Solution

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.
