Contamination Control Filtration Lubricant Proactive Maintenance
Lubricant management is very important to maintain the integrity of rotating equipment. Lubricant is periodically replaced and monitored on its aging degr adation between replacement times. On the other hand, only the confirmation of specification document has been performed as acceptance inspection in case of new lubricant. However, a comparatively large amount of impurity substances has been found in new lubricant by sample analysis. Therefore, the introduc tion of contamination control of new lubricant ...

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 ...

Cr stainless steel Fatigue Laser peening Residual stress Turbine blade
Some damages were found at the forks of low pressure turbine blades caused by random vibration and steam-flashback vibration. In this study, for the aim of fatigue property improvement, laser peening technology for 12Cr stainless steel was developed and material properties were examined. Laser peening is a process to induce compressive residual stress to the material surface. Fatigue specimens which simulate the stress concentration zone of forks were fabricated and laser peening was applied to the su...

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...
