Russia Prepares New Floating Power Units for the Far North - How Project 20871 is Progressing

St. Petersburg-based "VNIIIR-Progress" has announced its participation in the construction project of a modernized floating power unit (MPEB) of "Atomflot" project 20871.

MPEBs of project 20871 are designed for operation in the regions of the Far North and the Far East. They will assist in the power supply of the Baimskaya ore zone, providing up to 106 MW of electricity to onshore grids. The power generated by the power unit is transmitted to the shore using 50 high-voltage cables.

Information about the characteristics of the MPEB project 20871 is already known. The vessel with a displacement of 21,261 tons from "Nevskoe PKB" will have two "RITM-200S" reactor plants with a nominal thermal power of 198 MW each. These reactors from "Rosatom" have an increased level of safety and high economic efficiency.

The interval between fuel reloads in them is about five years, which is almost twice as long as that of, for example, the floating nuclear power plant project 20870 "Akademik Lomonosov". Also, this MPEB will have two steam turbine units of 58 MW each.

Project 20871 has:

• greatest length — 143.3 meters;
• greatest width — 30 meters;
  
• hull height — 32 meters;
  
• draft — 5.5 meters;
  
• deadweight — 1507 tons.
  

Its operation will require a crew of 64 people. The unit can be operated for 40 years. On site, the new MPEBs will be held by rigid mooring devices that allow compensating for the movement of power units in the water during tides of approximately 5 meters.
