Russia is building a new generation of icebreakers that will break ice up to 2.8 meters (9.18 feet).
Named ‘Arktika‘, the first Project LK-60 nuclear-powered icebreaker got its two reactors assembled in November 2015. Two RITM-200 nuclear reactors will produce more than 170 megawatt.
With an overall length of 173 metres and breath of 34 metres, the Project LK-60 draught is 10.5m and a minimum operating draught of 8.55m. Its has ability to sail both in Arctic waters and mouth of polar rivers and has a displacement 33,544 tons. The 75-man crew will enable the icebreaker to break ice at speed up to 1.5 to 2 knots.
Designed to break ice in the Northern Sea Route, the Project LK-60 will keep the commercial route open on a year-long basis. Its main task will be to escort large commercial ship along high-latitude routes, north of all the archipelagos. It will also have a rescue ship role due to its ability to sail all-year round.
The Project LK-60 can fill ballast tanks with water and settle on 2 meters, becoming very heavy. When approaching a river mouth and discharging its ballast water, the nuclear-powered icebreaker rises and can work as a shallow-draft icebreaker.
The RITM-200 nuclear reactor
On Afrikantov OKBM’s website, the RITM-200 builders, we can read that “it is a new project «RITM 200», a two-reactor RP with capacity of 170 megawatt (Capacity of KLT unit used in modern nuclear icebreakers is 140-150 megawatt). «RITM 200» is almost twice easier and more compact, accordingly, it is cheaper on material consumption and occupies less place on a vessel; consequently, it is more cost-effective. Structurally such solution is attained due to an arrangement of heat exchangers directly in the reactor (integral layout) whereas earlier they were settled down out of it.”

Russia is building a great fleet of icebreakers, leading the Arctic countries in that capability. With the Northern Sea Route and the availability of many untapped natural resources, the Project LK-60 will become a vital element of Russian Arctic operations.
Its capabilities will definitely contribute to strengthen the Russian economy and keep Russia’s new commercial route open for business.
