概要
Fiber Bragg Grating（FBG）is a kind of an optical device developed rapidly in these years and it has several excellent characteristics as a sensor for tempera- ture and/or strain. To investigate the applicability of FBG even as a vibration sensor for nuclear plant monitoring, novel measurement systems were devel- oped and tested. The results revealed that the FBGs had sensitivity to vibration and temperature even in radiation environments. Vibration and/or temperature of components around cooling systems at the YAYOI and JOYO reactor could be detected successfully with FBG based sensors.
