Nuclear fission involves the most powerful (at this scale) force of nature_: the strong interaction. The view has very little physical sens. In real life, nucleons do not look like small balls, moving neutrons do not look like fire, electrons do not look like little spining balls (even if they did, they would be much much far away from the nucleus). In fact, they do not "look like" at al. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The first (small) difficulty was to find the right random distribution to get nucleons and electrons uniformly spred on a sphere. Then, I add some scattering media and a light for the exploding atoms, to get the light rays. The moving neutrons and the electrons are emmiting media. For the electrons, I wrote a density "torical" function that is the analogous of the spherical and cylindrical ones. At last, I randomly placed the background atoms.
