概要
Strain sensors, which can be used for integrity monitoring of plant components and piping during the operation period continuously, are effective from the point of view of proac tive maintenance. FBG (Fiber Bragg Grating) sensor is one of the expective sensors and is used in various plants and civil engineering and construction fields except for high te mperature service. In order to apply to the component and piping of fast reactor, heat resistance is an indispensable feature of the sensor. In this study, we tried to improve he at resistance of FBG by using femtosecond laser in the process. The heat resistance at the FBGs was examined experimentally and the results compared with those of ordinary FBGs.
