いた。Conventionally, the ion load of the ion exchange resin in the condensate desalination equipment has been evaluated using the so-called μS/cm −To, which is the cumulative product of the difference in conductivity of the inlet water and outlet water of the condensate desalination equipment and the amount of treated water.
The timing of chemical regeneration of the condensate desalination equipment was determined by this μS/CTl1·on control.

At the inlet of the desalination equipment, the condensate is converted to ultrapure water (0,055 μs/cm −0
, 07 μs/cm) L, so the ion load on the condensate desalination device is extremely low.

あった。In this way, when the condensate purification system of a nuclear power plant is duplicated and the inlet water of the condensate desalination equipment is ultra-pure,
The difference in the conductivity of the water at the inlet and outlet of the condensate desalination equipment is about the same as the instrument error of the conductivity needle, which is less than the difference, so the conventional chemical control method for the condensate desalination equipment is μs/cm- There is a problem in that Ton control cannot be accurately controlled and therefore it is not possible to know the exact ion load level of the condensate desalination equipment.
