I think he ought to run it for a few hours and then put it in self-sustain mode, which I assume means no power to the internal resistance heater(s), and then let’s HOPE that it becomes unstable and goes critical!
I say, let it melt-down… With no input power, and coolant flowing, there is absolutely no alternative explanation to explain the extreme temperatures that would results, and when the post-mortem examination reveals a molten mass of Nickel. I can hear it now… the skeptics will argue that we can’t get any first-hand data since all the eye-witnesses were killed when it exploded! As for predictions, it’s now or never; make or break for Rossi… Given the track record, I’m not holdin’ my breath, but got my fingers crossed! J -mark
