Xinhuanet, Chengdu, January 17 news, unique radiation shielding technology, can rotate 360 degrees in the horizontal direction without blind spots, and it is stable and reliable even when working 100 meters underwater ... This set of nuclear developed by the Institute of Optoelectronics Technology of the Chinese Academy of Sciences Grade underwater high-resolution radiation-resistant camera system has been successfully applied to major domestic nuclear power bases recently. This indicates that China has broken foreign monopolies in this field and truly realized "Made in China".
Previously, underwater monitoring equipment at domestic nuclear power bases purchased foreign products. Feng Chang, deputy director of the Institute of Microelectronic Equipment of the Chinese Academy of Sciences' Institute of Optoelectronics, said that this system was independently developed by researchers of the Institute for two years, and was specially used in nuclear environments. Used in China's nuclear power bases.
The reporter learned that this set of 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. At the same time, due to the use of a high-performance image sensor with a resolution of 2 million pixels, it can output 1080P high-definition video. Under the driving of a precision motor, it can capture a jitter-free screen image at any speed.
"This system can improve the safety of nuclear fuel operation and ensure the long-term safe operation of fuel assemblies after they are put into the reactor." Feng Chang, for example, can monitor the operation of underwater fuel assemblies in an all-round way, such as during the core refueling of nuclear power plants. Ensure that the fuel is in place; perform a special underwater high-definition visual inspection and measurement of nuclear fuel components to understand the operating status of the fuel components. In addition, final safety inspections can also be performed on the spent fuel pools and core fuel assemblies of nuclear power plants to ensure that fuel assemblies are properly loaded.
Domestic nuclear power experts have unanimously affirmed the high-performance, high-reliability, and high-stable performance of the system during the overhaul of nuclear power bases in China.
