PJSC “Uralmashzavod”, part of the ”UZTM-Karteks” group is starting to manufacture metal-water protective tanks for the Project 10510 “Leader” nuclear icebreaker.
According to the company information release of January 11, a contract for the manufacture of protective metal structures worth 5.76 billion rubles was signed at the end of December by Sergey Tseluiko, general director of ”Zvezda” shipyard, and Yan Center, “UZTM-Karteks” director – general. “Uralmashzavod” will deliver two protective tanks (starboard and port) with a total weight of about 1,400 tons to the shipyard in Bolshoi Kamen in October 2023.
The metal-water protective tank consists of layers of metal, highly purified water and special concrete. The device is used to attenuate the ionizing radiation of the core of a nuclear reactor, which ensures the safe operation of the ship’s crew. Metal structures will be made of corrosion-resistant and high-strength steel of various thicknesses.
“We are grateful to the leadership of “Rosneft” and “Zvezda” shipyard for entrusting us with the manufacture of one of the most important components for the world’s largest nuclear-powered icebreaker,” Jan Center commented on the event.
Metal cutting for this new nuclear-powered icebreaker, named “Rossiya” (Russia), began in July 2020. The ship has the following characteristics: length – 209 m, width – 47.7 m, ice penetration (maximum) – 4 m, displacement approx. 69 700 t, power plant capacity – 120 MW (on shafts), cruise speed – 22 knots (in clear water)
