In a nuclear reactor the control rods are
WebControl rods are a series of rods that can be quickly inserted into the reactor core to absorb neutrons and rapidly terminate the nuclear reaction. [2] They are typically composed of actinides, lanthanides, transition metals, and boron, [3] in various alloys with structural backing such as steel. WebControl rods in a BWR are inserted from below. Under power they are driven into place with hydraulics. Water from the reactor feed water system is forced into the control rod drive …
