On December 16, the keel for the fifth (fourth serial) Project 22220 nuclear icebreaker Chukotka was laid on 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 latest historical past of the Baltic Shipyard there hasn’t been a collection of nuclear icebreakers like this, 5 vessels of the identical mission,” Alexei Kadilov mentioned within the opening speech. He thanked the enterprise personnel in addition to ROSATOM because the buyer for its belief.
The contract for the development of the third and 4th serial nuclear icebreakers was signed between FSUE Atomflot and the Baltic Shipyard in August 2019.
The icebreaker is supplied with specifically designed two new technology RITM-200 reactors and a steam turbine unit with an total energy capability of 175 MW. RITM-200 is an modern and distinctive design developed by of one of many oldest design bureaus of the nuclear business – OKBM Afrikantov (Nizhny Novgorod, a part of JSC Atomenergomash). The wealthy expertise of the development and operation of reactors for nuclear icebreakers in addition to trendy tendencies of the world nuclear energy engineering had been the idea for the design of RITM-200. It contains two reactors with the capability of 175 megawatts every. RITM-200 is nearly twice as gentle and compact as earlier reactors, subsequently it’s cheaper when it comes to materials depth and takes much less house on the vessel and thus extra economically environment friendly. Such an answer is structurally achieved as a result of the truth that steam turbines, which had been beforehand positioned outdoors the reactor, are actually positioned straight in it, which known as an built-in structure.
Main traits of the vessel: size: 173,three meters (160 m, dwl); width: 34 meters (33 m, dwl); top – 15.2 meters; energy capability: 60 mw (on propeller shafts); cruising pace: 22 knots (in clear water); draft – 10.5 meters/eight.65 meters; most ice penetration – 2.9 meters; displacement – 33 540 tons; estimated service life – 40 years; variety of crew – 53 individuals.
The 1st serial nuclear icebreaker “Sibir”, the 2nd serial nuclear icebreaker “Ural” and the third serial nuclear icebreaker “Yakutia” are underneath development on the Baltic Shipyard.
