Question

how is the working of nuclear reactor of a power plant shut down in emergency ​

Answer 1

Answer:

Emergency Shutdown – SCRAM.

Explanation:

A reactor “SCRAM” (or “reactor trip”) is the rapid insertion or fall of the control rods into the core to stop the fission chain reaction. It is a key safety function of each nuclear reactor and usually does not need any power supply, since control rods fall only by gravitational force.
