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