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.
