Nuclear-powered icebreaker "Leningrad" completes installation of two RITM-200 reactors

Nuclear-powered icebreaker "Leningrad" completes installation of two RITM-200 reactors

United Shipbuilding Corporation (USC) announced that Baltic Shipyard has completed the installation of two RITM-200 nuclear reactors on the Project 22220 nuclear-powered icebreaker "Leningrad". The "Leningrad" is the sixth vessel in the Project 22220 nuclear-powered icebreaker series. The vessel is being built by Baltic Shipyard under an order from Rosatom, and its keel-laying ceremony was held on January 26, 2024. Project 22220 nuclear-powered icebreakers are primarily designed to ensure year-round navigation in the western Arctic waters of Russia. Equipped with nuclear propulsion systems, these vessels can perform icebreaking escort and fairway maintenance missions under complex ice conditions.

Unit 2 of Leningrad Nuclear Power Plant Phase II automatically shut down for equipment maintenance

Unit 2 of Leningrad Nuclear Power Plant Phase II automatically shut down for equipment maintenance

At 21:45 local time on August 8, 2026, Unit 2 of Leningrad Nuclear Power Plant Phase II was shut down by the automatic system due to the need for thermal-mechanical equipment maintenance. After the maintenance work is completed, the unit will be reconnected to the grid. The shutdown was carried out in accordance with established procedures and design logic. The plant reported no violations of safe operation limits or operating conditions for any of the units. Currently, RBMK-1000 Units 3 and 4 of Leningrad Nuclear Power Plant, as well as Unit 1 of Phase II, are operating normally and carrying electrical loads in accordance with the dispatch schedule. RBMK-1000 Units 1 and 2 are in the preparation stage for decommissioning...

Construction of inner containment begins at Unit 4 of Leningrad Nuclear Power Plant II

Construction of inner containment begins at Unit 4 of Leningrad Nuclear Power Plant II

Construction of the inner containment of the reactor building at Unit 4 of the Leningrad Nuclear Power Plant II in Russia has commenced. The unit features a VVER-1200 reactor, and the inner containment is a key component of the unit's passive safety system, as well as part of the plant's confinement safety system. Construction workers have installed the first tier of vertical sealed steel liner to its design position. The steel structure weighs approximately 97 tonnes, and the lifting and positioning operations were carried out using a heavy crawler crane, with the entire installation process lasting about 7 hours. The contractor, TITAN-2 Holding Company, stated that the preparatory work took several months, including component fabrication, protective coating application, on-site assembly and welding, and structural quality inspection...

Moscow Cable Company Shield to Supply 4 km of Busbar Trunking for Units 3 and 4 of Leningrad NPP Phase II

Moscow Cable Company Shield to Supply 4 km of Busbar Trunking for Units 3 and 4 of Leningrad NPP Phase II

Moscow Cable Company (Shield) will supply four kilometers of transmission lines for the Leningrad Nuclear Power Plant. The company will manufacture 10 kV and 24 kV generator voltage transmission lines for Units 3 and 4 of Leningrad NPP Phase II. These transmission lines meet the highest reliability and safety requirements of the nuclear industry and are equipped with current transformers and voltage transformers produced by Cable Shield Company. The transmission lines will be manufactured at the enterprise in the city of Kovrov, where new production capacity for cable trays was built last year. Currently, the plant's annual production capacity reaches 12,000 meters of cable trays. According to statistics, over 400,000 meters of transmission lines produced by the company have been put into operation...

Unit 4 of Leningrad NPP Phase II completes installation of first major equipment

Unit 4 of Leningrad NPP Phase II completes installation of first major equipment

Unit 4 of Russia's Leningrad NPP Phase II recently completed the installation of the core melt catcher vessel. This is the first major equipment of the unit to enter the installation stage, and also the first passive safety system equipment to be installed. The steel structure weighs 157 tonnes, and the installation was carried out using a heavy crawler crane, taking about one work shift of approximately 8 hours, nearly 3 months ahead of the original schedule. Valery Zhemchugov, Acting Director of Leningrad NPP, stated that the installation of the core melt catcher vessel is a key milestone in the construction of Unit 4, a VVER-1200 pressurized water reactor unit, and that the relevant work was completed in accordance with quality requirements, providing more time for subsequent reactor building civil and installation works.

Russia Completes Manufacturing of Second RITM-200 Reactor Unit for Leningrad Nuclear-Powered Icebreaker

Russia Completes Manufacturing of Second RITM-200 Reactor Unit for Leningrad Nuclear-Powered Icebreaker

On July 29, Rosatom's ZiO-Podolsk Mechanical Plant in the Moscow Region completed the manufacturing of the second RITM-200 reactor unit for the Leningrad nuclear-powered icebreaker. With this, the manufacturing of all major equipment for the reactor compartment of this under-construction 22220-type universal nuclear-powered icebreaker has been fully completed. The Leningrad nuclear-powered icebreaker began construction in January 2024. The naming of the vessel is linked to the 80th anniversary of the lifting of the Siege of Leningrad, with veterans and survivors of the siege proposing that this new-generation nuclear-powered icebreaker be named Leningrad. Following Rosatom's tradition of naming reactor units, the two completed reactor units of the Leningrad have been named "Iskra" and "Grom," commemorating the operations that broke and ultimately lifted the Siege of Leningrad between 1943 and 1944.
