At the construction site of the Kursk NPP-2, the installation of the domed part of the outer containment shell of power unit No. 1 was completed Rosenergoatom, PUBLISHED 29.12.2022 At the construction site of the Kursk NPP-2, the installation of the domed part of the outer containment shell of the reactor building of power unit No. 1 was completed. First, the lower part of the dome was assembled - a large-sized structure weighing 235 tons. Five days later the upper part of the dome was assembled. Its weight is 175 tons, and its diameter is 34.7 meters. Now the height of the structure is 65.4 meters. "The outer containment is one of the most important security systems. This reinforced concrete structure protects the reactor plant from extreme external influences. In addition to the outer, there is also an inner protective shell that provides reliable protection of the environment. Its device was completed in October this year. The double containment is a distinctive feature of the Russian design of power units with PWR-1200 and PWR-TOI reactors, which ensures the maximum level of nuclear power plant safety," said Andrey Osharin, first deputy director for construction of new units at the Kursk NPP. The installation was preceded by a pre-assembly of the components of the platform, which was performed on a special site on the ground. This made it possible to provide the high quality of work. "The stage of preparation and assembly of the NZO dome is a long and painstaking process; according to the plan, it takes 175 days. At the construction site of the Kursk NPP-2, the assembly of two parts of the dome was completed by specialists in 135 days. The reduction in terms was achieved thanks to the well-coordinated interaction of specialists at the construction site and the organization of work with the maximum parallelization of operations," said Evgeny Shevchenko, director of the Kursk branch of Trest RosSEM LLC. The assembly and installation of the dome was performed by specialists from the Kursk branch of Trest RosSEM LLC (part of the Engineering Division of Rosatom). "Successful completion of the installation of the outer containment dome is an important step towards the physical start-up of the power unit," commented Oleg Shperle, vice president of JSC Atomstroyexport, project director for the construction of Kursk NPP-2. "Concreting work on the dome will begin next spring, and after this stage is completed, it will be possible to proceed with the installation of passive heat removal systems (PHRS)." The construction of power unit 1 and 2 of the Kursk NPP-2 is performed as part of the federal project "Design and construction of reference power units of nuclear power plants" of the Integrated Program "Development of equipment, technologies and scientific research in the sphere of the use of atomic energy in the Russian Federation for the period up to 2024.
