The heater is in five segments. My guess is there is a need to maintain a gradient in order to start the reactor and that is the work of the PLCs. They lost two of the five segments but were able to get the reactor to start regardless. Curiously, Levi says that they could not get it to self - sustain with only three working segments like they did in the December test. Kewl, eh? It broke but they still make it work. The old Rolls Royces had both a hand crank and a electric starter. :-) T
