It seems to me that there is a resonance process involved in these cases. When the temperature of the system matches the geometry of the thermal reactive medium, a reaction begins.
Like all LENR systems, the difficultly in predicting / reproducing the reaction is due to random factors in the nano-geometries of these systems. In a LENR+ system, the nano-geometry is well controlled and therefore the reaction is more predictable.
