As mentioned in a previous thread, it may be possible for the stainless cell to get hotter than the Ni, particularly if the inner coating is thin. If the heat is conveyed from the NAE via photons, the photons could be absorbed in the 3mm thick stainless cell rather than in the thin Ni coating. If the reaction flashed, it could cause a meltdown that wouldn't or maybe couldn't happen if the transport was phonons.
Think about a thermonuclear device where a fission fuse creates X-rays which are focussed on the fusion pit to compress it. The photonic compression occurs before the fission reaction blows the apparatus apart. A rapid Ni-H LENR could cause a tremendous photon flash that could melt the SS cell. However, there is only anecdotal evidence of a meltdown was caused by a Ni-H LENR. If the reactor over-heats slowly from photons (or anything else), then it is likely that the reaction will self-extinguish as the NAE is destroyed at a temperature long before a melting of Ni or the SS would happen. In another speculation, Rossi said that he had tried other catalysts but had not found one that was as high performance as his original catalyst. However, one of those other catalysts may have been higher temperature but lower COP. Rossi may have switched catalysts to get to the higher temperature operation. I am experimenting with Fe nanopowder that I believe may have been Rossi's original catalyst. His alternative may be zirconia nanopowder. In either case, I believe the nanopowder is not just mixed in - it is thermo-chemically processed after being mixed on a nanoscale with the micro-Ni to create the NAE. Zirconia is a more durable oxide that may remain in a useful nano form on Ni to a higher temperature. Think of the nano-particles, partly oxidized, as nano-wedges to create cracks.
