Noun1.nuclear fusion - a nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy
cold fusion - nuclear fusion at or near room temperatures; claims to have discovered it are generally considered to have been mistaken

The fusion reaction pumping out heat and energy end the life span of a star, hence making it a white dwarf star as it is faint, dense and cold.
The fusion reaction in the centre of the sun takes place at 10 million degrees, however CCFE uses temperatures on excess of 100 million degrees to turn the gases into plasma.
At a Press conference on March 23, 1989, the two men announced they had sustained a controlled nuclear fusion reaction in a glass jar that generated four times more energy than they put in.
In fact a fusion reaction generates around a million times more energy than is released in a typical chemical reaction, like those that take place in the human body or when we burn a lump of coal.
As long as lasers have existed, scientists have envisioned harnessing their power to create a fusion reaction that could someday produce an almost limitless stream of carbon-free energy.
In order to create a fusion reaction, where energy is generated by bringing two different atoms together, you would have to use elements from the lighter end of the periodic table such as hydrogen or helium.
But it faces criticism such as: the technologies needed for the ITER project are extremely challenging, especially the technology to sustain plasma; the money should be used to develop renewable energy; high-energy neutrons produced by the fusion reaction will damage the reactor and make it radioactive.
Despite small-scale success in laboratories, no-one has yet developed an effective way of channelling energy from a fusion reaction.
The interpretation of this Gamow function is the tunneling rate of the fusion reaction of cluster of deuterium (for the given data) corresponding to Takahashi data [12], with the difference that here we consider a PT-symmetric periodic potential.

Monday's announcement came just days after reports from North Korean state media that the country's scientists had succeeded in carrying out a nuclear fusion reaction, and thereby made a "breakthrough" in the possible creation of new energy sources.
SEOUL: North Korea, one of the world s poorest countries, said on Wednesday it had succeeded in creating a nuclear fusion reaction to produce energy, a claim called absurd by nuclear experts.
