Which situation would lead to a meltdown of the reactor core in a nuclear plant?
A) if the containment building develops an air leak
B) if control rods are inserted into the core
C) if the proportion of uranium-238 is too high
D) if too much coolant is lost

Question

Which situation would lead to a meltdown of the reactor core in a nuclear plant? 
A) if the containment building develops an air leak 
B) if control rods are inserted into the core 
C) if the proportion of uranium-238 is too high 
D) if too much coolant is lost

Quizplus · Accepted Answer

If too much coolant is lost, the reactor core can overheat, causing a meltdown. Without the coolant, the fuel rods will continue to heat up and eventually melt, releasing radioactive material into the environment. The other options (air leak, control rods, and uranium-238 proportion) are not directly related to a meltdown of the reactor core.
