Is nuclear fusion a good power source?

Fusion has the potential to provide the kind of baseload energy needed to provide electricity to our cities and our industries. Sustainability: Fusion fuels are widely available and nearly inexhaustible. No long-lived radioactive waste: Nuclear fusion reactors produce no high activity, long-lived nuclear waste.

What is the main source of nuclear fusion?

hydrogen
The main fuels used in nuclear fusion are deuterium and tritium, both heavy isotopes of hydrogen. Deuterium constitutes a tiny fraction of natural hydrogen, only 0,0153\%, and can be extracted inexpensively from seawater. Tritium can be made from lithium, which is also abundant in nature.

What is the best definition of nuclear fusion?

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.

What is nuclear fusion and why is it important?

It represents a nearly limitless source of energy that is clean, safe and self-sustaining. Ever since its existence was first theorized in the 1920s by English physicist Arthur Eddington, nuclear fusion has captured the imaginations of scientists and science-fiction writers alike.

Can the UK build the world’s first commercial nuclear fusion power station?

Steve Jones, chief technology officer at the Nuclear AMRC, and professor of Welding Technology at the University of Sheffield The UK is opening a new facility to develop and test materials and manufacturing processes in its quest to build the world’s first commercial nuclear fusion power station.

What is fusion energy and how does it work?

Fusion already happens naturally in stars — including the sun — when intense pressure and heat fuse hydrogen atoms together, generating helium and energy. This process is what powers the sun and makes it so hot and bright. Researchers who work on fusion energy are essentially trying to make tiny stars here on Earth.

How is nuclear fusion ignited?

“A key step on the way to ignition [of nuclear fusion] is to have the energy generated in an inertially-confined fusion plasma exceed the amount of energy deposited into the deuterium–tritium fusion fuel and hotspot during the implosion process, resulting in a fuel gain greater than unity.”
