en.Wedoany.com Reported - The concrete pouring of the reactor building foundation slab for Unit 3 of the Kursk NPP-2 project has been successfully completed ahead of the original schedule. The construction work lasted four months, with the Engineering Division of Rosatom State Corporation serving as the general designer and general contractor.
The construction team mobilized approximately 200 workers to pour concrete for the foundation slab, which covers an area of 5,400 square meters. Every stage of the pouring process was subject to multi-level quality control, with an expert team conducting real-time monitoring of dozens of key parameters daily.
Alexander Uvakin, Director of the Kursk Nuclear Power Plant, stated that the safety and stability of the nuclear power plant depend entirely on the robustness of its foundation, and he thanked the entire team for completing this critical objective ahead of schedule to the highest standards.
Alexander Khazin, Project Director for Units 3 and 4 of the Kursk NPP-2 project, noted that the completion of the foundation concrete pouring marks the achievement of a key construction milestone. The next steps will involve the installation of reinforcement modules and the start of concrete pouring for the reactor building walls, officially commencing the vertical construction phase of the reactor building walls.
Currently, the Kursk NPP-2 project is advancing the construction of Units 2 and 3 simultaneously. In late April this year, the project's first VVER-TOI unit—the nuclear power unit with the largest single-unit capacity in Russia—officially entered commercial operation. Since its grid connection at the end of 2025, it has generated a cumulative total of 1.6 billion kilowatt-hours of electricity. According to Russia's General Scheme for the Development of the Energy Sector, a total of four new units are planned for this site, with a total installed capacity of 5,000 MW. Once completed, the site will fully transition to next-generation reactor technology. The construction of the four VVER-TOI units at Kursk NPP-2 has been included in the General Scheme for the Siting of Electric Power Facilities until 2042, approved by the Government of the Russian Federation in December 2024.
The construction team plans to maintain the current work pace to prepare for another key milestone this year—the installation of the first components of the reactor building's inner containment.
