Toshiba has developed laser-based maintenance, inspection and repair technologies as countermeasures against stress corrosion cracking (SCC) in nuclear power reactors. Laser peening (LP) is a novel process for preventive maintenance, which improves residual stress from tensile to compressive on material surface by irradiation laser pulses in water. Laser-ultrasonic testing (LUT) is capable of detecting and sizing SCC having a depth of about 0.5 mm. Underwater laser welding can be fulfilled by making local ...

Code and standard Maintenance phase Regulatory technical standard
While the importance of maintenance is now being well recognized in terms of robustness of safety of NPP, code and standards for maintenance phase are not necessarily well organized so far in Japan. This paper presents some issues on promoting code and standards applicable to the maintenance phase from both standpoint of technical and management....

BWR Laser peening Preventive maintenance PWR Stress corrosion cracking (SCC)
Abstract: Laser peening (LP) is a process to introduce residual compressive stress on metal surface by irradiating laser pulses underwater without any surface preparations. Toshiba has developed and applied LP system to preventive maintenance against stress corrosion cracking (SCC) in nuclear power reactors since 1999. The system is composed of laser oscillators, a beam delivery system, a laser irradiation head, remote handling equipment and a monitor/control system. In the early applications, a rigidly l...
