Neutrons are very important in the fission of uranium, the manufacture of the artificial isotope plutonium-239, and in the fission of plutonium-239. The function of the control rods and moderators in a nuclear power plant are very important in the processes mentioned. Select the purpose for control rods (from answers A - D) and for moderators (from answers E - H).
Question options:
A) slow the neutrons down so they can cause fission.
B) absorb the heat produced so that it can be carried to an external turbine.
C) absorb neutrons to control the amount of fission that is occuring.
D) provide the fuel needed for fission to occur.
E) carry the heat produced from the fission reactions to an external turbine.
F) absorb neutrons and thereby control the fission reactions.
G) protect the workers and the environment from radiation.
H) slow down the neutrons produced from the fission reactions so that they can be absorbed by more fuel.
