A nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy.
A nuclear reaction involves changes in the nucleus of an atom, and it is from the atomic nucleus that energy is released in a nuclear reaction.
energy of a reaction will be lost in the form of heat.
It is often stated that mass is transformed to energy. This is wrong, since both mass and energy are conserved in a chemical reaction - or in a nuclear reaction. The Wikipedia article on "binding energy" clarifies this.
Nuclear binding energy is released mostly as heat energy.
Electrical energy, in the triggering and fuzing mechanisms. Chemical energy, in the form of conventional explosives used to trigger the chain reaction. Nuclear energy, in the form of fissionable or fusable nuclear materials.
nuclear fusion
No. Nor can you convert mass into energy. In any reaction - including nuclear reactions - both the amount of mass and the amount of energy remain the same, before and after the reaction. For example, the energy that escapes from a nuclear reaction also has a corresponding mass. On the other hand, the energy existed before the reaction as well, in the form of (nuclear) potential energy.
Nuclear Energy
Nuclear energy is either:fission reaction, orfusion reaction, orradioactive decay

What is the question
Nuclear energy
fusion nuclear reaction followed by fission nuclear reaction
Nuclear fusion refers to a nuclear reaction wherein two light nuclei fuse to form a heavier nucleus. This process releases energy.
We use nuclear fission in nuclear reactors to tap nuclear energy.
A change from one form of matter to another, with the release of large amounts of energy.
