Question

The nuclear reaction that takes place in a nuclear reactor is

• A. nuclear fusion reaction
• B. controlled fission reaction
• C. uncontrolled fission reaction
• D. none of the above

Answer 1

The correct option is B

controlled fission reaction

Fission reaction:

1. The nuclear reaction that takes place in a nuclear reactor is a controlled fission reaction.
2. These reactions underpin the operation of nuclear reactors.
3. When nuclei with heavy atoms are bombarded with neutrons, they can be divided into several fragments formed by nuclei with lighter atoms, resulting in neutron emission and a large release of energy.
4. This type of nuclear reaction is referred to as a “nuclear fission reaction.”

Hence, Option(B) is correct.
