Could the drop in apparent resistance of the reactor heater element in the Lugano report be in part due to the core ceramic conducting at high temperature and partial shorting between the 3 phases?
There have been burn outs, core breaches, melted heater wire, hot spots and arcing thermocouples over the months.
Alan Goldwater deduced there was a drop in resistance in the ultra pure Al203 Coorstek cores we were using.

Additionally, SiO2 based ceramics resulted in plain shorts causing loss of thermocouples.
More recently, Adriano Bassignana made us aware of the Nernst Lamp
Of course, most replicators reactors to date have been single phase. So the differential between two adjacent coil loops where ceramic conductivity has increased would be lower than that between a parallel, helically wound, 3 phase coil.
