激光喷丸技术在核电设备上的应用

Study on the application of laser-peening technique for nuclear power equipment

应力腐蚀或疲劳破坏严重威胁核电设备安全稳定运行,缓解或消除应力腐蚀或疲劳,是确保设备安全稳定运行的有效手段。采用激光喷丸技术,不存在影响设备正常运行的残留物,可以遥控至核岛内辐照区复杂狭小部位作业,而且效果显著,是一项前景广阔值得深入研究的应用技术。

Stress corrosion and fatigue failure are very dangerous factors concerned with the safe and stable operation of nuclear power plant.It is an effective means to ensure the safe and stable operation of nuclear power plant by releasing or erasing the stress corrosion or fatigue failure.By use of laser-peening technique,which reduce stress corrosion or fatigue failure effectually without residue,and can be remotely controlled in a narrow and complex radiated area of nuclear island.So it is a technique with bright future and worth study deeply.
