ABSTRACT:
There is disclosed an apparatus including a calculating circuit for automatic determination of the boron concentration with the Li-ion concentration of the primary cooling water in a pressurized water atomic power plant. The conductivity of a sample of the cooling water is measured before and after the sample water is mixed with a mannitol solution; the Li-ion concentration is calculated from the measurement obtained and the correct boron concentration is calculated with correction based on the Li-ion concentration.
