AU175: Determination of Organic Acids and Inorganic Anions in Lithium-Containing Boric Acid-Treated Nuclear Power Plant Waters

Instrument Type: IC

In nuclear power plants with pressurized water reactors the primary coolant includes boric acid, which at high temperature and pressure can form crud. Lithium hydroxide is added to prevent this. Trace anionic impurities can serve as catalysts for corrosion. The experimental approach shown in this work combines the direct injection, electrolytically generated tetraborate eluent approach to analyze lithium-containing borated waters for fluoride, formate, chloride, and sulfate with the addition of a continuously regenerated cation trap column to remove lithium and other cations from the sample.
