Recently, the nuclear-grade underwater high-resolution radiation-resistant camera system has been successfully applied to major nuclear power bases in China. The application of this system has broken the foreign monopoly and truly realized the “Made in China” in the field.

It is reported that the system is researched and developed by the Institute of Optoelectronic Technology of the Chinese Academy of Sciences. Its technical indicators are in a leading position among similar products at home and abroad, breaking foreign monopoly in market applications and filling the domestic gap.

The high-resolution radiation-resistant camera system IOE-CPR-M has a unique radiation shielding technology that can work stably for 100 hours at a dose rate of 5000 Gy/h and has excellent image output. At the same time, the system is also equipped with special underwater dynamic sealing components, which can be stable and reliable under 100 meters underwater. This is the biggest advantage of the system. In addition, because of its high-performance image sensor, the resolution can reach 2 million pixels, and 1080P HD video can be output at the same time. Driven by a precision motor, the system is responsive and stable, ensuring that the captured image is jitter-free at any speed. Since the system can continuously rotate 360 ​​degrees in the horizontal direction, there is no monitoring blind zone in the underwater monitoring work of the nuclear power plant. The above technical characteristics make it possible to carry out similar products in the United States, and truly realize "Made in China" in this field.

High-resolution radiation-resistant camera systems have a wide range of applications in nuclear power plants, such as the ability to monitor the operation of underwater fuel assemblies in the nuclear power plant overhaul core refueling process to ensure proper fuel placement; special underwater HD for nuclear fuel assemblies Visual inspection and measurement to understand the health of the fuel assembly; final safety checks on the spent fuel pool and core fuel assemblies of the nuclear power plant to ensure proper loading of the fuel assemblies. It is worth mentioning that the system is equipped with video disturbance processing and image measurement technology independently developed by the Institute of Optoelectronics of the Chinese Academy of Sciences, which can perform video detection and image processing in a high temperature underwater environment to obtain high quality video images and related data. Overall, the system greatly enhances the safety of nuclear fuel operations and ensures long-term safe operation of fuel assemblies after they are stacked. It is understood that this system has played a significant role in the major overhaul of major nuclear power bases, and nuclear power experts have unanimously affirmed its performance of high performance, high reliability and high stability.

The National Medium- and Long-Term Development Plan for Nuclear Power (2011-2020) sets the goal. By 2020, China's nuclear power installed capacity will reach 58 million kilowatts and 30 million kilowatts under construction. It is foreseeable that with the good momentum of nuclear power continuing to flourish, the system will also play a greater role in the development of the national economy.
