Development of laser instrumentation devices for inner wall of high temperature piping system

Nishimura, Akihiko ; Furusawa, Akinori ; Takenaka, Yusuke*

We developed a cpmpact laser maintenance device in order to access a 23 mm diameter for heat exchanger tubes of nuclear power plants. A laser instrumentation device was desighned and assembled to measure the corrosion depth at the inlet of heat exchanger tubes. This device can be applied for heat exchanger tubes in CSP where erosion or cracking might be caused by repetitive thermal induced stress.
