Localization of nuclear fuel components in Guangdong Ling'ao nuclear power plant

It was learned from Guangdong Nuclear Power Group that China's first batch of full M5AFA3G fuel assemblies was officially delivered to the Ling Ao Nuclear Power Plant. This is one of the improvements in the core design of China's million kilowatt nuclear power unit, marking a new level of localization of China's high fuel consumption fuel assembly manufacturing.

The full M5AFA3G fuel assembly is one of the world's most advanced nuclear fuel components. This technology has been mastered by developed countries such as Europe and the United States. The use of new nuclear fuel assemblies is also an important part of the implementation of the 1/4 refueling technology in the first phase of the Ling Ao Nuclear Power Plant. At present, China's nuclear power plants use 1/3 refueling technology, which replaces one-third of the entire reactor fuel assembly every year to maintain the full power of the reactor. Since the new nuclear fuel assembly can greatly improve the fuel consumption and corrosion resistance of the fuel, it can improve the average fuel consumption of the components and improve the economics of the fuel assembly.

According to estimates, the two units of the Ling Ao Nuclear Power Plant use new fuel assemblies. After implementing 1/4 refueling, the annual fuel cost can be saved by about 20 million US dollars.
