How much more powerful is fusion than fission?
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).
Does Fusion produce more energy than fission?
Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission.
Can 2 hydrogen make helium?
Fusion reactions occur when two nuclei come together to form one atom. The reaction that happens in the sun fuses two Hydrogen atoms together to produce Helium. It looks like this in a very simplified way: H + H → He + ENERGY. This energy can be calculated by the famous Einstein equation, E = mc2.
How much energy is released in a fusion reaction?
With current technology, the reaction most readily feasible is between the nuclei of the two heavy forms (isotopes) of hydrogen – deuterium (D) and tritium (T). Each D-T fusion event releases 17.6 MeV (2.8 x 10-12 joule, compared with 200 MeV for a U-235 fission and 3-4 MeV for D-D fusion).
Why higher temperature is required for fusion?
High temperature gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons. Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core). At these temperatures, hydrogen is a plasma, not a gas.
Does nuclear fusion occur naturally?
Fusion reactions occur naturally in stars like our sun, where two hydrogen nuclei fuse together under high temperatures and pressure to form a nucleus of helium. Energy is released as electromagnetic radiation such as light, infra-red radiation and ultra violet radiation , which then travels through space.
Why can’t fusion occur on Earth?
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.
What are the pros and cons of fusion?
