In some reactors, all rods (29 to 100+, depending on reactor size) may insert in as short a time as 2 seconds. The control rods are made of materials that quickly stop the nuclear reaction by absorbing the neutrons (i.e. the materials divert the neutrons from being absorbed or causing fissions in the fuel.
