Question

Match List-I with List-II.
Choose the correct answer from the options given below:

	List I(components of reactor)		List-II(Function)
A	Uranium	I	The reaction rate can be controlled by it.
B	Moderator	II	Slows down the fast-moving neutrons
C	Control rod	III	Used for fission reaction
D	Coolant	IV	Transfers heat from core to turbine

 

• A. (A)-(III),(B)-(IV),(C)-(I),(D)-(II)
• B. (A)-(III),(B)-(II),(C)-(IV),(D)-(I)
• C. (A)-(III),(B)-(II),(C)-(I),(D)-(IV)
• D. (A)-(II),(B)-(III),(C)-(IV),(D)-(I)

Answer 1

The Correct Option is C

Step 1: Understand the Role of Each Component

Let’s break down the function of each nuclear reactor component:

• Uranium: The fuel for the fission reaction, splitting to release energy.
• Moderator: Slows down neutrons to sustain the chain reaction.
• Control rod: Regulates the reaction by absorbing neutrons.
• Coolant: Transfers heat from the reactor core to generate electricity.

Step 2: Match Components to Functions

• A. Uranium → III. Used for fission reaction: Uranium undergoes fission, making it the fuel for the reaction.
• B. Moderator → II. Slows the fast-moving neutrons: Moderators like graphite or water slow neutrons to sustain fission.
• C. Control rod → I. The reaction rate can be controlled by it: Control rods adjust the reaction by absorbing neutrons.
• D. Coolant → IV. Transfers heat from core to turbine: Coolants like water or gas carry heat to produce electricity.

Step 3: Form the Matching Sequence

Based on the analysis:

• A → III
• B → II
• C → I
• D → IV

The sequence is A-III, B-II, C-I, D-IV.

Step 4: Select the Correct Option

Comparing with the given options:

• Option 1: A-I, B-II, C-IV, D-III → Incorrect
• Option 2: A-II, B-I, C-IV, D-III → Incorrect
• Option 3: A-III, B-II, C-I, D-IV → Correct
• Option 4: A-I, B-III, C-IV, D-II → Incorrect

Final Answer

The correct answer is Option 3: A-III, B-II, C-I, D-IV.
