2025: Construction of the Leningrad AES-2 for 561 billion rubles
The Leningrad AES-2 will be built near St. Petersburg. According to preliminary estimates, the total cost of building two LAES-2 power units will amount to more than 561 billion rubles. By December 2025, the LAES-2 installed a console farm for the "melt trap" of the third power unit under construction. According to Konstantin Khudyakov, director of the program for the facilities of the Leningrad NPP of the Titan-2 concern, at the next stage the console farm will be supplemented with the necessary pipelines and temperature control sensors, after which the internal sections of the console farm will be concreted. Rosatom writes about this in December 2025.[1]
2021: The start of using a robot that can diagnose and repair wall cladding
In May 2021, it became known that the Leningrad NPP began to use a robot that has no analogues in the world. We are talking about a device that allows diagnosing and repairing the lining of the walls and the bottom of the fuel pools of power units with VVER-1200 reactors.
A fuel pool is a reinforced concrete structure with metal cladding filled with boric acid water. The integrity and tightness of the basin is an important component of the nuclear and radiation safety of the nuclear power plant.
The robot is equipped with a high-precision positioning and video surveillance system that allows it to "navigate" the pool without removing water and fuel. The robotic system is designed specifically for servicing nuclear power plants of a new type.
| Diagnostics and repair of pools at NPP is performed by personnel. To do this, you need to unload the fuel cells and drain the boron solution, - says the chief engineer of the Leningrad AES-2 Alexander Belyaev, whose words are quoted by the press service Rosenergoatom"" (this concern includes the Leningrad NPP). "It takes a few days. Our robot copes with such a task in a few hours. At the same time, there is no need to get fuel from the pool. |
Using ultrasound, the robot detects possible leaks, determines their coordinates, cleans the defective surface and repairs the metal lining by welding. The operator monitors and controls the entire process using a special panel.
If necessary, the robot will allow to quickly eliminate leaks in the fuel pool and maintain the design water level, preventing exposure and subsequent melting of fuel elements with fuel, minimizing manipulation with spent fuel.[2]
1966-1973
On November 29, 1966, the Council of Ministers of the USSR adopted Resolution No. 800-252 on the construction of the first stage of the LNPP, determined the organizational structure and cooperation of enterprises for the development of the design and construction of nuclear power plants:
supervisor - A.P. Alexandrov (I.E. Kurchatov); general designer - A. I. Gutov (VNIPIET); chief designer of the reactor plant - N. A. Dollezhal (NIKIET); chief designer of the turbine plant - Yu.F. Kosyak (KhTGZ); metal structure developer - N. I. Melnikov (TsNII PSK); the head material science organization - G. I. Kopyrin ("Promete"); designer and manufacturer of electromechanical equipment of CPS, KTO - Yu. G. Klaas (design bureau of the plant (Bolshevik)).
On June 29, 1967, the Scientific and Technical Council of the Ministry of Medium Engineering approved the technical design of the RBMK-1000 reactor submitted by NIKIET.
The excavator raised the first bucket of land from the foundation pit for the foundation of the main building of the future Leningrad NPP on July 6, 1967.
On December 23, 1973, the members of the State Acceptance Committee accepted the first power unit into operation. In 1975, the second unit of the Leningrad NPP was launched and the construction of the second stage of the station began.
