Why would a chain-reaction control substance that loses neutron-absorbing power as its temperature increases be dangerous?
A)Because it would start to emit protons.
B)Neutrons would start to collide with each other and that would be bad.
C)It would be unusually radioactive.
D)Unhindered neutrons would cause a meltdown.

Question

Quizplus · Accepted Answer

A chain reaction control substance is used to regulate the rate of fission in a nuclear reactor. If the substance loses its neutron-absorbing power as its temperature increases, it would become less effective in controlling the rate of fission. This could lead to an increase in the number of unhindered neutrons, which could in turn cause a nuclear meltdown.
