The Soviet Ship That Cuts Through Ice Like a Nuclear-Powered Knife Through Butter | Danger Room | Wired.com: "This ship is powered by dual pressurized-water nuclear reactors, each of which contains 245 enriched uranium fuel rods. When fully loaded with 500kg of nuclear material, the Yamal can operate for up to five years without needing to refuel. Each reactor weighs 160 tons and resides within a closed compartment under reduced pressure and is shielded by steel, high density concrete and water. 86 sensors throughout the ship monitor radiation levels at all times."
