Long-term temperature monitoring in a low flux nuclear reactor using fiber Bragg grating sensors
نویسندگان
چکیده
Multiplexed FBG temperature sensors are used to measure a temperature profile inside an irradiation channel of a low flux nuclear reactor. After 40 months, we show that the sensors still operate satisfactorily. The measured drift is lower than 3 ◦C.

Long-term radiation effects on fibre Bragg grating temperature sensors in a low flux nuclear reactor
Fibre Bragg grating (FBG) temperature sensors have already shown short-term radiation tolerance in nuclear environments. However, the effect of long-term irradiation needed to be investigated. We therefore characterized multiplexed FBG temperature sensors inserted early 2000 in an irradiation channel of a low flux nuclear reactor. After 50 months, we show that the sensors still operate satisfac...
متن کاملTemperature monitoring of nuclear reactor cores with multiplexed fiber Bragg grating sensors
Alain Delchambre Université libre de Bruxelles CP 165/41, 50 av. F.D. Roosevelt B-1050 Brussel, Belgium Abstract. In-core temperature measurement is a critical issue for the safe operation of nuclear reactors. Classical thermocouples require shielded connections and are known to drift under high neutron fluence. As an alternative, we propose to take advantage of the multiplexing capabilities of...
متن کاملField Deployable Fiber Bragg Grating Strain Patch for Long-Term Stable Health Monitoring Applications
A fiber Bragg grating (FBG) strain patch specially adapted for long-term and high-strain applications has been developed and characterized. The design concept for the patch is based on a glass-fiber reinforced plastic (gfrp) carrier material. The developed concept for the FBG integration into the carrier material was derived from reliable integration procedure of FBG sensors into composite stru...
متن کاملFiber Optic Bragg-Grating Sensors
In-fibre Bragg gratings are sensor elements which are photo-written into optical fibre using intense ultra-violet laser beams and have the potential for the measurement of strain/deformation and temperature with applications reported including monitoring of highways, bridges, aerospace components and in chemical and biological sensors. The development of a fiber Bragg grating (FBG) measuring sy...
متن کاملFeasibility of Fiber Bragg Grating and Long-Period Fiber Grating Sensors under Different Environmental Conditions
This paper presents the feasibility of utilizing fiber Bragg grating (FBG) and long-period fiber grating (LPFG) sensors for nondestructive evaluation (NDE) of infrastructures using Portland cement concretes and asphalt mixtures for temperature, strain, and liquid-level monitoring. The use of hybrid FBG and LPFG sensors is aimed at utilizing the advantages of two kinds of fiber grating to implem...
