How does nuclear fusion generate electricity?

Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors.

Why is fission and not fusion used to generate electricity for the world?

Fusion doesn’t produce runaway chain reactions the way fission can, so there’s no need to worry about meltdowns. Nor do fusion reactions produce the large amounts of dangerous radioactive waste that fission reactions do. That’s why it’s such a dreamy source of energy.

Why is fusion so powerful?

Abundant energy: Fusing atoms together in a controlled way releases nearly four million times more energy than a chemical reaction such as the burning of coal, oil or gas and four times as much as nuclear fission reactions (at equal mass). Its major by-product is helium: an inert, non-toxic gas.

Is fusion used to generate electricity?

The kinetic energy of the neutrons is absorbed by the blanket, causing it to heat up. The heat energy is collected by the coolant (water, helium or Li-Pb eutectic) flowing through the blanket and, in a fusion power plant, this energy will be used to generate electricity by conventional methods.

How is electricity produced from fission?

The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine. As the turbine blades turn, they drive generators that make electricity.

Why is fusion a better energy source than fission?

Fusion offers an appealing opportunity, since fusion creates less radioactive material than fission and has a nearly unlimited fuel supply. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
