Vedclass · Answer

(B) The components of a nuclear reactor are matched as follows:$1$. Moderator: Used to slow down fast neutrons. Graphite is a common moderator.$2$. Control rods: Used to absorb neutrons and control the rate of fission. Boron is commonly used.$3$. Fuel rods: Contain the fissile material. Uranium is the standard fuel.$4$. Coolant: Used to remove heat from the reactor core. Liquid sodium is often used in fast breeder reactors.Therefore,the correct matching is $1-b, 2-c, 3-a, 4-e$.

List-$I$ (Nuclear reactor component)	List-$II$ (Used substance)
$1$. Moderator	$(a)$ Uranium
$2$. Control rods	$(b)$ Graphite
$3$. Fuel rods	$(c)$ Boron
$4$. Coolant	$(d)$ Lead
	$(e)$ Sodium
