Abstract

Abstract

The corrosion behavior of Zr-Sn-Nb in the simulated PWR primary circuit zinc-injected aqueous chemical environment was investigated by autoclave corrosion test to analyze the surrosion and oxide film morphology of Zr-Sn-Nb alloy in zinc-free and zinc-added aqueous chemical environment. The results show that the surrosion curve of Zr-Sn-Nb alloy turns when it is corroded in zinc-free and zinc-added aqueous chemical environment for 150 days. Zinc addition has no significant effect on the surrosion, corrosion kinetics law, oxide film morphology, oxide film phase, oxide film thickness, hydride distribution and hydrogen absorption concentration of Zr-Sn-Nb alloy.
