Thermal Energy Storage (TES) is important to stabilize increasing large amount of fluctuating renewable energy. For safety operation of TES, remote sensing by Fiber Bragg Grating (FBG) sensors is expected. FGB sensors were fabricated using precisely focused picosecond laser pulses. For the best use of heat resistant characteristic, we demonstrated to embed the FBG sensors in metal mold using colloidal silver adhesive. The FBG sensors were tested using a sodium circulation loop in JAEA Tsuruga site. Sodium was circulated with temperature of 500 degree. During emergency cooling, sudden shrinking of the loop was recorded. The application of FBG sensors to advanced remote monitoring for next generation TES plant is proposed.
