Fuel Loading Completed for Tianwan Nuclear Power Plant Unit 7, Entering Commissioning Phase with Nuclear Fuel
On August 18, with the completion of core loading correctness verification and the commencement of protective tube assembly reinstallation, the first nuclear fuel loading work for Unit 7 of the Tianwan Nuclear Power Plant in Lianyungang, Jiangsu Province, was successfully concluded, marking the entry into the commissioning phase with nuclear fuel. This laid a solid foundation for subsequent reactor criticality, grid connection, and commercial operation of the unit. Fuel loading is a key milestone in the entire lifecycle of nuclear power plant construction and a critical starting point for the unit's operation with nuclear fuel. Unit 7 of the Tianwan Nuclear Power Plant is the first VVER-1200 Generation III nuclear power unit to be constructed in China, and this fuel loading also marks the first-ever fuel loading for a VVER-1200 type nuclear power unit in China. The loading process commenced on the 12th and was fully completed by the 18th, with a total of 163 nuclear fuel assemblies loaded.

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...
