Scope

Scope: This standard specifies the methods and related technical requirements for the stress corrosion crack propagation test of metal materials used in nuclear power plants in high-temperature and high-pressure water environments. This standard is applicable to evaluating the resistance of metal materials used in nuclear power plants to stress corrosion in high-temperature and high-pressure water environments. Main technical content: In the process of preparing this standard, reference was made to the national standards GB/T 10123-2001 "Corrosion of Metals and Alloys - Basic Terms and Definitions" and GB/T 24196-2009 "Corrosion of Metals and Alloys - Electrochemical Test Methods - Guidelines for Constant Potential and Dynamic Potential Polarization Measurement", as well as ASTM standards ASTM G129-00 "Standard Practice for Slow Strain Rate Testing to Evaluate the Susceptibility of Metallic Materials to Environmentally Assisted Cracking", ASTM E647-11 "Standard Test Method for Measurement of Fatigue Crack Growth Rates", and ASTM E399-06 "Standard Test Method for Linear-Elastic Plane-Strain Fracture Toughness KIC of Metallic Materials". At the same time, reference was also made to the technical documents prepared by the Institute of Metal Research, Chinese Academy of Sciences on the electrochemical test and stress corrosion crack propagation measurement methods of nuclear reactor materials in high-temperature and high-pressure water environments, and combined with the experience of the Institute of Metal Research, Chinese Academy of Sciences and related foreign research institutions in high-temperature and high-pressure water electrochemical testing and stress corrosion crack propagation measurement. The specific technical content is described as follows: (1) To achieve the loading of samples in a high-temperature and high-pressure water environment, a dynamic sealing connection between the loading system and the high-pressure reactor is required, and it should be ab
