Russia is this week celebrating the historic achievements of its
nuclear-powered icebreaker fleet and has also announced project milestones for its latest vessels. The Arktika was the first surface vessel to reach the North Pole, on 17 August 1977. The seventh and largest Arktika class icebreaker — 50 Years of Victory — entered service in 2007 and is now on its way to the North Pole to commemorate the 40th anniversary of the Arktika’s expedition.
50 Years of Victory — which is 25,800 dwt, 160 m long and 20 m wide, and is designed to break through ice up to 2.8 m thick — left the port of Murmansk on 13 August. It aims to reach the North Pole on 17 August when the Russian Federation flag will be hoisted in memory of the Arktika’s pioneering captain, Yury Kuchiyev, and his crew.
During the expedition, the icebreaker will host a conference dedicated to the future of the Arktika fleet, environmental protection of the Arctic region and the development of
50 Years of Victory is scheduled to return to port on 23 August.
Atomflot, a subsidiary of Russian state nuclear corporation Rosatom, said yesterday that Kuchiyev’s achievement was comparable to “the first human’s journey into outer space”, referring to Yury Gagarin’s orbit of the Earth in the Vostok spacecraft on 12 April 1961.
“The Arktika expedition, which took seven days and eight hours to complete and crossed 2528 miles, practically proved the possibility of
Rosatom’s nuclear fuel manufacturer subsidiary TVEL has announced its delivery of a batch of fuel assemblies for a universal nuclear icebreaker of the new generation of Arktika. The fuel assemblies, which were produced by TVEL’s Chepetsky Mechanical Plant (ChMZ), consist of “seamless
They are a “unique and exclusive technology”, which ChMZ have produced for the first time, together with scientists from the AA Bochvar Research Institute of Inorganic Materials (VNIINM), which is another Rosatom subsidiary. The fuel assemblies will be assembled by TVEL’s Mashinostroitelny Zavod (Elemash) plant. The fuel is intended for use in RITM-200 reactors.
In January 2013, Rosatom called for bids to build two more of these universal icebreaker vessels (project 22220), for delivery in 2019 and 2020, and in May 2104 a contract for RUB84.4 billion was signed with United Shipbuilding Corporation. In August the same year, Russian regulator Rostechnadzor licensed Baltijsky Zavod Shipbuilding to install the RITM-200 reactor units from OKBM Afrikantov for the pilot model. The keel of the first, Arktika, was laid in November 2013, and that of the second, Sibir, in May 2015.
RITM-200 reactors have 175 MWt each and are deigned to deliver 60 MW at the propellers via twin
