Background

The floating nuclear power units will be located near the village of Pevek in the Chaunskaya Bay, in Chukotka region. The project is developed by Atomflot, a subsidiary of Rosatom, and is intended to supply power to the Baimsky mining and processing plant located 450km away from the project site.

Atomflot will supply four modernized floating power units with an installed capacity of 106 MW each, with the planned commissioning of the first two power units by early 2027, the third by early 2028, and the fourth by early 2031.

The total investment was estimated at 150 billion roubles (ca US$ 2 billion). Another source from 2021 refers to the project cost of 190 billion roubles (ca US$ 2.5 billion).

Unit Technology

The floating nuclear power vessels are designed by Rosatom and supplied by Atomenergomash. They are self-contained, low-capacity, floating nuclear power plants. In September 2019, Russia’s first-floating nuclear power plant, the smaller Akademik Lomonosov nuclear power plant, arrived to its permanent location, which is also in the Chukotka region.

In December 2021 Rosatom announced that the four units will carry a new, slightly improved version of RITM-200 cores, named RITM-200S. TVEL was charged with development of the new fuel assemblies for its improved core. Three floating units will be used for operations and one will be held in reserve for use during repairs or refuelling. The first two reactors were already under construction by Atomenergomash, as of July 2021.

In August 2022, construction of the first hull started in China, planned to be delivered to Russia by the end of 2023 for installation of reactors and other equipment. Because of the tight deadlines for the implementation of the project and the heavy workload of domestic shipbuilding enterprises, it was decided to manufacture hulls for the first two power units at a foreign shipyard. The barge will measure 140 metres long and 30 metres wide, according to Rosatom, and will feature structures for containment and radioactive waste storage as well as fuel tanks for diesel. On delivery to Atomenergomash by the end of 2023, the barge will weigh 9549 tonnes and when fitted out with two RITM-200S pressurised water reactors and all the equipment, it will weigh some 19,088 tonnes. The reactor components were already being manufactured, as of August 2022.

The construction scheme and the shipyard-builder of the hulls of the third and fourth units were to be decided on by the end of 2022.

Offtake

The four units will supply energy via a 500km transmission line to the Peschanka region. About halfway to Peschanka there is also the Bilibino nuclear power plant. In autumn 2021, Atomflot and GDK Baimskaya (controlled by Kaz Minerals) signed a preliminary agreement for the supply of electricity to the Baimsky mining and processing plant. Baimsky is one of the world's largest mineral deposits and is rich in copper and gold. The development of the remote site in Russia's eastern Chukotka region demands a complex multi-partner regional plan involving the Russian government, the regional government and developers KAZ Minerals.

Construction Delays

In November 2022 it was reported that the project is likely to be delayed by one year to 2028, due to delays of the completion of the Baimsky mining and processing plant.
