Nuclear fusion combines hydrogen atoms into helium atoms. Hydrogen is available from water and helium is an inert gas. When fusion reactors become technologically feasible, we will greatly reduce consumption of limited fossil fuels and production of greenhouse gases.
Fusion reactors will not produce high level nuclear waste.
No, they rely on fission. Controlled fusion is the holy grail of nuclear power.
Nuclear fusion is used only in experimental installations.
Nuclear fusion does not currently occur in nuclear plants. Nuclear plants use nuclear fission, where atoms are split to release energy. Fusion reactions, in which atomic nuclei combine to release energy, are not yet used commercially for electricity generation.
No, nuclear fusion does not directly provide energy to green plants to grow. Green plants rely on photosynthesis, a process that converts sunlight into energy, to grow and produce food. Nuclear fusion is a process that occurs in stars and has the potential to provide a vast source of clean energy for human use.
There is very little similarity between present day power plants which use nuclear fission, and any possible nuclear fusion plant of the future
No, a nuclear power plant producing electricity is an example of nuclear fission, not fusion. In nuclear fission, the nucleus of an atom is split, releasing energy, whereas in nuclear fusion, atomic nuclei combine to release energy.
None of them do.
A nuclear fusion reaction has the potential to produce large amounts of energy, far exceeding current nuclear fission reactions. It is estimated that a single fusion reaction could potentially yield millions of kilowatt-hours of energy. However, practical implementation and scaling of fusion as a viable energy source on a commercial scale is still a significant challenge.
Because no one has been able to produce a continuous fusion reaction so far.
The two isotopes that you are referring to are deuterium (2H) and tritium (3H). When they undergo nuclear fusion, they combine to form a neutron (1n) and helium-4 (4He). This reaction releases energy and is the principle behind nuclear fusion reactions in stars and potentially in future fusion power plants.
Cold fusion is a theoretical nuclear reaction that supposedly occurs at room temperature, while nuclear power plants use controlled nuclear fission reactions to generate heat and produce electricity. Cold fusion has not been reliably demonstrated, while nuclear power plants worldwide successfully use fission to generate a significant portion of electricity.
Nuclear fusion and fission are both processes that involve releasing energy from the nucleus of an atom. They can both produce large amounts of energy and are used in nuclear power plants.
