The ion concentration of the cooling system and the electric pile is not higher than 10 mu m s < -1 >, i0-TMS＝i0-stack＝10μm·s-1，i0-DI＝3μm·s-1。
According to instant detection data, the fact that the number 1 conductivity electrode data alarm exceeds the upper limit of the design value at a certain moment is found, calculation is carried out on the data 5s before the alarm value appears, and if the ion conductivity average value does not exceed the upper limit of the design value, the conductivity exceeding alarm is ignored.
