Absorb neutrons. Examples are boron and cadmium
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.
Fission in a power plant is controlled by using control rods made of materials like boron or cadmium that absorb neutrons, slowing down or stopping the chain reaction. By adjusting the position of these control rods, operators can regulate the rate of fission, maintaining a stable and controlled nuclear reaction to generate heat for electricity production.
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.
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.

It is a device where a controlled nuclear fission chain reaction occurs.

A runaway chain reaction.It is called super criticality, with KEffective > 1.When one fission reaction instigates more than one or more fission reactions it is called a Chain Reaction.KEffective is the neutron multiplication factor which is an indication of whether a reaction is stable (=1), increasing (>1), or decreasing (
The first time a fission chain reaction was produced was in 1942

A controlled nuclear chain reaction produces heat, driving steam turbines to produce energy.
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.
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
In a chain reaction, each fission reaction must produce at least one additional fission reaction to sustain the reaction. This is necessary to achieve a self-sustaining nuclear reaction where each fission event leads to more fission events, releasing energy in the process. Without this multiplication of fission reactions, the chain reaction would not be able to continue and sustain itself.
Yes, a chain reaction is all fission, just out-of-control fission. Usually, fission creates 2 neutrons per decay, but it is controlled by the fact that lots of neutrons get absorbed by U-238, which doesn't fission, unlike U-235, which does, and by the control rods, which also absorb lots of neutrons. But if these fail to contain the outbreak of neutrons, and the fail safes (which usually just drop the control rods totally into the reactor, stopping any chain reaction) fail, then an exponentially accelerating chain fission reaction can start, and once it starts, it's pretty much impossible to stop.
