光ファイバブラッググレーティング(FBG)センサを用いて、「常陽」1次冷却系配管歪み・振動の多点測定を行い、原子炉起動前の低放射線環境下におけるFBGセンサの適用性に関するデータを得た。

In JOYO, strain and vibration multi-point measurements of the primary cooling system piping have been carried out using a Fiber Bragg Graing (FBG) sensor. Through these measurements, applicability of a FBG sensor in a low-radiation environment was confirmed.
