A HIGHLY DETECTIVE APPARATUS AND METHOD FOR LEAKED CARBONACEOUS SPECIES FORM THE ION EXCHANGE TOWER IN NUCLEAR POWER PLANTS

摘要

The present invention relates to a detection apparatus and a detection method carbonate species , more particularly the heavy water reactor type nuclear power plant is related to the detection device and a detection method for detecting leakage of acid species with high sensitivity by the ion exchange resin column . ; invention , ; 1) obtaining a test sample by taking a portion of the ion exchange resin treatment can be passed through the tower ; ; 2) said sample was passed through a number of steps to the mixing column to convert bicarbonate ions in a sample can as sodium chloride ; ; 3) the conversion of hydrochloric acid was passed through a number of samples containing the sodium chloride in the cation column stage ; ; 4) using an electrical conductivity measuring cell, the concentration of hydrochloric acid ; the acid species provides a sensitive detection method comprising
