In a nuclear power plant fission reactions are controlled by inserting what?
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.
When and where did the first controlled nuclear reactions take place?
Chicago, 1942
Is the nuclear reaction that takes place in a nuclear electrical generating plant exothermic?
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.
Why does nuclear fission take place all through the world?
Not all countries have petrol, methane or coal; nuclear fission is a long term alternative.
How are nuclear fission and nuclear fusion are similar?
They are both nuclear reactions. That's just about it. Other than that they are completely different. Fission is the nuclear reaction when two atoms smash the living soul out of each other and split apart, releasing nuclear energy. The other, fusion, involves the same things as fission, expect that extreme heat and pressure is required for it to happen. Instead of splitting each other apart nuclear fusion fuses atoms together into another compound/element, while releasing about 10 times as much energy as nuclear fission.
What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
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.

What are Controlled nuclear chain reactions?
Those reactions that take place in functioning nuclear reactors (i.e not Chernobyl or Fukushima when the accidents happened).
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)

Is there a place other then the Sun that nuclear reaction happens?
Yes - all the millions of other stars in the Universe, where fusion occurs. Also of course fission reactions in all nuclear reactors on earth
What is the chemical equation for the nuclear reactions that take place in Nuclear Reactors?
It is a set of nuclear equations, not chemical equations. No there are too many of them to write, however they can be summarized by the equation:U235 + n --> light fission product + heavy fission product + x nWhere x varies from 2 to 5 or 6.The mass of the light fission product varies from about 70 to about 115.The mass of the heavy fission product varies from about 115 to about 160.
How could you increase the rate of fission reactions?
Fission does not respond to changes in temperature and pressure like chemical reactions do. In a nuclear reactor, the fission chain reaction can be sped up by removing rods of cadmium, which absorb neutrons. These are in place to prevent the reaction from occurring too quickly. Remove them, and the chain reaction may proceed out of control.
Part of power plant where fission takes place?
In a nuclear power plant, fission takes place in the core.
Can fission happen on earth?
Yes, all natural radiation (in the rocks) is a result of fission (but this fission is not part of a chain reaction like in a fission bomb). However, it is theoretically possible for natural processes to concentrate radioactive elements (uranium) to the extent where a natural nuclear fission reactor (a chain reaction like in a nuclear power plant) will form. Oklo in in Gabon is the only known location for this to have happened and consists of 16 sites at which self-sustaining nuclear fission reactions took place approximately 1.7 billion years ago.
What type of reaction take place in a nuclear reactor?
Nuclear fission, not to be confused with fusion.
