Question

Match the following:

List-I Nuclear reactor component	List-II Substance used
$\left(A\right)$ Moderator	$\left(i\right)$ Uranium
$\left(B\right)$ Control rods	$\left(ii\right)$ Graphite
$\left(C\right)$ Fuel rods	$\left(iii\right)$ Boron
$\left(D\right)$ Coolant	$\left(iv\right)$ Lead
	$\left(v\right)$ Sodium

• A. $A-ii,B-i,C-iii,D-v$
• B. $A-ii,B-iii,C-i,D-v$
• C. $A-iii,B-ii,C-i,D-v$
• D. $A-iii,B-iv,C-i,D-ii$
• E. $A-iv,B-iii,C-ii,D-i$

Answer 1

The correct option is B $A-ii,B-iii,C-i,D-v$

Graphite$⟶$carbon rod moderation.

Boron$⟶$control rods to control nuclear reaction.

Uranium$⟶$main active material, for fuel rods.

Coolant$⟶$ sodium sheets.
