A nuclear reactor generates heat by controlled nuclear fission. Primary coolant carries this heat away to make steam. If a reactor is not cooled, it will overheat. Even if it is shut down immediately, the radioactive fragments of fission in the core will still be undergoing radioactive decay. This will continue to generate a lot of what we call decay heat. This heat can be sufficient to melt the metal that forms the fuel elements if cooling is not maintained, and the result is a nuclear meltdown with various consequences.

What is a dangerous condition caused by overheating inside a nuclear reactor?
A dangerous condition caused by overheating inside a nuclear reactor is called a nuclear meltdown. This occurs when the reactor core is unable to be cooled and may result in a breach of the containment structures, releasing radioactive material into the environment.
What is used in nuclear power stations to cool the reacants down?
Water is commonly used to cool the reactor in nuclear power stations. This water absorbs the heat generated by the nuclear reactions and carries it away, preventing the reactor from overheating. The cooled water is then circulated back to the reactor to continue the cooling process.
Where is the nuclear reactor KAMINI located?
The KAMINI (Kalpakkam Mini) reactor is a Uranium-233 fueled, demineralized light water moderated and cooled, beryllium oxide reflected, low power nuclear research reactor. It is located in the post irradiation examination facility of Radio Metallurgy Laboratory, Indira Gandhi Centre for Atomic Research, Kalpakkam, India. A link is provided to the Wikipedia article.
Is the sun a nuclear fusion reactor?
Yes, the sun is a nuclear fusion reactor.
What starts the nuclear chain reaction in a nuclear reactor?
The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.
What is a dangerous condition caused by overheating inside a nuclear reactor?
A dangerous condition caused by overheating inside a nuclear reactor is called a nuclear meltdown. This occurs when the reactor core is unable to be cooled and may result in a breach of the containment structures, releasing radioactive material into the environment.
Why do nuclear power stations need to be cooled down?
Because, if they aren't, the excess heat will damage the reactor.
What happens to a nuclear reactor when operated below grid frequency 50hz?
The nuclear reactor doesn't care. Only the turbines that spin the generators do.
Which section of a nuclear reactor does nuclear fission occurs?
The fission happens in the fuel, which is usually in fuel rods inside the reactor. The rods are spaced at a particular distance apart and fill the reactor.
What is used in nuclear power stations to cool the reacants down?
Water is commonly used to cool the reactor in nuclear power stations. This water absorbs the heat generated by the nuclear reactions and carries it away, preventing the reactor from overheating. The cooled water is then circulated back to the reactor to continue the cooling process.
What is the Japanese Nuclear Reactor?
A Nuclear Reactor.
How many type of nuclear energy?
Nuclear fission reactors come in various forms, though the principle of using the heat from a nuclear chain reaction is always the same. 1. Pressurised Water Reactor (PWR). 2. Boiling Water Reactor (BWR). 3. Magnox gas cooled reactor (no longer built) 4. Advanced gas cooled reactor (no longer built but still in use in UK). 5. Canadian heavy water reactor (Candu) 6. Russian design of Chernobyl type. I think this covers the most used types for power generation. There are others such as the gas cooled pebble bed reactor, and the fast breeder reactor, that are possible but designs have not been so successful and these have not been adopted commercially.
What Happens if the number of cadmium are less in a nuclear reactor?
Less power will be created.
What happens if nuclear reactor leaks?
If a nuclear reactor leaked you would have to evacuate the area around the plant and you would attempt to stop the leak and probably depending on the severeity level of the situation you may need to 'SCRAM' the reactor.
What is nuclear reactor kinetics?
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
Which material is used as a cladding material in nuclear reactor?
Fuel pellets are typically clad in Zircalloy, if that was your question. Especially in water cooled reactors.
Which section of a nuclear reactor does nuclear fission occur?
Nuclear fission occurs in the reactor core of a nuclear reactor. This is where nuclear fuel, typically uranium, is arranged in such a way that it sustains a chain reaction of splitting atoms, releasing energy in the process.
