On December 16, the keel for the fifth (fourth serial) Project 22220 nuclear icebreaker Chukotka was laid at the Baltic Shipyard in St Petersburg.
Roman Kopin, the Governor of the Chukotka Autonomous Okrug, Alexey Likhachev, Director General of Rosatom, Evgeny Elin, Vice Governor of St. Petersburg, Vyacheslav Ruksha, Deputy Director General and Director of the Northern Sea Route Directorate of Rosatom, Vladimir Egorov, Deputy Director of nuclear ships Department of Russian Maritime Register of Shipping, David Adamia, Vice President of the United Shipbuilding Corporation, Mustafa Kashka, Director General of FSUE Atomflot and Aleksey Kadilov, Director General of the Baltic Shipyard attended the ceremony.
“In recent history of the Baltic Shipyard there hasn’t been a series of nuclear icebreakers like this, five vessels of the same project,” Alexei Kadilov said in the opening speech. He thanked the enterprise personnel as well as ROSATOM as the customer for its trust.
The contract for the construction of the 3rd and 4th serial nuclear icebreakers was signed between FSUE Atomflot and the Baltic Shipyard in August 2019.
The icebreaker is equipped with specially designed two new generation RITM-200 reactors and a steam turbine unit with an overall power capacity of 175 MW. RITM-200 is an innovative and unique design developed by of one of the oldest design bureaus of the nuclear industry – OKBM Afrikantov (Nizhny Novgorod, part of JSC Atomenergomash). The rich experience of the construction and operation of reactors for nuclear icebreakers as well as modern trends of the world nuclear power engineering were the basis for the design of RITM-200. It includes two reactors with the capacity of 175 megawatts each. RITM-200 is almost twice as light and compact as previous reactors, therefore it is cheaper in terms of material intensity and takes less space on the vessel and thus more economically efficient. Such a solution is structurally achieved due to the fact that steam generators, which were previously located outside the reactor, are now located directly in it, which is called an integrated layout.
Main characteristics of the vessel: length: 173,3 meters (160 m, dwl); width: 34 meters (33 m, dwl); height – 15.2 meters; power capacity: 60 mw (on propeller shafts); cruising speed: 22 knots (in clear water); draft – 10.5 meters/8.65 meters; maximum ice penetration – 2.9 meters; displacement – 33 540 tons; estimated service life – 40 years; number of crew – 53 people.
The 1st serial nuclear icebreaker “Sibir”, the 2nd serial nuclear icebreaker “Ural” and the 3rd serial nuclear icebreaker “Yakutia” are under construction at the Baltic Shipyard.
