Question 9

In a Pressurized Water Reactor (PWR), which of the following statements accurately describes the primary function of the control rods and the moderator material?

Accepted Answer

B. Control rods absorb excess thermal neutrons to regulate the chain reaction, while the moderator slows down fast neutrons to thermal energies. — Control rods, typically made of neutron-absorbing materials like cadmium or boron, are used to absorb excess thermal neutrons, thereby regulating the rate of the nuclear chain reaction. The moderator material, such as heavy water or graphite, slows down the high-energy (fast) neutrons released during fission to lower (thermal) energies, increasing the probability of them being absorbed by fissile nuclei and sustaining the chain reaction.

Answer

A. Control rods absorb fast neutrons to slow them down, while the moderator absorbs excess thermal neutrons.

Answer

C. Control rods reflect neutrons back into the core, while the moderator removes fission products.

Answer

D. Control rods increase the rate of fission, while the moderator cools the reactor core.
