Don't forget that only a tiny sample of the ash was measured. It's entirely possible that the sample just happened to be one in which the process was complete. If the reaction wasn't uniform throughout the reactor then there may have been other regions where the reaction wasn't complete, and was still producing energy. >On Sat, Oct 25, 2014 at 3:18 PM, Alan Fletcher <[email protected]> wrote: > >So maybe the hotcat wasn't running OUT of fuel at 32 days : it had >> completed the Ni isotope conversion (to a greater degree than Rossi >> expected), and was then running at peak efficiency? >> >> This could explain the improvement in efficiency over the first half, when >> the input power could be reduced. >> > >This makes sense in part, as there is probably nothing particularly special >about nickel-7Li neutron stripping reactions.
