Expert Answer:

Dear Student
Nuclear fission involves the splitting of large atoms, usually uranium (or sometimes plutonium). When large atoms fission they produce two smaller atoms or fission fragments (and a couple of neutrons and lots of energy). The total mass of the products is less than the mass of the original atom. This mass difference is turned into energy in accordance with the Einstein equation E=mc2. Most of the energy appears in the recoil of the fission fragments, and the heat that is generated is considerable. It is that heat that we capture to turn water into steam to generate electricity.
