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.

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.
nuclear energy
Nuclear energy typically refers to fission, where atoms are split to release energy. Fusion energy involves merging atoms to release energy, mimicking the process that powers the sun. Fusion has the potential to generate more energy and produce less waste compared to fission.
Nuclear binding energy is released mostly as heat energy.
When nuclear fission occurs, energy is conserved through the process of splitting an atom's nucleus, releasing a large amount of energy in the form of heat and radiation. This energy can be harnessed to generate electricity in nuclear power plants.
Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
Nuclear fission is a type of nuclear reaction that converts nuclear energy into thermal energy (heat), which can then be used to generate mechanical energy (such as electricity). So, fission nuclear energy originates as nuclear energy and can be converted into mechanical energy.
The heat released by nuclear fission is transformed in electrical energy.
Nuclear energy is not related to the small particles that make up an object. It is derived from the nucleus of an atom through processes like nuclear fission or fusion.
The energy released is nuclear energy.
Nuclear fission releases energy in the form of heat, which can be converted into electricity.
Sort of. That's a common explanation for what happens in a nuclear reaction. But technically, both matter and energy are conserved - there is no more or less matter after the reaction, than before the reaction. Therefore, in such cases there is no matter-to-energy conversion. Read the Wikipedia article on "Mass deficit" or "Binding energy" for a more detailed explanation. There's no sort of about it. The meaning of Einstein's equation (E = mc2) is that matter and energy are interconvertible, and this happens all the time. What is conserved is mass-energy. Mass and energy are not conserved separately.
In a nuclear fission reaction, the energy comes from the splitting of atomic nuclei.
nuclear fission
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.
