美国电力科学研究协会 (EPRI)开发出一种相控列阵超声波 (phased- array ultrasonic)技术 ,用以更快、更准确地对核电用汽轮机组件进行无损检测 (NDE)。美国的 Arizona公共供电公司和 Alliant能源公司在停电检修期间都用该技术对汽轮机叶轮叶片焊接区进行了成功检测。以前核电
The American Society of Electric Power Research (EPRI) has developed a phased-array ultrasonic technique for non-destructive testing (NDE) of nuclear turbine components faster and more accurately. Both Arizona Public Supply Company and Alliant Energy Company of the United States used the technology to successfully test the turbine blade pad area during blackouts. Previous nuclear power
