We developed the fiber Bragg grating (FBG) sensor system with high temperature tolerance for a deterioration evaluation of passing year and seismic safety in nuclear power plant. We examined the heating tolerance and the load transformation of the reinforced FBG sensor system. As a result, the strengthening FBG sensor was an excellent adhesion performance in the environment of 400 $^{circ}$ C or less. Additionally, the load transformation examination was executed under the high temperature environment, and it was confirmed that the measurement of the amount of the transformation was possible with strengthening FBG sensor.
