TSAMTO, May 5. Specialists of the Baltic Plant (part of the USC) made a unique loading of a block section weighing 220 tons on board the nuclear icebreaker "Yakutia" project 22220.
The protective shell, consisting of 8 sections with a total weight of 220 tons, was loaded on board the vessel in 8 hours. The minimum weight of one section is 30 tons, the maximum is 33 tons. In parallel, the loading of the onboard section weighing 53 tons was carried out . Due to the complexity of the work carried out, four cranes had to be used simultaneously to successfully complete the task.
The protective shell of the reactor compartments is a kind of "sarcophagus" that ensures safety for the reactor maintenance personnel during its operation. The block section consists of various materials – concrete, steel and special protective metals, which significantly weights the structure and creates certain difficulties during loading.
Specialists of the Baltic Plant, thanks to the experience, well-coordinated work of crane operators and the professionalism of slingers, managed to load the block section according to the work plan.
The universal nuclear icebreaker Yakutia is the fourth vessel of the 22220 project, which is being built at the Baltic Plant by order of the Rosatom State Corporation. The vessel was laid down on the slipway of the plant on May 26, 2020.
The universal nuclear icebreakers of Project 22220 are the largest and most powerful icebreaking vessels in the world. Their main task is to ensure year–round navigation in the Arctic. The vessels of this project in the coming years should become the basis of the civil icebreaking fleet of Russia.
