St. Petersburg-based VNIIR-Progress has announced its participation in the construction project of a modernized floating power unit (MPEB) of Atomflot project 20871.
The delivery will include main distribution devices, shore power panels, power distribution panels, emergency generator panels, reactor plant panels, and 110V uninterruptible power supplies. The development and manufacture of distribution devices are carried out in the shortest possible time in order to deliver the equipment to the shipyard in December 2024.
MPEBs of project 20871 are designed for operation in the regions of the Far North and the Far East. They will help 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 much as, for example, the floating nuclear heat and 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;
- board height — 32 meters;
- draft — 5.5 meters;
- deadweight — 1507 tons.
Its operation will require a crew of 64 people. The installation 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.
