ActiveDesign specification for mechanical components in nuclear island of pressurized water reactor nuclear power plants—Part 4: Class 3 components
压水堆核电厂核岛机械设备设计规范 第4部分：3级设备
Application Summary AI generated
This standard specifies the design requirements for Class 3 mechanical components within the nuclear island of pressurized water reactor nuclear power plants. It is applied to components such as tanks, heat exchangers, and piping that have lower safety significance than Class 1 or 2 equipment, ensuring their structural integrity and performance under normal and faulted plant conditions. The standard guides engineers and procurement professionals in China to design, evaluate, and procure these components for new nuclear power plant projects or upgrades.
