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.
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
I would imagine it is since the goal of an electric plant is to give off energy, and exothermic reactions release entergy. Both fusion and fission, the two major nuclear reactions, are exothermic.
The nuclear reactions in the Sun primarily involve fusion of hydrogen nuclei to form helium, releasing energy in the process. In a nuclear reactor, the reactions typically involve fission of heavy nuclei like uranium or plutonium, releasing energy through splitting these nuclei. The conditions and mechanisms governing the reactions in the Sun and in a nuclear reactor are different due to the vastly varying scales and environments of the two systems.
The only place in which nuclear FUSION takes place is in stars (the sun included), and in the detonation of a hyndrogen bomb. If you are asking about nuclear FISSION (an entirely different process), restate the question.

Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).
The first controlled nuclear reaction took place in 1942 at the University of Chicago. The first nuclear meltdown occurred at the Chernobyl Nuclear Power Plant in 1986, which is 44 years later.
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.
The first controlled nuclear reaction took place in 1942, and the first nuclear meltdown in US history occurred in 1979, marking a span of 37 years between these two events.

The first controlled nuclear reaction occurred on December 2, 1942, while the first nuclear meltdown in U.S. history, which took place at the Three Mile Island plant, occurred on March 28, 1979. This means that approximately 36 years passed between these two events.
Nuclear power plants use controlled nuclear reactions to generate electricity and are not explosive in the same way as nuclear weapons or chemical explosives. While accidents at nuclear power plants can release harmful radiation, the likelihood of a nuclear explosion is extremely low due to safety measures in place.
