If a nuclear chain reaction is not controlled, it can lead to a runaway reaction with an increase in heat and radiation release beyond safe levels. This can result in a nuclear meltdown, leading to damage to the reactor core and potential release of harmful radioactive materials into the environment.

What is the difference in a nuclear power plant and a nuclear bomb?
A nuclear power plant is designed to generate electricity using controlled nuclear reactions, while a nuclear bomb is designed to release a massive amount of energy in an uncontrolled manner to cause destruction. The reactor in a power plant sustains a controlled chain reaction to produce heat for electricity, whereas a bomb triggers a rapid and uncontrolled chain reaction for explosive power.
What is meant by nuclear reactor?
A nuclear reactor is a device that initiates and controls a nuclear chain reaction, producing heat that is used to generate electricity or for other purposes like propulsion in nuclear submarines. It uses nuclear fuel, such as uranium or plutonium, to sustain the controlled fission reactions that release energy.
What type of reaction happens inside a nuclear power plant?
A nuclear chain reaction nuclear fission
What causes the nuclear reaction to keep going once it has started?
The nuclear reaction in nuclear power plants continues because of a self-sustaining chain reaction. In this process, neutrons produced by fission cause further fission in other uranium or plutonium nuclei, releasing more energy and more neutrons. This chain reaction is controlled and moderated by control rods to maintain a stable and controlled release of energy.
How is the controlled release of nuclear energy in a reactor accomplished?
In a nuclear reactor, controlled release of nuclear energy is achieved through a process called nuclear fission. Uranium atoms are split when struck by neutrons, causing a chain reaction that releases heat energy. This heat is then used to generate steam, which drives turbines to produce electricity.
What is the meaning of nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
What radioactive isotope is generally used to fuel a controlled nuclear chain reaction?
Uranium-235 is the main radioactive isotope used to fuel controlled nuclear chain reactions in nuclear reactors. It undergoes fission when bombarded with neutrons, releasing energy and more neutrons to sustain the chain reaction.
What is the difference in a nuclear power plant and a nuclear bomb?
A nuclear power plant is designed to generate electricity using controlled nuclear reactions, while a nuclear bomb is designed to release a massive amount of energy in an uncontrolled manner to cause destruction. The reactor in a power plant sustains a controlled chain reaction to produce heat for electricity, whereas a bomb triggers a rapid and uncontrolled chain reaction for explosive power.
Can the chain reaction of nuclear fission be stopped or controlled?
Yes, the chain reaction of nuclear fission can be controlled by using control rods made of materials like boron or cadmium that absorb neutrons, thus regulating the rate of fission. Additionally, cooling systems can also be used to control the temperature and prevent the reactor from overheating.
How is the chain reaction in a nuclear reactor different from one in an atomic bomb?
In a nuclear reactor, the chain reaction is controlled to produce a steady flow of energy by regulating the rate of reactions. In an atomic bomb, the chain reaction happens rapidly and uncontrollably, resulting in a massive release of energy in a short period of time, leading to an explosion.
What is meant by nuclear reactor?
A nuclear reactor is a device that initiates and controls a nuclear chain reaction, producing heat that is used to generate electricity or for other purposes like propulsion in nuclear submarines. It uses nuclear fuel, such as uranium or plutonium, to sustain the controlled fission reactions that release energy.
does nuclear fission produce energy?
A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.
What type of reaction happens inside a nuclear power plant?
A nuclear chain reaction nuclear fission
How are nuclear chain reaction to controlled in nuclear power plants?
Nuclear chain reactions in nuclear power plants are controlled by inserting control rods made of materials like boron or cadmium into the reactor core. These control rods absorb neutrons, reducing the number available to sustain the chain reaction. By adjusting the position of the control rods, operators can regulate the reactor's power output.
What causes the nuclear reaction to keep going once it has started?
The nuclear reaction in nuclear power plants continues because of a self-sustaining chain reaction. In this process, neutrons produced by fission cause further fission in other uranium or plutonium nuclei, releasing more energy and more neutrons. This chain reaction is controlled and moderated by control rods to maintain a stable and controlled release of energy.

Uranium atoms are split when struck by neutrons, causing a chain reaction that releases heat energy. This heat is then used to generate steam, which drives turbines to produce electricity.
What is necessary sustain a nuclear chain reaction?
In a chain reaction, neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions.
