Обслужит атомоходы, перевезёт радиоактивные отходы — что известно про МСАТО проекта 22770

The MSATO (multifunctional nuclear technology service vessel) was developed under Project 22770 by the Iceberg Central Design Bureau. It is designed for technological and technical maintenance of nuclear power plants of Russian marine vessels and will replace the Imandra vessel of Project 1948, which performs similar functions, in 2029.

According to the Iceberg Central Design Bureau, the future vessel under the project will receive a diesel power plant. Among the main characteristics of the MSATO:

• greatest length — 158.80 m;
• length along the waterline — 149.20 m;
  
• greatest width — 26.00 m;
  
• board height at midship — 10.50 m, height at full draft displacement — 7.50 m;
  
• full displacement of the vessel — 22,661 tons;
  
• power of the main power plant on the shafts — 9,200 kW;
  
• speed — 12 knots;
  
• crew — 15 people;
• ice reinforcement class of the hull — Arc5.
  

MSATO will be engaged in:

• receiving, preparing and loading fresh nuclear fuel into reactors;
• unloading and transporting spent fuel, liquid and solid radioactive waste until it is sent for processing;
  
• storage of reloading equipment;
  
• revision of reactor plant equipment during reloading;
  
• ensuring the efficient operation of existing, under construction and future icebreakers and other facilities with reactor plants.
  

Its service area will be the western and eastern regions of the Arctic, including the Barents, White, Pechora, Kara Seas, the Laptev Sea, East Siberian, Chukchi, Bering, Okhotsk Seas, and the northern part of the Sea of Japan. However, it is noted that the vessel has an unlimited area of operation.
