反应堆压力容器超声波相控阵检测工艺研究

Research on PA Ultrasonic Inspection Technology in RPV

通过对反应堆压力容器(RPV)模拟体建模,研发相控阵(PA)超声波检测技术,以代替常规超声波检测技术,并对2种检测技术的检测能力和定量能力进行对比和评估。验证试验表明,PA超声波检测技术的检测和定量能力满足标准要求,且可大幅度缩减检测时间,具有可观的经济价值。

By building the RPV model, the phase array(PA) ultrasonic detection technology was developed to replace the conventional ultrasonic detection technology, and then the detection and quantitative capability of the two detection technologies were compared and evaluated. The verification tests show that the detection and quantification capability of PA ultrasonic detection technology meets the standard requirement. At the same time, it can greatly shorten the inspection time and have considerable economic benefits.
