Nuclear power is energy which is produced with the use of a controlled nuclear reaction. Many nations use nuclear power plants to generate electricity for both civilian and military use, and some nations also utilize this type of energy to run parts of their naval fleets, especially submarines.
It canbe released from atoms in two ways: nuclear fusion and nuclear fission.In nuclear fusion, energy is released when atoms are combined or fused together to forma larger atom. This is how the sun produces energy.In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.Nuclearpower plants use nuclear fission to produce electricity. NUCLEAR FUEL-URANIUM The fuel most widely used by nuclear plants for nuclear fission is uranium.nstead,nuclear plants use the heat given off during fission as fuel. Fission takes place inside thereactor of a nuclear power plant. At the center of the reactor is the core, which contains theuranium fuel.The uranium fuel is formed into ceramic pellets.
