Since the continued chain reaction of a nuclear fission reactor depends upon at least one neutron from each fission being absorbed by another fissionable nucleus, the reaction can be controlled by using control rods of material which absorbs neutrons. Cadmium and boron are strong neutron absorbers and are the most common materials used in control rods. A typical neutron absorption reaction in boron is In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by- products which absorb neutrons build up. To keep the chain reaction going, the control rods must be withdrawn further. At some point, the chain reaction cannot be maintained and the fuel must be replenished
What else can I help you with?
Mechanism and container for controlled fission is called?
The mechanism for controlled fission is nuclear reactors, which utilize a controlled chain reaction to generate heat. The container used to house this process is typically a reactor core, which contains the fuel, control rods, and coolant necessary for maintaining the fission reaction at a steady rate.
The chain reaction in a nuclear reactor is controlled by inserting what?
Control rods, made of materials like boron or cadmium, are inserted into the reactor core to absorb excess neutrons and regulate the nuclear chain reaction. By adjusting the position of these control rods, operators can control the rate of fission reactions and manage the amount of heat and energy produced in the reactor.
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 do you control a chain reaction?
A chain reaction can be controlled by regulating the rate at which neutrons are produced and absorbed in the reaction. This can be achieved by controlling the amount of fuel and moderator, as well as using control rods to absorb excess neutrons and adjust the reactor's power level. Additionally, designing the reactor with safety features, such as automatic shutdown systems, can help prevent the chain reaction from getting out of control.
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.
What is the meaning of nuclear reactor?
It is a device where a controlled nuclear fission chain reaction occurs.
What is a device that harness a controlled nuclear chain reaction to produce useful energy?
A nuclear reactor will do what is asked here. Use the link below to the related question about what a nuclear reactor is.
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 must happen for nuclear reactor to make electricity?
a chain reaction
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.
Mechanism and container for controlled fission is called?
The mechanism for controlled fission is nuclear reactors, which utilize a controlled chain reaction to generate heat. The container used to house this process is typically a reactor core, which contains the fuel, control rods, and coolant necessary for maintaining the fission reaction at a steady rate.
How is a chain reaction in a nuclear reactor controlled?
A chain reaction in a nuclear reactor is controlled by inserting control rods made of materials like boron or cadmium into the reactor core. These control rods absorb neutrons and help regulate the rate of the chain reaction by adjusting the number of neutrons available to continue the reaction. By raising or lowering the control rods, operators can fine-tune the reaction to maintain desired power levels.
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.
Is power reactor a thermal reactor?
Yes, a power reactor is a type of thermal reactor. Power reactors use nuclear fission to produce heat, which is then used to generate electricity. The heat generated in the reactor comes from the controlled chain reaction of nuclear fission, making it a thermal reactor.
What control the chain reaction in a nuclear reactor?
The chain reaction in a nuclear reactor is controlled by inserting control rods made of materials like boron or cadmium into the reactor core. These control rods absorb neutrons and help regulate the rate of the chain reaction by adjusting the number of neutrons available for fission. Moving the control rods in or out of the core allows operators to control the power level and ultimately, the reaction itself.
The chain reaction in a nuclear reactor is controlled by inserting what?
Control rods, made of materials like boron or cadmium, are inserted into the reactor core to absorb excess neutrons and regulate the nuclear chain reaction. By adjusting the position of these control rods, operators can control the rate of fission reactions and manage the amount of heat and energy produced in the reactor.
What happens in a nuclear chain reaction and how does it contribute to the release of energy in a nuclear reactor?
In a nuclear chain reaction, the splitting of atomic nuclei releases energy in the form of heat. This process is controlled in a nuclear reactor to generate electricity. The chain reaction is sustained by the release of neutrons from the splitting of nuclei, which then go on to split more nuclei, creating a continuous cycle of energy release.
