A loss-of-coolant accident is very dangerous because
A)without the surrounding water as a moderator,the fission reaction would turn into a fusion reaction.
B)without the surrounding water as a moderator,the fission reaction would increase in rate.
C)the fuel core could overheat from radioactive decay and lead to a meltdown.
D)the leaking coolant would quickly spread highly radioactive material over a large region.

Question

Quizplus · Accepted Answer

A loss-of-coolant accident can cause the fuel core to overheat from radioactive decay, which can lead to a meltdown. This can release dangerous amounts of radioactive material into the environment. While options A and B are incorrect as a loss of coolant would not cause a fusion reaction nor increase the rate of fission, option D is partially correct as a loss of coolant can result in the spread of highly radioactive material, but the coolant itself is not radioactive.
