Gel Immersion Technique Phased Array UT SAFT Ultrasonic
Inspection technique for complex surface profiles has been required in order to ensure the reliable operation and high operating rate of nuclear power plants, because many parts due to inspection have complex geometry. We have developed Pha sed Array (PA) ultrasonic testing with immersion technique which suitable to complex geometry. In this paper, we developed precise inspection technique for curvature surface profile such as a nozzle of pressure vessel. For curved surface pro file, Synthesis Aperture Foc...

JANTI Guideline mitigation SCC ULBW
JANTI Guideline on underwater laser beam clad welding for preventive maintenance against SCC was published. This paper introduces the summary of that guideline. Underwater laser beam welding has good advantages for the repair and mitigation work for operating nuclear plants' reactor internals. Since it does not need to drain the water from RPV, preparation before the work can be very concise, and dose rate that workers suffer can be controlled in very low level. And heat input during the welding procedure ...

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...

BWR core shroud Inspection and Evaluation Guideline SCC
This paper introduces the applied experience of Inspection and Evaluation Guideline for Japanese BWR plants' core shroud. This report includes the compari son of evaluation performed by using Guideline's method and actual inspection results for several plants. Evaluation was performed at the time when SCC wa s found. After one cycle operation, actual inspections were done to confirm the amount of existing crack growth. It was confirmed that actual crack growth is less than predicted value by the evaluation...
