Atomenergomash Group's Venta supplies equipment for world's largest icebreaker Arktika
Sverdlovsk region, Russia based Nizhneturinsky Engineering Works "Venta" (part of Rosatom Group) has manufactured and shipped the equipment for multipurpose nuclear-powered icebreaker "Arktika". The world's largest vessel of this class was launched in St. Petersburg, the Sverdlovsk regional government press office said. The shipped cargo includes two steam turbines manufactured by Ural Turbine Works (UTZ).
The Ministry of Industry and Science of the Sverdlovsk region said VENTA has manufactured for the icebreaker four vapor-air mixture coolants. The coolant is designed for steam/air mixture bleeding in the radiation monitoring system. Each unit is equipped with valves and instrumentation. The scope of supply includes a set of spare parts.
Baltiysky Zavod was contracted to build three nuclear-powered icebreakers of “Arktika", “Siberia" and "Ural" series for FSUE Rosatomflot. The three nuclear-powered icebreaker (Project 22220) are being built to RS class. The newbuilding orders were placed by State Corporation Rosatom.
The nuclear-powered icebreaker Arktika of LK-60 new generation (Project 22220) was launched at St. Petersburg based Baltiysky Zavod - Shipbuilding.
The icebreaker's propulsion includes two RITM-200 nuclear reactors, with a thermal capacity of 175MW each, using enriched uranium-235 fuel (20%) to deliver 60MW of energy to drive the electric propellers. The integrated steam-turbine plant will include two main turbo-generators, each with a capacity of 36MW, and feature a regulation system and generator, feeding, condensate and circulatory pumps, and other ancillary equipments. The vessel's electric propulsion equipment will include two voltage generators of 36MW each, three propulsion motors of 20MW each, frequency converters for controlling the propulsion motors, associated transformers and a 10kV switchgear.
The icebreaker contract is valued at about RUB 37 billion. Sea trials and commissioning with the Rosatom fleet of the icebreaker is scheduled in late 2017.
General characteristics: length overall - 173.3 m (DWL), beam molded - 34 meters (DWL), draft (DWL) - 10.5 m; minimum loaded draft - 8.55 m, displacement - 33.54 tonnes; capacity - 60 MW, operational speed - 22 knots (clean water), depth - 15.2 m; icebreaking capability - 2.8-meter-thick ice; designated service life - 40 years.
Detailed design was developed by CDB "Iceberg" in 2009.The LK-60 icebreaker features advanced double-draft capability, which makes it suitable for operations both in the Arctic waters, and in the mouths of the northern rivers. The icebreaker will be operating in the western region of the Arctic, the Barents, Pechora and Kara Seas and in shallow waters of the mouth of the Yenisei and the Ob Bay.
JSC Venta is a subsidiary of Atomenergomash Group, a power engineering division of the Rosatom Corporation.
