4.4压水堆核电厂机械设备材料标准需求到目前为止,我国在“十五”期间的核电工程项目,呼声较高的是1000MW级的压水堆核电厂。因此,我们下面拟根据RCC-M的形式来列出压水堆核电厂机械设备材料标准的清单。这里所说的机械设备不包括核燃料组件、小型设备、低压和常压贮罐及焊接用 4.4 Pressurized Water Reactor Nuclear Power Plant Mechanical Equipment Materials Standard Requirements So far, China’s nuclear power project during the “Tenth Five-Year Plan” period, the higher the voice is the 1000MW PWR nuclear power plant. Therefore, we will list below a list of material standards for mechanical equipment for PWR nuclear power plants based on the form of RCC-M. The mechanical equipment mentioned here does not include nuclear fuel assemblies, small equipment, low pressure and atmospheric storage tanks and welding
