China Xuwu Unit 3 Plans First Concrete Pour for Nuclear Island

Recently, Unit 3 of the Phase I project of the Jiangsu Xuwu Nuclear Heating and Power Plant has finalized the plan for the first concrete pour of the nuclear island, marking an important preparatory milestone for the project construction. The unit is constructed and operated by CNNC Suneng Nuclear Power Co., Ltd., which is controlled and invested by China National Nuclear Power Co., Ltd. The project intends to advance the main construction of the nuclear island through this engineering milestone, while the actual implementation status remains subject to confirmation by subsequent engineering information. Regulatory licensing has provided the prerequisite for the relevant construction. The National Nuclear Safety Administration completed the review of the application documents, issued a construction license to Unit 3, and through on-site readiness supervision and inspection, confirmed that the conditions for the first concrete pour of the nuclear island foundation are met, allowing the relevant work to proceed. The license...

First Concrete Pour Completed for Nuclear Island of Unit 5 at China's Haiyang Nuclear Power Plant

Recently, the first concrete pour (FCD) for the nuclear island of Haiyang Nuclear Power Unit 5 was completed, with a cumulative concrete placement of 7,008 cubic meters, marking that the main works of the nuclear island have fully entered the construction phase and laying the foundation for the subsequent construction of Phase III of the Haiyang Nuclear Power Project. The nuclear island base slab of this unit is a raft foundation shared by Zone 5 of the reactor building, auxiliary building and annex building, adopting a cast-in-place reinforced concrete structure. The pouring operation was carried out in four stages and organized as a one-time monolithic pour. Shandong Nuclear Power, together with the supervision, general contracting and construction units, established a dedicated organizational structure to implement safety and quality management throughout the pouring process. The project team, drawing on experience feedback from Phase II, optimized construction organization and process interfaces to ensure continuous pouring of mass concrete.

The first concrete pouring for the nuclear island of Unit 2 of State Power Investment Corporation (SPIC) Guangxi Bailong Nuclear Power Project was successfully completed.

The first concrete pouring for the nuclear island of Unit 2 of SPIC Guangxi Bailong Nuclear Power Project was completed at 16:07 on September 30, after 69 hours and 40 minutes of continuous work. A total of 6,732.5 cubic meters of concrete was used for this pouring, marking another important milestone for the project after the FCD achievement for the nuclear island of Unit 1. Phase I of the Bailong Nuclear Power Project plans to build two CAP1000 nuclear power units. These two units adopt independently designed and domestically manufactured Generation III passive nuclear power technology, with each unit having a capacity of up to 1.25 million kilowatts. At present, Unit 1 has entered the construction and installation stage, and the steel containment vessel bottom head, CA20, CV1R, CA01...

First concrete poured for turbine building foundation of Unit 3 VVER-1200 at Leningrad NPP Phase II

On September 9, 2026, concrete pouring began for the foundation of the turbine building of Unit 3 VVER-1200 at Leningrad NPP Phase II in Russia. Construction workers have completed the pouring of the central section of the future foundation, with concrete consumption approaching 5,000 cubic meters. This pour is the first stage of construction of the foundation structure for this building. According to the plan, the contractor will use nearly 5,000 tonnes of rebar and more than 20,000 cubic meters of high-strength concrete to build a monolithic foundation slab 2.5 meters high and more than 8,000 square meters in area. The related operations are currently being carried out simultaneously in 7 construction zones. Konstantin Khudyakov, head of the Leningrad NPP project at TITAN-2 Holding (TITAN-2), said that the foundation construction of the turbine building places high demands on concrete quality, pouring technology and curing conditions, especially in the first few days after pouring, when it is necessary to focus on controlling on-site temperature and humidity and preventing mechanical damage. After the concrete reaches design strength, the contractor will, together with the owner, use non-destructive testing methods to inspect the structure, including ultrasonic testing; at the same time, specimens made from the same batch of concrete will also be subjected to compressive tests on a hydraulic press to confirm that the foundation is capable of bearing the loads of walls, floors, piping and large operating equipment.

First Concrete Pour Launched for Conventional Island of Jinqimen Nuclear Power Unit 2

At 22:16 on August 18, Zhejiang Jinqimen Nuclear Power construction reached another key milestone as the first concrete pour (FCD) for the raft foundation slab of the turbine generator building in the conventional island of Unit 2 was officially launched, marking the full commencement of the main construction of the conventional island of Jinqimen Nuclear Power Unit 2 and the project's official entry into the civil construction phase. The raft foundation slab being poured, as the core load-bearing structure of the conventional island, is a variable-cross-section, super-large-volume, waterproof and impermeable special concrete structure, and is the core section with the largest volume, most critical working conditions, and highest precision requirements among the conventional island raft foundation structures. This construction involves long continuous operation hours, stringent temperature control and crack prevention requirements, and significant construction organization challenges. To ensure the safe and high-quality completion of the project, CNNC Zheneng fully demonstrated the "owner" spirit, played the "backbone" role, and shouldered the "main force" responsibility, jointly establishing a dedicated technical task force with construction and supervision units, building on the mature FCD construction experience of Conventional Island Unit 1 to comprehensively optimize the raft construction process for Conventional Island Unit 2, strictly adhering to the highest quality standards and safety regulations for nuclear power construction.

First Concrete Pour Initiated for ECCS Sump of Units 1 & 2 at Gorakhpur Nuclear Power Plant, India

Nuclear Power Corporation of India Limited (NPCIL) announced on August 14 that the first concrete pour was initiated on the same day for the Emergency Core Cooling System (ECCS) sump of Nuclear Building-01 (NB-01) of Units 1 & 2 at the Gorakhpur Haryana Anu Vidyut Pariyojana (GHAVP) — the Gorakhpur Nuclear Power Plant, marking a phased milestone in the project's construction. Units 1 & 2 of the Gorakhpur Nuclear Power Plant are located in Gorakhpur Village, Fatehabad District, Haryana State, India, with two 700 MWe units planned, totaling 1,400 MWe in installed capacity. The pouring operation was carried out after addressing geotechnical and foundation-related challenges, pile foundation qualification, and obtaining necessary regulatory approvals.
