Eric--
Your bring up some interesting questions about the Rossi reactor. The
information I have included come from Rossi and Focardi's international patent
application noted below.
1. Is Rossi separating Ni isotopes for the Ni he uses in the reactor?
This would be expensive. The natural isotopic abundances are:
Ni-58, 68.08%;
Ni-59, 0%--its radioactive with 1/2 life of 80,000 years;
Ni 60, 26.22%;
Ni-61, 1.14%;
Ni-62, 3.63%;
Ni-63, 0%--its radioactive with 1/2 life of 92 years;
Ni-64, 0.93%.
I would pick Ni-60 because it is more than one transmutation (Ni-proton fusion)
away from a radioactive residue.
2. Is there radioactive ash (Ni-59 or Ni-63) left in the spent reactors?
Rossi and Focardi seem to contradict themselves with the statements below:
"...we believe that form of energy involved is nuclear, and more
specifically, due to fusion processes between protons and Nickel nuclei.
They are exothermic with an energy release in the range 3-7,5 MeV,
depending on the Nickel isotope involved."
"No radioactivity has been found also in the Nickel residual from the
process."
This information attributed to Focardi and Rossi comes from their instructive
statements, which suggest the nuclear Ni-proton fusion, in the following
paper:
A new energy source from nuclear fusion
S. Focardi(1) and A. Rossi(2)--(1)Physics Department Bologna University and
INFN Bologna Section, (2)Leonardo Corp. (USA) - Inventor of the Patent, March
22, 2010 (international patent publication N. WO 2009/125444 A1)
My final observation is that the Rossi-Focardi comment that there is no
radioactivity in the residue needs to be checked. Other Ni-hydrogen materials
that have been produced by other experimenters should be carefully checked for
both the potential radioactive Ni isotopes---Ni-59 and Ni-63. They should be
easy to detect given their well known decay modes and probable gamma emissions.
(I will look up this information and put it in a subsequent comment.) I know
that both Ni-59 and Ni-63 are problems when it comes to nuclear waste disposal
of activated metals.) A null radioactivity essay would be revealing as to the
process actually occurring in the Ni-hydrogen reactions.

Also I suspect that the nano Ni that is produced is pretty pure. That may
be why Rossi uses it and may be the reason other researchers do not have very
good luck at getting a good reaction.
I'm guessing that the purity of Rossi's nickel (in terms of 62Ni and 64Ni) is
related to avoiding beta-plus and beta-minus decay, and, with beta-plus decay,
the 511 keV positron-electron annihilation photons.
Some vorts may enjoy this video of a small cloud chamber [1]. It's
remarkable that such a small event can have macroscopic effects.
