slow down the secondary neutrons.

protect the walls of the reactor from radiation damage.

protect the fuel element from coming in contact with the coolant.

Detailed explanation-1: -A layer, or layers, of high-density material located within a reactor pressure vessel or between the vessel and the biological shield to reduce radiation heating in the vessel and the biological shield.
Detailed explanation-2: -Radiation shielding is a protective shield that is inserted betweeen a source of ionising radiation and the object to protect to reduce the amount of damage that can happen to delicate or biological materials, particularly during transport.
Detailed explanation-3: -Thermal shielding is applied for protection of radiation heat, where the shield must keep the heat losses to the wall low. This is the main function in tool machines. In component applications, water-cooled shields can be applied to cool the substrate and as such to enable an increased deposition rate.
Detailed explanation-4: -The purpose of shielding is to give protection from the deadly rays as wall as neutron given off by the process of fission with the reactor. A good shielding system absorbs radiations before they are emitted to the surroundings.
