| Summary | This standard specifies the general test items, test conditions, test methods and acceptance criteria used in the identification of safety grade pneumatic control valves for nuclear power plants. For specific function of the valve, according to the technical specifications required to carry out additional tests. The accessories used in the control valve, such as solenoid valves, locators, etc., need to be carried out according to the corresponding standards and certified, not within the scope specified in this standard. This standard applies to installation in the PWR nuclear power plant, has undergone normal conditions, abnormal conditions and nuclear power plant design benchmark events, requiring the performance of the control valve. This standard is also available for reference to other types of nuclear power plant control valves. |
