Successful operation of a nuclear power plant (NPP) demands careful control and monitoring of water chemistry in primary coolant dosed with boron and lithium, steam generator tubes dosed with ammonia, closed cooling water systems dosed with nitrite and other structural parts that are subject to corrosion and crud deposition. This can affect plant operation and radiation exposure during refueling downtime.
Ion chromatography is the safe and reliable method of choice to determine both µg/L (ppb) and mg/L (ppm) levels of anions and cations including transition metals in power plant waters. Cation-exchange chromatography with non-suppressed conductivity detection is a simple and direct technique for quantifying low-µg/L concentrations of selected transition metals.
Lithium-borated water, and ammoniated condensate, is measured for low-level µg/L concentrations of fluoride, chloride, and sulfate with the addition of a continuously regenerated cation trap column (CR-CTC) to remove interference from mg/L concentrations of either lithium or ammonia in the samples. Other closed cooling water systems are dosed with high nitrite concentrations (up to 1000 mg/L) to prevent corrosion, but low-level µg/L chloride measurement is required for early signs of seawater ingress. This is possible with a Thermo Scientific™ Dionex™ AS14A Eluent Concentrate; (Sodium Carbonate/Bicarbonate Concentrate).
