Why Fusion Is Not Working?

What is the main problem with fusion?

But fusion reactors have other serious problems that also afflict today’s fission reactors, including neutron radiation damage and radioactive waste, potential tritium release, the burden on coolant resources, outsize operating costs, and increased risks of nuclear weapons proliferation..

Why is it so difficult to get fusion reactions to work?

On Earth it is very difficult to start nuclear fusion reactions that release more energy than is needed to start the reaction. The reason is that fusion reactions only happen at high temperature and pressure, like in the Sun, because both nuclei have a positive charge, and positive repels positive.

Why does fusion not occur on Earth?

Normally, fusion is not possible because the strongly repulsive electrostatic forces between the positively charged nuclei prevent them from getting close enough together to collide and for fusion to occur.

Why is fusion so hard?

Without the electrons, atoms have a positive charge and repel. This means that you have to have super high atomic energies to get these things to have nuclear fusion. High energy particles are the problem. This is why fusion is difficult and fission is relatively simple (but still actually difficult).

What happens if a fusion reactor fails?

A nuclear fusion reaction inside a thermonuclear weapon is commonly referred to as a Hydrogen bomb or thermonuclear weapon. However in energy production, the fusion reaction can not “explode.” In theory- if you lose containment of a fusion reactor, all of that energy is released. It would look a lot like an explosion.
