its converted to energy
It stops at about 0.12 seconds.
The amount of mass lost through nuclear fusion is only 7/10 of 1% of the mass of the four hydrogen nuclei. However, it takes a multitude of reactions for the Sun to produce the amount of energy that it does. Each second, the Sun’s lost mass is about 5 million metric tons. When compared to the Sun’s total mass, the amount lost through nuclear fusion is almost insignificant. Therefore, we don't see the Sun decreasing in size.
The total mass is less after a fusion reaction. Some of the mass is converted into energy and given off due to the nuclear fusion reaction. For example. 2 atoms of hydrogen are fused to become 1 atom of helium. However, the helium atom will have less mass than the combined mass of the 2 original hydrogen atoms. The excess mass is lost via the energy given off from the nuclear fusion reaction.
Less than 1%.
If you talk about fission reaction (current nuclear power plants) then the mass is turned into energy, mostly in a form of heat, that is then turned to make energy in a massive closed system steam turbines plant.If you really mean Fusion reaction (humans not able to replicate such, but such is known to happen in stars), then there are no missing mass.
Some mass is "lost" during nuclear fusion and E = mc2 gives the amount of energy that this "lost" mass will be equal to.
it fusions
In nuclear fusion mass transforms into energy.
It stops at about 0.12 seconds.
Mass that is "lost" durning nuclear fusion is converted into binding energy to hold the newly formed atomic nucleus together. The lost mass, which is termed mass deficit, means the nucleus of the newly formed atom has less mass than the sum of the masses of the protons and neutrons that make up that nucleus. The stong reaction (strong nuclear force) participitates in the fursion reaction by mediating the conversion of mass into nuclear binding energy (or nuclear glue).It converts into the energy that is the desired end product of the reaction.

The mass that is lost during nuclear fusion is converted into energy according to Einstein's equation, E=mc^2. This released energy is what powers the sun and other stars.

Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
Energy
The mass is not lost but transformed in energy.
Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass.
