A modification of the absorption-spectral photometric method and a system based on it are proposed for measuring boric acid concentrations from 0.01 mg/liter to 10 g/liter or more to within 0.01 mg/liter directly in cooling loop of a water moderated and cooled power reactor. Compared with other systems, the method permits increasing the sensitivity and accuracy of boric acid concentration measurements 1000-fold and monitoring the concentration remotely at a radiation-safe distance.
