Feasibility on the Use of Phased Array Inspection as a Replacement of Radiographic Inspection for Butt Welding of Steel Containment Vessel of Nuclear Power Equipment

  • 摘要: 核电设备钢制安全壳作为核反应堆放射性防护的三道屏障之一,对核电的安全性起到至关重要的作用。钢制安全壳对接焊缝的无损检测按照ASME要求需进行100%的射线检测,但是射线检测存在一定的漏检率,尤其是对面积型缺陷(裂纹、未熔合)的检出率较低,并且随着板厚的增加,射线检测的漏检率也不断增加。对相控阵技术进行分析,通过在一定数量的自然缺陷试块上采用相控阵和射线检测进行验证,对比分析得出结论:相控阵检测技术在钢制安全壳对接焊缝检测中具有可行性,可作为一种可靠、高效、经济的技术手段应用于焊缝的质量检测。
    Abstract: Nuclear power equipment-steel containment vessel as a nuclear reactor radiation protection of one of the three barriers, plays a crucial role on the safety of nuclear power. Steel containment vessel of the butt weld generally requires for 100% the radiographic testing, but radiographic testing has a certain undetected rate, especially the detection rate for planar type defects (cracks, incomplete fusion) is low, and with the increase of thickness, the undetected rate of X-ray testing also increases. Through simulating a certain number of defects on the block to verify the detection between PAUT and RT, we make a conclusion that the PAUT for testing the butt weld of steel containment vessel is feasible, which may provide a reliable, efficient and economic testing method for weld quality.
