反应堆压力容器接管与筒体焊缝超声检测技术研究

Research of Ultrasonic Inspection Technique on RPV Nozzle to Shell Weld

根据华龙一号反应堆压力容器接管与筒体焊缝的特点、检测难点和规范要求,开发专用的超声检测技术,并对其可靠性及定量精度进行仿真分析和缺陷模拟试块验证。验证结果表明可有效检出设计缺陷,且缺陷定量结果满足规范要求。

In this paper,a set of ultrasonic testing technology is developed according to the characteristics and specification requirements of the weld.The process is simulated and verified on a simulated block with defects.The verification results show that the developed ultrasonic testing technology can effectively detect the defects in the simulated test block and the defect quantitative analysis results meet the specification requirements.
