Nuclear Reactors are based on which of the following phenomenon?
[A] Magnetic confinement of Plasma
[B] Nuclear Fusion
[C] Controlled Nuclear Fission
[D] None of the above



Answer :

Answer:

**C) Controlled Nuclear Fission**

Nuclear reactors operate based on the controlled nuclear fission phenomenon. In a nuclear reactor, heavy atomic nuclei (such as uranium-235 or plutonium-239) are split into smaller nuclei when struck by neutrons, releasing a significant amount of energy in the form of heat. This process is carefully controlled in reactors to maintain a steady rate of fission and to manage the heat generated, which is then used to produce steam and drive turbines for electricity generation.

Here's why the other options are not correct for nuclear reactors:

- **A) Magnetic confinement of Plasma:** This is related to nuclear fusion, not fission. Magnetic confinement is used in experimental fusion reactors like tokamaks and stellarators.

- **B) Nuclear Fusion:** While fusion is a promising source of energy, it is not yet a practical technology for power generation in current nuclear reactors. Fusion involves combining light nuclei to form heavier ones, releasing energy in the process, but this technology is still in the experimental stage.

- **D) None of the above:** This is incorrect as controlled nuclear fission is the basis for nuclear reactors.

Explanation:

Answer:

B . Nuclear Fusion is the best for Nuclear Reactors
