Figure 1 shows a schematic cross-section of a nuclear reactor core during operation.

A schematic diagram of a nuclear reactor core during operation showing fuel rods, control rods, and a moderator.

During an emergency shutdown procedure, known as a SCRAM, the control rods are rapidly and completely inserted into the reactor core.

Explain, with reference to the neutrons produced in fission, how this action stops the nuclear fission chain reaction.
