Maelezo
In a controlled thermal fission reactor, control rods are used to absorb excess neutrons and thus control the rate of the nuclear reaction. They do not affect the speed of the neutrons released on fission. The speed of the neutrons is determined by the nature of the fission process itself, not by the control rods.
