Energy is always conserved. You can neither create nor destroy energy. The same goes for mass. They can only be moved from one frame of reference to another. Fission has nothing to do with it. Ditto for fusion.
One area of "confusion" for many people is Einstein's mass-energy equivalence equation e = mc2. Some people think it means that mass can be converted to energy and vice versa. Nope. Not even close. Mass is energy, and energy is mass. Think about that.
Nuclear energy generated by nuclear fissions of nuclear fuels.
Nuclear energy
this energy is the nuclear energy.
Nuclear energy as we use it now is from nuclear fission. Nuclear fusion is the joining up of nuclei rather than the splitting (fission), but it is not yet available on Earth.
If you're referring to nuclear energy in power generating plants, it is nuclear fission. If you're referring to the nuclear energy in our Sun, it is nuclear fusion.
Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
The heat released by nuclear fission is transformed in electrical energy.
The energy released is nuclear energy.
Nuclear energy generated by nuclear fissions of nuclear fuels.
Nuclear fission.
Nuclear energy
No, nuclear fission is not reversible energy. It is irreversible process.
Nuclear Fission Energy is energy that is produced using fissionable elements. The most common is Uranium. Fission energy involves the fission heating water and turning a turbine, much like coal.
Not precisely. The current technology of nuclear energy gets energy from fission. Fission produces radiation, as well as energy.
In nuclear fission reactors
