Fusion cannot create a supernova, only gravitational collapse reflected shockwaves can create a supernova. Fusion does cause novas though. If a white dwarf or neutron star is in a binary system with an ordinary star, it can collect gas on its surface from the wind and flares of that star, when enough hydrogen collects to ignite fusion the star lights up as a nova. This can repeat periodically as more gas collects. Supernovas cannot repeat.

Stars - by nuclear fusion, by supernova explosions, and by colliding neutron stars.
No, only large stars go supernova when nuclear fusion breaks down. While white dwarfs can go supernova in some instances, brown dwarfs are failed stars which are not powered by nuclear fusion.
The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.
The onset of iron fusion causes a star to become a supernova. This process occurs when the star's core collapses due to the inability to support the fusion of iron, leading to a catastrophic explosion.
stars through processes such as supernova explosions. These reactions involve the fusion of lighter elements to create heavier ones, including elements like gold, uranium, and plutonium.
Nuclear fusion in stellar cores, such as in stars like our sun, can lead to the formation of larger elements through the fusion of lighter elements. Supernova explosions can also create conditions necessary for the synthesis of heavy elements.
The heaviest element that can be produced prior to supernova is Iron (Fe).
supernova
A super giant star can explode in a spectacular event called a supernova. During a supernova, the star releases an immense amount of energy and blasts its outer layers into space. This explosion can also create heavy elements through nuclear fusion.
In a supernova event, elements such as hydrogen, helium, carbon, oxygen, and heavier elements like iron are produced through nuclear fusion and nucleosynthesis processes.
It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event. These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star. In this catastrophic event, the iron and silicon (and any other lighter elements) in the star are super compressed. The already hot conditions are made even hotter, and the available energy is sufficient to drive the fusion reactions that create the trans-iron elements.All the fusion reactions up through those that create iron are exothermic, and that means they release energy. The fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements.See periodic table (iron is number 26).See related link.
