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.

Russia's Leningrad NPP resumes hot water supply to Sosnovy Bor

On August 31, 2026, Russia's Leningrad NPP resumed hot water supply to the city of Sosnovy Bor via the district heating station (BRT) after completing scheduled maintenance. Dmitry Tsygankov, workshop manager of the turbine department at Leningrad NPP, stated that the plant had successfully completed BRT-related maintenance work in August, including chemical cleaning of heat exchange equipment, overhaul of pumping equipment, industrial safety assessments, and the necessary hydraulic pressure tests of pipelines. He said that the BRT is now supplying hot water to the city and industrial zone as planned, and the plant is preparing for the scheduled start of the Sosnovy Bor heating system; the heating system will be put into operation once outdoor temperatures drop to the appropriate level.

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

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 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...

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.
