The present invention relates to a method and a system for monitoring traces of boron ion of mixed solution for monitoring light water nuclear power plant steam generator tube leakage online. The present invention relates to an online leakage monitoring technique of a light water nuclear power plant steam generator tube for monitoring the leakage of the steam generator tube by analyzing the density of the traces of boron among solution on which various ions are mixed. The present invention solves a problem of overlapping a boron ion and anions in combination with an enriched anion column and a separated anion column and improves reactivity with the boron ion by using Sorbitol instead of existing Manitol for increasing the conductivity of the boron, wherein it is unnecessary for a preprocessing step and a separate deaerating step which takes much time and a large number of microfilters by removing all cations within a secondary system to an anion suppressor. The present invention has an effect of early detection of microdefect of the steam generator tube and accurate recognition of the quantity of leakage since the density of minute amounts of boron ion is monitored accurately in an environment that the density is lower than 5 ppb or the quantity of leakage is 5 gallon per day (GPD). |
