Describe the energy in nuclear fuel and the way in which it's converted to electrical energy.

Nuclear energy is formed by the splitting of a heavy atom into lighter atom the result of which is the release of energy in the process - this energy is the nuclear energy that binds the nucleons together. With many atoms in a single fuel rod, the energy amounts to millions and billions of orders of magnitude. This energy is released and used to heat water that turns to steam and used to move turbine generators that produce electricity.
