| Summary | This standard specifies the monitoring methods, monitoring procedures and requirements for monitoring systems and monitoring documents for the internal components (including fuel assemblies) of PWR nuclear power plants. This standard is applicable to the monitoring of the vibration signal of the neutron fluctuation signal and the pressure vessel of the reactor and the vibration behavior of the internal components of the pressurized water reactor. At the same time, the vibration of the primary circuit and the pressure fluctuation of the coolant can be additionally measured to detect the deterioration of the structural support of the primary circuit. Other stack types can also be referred to for execution. |
