The Sevmorput, unique bouquet The world’s largest operational nuclear cargo ship, it remains in service more than three decades after its construction in the Soviet era, playing a key role in Russia’s Arctic strategy.
This 260.3-metre-long giant, capable of carrying up to 61,000 tonnes, was designed to navigate the difficult conditions of the North Sea, taking advantage of the autonomy provided by its 135 MW KLT-40 nuclear reactor.

Built in 1988, the Sevmorput is heir to a tradition dating back to the late 19th century, when the Russian Empire began developing icebreakers to explore Arctic routes.
The ship has faced numerous challenges since its launch, including docking restrictions in Soviet ports following the Chernobyl accident and a long period of inactivity.
In 2015, after a refit, the ship was put back into operation under the control of Atomflot, a subsidiary of the state corporation Rosatom, although it was not without technical problems such as the failure of a propeller in 2020.
Currently moored in Murmansk, the Sevmorput remains in active service, attracting international attention, especially during its transits near European coasts.
