Question 1

The moderator in a nuclear reactor is used to slow down fast-moving neutrons. This is important because:

A

slow-moving neutrons are more likely to cause further fission reactions in uranium-235 (235U^{235}\text{U}235U)

B

slow-moving neutrons are easily absorbed by the control rods

C

slowing down neutrons reduces the temperature of the reactor

D

slow-moving neutrons convert uranium into more stable elements
