Ministry of Ecology and Environment North China Regional Office of Nuclear and Radiation Safety Supervision Conducts Supervision of First Fuel Loading at Tianwan Nuclear Power Plant Unit 7

Recently, the first fuel loading of Unit 7 at Tianwan Nuclear Power Plant was officially initiated, with the first fuel assembly successfully loaded into the reactor core, marking the unit's formal transition into the commissioning phase with nuclear operation. This unit is a key cooperative project witnessed by the heads of state of China and Russia via video link at its groundbreaking ceremony. This fuel loading marks a significant milestone achievement in the largest strategic cooperation project in China-Russia nuclear energy cooperation. As a core and critical procedure in nuclear power engineering, the first fuel loading serves as a comprehensive and holistic verification of the unit's engineering construction quality, system commissioning effectiveness, and safety control capabilities, and is of decisive significance to the subsequent safe and stable operation of the unit. The Ministry of Ecology and Environment North China Regional Office of Nuclear and Radiation Safety Supervision (hereinafter referred to as the North China Regional Office) has consistently upheld the nuclear safety regulatory work style of "rigorous, prudent, meticulous, and practical," closely focusing on the core and critical aspects of the first fuel loading, and implementing full-coverage, full-chain, and whole-process supervision and control over this fuel loading operation, effectively safeguarding the safety and quality defense line of the loading operation.

Xu Dabao Nuclear Power Plant Completes On-Site Comprehensive Emergency Exercise Before First Fuel Loading of Unit 3

On August 20, Liaoning Nuclear Power conducted an on-site comprehensive emergency exercise before the first fuel loading of Unit 3, honing nuclear emergency response capabilities through practical drills. The exercise was carried out under the full guidance and supervision of the Northeast Regional Office of Nuclear and Radiation Safety Supervision under the Ministry of Ecology and Environment, with a total of over 300 participants from Liaoning Nuclear Power, the supervision company, the general contractor, and various construction units. The exercise successively completed responses across all emergency preparedness levels, including emergency standby, building emergency, site area emergency, and off-site emergency, with plant recovery efforts initiated during the emergency termination phase. The exercise activated key emergency facilities such as the emergency command center, mobile power garage, and fire station, comprehensively testing the organizational command, comprehensive response, and multi-party coordination capabilities of Liaoning Nuclear Power's nuclear emergency system, as well as the reliability and availability of various emergency facilities and equipment.

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...
