The correct statement about nuclear fission from the options provided is:

Nuclear fission takes place in the nucleus of atoms.

This is because nuclear fission is a process in which the nucleus of an atom splits into smaller parts (fission fragments), releasing a significant amount of energy in the process. The other statements are incorrect:

  • Nuclear fission releases a large amount of energy, not a small amount.
  • It is used to generate heat, which is then used to produce steam for electricity generation in nuclear power plants, not just to generate water.
  • The fuel for nuclear fission typically includes isotopes like Uranium-235 or Plutonium-239, not helium.

So, the only correct answer is the second option.
