The above referenced analysis describes the amount of increase or decrease in the masses of the various components of the fuel change. Certain components of the fuel increased and others components decreased. This analysis also speculates about how these changes in masses of the various fuel and ash components might be brought about by movement of material from the hot parts of the reactor to colder regions, and also how lithium migrates to the surface of the nickel particles for transmutation and then when processed are somehow transported to other parts of the reactors volume.
All this movement must be happening through some means of chemical transport. But the mix of fuel and ash forms a solid mixture that seems incomparable with the movement of elements in a transport medium.
I see one possibility to explain how the moment of these elements and chemical compounds might be possible. These fuel and ash components could move around in the hydrogen gas atmosphere as nanoparticles. What is hard to explain is how the mass of nickel component of the fuel can increase in the ash to double it weight as originally configured in the fuel load. The nickel particles had a very intricate surface tubercle structure that makes it impossible to structurally modify the particle without affecting the tubercles.
But the isotopic composition of the nickel particles originally in the fuel changed throughout their entire volume as if subatomic particles traveled through the volume of these particles. A hydrogen negative ion as postulated by Piantelli cannot penetrate into the center of the nickel particle to produce isotopic transmutation. The active agent in this isotopic transformation must be a subatomic particle.
The other type of nickel particle found was the smooth surface kind that must have been formed by gradual accumulation of transmuted Ni62. What and how this type of nickel particle is produced is an open question. The same type of gradual accumulation must have had to produce the iron micro particles.
