What kind of lump? The brand new nuclear icebreaker RFS Sibir is currently on a delivery voyage from the Baltic Sea in the direction of Murmansk. It is part of Russia's overall strategic concept in the Arctic. The Sibir was launched on 22 September 2017. The ship has since been handed over to the operator Rosatomflot. The ship left St. Petersburg on 13 January and is on its way to Murmansk. It passed the Fehmarnbelt on 15 January and left the Skagerak on 17 January.
The Sibir is a nuclear-powered icebreaker of the LK-60 class. It is powered by two RITM-200 pressurised water reactors, each with an output of 170 MW. The service life is designed for 40 years. It has four steam generators and the fuel enrichment is below 20%. This means it can run for many years without refuelling. The KL-60 class icebreakers can break through ice up to 3 metres thick and will be able to operate in the open sea as well as in rivers.
The sister ships are called Arktika (already completed), Jakutija and Ural. The latter will be handed over to the operator at the end of 2022.
