FBG Sensing Technology for the Temperature Monitoring of Nuclear Reactor in Nuclear Power Field

Temperature monitoring is a crucial aspect of nuclear power plant safety. The accurate and reliable measurement of temperature is required to ensure the safe and efficient operation of a nuclear reactor. Fiber grating sensing technology has emerged as a promising solution for temperature monitoring in nuclear reactors.  In this article, we will discuss the problems that fiber grating sensing technology can solve, and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the temperature monitoring of nuclear reactors in the nuclear power field.

Fiber Bragg Grating Sensing Principle:

Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.
