Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:A nuclear power reactor is a system designed to sustain a fission chain reaction and extract useful energy.
Statement II:Light water reactors use ordinary water as the moderator.
ABoth Statement I and Statement II are correct ✓ Correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct
Correct answer: (A) Both Statement I and Statement II are correct
Explanation
A nuclear power reactor sustains a controlled fission chain reaction to extract useful energy.
Statement 1 is correct because its core is engineered to keep the reaction steady and yield heat.
That heat raises steam, which drives turbines to generate electricity.
Statement 2 is correct because light water reactors use ordinary water as the moderator.
The water slows fast neutrons and also carries heat away as the coolant.
Heavy water reactors instead use deuterium oxide, allowing the use of natural uranium fuel.
