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.
(B) The nucleus of Uranium is bombarded with high energy neutrons.
Explanation
The nucleus of Uranium is bombarded with low-energy neutrons, not with high-energy neutrons.
Nuclear fission - It is defined as the splitting of a heavy nucleus into two lighter or daughter nuclei through a nuclear reaction. The heavy nucleus (such as uranium, plutonium thorium) is bombarded with low-energy neutrons, which results in the production of a high amount of energy.
Nuclear reactors are the heart of a nuclear power plant, which uses uranium as a nuclear fuel. 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.
