A comparative study of hydrazine alternatives in simulated steam generator conditions—Oxygen reaction kinetics and interaction with carbon steel
Abstract
The efficiency of a range of hydrazine alternatives (carbohydrazide, diethyl-hydroxylamine, erythorbic acid and 2-butanone oxime) as oxygen scavengers and their interaction with carbon steel in simulated PWR steam generator inlet conditions are quantitatively compared. Kinetic parameters of oxygen reaction are estimated for the first time in such conditions using both an oxygen and a redox sensor. Electrochemical impedance measurements are performed to investigate the effect of studied alternatives on carbon steel corrosion. Using a quantitative interpretation of the impedance data by the Mixed-Conduction Model, the influence of hydrazine and its alternatives on charge transfer reactions at the oxide/solution interface and film growth/dissolution processes are discriminated. Conclusions are drawn on the comparative reaction rates of hydrazine alternatives with respect to oxygen consumption and steel passivation.
