A nucleus which on absorbing a neutron becomes unstable and consequently splits. This happens with U-235 and Pu-239, which are the most common examples.

What is the place where controlled nuclear fission reactions take place?

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.


Why does nuclear fission take place all through the world?

Nuclear fission takes place around the world because it is used in nuclear power plants to generate electricity. The splitting of atoms in fission reactions releases energy in the form of heat, which is used to produce electricity through steam turbines. This method provides a reliable and low-carbon source of power for many countries.


Where do nuclear fission reactions often take place, and what are the key factors that contribute to their occurrence in that location?

Nuclear fission reactions often take place in nuclear reactors. The key factors that contribute to their occurrence in that location include the presence of fissile materials such as uranium-235 or plutonium-239, control rods to regulate the reaction, and a moderator to slow down the neutrons.


What is a fission where does it take place in the sun?

Nuclear fission is the splitting of the nucleus of an element, it only happens to certain ones, most often Uranium 235 but also Plutonium 239. It does not take place in the sun at all, the sun is powered by nuclear fusion which is the joining together of hydrogen nuclei to form helium.


The part of a nuclear reactor in which the fuel is located is called the?

The part of a nuclear reactor in which the fuel is located is called the core. This is where the nuclear fission reactions take place, producing heat that is used to generate electricity.


Do chain reaction takes place in nuclear reactor?

Yes, chain reactions take place in nuclear reactors. In a nuclear reactor, the chain reaction involves the splitting of uranium atoms (fission) which releases energy and more neutrons, leading to further fission reactions. Control rods are used to regulate and maintain the chain reaction at a steady rate.


What type of reaction take place in a nuclear reactor?

Nuclear fission, not to be confused with fusion.


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.


When does fission take place in power plant?

Fission takes place in a nuclear power plant continuously to generate heat by splitting uranium atoms in a controlled manner, producing energy. This heat is used to produce steam, which drives a turbine to generate electricity.


How does the sun produce enagy?

The energy produced in the sun is liberated in the form of heat and light. The reaction going on in the sun is known as Nuclear Fusion and Nuclear Fission. Both processes take place simultaneously.


Can fission take place in the nucleus of hydrogen atom?

No, it cannot. Fission is the "splitting" of an atom, and a hydrogen atom will not fission. Some hydrogen atoms have a neutron stuck to the proton in their nucleus. Some even have two neutrons stuck to that proton. These neutrons can be "knocked loose" in something like a nuclear chair reaction in a weapon. The neutrons then can contribute to the building of the nuclear chain reaction. But fission doesn't happen to hydrogen.


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)
