The first RITM-200 reactor unit for the Project 22220 nuclear icebreaker "Leningrad" has undergone control assembly and is deemed ready for shipment and subsequent installation into the vessel's hull. The product was manufactured by machine builders of the Rosatom State Corporation at the ZiO-Podolsk plant.
The control assembly was the final stage of a multi-year production cycle. At this stage, all components of the reactor unit are assembled in their design position with high precision – down to thousandths of a millimeter. Following the inspection, engineers confirmed the product's compliance with design documentation and its readiness for operation with an estimated service life of at least 40 years.
The reactor belongs to the RITM-200 line, designed for modern nuclear icebreakers.
According to plant head Anton Lebedev, this unit is already the 13th in the series: previously, the enterprise manufactured ten RITM-200 reactors and two more powerful RITM-400 reactors. He noted that over the years, significant engineering experience has been accumulated and world-class competencies in the production of ship reactor units have been formed.
Earlier, "Pervy Tekhnichesky" reported that the government is working on mechanisms for extra-budgetary financing to complete the construction of the nuclear icebreakers "Leningrad" and "Stalingrad," as well as their support vessel. The price of the vessels jumped by 45% and now each costs 85 billion rubles.
