Brakes are to a car as control rods are to a nuclear-fission chain reaction - true or false?

true


How do you control a chain reaction?

control rods


The chain reaction in a nuclear reactor is controlled by inserting what?

control rods.


What is done to keep the nuclear reactor under control?

control rods act like brakes to slow the neutron chain reaction rate in normal operation. the SCRAM system acts in emergencies to completely bring the neutron chain reaction to an instant stop. even with the reactor stopped, the cooling system must operate to prevent overheating from the radioactive decay of the built up fission products.


If you wanted to slow down the chain reaction in a nuclear reactor would you remove or insert the control rods?

In order to slow down the chain reaction in a nuclear reactor, i.e. to reduce KEff, you would insert the control rods.


What control the chain reaction in a nuclear reactor?

The reason a nuclear chain reaction occurs is that one of the by products of a single reaction: the neutrons can start reactions of their own. So how do you stop a chain reaction? Stop these neutrons from causing any more reactions. This is done in nuclear reactors by placing control rods into the reactor core. These control rods are made of elements that can absorb the high energy neutrons without reacting themselves. Therefore, by moving these rods in and out of the reactor, the rate of reaction in a nuclear reactor can be easily controlled.


Do nuclear isotopes stop decaying when control rods are down?

No, it is not correct; only a nuclear chain reaction can be stopped with control rods.


How is a chain reactor controlled?

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 To keep the chain reaction going, the control rods must be withdrawn further.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
