摘要：

The corrosion behavior of chemically vapor deposited SiC was investigated in relation to its application as fuel cladding in a pressurized water reactor (PWR). Corrosion tests were conducted in deoxygenated, pressurized water at 360 degrees C with control of dissolved hydrogen. The dissolved hydrogen dramatically reduced the corrosion rate of SiC compared with that in water without the dissolved hydrogen. It was revealed that the dissolution of the surface oxide of SIC primarily contributed to the weight loss at the initial stage of corrosion. Further weight loss was minimal for 210 d because dissolved hydrogen effectively retarded the formation of SiO2. (C) 2015 Elsevier Ltd. All rights reserved.
