| Abstract: | Reasons of failure in cooling pipe of the reactor have been studied by the chemical composition analysis, optical microscopy examination and electron probe microanalysis. The results show that the early failure of the cooling pipe was caused by the stress corrosion cracking in the components. According to the working condition, the improvement measures had been adopted in material selection and construction design, the service life of the cooling pipe has been prolonged. |
