It's purpose is to slow down fast neutrons that maybe present in the reactor.

A nuclear reactor requires the neutrons released from one reaction to trigger the fission of other nuclei. Control rods are required to absorb some of these neutrons so as to prevent a runaway chain reaction.
Nuclear reactors contain rods made of materials which will absorb neutrons. This reduced the cascade of neutrons which are responsible for the chain reaction.

We see the use of control rods in a reactor to absorb neutrons. These rods are often made of boron.

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.

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.
Sorry, in any real nuclear reactor every control rod probably absorbs many moles of neutrons per second while the reactor is operating.
One of the primary functions of a nuclear reactor is to maintain a chain reaction. Also, nuclear reactors are meant to provide a steady flow of neutrons.
Yes, it is the main moderator function in what is called "thermal nuclear reactors"
