The control rods in a nuclear reactor are simply neutron absorbers which can be raised or lowered, this enables the reactor to be maintained at criticality with the chain reaction proceeding at a steady rate. The reactor loses reactivity between refuellings which are probably every two years, so the control rods have to be slowly withdrawn to compensate. They are also fully inserted very quickly should the safety instruments require it, and the reactor then stays shutdown. (Reactor scram or trip)

How does the control rod affect the rate of reaction in the nuclear reactor?
A control rod is made of a neutron absorbing material. Boron is common. When the control rod is withdrawn (pulled out) of the reactor, the fission reaction rate increases. When that control rod is inserted, the reaction rate decreases. There are other factors that control the reaction rate, but the rods can be considered as the way to start up or shut down the reactor by pulling or inserting them.
Is a control rod in nuclear reactor a hollow tube?
Varies. A hollow control rod can act as a "neutron trap." The moderator in the hollow center helps slow the fast neutrons into the thermal region for increased absorption by the surrounding absorbing material such as Boron.
Is a rod and a link the same thing?
I would say the term Control Rod and Control Link are the same. Fixed controls can be designed with different types of rods or tubes and different types of joints where they connect. The term "link" usually describe the entire control mechanism. This could include bell cranks that transmit rotational motion. A rod end is usually a solid steel fitting that has a mono-ball bearing and this rod end is fitted into a hollow tube. Some hollow links are just flattened and hole drilled in it to made a swivel joint. But they still could either be called a rod or link.
What is the abbreviation SCRAM standing for in nuclear reactors?
This Abbreviation SCRAM stands for Safety Control Rod Axe Man. The very early nuclear reactors were equipped with a safety control rod that is kept high above and away from the reactor core. This safety control rod was attached to a rope passing over a wheel and going down where the end of the rope is fixed at a lower point. Then a man with axe is always keeping alert and watching the reactor safe operation. In case of emergency, he cuts the rope with the axe and the safety control rod drops by gravity inside the reactor core and stops the nuclear chain fission reaction and consequently stops reactor operation.
What is the purpose of a diaphragm on a light microscope?
you can control it to adjust the amount of light
What is the purpose of the rod that came in my decanter?
The rod aids in the decanting process. That is the purpose of the rod.
What is the purpose of boron in nuclear reactors?
Boron is used inside a nuclear reactor inside a control rod which is used to 'soak' up the neutrons inside the nuclear reactor, a control rod can be used to control the rate of fission inside a nuclear reactor.
What is the purpose of a panhard rod?
The purpose of the Panhard Rod is to take up lateral forces between the axle and body thus removing load from the radius arms.
What is the purpose of the connecting rod?
it connects the piston to the crankshaft
What is the purpose of the NHRA?
The purpose of the NHRA is to promote the sport of hot rod racing. They advertise and do news releases about the sport to generate national interest in hot rod racing.
