Abstract
The effects of Zn injection and Ni/Fe ratio on the corrosion and crud deposition behaviors of FeCrAl fuel cladding in high-temperature pressurized water with high dissolved oxygen were investigated. The phase compositions of external oxide particles and crud particles are both affected by Ni/Fe ratio. The internal oxide film with a porous structure is mainly composed of Fe2O3 and ferrite-rich spinel, and only a thin Cr2O3 layer was observed in the oxide film/matrix interface. Zn injection only slightly reduces the porousness and thickness of the internal oxide film even if obvious Zn enrichment in the internal oxide film was detected.
