Question

Draw the diagram of a nuclear power plant and label the following parts.
(a) Control rods
(b) Radiation shield.

Answer 1

Control Rods:These rods absorb neutrons and stop the chain reaction to proceed further. These are made up of steel containing a high percentage of material like cadmium or boron which can absorb neutrons.
Shielding: Shielding prevents radiations to reach outside the reactor and protects the personnel associated with the operations. Lead blocks and concrete enclosure that is strong enough of several meters thickness are used for shielding.
