Basic Information
Scope
Scope: This standard specifies the test method for evaluating the sensitivity of metals exposed to high-temperature and high-pressure water and subjected to radiation in high-temperature and high-pressure water to stress corrosion cracking induced by radiation. This standard applies to the evaluation of the sensitivity of metals exposed to high-temperature and high-pressure water and subjected to radiation in high-temperature and high-pressure water in nuclear power plants. This standard applies to the simulation of radiation-induced stress corrosion cracking sensitivity in high-temperature and high-pressure water using rectangular cross-sectional specimens with a certain gauge length and controlled axial displacement in a 360°C and 20MPa or lower water medium. Product components and other special-shaped specimens can refer to this standard for implementation. Main technical content: During the preparation of this part, reference was made to the national standards GB/T 10126 "Stress Corrosion Test Method for Iron-Chromium-Nickel Alloys in High-Temperature Water", GB/T 15970.1 "Corrosion and Stress Corrosion Test of Metals and Alloys - Part 1: General Principles of Test Methods", GB/T 15970.7 "Corrosion and Stress Corrosion Test of Metals and Alloys - Part 7: Slow Strain Rate Test", GB/T 16825.1 "Inspection of Static Single-Axis Testing Machines - Part 1: Inspection and Calibration of the Loading System for Tensile and/or Compression Testing Machines", and ASTM Standard E521-96 "Standard Practice for Neutron Radiation Damage Simulation by Charged-Particle Irradiation". Relevant provisions on the simulation of neutron radiation-induced stress corrosion testing technology were also referenced. At the same time, the technical documents on the simulation of high-temperature and high-pressure water-induced stress corrosion cracking prepared by the Institute of Metal Research, Chinese Academy of Sciences, and the implementation experience of high-temperature and high-press
