Question

guided practice
at times of high electricity demand, what would you expect to be happening at a nuclear reactor facility?
a. more u-238 is consumed.
b. water levels are lowered.
c. fuel rods are raised.
d. control rods are raised.

Explanation:

Control rods absorb neutrons to slow nuclear fission. Raising them reduces neutron absorption, increasing fission rate and power output to meet high electricity demand. U-238 is not the primary fissionable fuel for power production; fuel rods are not raised to adjust output; water levels are not lowered for this purpose.

Answer:

D. Control rods are raised.
