China has its own design and independent manufacturing capacity for spent fuel storage grids, breaking the monopoly of foreign technologies.
On November 10th, the reporter learned from China Guangdong Nuclear Power Corporation that the China National Machinery Industry Federation organized the identification of the spent fuel storage grid independently developed by China General Nuclear Power Group on the same day and considered that the technology based on the “integrated skeleton + modular storage sleeve†technology was developed. The various performance indicators of the fuel storage grid have reached the international advanced level.
The spent fuel storage rack is the core equipment in the nuclear fuel cycle, and is widely used in the storage of spent fuel in piles, in intermediate storage and storage in reprocessing plants. With the rapid development of China's nuclear power industry, the demand for spent fuel storage grids is huge. However, due to the restrictions on the key functional materials in the spent fuel storage grid, such as the neutron absorber material, localization has not been achieved and foreign imports have been relied on. Not only is the product supply price expensive, but also the technology and supply cycle Constrained.
In view of this, China Guangdong Nuclear Power Co., Ltd. and Jiangsu Nuclear Industry Green Water Treatment Co., Ltd. have successfully developed a new type of "integral skeleton + modular storage sleeve" spent fuel storage grid, while effectively reducing costs, but also effectively avoid the current nuclear power project in China The problem of grid deformation and other problems that occur with high-density spent fuel storage grids is commonly used. This achievement has improved the safety and quality of key nuclear power equipment, reduced the cost of construction, and is of great significance in promoting the development of China's nuclear industry equipment industry.
