초록

Flow Accelerated Corrosion (FAC) causes unexpected accidents in a secondary side of a nuclear powerplant. The secondary side pipes are mainly carbon steel tubes that have a protective magnetite (Fe3O4)layer on the inner surface. The stability of the protective magnetite layer depends on the parameters relatedto the FAC phenomena such as pH, temperature, flow rate, surface roughness etc. The dissolution of magnetiteis basically the electrochemical reaction, but the most of the experiments of magnetite dissolution werecarried out thermodynamically to determine the solubility of magnetite. The knowledge of the electrochemicalproperties of magnetite is required to understand the dissolution process of magnetite. This paper reviewsthe manufacture of the magnetite (Fe3O4) electrode, and summaries the electrochemical properties of themagnetite.
