What is meaning of nuclear energy?

• what is meaning of nuclear delay and energy?

• Answer:

  In general, nuclear energy is the energy that occurs as a result of nuclear reactions (atomic reactions, such as when one atom splits into 2). We usually think of it as energy released in the processes of either nuclear fission or nuclear fusion. In nuclear fission, the nuclei of atoms are split, causing energy to be released. The atomic bomb and nuclear reactors work by fission. In nuclear fusion, the nuclei of atoms are joined together, or fused. This happens only under very hot conditions. The Sun, like all other stars, creates heat and light through nuclear fusion. In the Sun, hydrogen nuclei fuse to make helium.
