The rest of the sun is too cold and too low pressure.

Where does nuclear fusion happen on the sun?
Only at the core, where the temperatures and pressures are high enough.
Where does nuclear fusion occur in a nuclear plant?
No place, we have not yet determined how to make a fusion reactor. Only fusion bombs.
Which part of the newborn star does fusion occur?
In all stars, the fusion only occurs in the inner core.
Does nuclear fusion occur in stars?
Nuclear fusion takes place only in the core of the Sun, or any star. Extremely high energy (temperatures) are required to force atomic nuclei together. The fusion reaction releases heat energy, which continues the fusion of other nuclei.
Nuclear fusion can only occur in areas of?
In areas of high temperature and high pressure
Why does fusion occur in he sun's core but not in other layers?
Thermonuclear reactions only occur in the core of the star because that's where the heat and pressure is so great that it overcomes the forces between the atoms. The surface stars is relatively cool. The Sun is only around 10,000° F on its surface. well below the several million degrees required for fusion.
Do any power plant today run run on nuclear fusion why or why not?
No, because the highest amount of energy needed in a nuclear fusion is 40,000,000 K, which is only known to occur on the sun.
Why doesn't helium fusion occur at the surface?
Because fusion of any kind requires VERY high temperature and pressure, which can take place only in the core of a star.
Does fusion powers many of your nuclear power plants?
Nuclear fusion is used only in experimental installations.
Where does thermonuclear fusion mainly occur?
The only place in the universe where nuclear fusion can occur on its own is in the interior of stars. After closely observing nature, and adapting its laws to fulfill human requirements, our advanced civilization has succeeded in creating nuclear fusion at will, on a small scale. Unfortunately, the only useful application successfully developed so far with our superior intellect is the construction of nuclear bombs and weapons.
Does fusion occur only under extremely high temperatures?
Nuclear fusion of light elements is the process operating in the stars to produce energy, and needs very high temperature to occur. Experiments on earth to aim at producing useful power from fusion have been progressing for many years. The reactants most likely to be used are isotopes of hydrogen, deuterium and tritium. These need to be heated to some hundreds of millions of degrees kelvin before reaction starts. Fusion reactions have been seen, but only for less than 1 second so far. Fusion is not a chemical reaction, it is a nuclear process.
What causes the suns light and heat energy that reaches the earth?
The source of the sun's energy, as well as that of every star, is nuclear fusion in its core. The only way we're able to use nuclear fusion consistently on Earth so far is in the explosions of large nuclear weapons, but we're working on the ability to control other applications.
