Russia completes second reactor for Arctic floating nuclear plant

Russia has completed the second RITM-200S reactor at the ZiO-Podolsk factory, marking a major milestone for the PEB-106 floating nuclear power plant. This vessel is designed to provide a stable electricity supply to a massive copper mining hub in the Russian Far East.

The two reactors, the second of which passed high-pressure water trials and assembly tests, will form the energy core of the PEB-106. This technology is an adaptation of the RITM-200 system originally developed to power modern nuclear icebreakers, such as the Arktika and Ural. These newer reactors are more compact and powerful than older Soviet designs, allowing for more efficient vessel operation.

By repurposing icebreaker technology for stationary offshore use, Russia aims to provide dependable, long-term power to remote industrial zones in the Arctic that lack access to traditional power grids or reliable renewable energy. This project follows the precedent set by the Akademik Lomonosov, which has supplied power to Chukotka since 2020. Rosatom intends to export these modular floating reactors to coastal and island markets globally.
