How is nuclear fusion energy obtained?

Answer 1

In the Sun and other stars, the fusion reactions occur under enormous pressure and incredible heat. These conditions cannot be replicated on Earth.

However, a reasonable facsimile of the fusion reaction can be simulated by using hydrogen and lithium compounds, and applying a short burst of concentrated energy (usually by lasers). This theoretically can force an implosion that for a brief moment provides the necessary particles, heat, and pressure to intitiate fusion.

So far, no fusion reactions have generated more energy than they required.

Answer 2

Usual forms of mining are used to obtain (say) uranium ore, which is then refined into yellow cake. This then is further refined to extract the isotopes most useful as a nuclear fuel.

The waste uranium is used as DU Depleted Uranium for bullets, and ship keels. It has a high penetration, and is 'self-sharpening' in bullet use. This is not a benign material because of radioactivity, particularly as a dust breathed in. .

If one wishes bomb-grade fuel, this is refined as uranium hexafluoride, by a series of centrifuges, and is an expensive process.

Other materials are suitable as reactor fuel, but as they do not produce weapons-grade by-products, they are ignored at the moment. Thorium would be in the vanguard here.

Answer 3

Nuclear fusion energy is obtained by combining light atomic nuclei, such as hydrogen isotopes, under high temperature and pressure conditions. This process releases vast amounts of energy in the form of heat and light. It holds potential as a clean and abundant energy source, but currently faces technological challenges in achieving sustained fusion reactions.
