FBG Sensing Technology for the Temperature Monitoring of Nuclear Fuel Rod
Nuclear power is one of the most efficient and clean sources of energy in the world. However, ensuring the safety and reliability of nuclear power plants is of utmost importance. One critical aspect of nuclear power plant safety is monitoring the temperature of nuclear fuel rods. This task is challenging and requires advanced sensing technologies to ensure accurate measurements. Fiber grating sensing technology offers a potential solution to this challenge and is gaining attention in the nuclear power industry. 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 fuel rod in the field of nuclear power.
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.

Demand Analysis for Temperature Monitoring of Nuclear Fuel Rods:
Nuclear fuel rods are a critical component of a nuclear reactor, and their temperature must be closely monitored to ensure safe and efficient operation. Accurate temperature measurements are essential to prevent fuel failure, which can lead to radiation leaks and other hazardous situations. Therefore, temperature monitoring of nuclear fuel rods is a crucial aspect of nuclear power plant safety.
Why Temperature Monitoring of Nuclear Fuel Rods is Required :
Nuclear fuel rods contain nuclear fuel, which generates heat through nuclear reactions. The heat produced must be controlled to prevent the fuel from overheating and melting, which can cause a nuclear meltdown. Therefore, it is essential to monitor the temperature of nuclear fuel rods to ensure that they remain within a safe operating range.
Difficulties in Temperature Monitoring of Nuclear Fuel Rods:
Temperature monitoring of nuclear fuel rods is challenging due to the extreme conditions within a nuclear reactor. The high levels of radiation, high temperatures, and corrosive environment can degrade conventional temperature sensors, leading to inaccurate measurements. Furthermore, access to the fuel rods is limited, making it challenging to install and maintain sensors. Therefore, advanced sensing technologies are required to overcome these challenges and ensure accurate temperature measurements.
