Nuclear reactors are controlled by changing the geometry of the fuel rods to slow down the reaction, dropping them into moderators, or removing them from the hot part of the reactor.
The old phrase (from my day) was "ax the mandrel, she's running HOT!" meaning drop all the fuel rods into the moderator structure.
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
A controlled nuclear reaction is one in which the average number of reactions per second does not increase.
Yes. Nuclear power plants and nuclear powered ships and submarines use controlled fission reactions.
The place where controlled nuclear fission reactions take place is called a nuclear reactor. In a nuclear reactor, uranium atoms are split in a controlled manner to produce heat energy, which is used to generate electricity.
Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).

Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
Reactions that involve nuclei, called nuclear reactions, result in a tremendous amount of energy. Two types are fission and fusion.
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
we will start with this statement cadmium rods have the property to absorb nutrons now we know that for nuclear reactions it is necessary for the neutrons to strike the nucleus of the atom and thus with the help of cadmium rods we can control the number of neutrons striking the nucleus and we can control our nuclear reactions
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
No, a nuclear reactor cannot detonate like a nuclear bomb. Nuclear reactors use controlled fission reactions to generate heat for electricity, while nuclear bombs use uncontrolled chain reactions to create an explosion. The design and purpose of a reactor prevent it from causing a nuclear explosion.
