The long running time of the Rossi process is a clue.
The very long running times of the Rossi process being reported to run up to two years, lends weight to the opinion that elements in the catalyst are not consumed in the Rossi reaction. The nanopowder that makes up the various components of the catalyst remains functional for a very long time. If nickel was consumed, the nano-nickel particles would be systematically destroyed over time. A hydrogen only nuclear process in which only hydrogen transmutes to other elements is the likely explanation.
