what do you mean by nuclear energy ?

the set up used for generating electricity from the energy released in the nuclear fission reaction is called nuclear power plant .

n 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

Nuclear means 'anything that is related to the nucleus of the atom'.

Nuclear energy means energy of the nucleus.

 Nuclear energy: It is the energy released by nucleus during a nuclear reaction i.e. during fission or a fusion.

Energy released in a fission reaction:

₉₂ U²³⁵ + 1neutron ===> ₅₆Ba¹⁴² + ₃₆Kr⁹² + 2n + Energy

Energy released in a fusion reaction:

₁ H² + ₁H³ ===> ₂He⁴ + 1neutron + Energy
