Question 26 • Physical Science

What is the best way for the power plant manager to modify the reactor to meet the demand for electricity?

Answer
A
raise the control rods so that fewer neutrons are absorbed and more can split uranium atoms
B
lower the control rods, which will absorb more neutrons before they can split atoms
C
remove some of the fuel rods, which will leave more room for additional neutrons to split atoms
D
add additional fuel rods to generate additional neutrons to split uranium atoms

Explanation

To produce more electricity, the reactor needs to increase its rate of fission. Raising the control rods means they absorb fewer neutrons, leaving more neutrons available to split uranium atoms and sustain the chain reaction. So the best choice is to raise the control rods so that fewer neutrons are absorbed.
