Description

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 temperature and/or strain. To investigate the applicability of FBG even as a vibration sensor for nuclear plant monitoring, novel measurement systems were developed 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. (author)
