A meltdown of the reactor core would occur if

B) too much coolant was lost.
C) the proportion of uranium-238 was too high.
D) the containment building developed an air leak.
E) a meltdown is now longer possible.

Question

Quizplus · Accepted Answer

If too much coolant is lost, the temperature in the reactor core would increase, leading to the fuel rods melting and a possible meltdown of the reactor. Control rods are used to slow down or stop the nuclear reaction, while the proportion of uranium-238 does not directly impact the likelihood of a meltdown. A air leak in the containment building would not necessarily lead to a meltdown, and the statement "a meltdown is no longer possible" is not accurate as the risk of a meltdown always exists.
