Application Note: Analysis of Copper, Nickel, Zinc and Common Cations in the Water-Steam Cycle of a Boiling Water Reactor
16 November 2012

Water chemistry of the water-steam cycle is crucial for maintaining plant reliability and for ensuring optimal plant operational conditions. Impurities such as corrosion products in ionic, colloidal or oxide forms are ubiquitous in feedwater, condensate and reactor coolant. This application note provides a method for the determination of sub-ppb levels of Cu, Ni, Zn and standard cations (e.g. Na+, NH4+, Mg2+ and Ca2+) in the water-steam cycle of a boiling water reactor.
