Control rods made of cadmium or boron moderate the fission reactions in nuclear power plants.Which of the following best describes how control rods function?
A)Control rods absorb the high heat that is produced from the fission reactions,preventing overheating from occurring.
B)Control rods absorb some of the fast moving neutrons that are produced in the fission reactions,preventing their initiation of other fission reactions.
C)Control rods absorb the steam produced when the water is heated to a high temperature,preventing the generation of electricity.
D)Control rods absorb gamma rays that are responsible for initiating a chain reaction.
E)Control rods act as a catalyst for the reverse of the fission reaction,preventing the fission reaction from continuing.
