Important application points include primary loop of nuclear power plants, boiler bleed-water in thermal power plants, denitrification of drinking water, and catalytic reduction of oxygen on noble metal surfaces in water treatment plants. The dissolved hydrogen concentrations within the water/ steam loop of a power plant gives quantitative and qualitative evidence of the rate of corrosion, corresponding to the buildup or destruction of the protective oxide layer inside pipes and boiler tubes.
