Question

1.
The source of energy in nuclear power reactor is:
A. Nuclear fission reaction
B. Exothermic chemical reaction
C. Nuclear fusion reaction
D. Controlled nuclear fission chain reaction ​

Answer 1

Answer:

A) Nuclear fission reaction is correct answer..

Answer 2

Answer:

The Correct Answer would be D. Controlled nuclear fission chain reactions. The source of energy in nuclear power reactor is the controlled nuclear fission chain reactions that take place inside a nuclear reactor.

Explanation:

What is a Nuclear Energy?

Nuclear Energy or Atomic Energy is the energy which is released due to the contractions and relaxations made by atoms and nuclei of different elements. The energy produced here is obtained in a vast amount and is only used for special purposes.

What is Nuclear Fission Chain Reactions?

Nuclear Fission happens when a nuclei with higher atomic mass splits into two or more nuclei of lower atomic mass, releasing a huge amount of energy in the process. When a lot of nuclear fission reactions occur at a same time, at same place (nuclear reactor), it is termed as Nuclear Fission Chain Reaction.
