... and microchemistry of materials have been analyzed and compared before and after exposure. The results show that polishing deteriorates the corrosion resistance, while grinding enhances the anti-oxidation and anti-carburization capability of materials. Thick and unprotective Fe-rich oxides are formed on the polished...

... Abstract CZ Alloys, including CZ1 and CZ2, are new advanced zirconium alloys developed by China General Nuclear Power Group. This paper presents the oxidation behaviour of CZ Alloys and Zircaloy-4 in flowing steam. A SETSYS Evolution TGA (ThermoGravimetric Analyzer) is used for the high...

... and disassembly. In this paper, the performance of lubricant materials such as wear resistance and high temperature oxidation resistance under irradiation environment were studied. The results show that the lubricant grease does not change significantly and there is no grease stratification after irradiation...

... experiments and literatures show which is closely related to its excellent alloy materials. that the formation of chromium rich protective oxide layer However, due to the high temperature of helium in the on the surface of superalloy is an important factor to prevent primary circuit, a small amount...

...Abstract Abstract In order to contribute the improvement of estimation accuracy for severe accident code such as SAMPSON, we have developed the chemical reaction model such as eutectic reaction and oxidation in micro scale, e.g., B 4 C-SUS in the control rod blade and UO 2 -Zry in fuel rods...

... should be qualified carefully on SCC effect. This paper introduces research status of SCW chemistry by Nuclear Power Institute of China (NPIC). The SCC behaviors in oxidation and reduction SCW are under study and the testing data will be collected to screen out water chemistry operating strategy...
