What type of reaction happens inside a nuclear plant?
A nuclear chain reaction nuclear fission
What is meant by chain reaction in nuclear reactor?
Basically a chain reaction (nuclear or chemical) is a self sustaining auto-catalytic reaction.In a nuclear reactor it is a neutron chain reaction, where each neutron released in every fission event can trigger another fission event. In a nuclear reactor the excess neutrons must be disposed of, which is the purpose of the control rods so that the reaction can be kept at some desired constant rate.
How is the chain reaction in a nuclear reactor different from one in an atomic bomb?
In a reactor it is controlled and stays at a constant rate. In a bomb it is uncontrolled and rises exponentially until the bomb explodes, terminating it.
A nuclear Chain reaction occurs when?
When excess electrons collide with other nuclei.
What is the krypton problem?
In nuclear reactors, krypton can absorb enough neutrons to slow or stop the chain reaction.
Can the chain reaction of nuclear fission be stopped or controlled?
The chain reaction can be controlled, and it can be stopped. It is controlled in a nuclear power plant, and it is stopped when the plant shuts down, as it does periodically for refueling.
What is the meaning of nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
What is meant by nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
How is a chain reaction in a nuclear reactor controlled?
Nuclear reactors contain rods made of materials which will absorb neutrons. This reduced the cascade of neutrons which are responsible for the chain reaction.
How is the controlled release of nuclear energy in a reactor accomplished?
controlling a chain reaction
What radioactive isotope is generally used to fuel a controlled nuclear chain reaction?
235U with a 5% enrichment of 238U is generally used to fuel a controlled nuclear chain reaction. In a navy nuclear application, such as a submarine, a higher enrichment of 238U is used, around 20%.
The chain reaction in a nuclear reactor is controlled by inserting what?
control rods.
What is the difference in a nuclear power plant and a nuclear bomb?
A nuclear power plant uses a slow, controlled nuclear chain reaction to heat water and generate electricity. A nuclear bomb uses a very rapid uncontrolled nuclear chain reaction in order to generate a massive explosion.
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
What happens if a nuclear chain reaction is not controlled?
The reactor fuel would overheat, melt, and fall apart.
What is the theory behind the process of nuclear power plants?
The controlled nuclear chain reaction process, as developed in 1939 by Leo Szilard and patented, then verified experimentally in 1942 by Enrico Fermi on the CP-1 graphite pile reactor.
