Question

Which one of the following statements is not true about nuclear energy generation in a nuclear reactor?

• A. Energy is obtained by a process called nuclear fission.
• B. The nucleus of Uranium is bombarded with high energy neutrons.
• C. A chain reaction is set in the process.
• D. In this process a tremendous amount of energy is released at a controlled rate.

Answer 1

The correct option is B

The nucleus of Uranium is bombarded with high energy neutrons.

Nuclear reactor:

1. The nucleus of Uranium is bombarded with low-energy neutrons, not with high-energy neutrons.
2. Nuclear fission – It is defined as the splitting of a heavy nucleus into two lighter or daughter nuclei through a nuclear reaction.
3. The heavy nucleus (such as uranium, and plutonium thorium) is bombarded with low-energy neutrons, which results in the production of a high amount of energy.
4. Nuclear reactors are the heart of a nuclear power plant, which uses uranium as a nuclear fuel.
5. They regulate and control nuclear chain reactions that produce heat through the physical process known as fission. And, this heat is used to make steam that spins a turbine to create electricity.

Hence, Option(B) is correct.
