A self-amplifying reaction and a nuclear explosion in a nuclear power plant are prevented in large part by
A)the regular addition of uranium-239 to the fuel.
B)control rods that absorb extra neutrons.
C)the production of plutonium-239.
D)fuel rods that absorb tremendous amounts of heat.

Question

Quizplus · Accepted Answer

Control rods that absorb extra neutrons can be inserted into the reactor core to control the rate of the nuclear reaction and prevent a self-amplifying reaction or a nuclear explosion. This is a crucial safety measure in nuclear power plants. The other options, such as adding uranium-239 or producing plutonium-239, are not relevant to preventing self-amplification or explosions. Fuel rods that absorb heat are important for preventing damage to the fuel, but they do not directly prevent self-amplifying reactions or explosions.
