What is the name of the reaction that occurs in a nuclear reactors core?
The main reaction that occurs in a nuclear reactor core is nuclear fission. In this reaction, the nucleus of an atom is split into smaller parts, releasing large amounts of energy in the form of heat. This heat is then used to generate electricity in the reactor.
What is the process where the nucleus of an atom splits into smaller parts in a reactor?
The process you are referring to is nuclear fission. In nuclear fission, the nucleus of an atom is split into smaller parts by bombarding it with neutrons. This process releases a large amount of energy and more neutrons, which can go on to split other nuclei in a chain reaction.
Where does the energy of a nuclear reactor come from?
The energy in a nuclear reactor comes from nuclear reactions, specifically fission reactions where the nucleus of an atom is split into smaller parts. This process releases a large amount of energy in the form of heat, which is then used to produce steam to turn turbines and generate electricity.
What parts of an atom are used in Nuclear Fission?
During nuclear fission the atomic nucleus is splitted.
Fission and fusion are parts of what form of energy?
Nuclear energy.
What is splitting of atomic nuclei?
Splitting of atomic nuclei, also known as nuclear fission, is a nuclear reaction in which the nucleus of an atom is split into smaller parts. This process releases a significant amount of energy in the form of heat and radiation. Nuclear fission is used in nuclear power plants and nuclear weapons.
How does uranium fuel get heated in a nuclear reactor?
Fuel in a nuclear reactor is heated by fission reactions. In fission, fuel atoms absorb a neutron, become unstable, and "split apart" into a two approximately equal parts. These parts are called fission fragments, and they come away from the fission event with tremendous kinetic (mechanical) energy. As this happens in a fuel element, the atomic nuclei can travel only a tiny distance before slamming into nearby atoms. This activity is extremely violent on the atomic scale, and it generates a lot of thermal energy (heat). The heat will get fuel element very hot, and that thermal energy will be collected and carried away by the primary coolant in the reactor.
What parts of a nuclear reactor must be removed and replaced periodically?
fuel rods
Does the water used to cool a nuclear reactor get contaminated?
In a properly operating nuclear reactor, water used to cool the reactor is not contaminated. This water, called primary coolant, is quite pure. And after shutdown and cooldown, the water has little radiation in it. But if the reactor has some malfunction that overheats the fuel, fuel elements can rupture or melt (a meltdown) and fission products, which are hightly radioactive, can be released into the coolant (the water). The water is then contaminated.
Is used in nuclear fission?
all you need in nuclear fission is a large element (235Uranium) and a neutron, the neutron goes into the Uranium causeing it to split into smaller parts grapes.
When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?
In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).
How does nuclear fission release energy?
Nuclear fission releases energy when the nucleus of an atom is split into smaller parts, releasing a large amount of energy in the form of heat and radiation.
