岭澳核电站安装过程中 ,核承压设备的液体渗透工艺是按 RCC- M标准进行检测的。蒸汽发生器管板焊缝存在漏点 ,用常规的渗透工艺进行检测未能发现缺陷 ,改进和优化渗透工艺 ,可发现缺陷。本文就核电站液体渗透工艺及改进措施作简单介绍 Ling Ao Nuclear Power Station installation process, the nuclear pressure equipment, liquid infiltration process is based on RCC-M standards for testing. There was a leak in the weld of the tube plate of the steam generator, which was detected by the conventional infiltration process. No defects were found. The infiltration process was improved and optimized to find the defects. This article briefly introduces the liquid infiltration process and improvement measures of nuclear power station
