more importantly, eliminating all actinides present in the spent fuel, substances which cause security concerns.

The first successful man-made fusion device was the boosted fission weapon tested in 1951 in the Greenhouse Item test. The first true fusion weapon was 1952's Ivy Mike, and the first practical example was 1954's Castle Bravo. In these devices, the energy released by a fission explosion compresses and heats the fuel, starting a fusion reaction.
What is nuclear fusion? Nuclear energy being created today uses a reaction called fission, which works by splitting uranium atoms, releasing large amounts of energy in the process.
The latter figure means that a nuclear fission explosion or criticality accident emits about 3.5% of its energy as gamma rays, less than 2.5% of its energy as fast neutrons (total of both types of radiation ~6%), and the rest as kinetic energy of fission fragments (this appears almost immediately when the fragments impact surrounding matter, as ...
