First Fuel Loading Officially Begins at Tianwan Nuclear Power Plant Unit 7
On August 12, as the first fuel assembly was precisely and safely loaded into its designated position in the reactor core, the first fuel loading officially began at Unit 7 of the Tianwan Nuclear Power Plant, which is invested and controlled by China National Nuclear Corporation (CNNC)'s China Nuclear Power. This marks a solid foundation for subsequent reactor criticality and commercial operation. First fuel loading is the core procedure of implanting the "energy heart" into a nuclear reactor. As a key milestone in the full lifecycle of nuclear power construction, it not only serves as a comprehensive test of the unit's years of engineering construction quality, system commissioning level, and safety management capability, but also represents the critical starting point for the unit's nuclear-powered operation. It is understood that this fuel loading is the first-ever loading for a VVER-1200 unit in China, requiring a total of 163 nuclear fuel assemblies to be loaded...
