Obstacle Avoidance Repulsive Vector Field Robot Manipulator
This study proposes an algorithm for automatic generating motion trajectories of robot manipulator. This algorithm consists of two procedures. First, motion trajectories of the tool head are generated by using the concept of repulsive vector fields and motion trajectories model which consists of a number of spr ings and mass. Then, a posture of robot manipulator is also automatically generated using the same concept. We are planning to apply this system as a remote handling device for nuclear power plants....

Laser peening Preventive maintenance Repair Stress corrosion cracking (SCC)
Multifunction laser welding head has been developed. The head is able to perform not only underwater laser welding as repair, but also laser peening as preventive maintenance and laser ultrasonic testing as inspection. By using the effect of color aberration with optics, laser beam was focused to the ideal spot size on each process. Laser p eening was performed on the material surface with the developed head, and stress improvement ability was confirmed....

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 Fuel damage Reactor bottom Vacuum cleaning Visual inspection
This paper describes development of the remotely operated device for vacuum cleaning and visual inspection in boiling water reactors to enhance the availability of operating nuclear power plants. Fuel damage can occur if loose debris inside t he reactor vessel flows through the fuel and it can become a serious issue affecting plant reliability and radiation levels, therefore, removing the small debris on the bottom head is significant activities in nuclear power plants. While it i s difficult to remove sma...
