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...

Installation of STT153A Tower Crane Completed at Jiangsu Xuwei Nuclear Heating and Power Plant by CEEC

On August 6, the installation and commissioning of the first special equipment STT153A tower crane was successfully completed for Section A of the natural draft cooling tower construction and installation project for Units 1, 2, and 3 of Phase I of the Jiangsu Xuwei Nuclear Heating and Power Plant, undertaken by CEEC Mechanization Company. The tower crane installed this time was manufactured by Fushun Yongmao Construction Machinery Co., Ltd., and is positioned at the rebar processing yard of the 1PB cooling tower, with a maximum rated lifting capacity of 10t. The jib length for this installation is 65m, and the standard section height is 37.5m. Based on the on-site machinery configuration, the installation of this tower crane was completed with the coordination of one 130t mobile crane and one 25t mobile crane. The technical team of the CEEC Mechanization Xuwei Project Branch, prior to the formal commencement of the tower crane installation...

Cold Functional Test of Tianwan Nuclear Power Plant Unit 8 Successfully Completed

On August 3, the cold functional test (hereinafter referred to as the "cold test") of Tianwan Nuclear Power Plant Unit 8, constructed by China Nuclear Industry 23 Construction Co., Ltd. (CNI23), was successfully completed, marking the official transition of the unit from the engineering installation phase to the system commissioning and testing phase, laying a solid foundation for subsequent hot functional test, reactor fuel loading, and grid connection. The cold test is the first comprehensive commissioning test after a nuclear power unit enters the system commissioning phase and is one of the important milestone nodes in nuclear power plant engineering construction. Its main purpose is to verify the integrity and leak-tightness of the pressure boundary, including primary loop pipeline welds, equipment, and high-pressure sections of connected systems, comprehensively inspect on-site installation quality, and precisely identify potential hazards. It serves as the first comprehensive and systematic "physical examination" of the reactor before its operation.

Ministry of Ecology and Environment's North China Nuclear and Radiation Safety Supervision Station Conducts Special Supervision on Cold Test Release for Tianwan Nuclear Power Unit 8

The Cold Functional Test (hereinafter referred to as the cold test) is the first major comprehensive test for a nuclear power unit transitioning from the installation phase to the commissioning phase. It is a key core link to verify the pressure-bearing capacity and sealing performance of the nuclear island main system and equipment under design pressure conditions, and serves as a critical milestone to ensure the subsequent safe and stable operation of the unit. Recently, the Ministry of Ecology and Environment's North China Nuclear and Radiation Safety Supervision Station (hereinafter referred to as the North China Supervision Station) conducted comprehensive supervision on the cold test control point release for Tianwan Nuclear Power Plant Unit 8. Adhering to the principle of supervision moving forward, the station consolidated the pre-test foundation. Upholding the nuclear safety supervision philosophy of "prevention first, moving the checkpoint forward," the North China Supervision Station focused on the preconditions for the cold test control point release, verified various items pending rectification one by one, and ensured that all hidden dangers were effectively addressed, building a solid safety barrier for the smooth progress of subsequent tests.
