Fission more or less just happens. We can speed it up by increasing neutron flux, and even control the amount of speed-up by controlling the neutron flux using neutron absorbing materials. However, fusion doesn't occur at anything resembling normal conditions on Earth. We've got to produce tremendous temperatures and pressures to overcome the electrostatic repulsion between hydrogen nuclei and get them close enough together for the residual strong force to take over. When they do, it releases a large amount of energy, and it's hard to confine that. Currently the best I'm aware of that we've managed to do while still controlling the reaction is about 65% of input power (that is: for every 100 watts used heating and pressurizing and containing the thing, 65 watts of power were generated) and that only for an instant, but research is continuing and some people think it's possible.

How is a nuclear fission reaction controlled in nuclear reactor?
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.

Which do you currently use nuclear fusion or fission?
I currently use nuclear fusion.
What is the process where the nucleus of an atom splits into smaller parts in a reactor?
The process you are referring to is nuclear fission. In nuclear fission, the nucleus of an atom is split into smaller parts by bombarding it with neutrons. This process releases a large amount of energy and more neutrons, which can go on to split other nuclei in a chain reaction.
Where does nuclear fusion occur in a nuclear plant?
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.

Does nuclear power plants uses nuclear fusion?
No, they rely on fission. Controlled fusion is the holy grail of nuclear power.
How a fusion reactor would be similar to a fission reactor?

How is a nuclear fission reaction controlled in a nuclear reactor?
A nuclear fission reaction is controlled in a nuclear reactor by using control rods made of materials that absorb neutrons, such as boron or cadmium. By adjusting the position of these control rods within the reactor core, the rate of fission and thus the power output can be regulated. Inserting the control rods absorbs neutrons and reduces the number available for further fission reactions, helping to maintain a steady power level.
What are the three main advantages of a fusion reactor compared to a fission reactor?
Fusion reactors produce less radioactive waste compared to fission reactors. Fusion reactors use abundant sources such as deuterium and lithium for fuel, while fission reactors use limited sources like uranium. Fusion reactions release more energy per unit mass of fuel compared to fission reactions.
What type of power does nuclear fission have?
Fusion power is the power generated by the nuclear fusion processes. Fusion power is a primary area of researc in plasma physics. For example, the sun is a natural fusion reactor.
Is the sun a nuclear fusion reactor?
Yes, the sun is a nuclear fusion reactor.
What is the difference between a bioreactor and nuclear reactor?
A nuclear reactor uses either nuclear fission or nuclear fusion to generate electricity, while bio-reactors use the excretions of many animals to generate electricity.
Is fusion controllable as fission is reactor?
no
How are nuclear reactions that take place in the sun different from the nuclear reactions that take place in a nuclear reactor?
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)

Which do you currently use nuclear fusion or fission?
