I think there are multiple nuclear processes going on , wherein the one that generates neutrons is what triggers the secondary nuclear process, p-p fusion which is what occurs in our Sun and is the most common naturally occurring nuclear fusion process in Nature... by far.
We discussed the idea that incorporating a secondary neutron source and suitable activation methodology to the overcome the barrier to either get the ball rolling or even to mediate the cold fusion reaction could overcome the barriers and result in in a workable hybrid type of device.
Unfortunately, at the time, the last thing the guys that controlled suitable neutron sources and related hardware wanted to do was encourage cold fusion heretics in their research and, more importantly, in their search for dwindling sources of research dollars.
