摘要
Hydrogen evolution and corrosion rates for an Alloy 800H flow-through reactor operating under supercritical water conditions were determined. Experiments were performed in the temperature range of 650 to 750 degrees C both with deoxygenated feed water, with an O-2 concentration of less than 10 mu g L-1 (ppb), and with a high oxygen concentration of around 20 mg L-1 (ppm). Effective rate constants for hydrogen evolution during the corrosion of an Alloy 800H were calculated to be 2.52 x 10(-11), 2.88 x 10(-11) and 4.30 x 10(-11) molcm (-2) s(-1), for the reactor temperatures of 650, 700 and 750 degrees C, respectively.
