Abstract

Flow-through cells for monitoring high-temperature water chemistry have been designed and installed in the shutdown cooling system at Olkiluoto unit 1. The aim is to find correlations between water chemistry data and oxide film proper-ties in the BWR coolant, susceptibility to stress corrosion cracking and other forms of corrosion and the rate of activity incorporation. The employed monitoring unit has been in operation for one year. It provides relevant information that can be used both for assessing long-term trends and for sensitive detection of rapid changes in the coolant environment. High-temperature conductivity of the coolant has proven to be a sensitive indicator of changes in anionic impurity content and temperature variation of the coolant.
