The difference between a nuclear reactor and atomic bomb is that _________.


A
no chain reaction takes place in nuclear reactor
loader
B
the chain reaction in nuclear reactor is controlled
loader
C
the chain reaction in nuclear reactor is not controlled
loader
D
no chain reaction takes place in atomic bomb while it takes place in nuclear reactor
loader

Solution

The correct option is B the chain reaction in nuclear reactor is controlled

The difference between a nuclear reactor and atomic bomb is that the chain reaction in nuclear reactor is controlled.

A nuclear reactor works by using the energy that is released when the nucleus of a heavy atom splits. That process is called fission. In reactors, fission occurs when uranium atoms are hit by slow-moving neutrons. Absorbing these excess neutrons sometimes causes the atoms to break apart.

In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by-products which absorb neutrons build up.
