Akademik Lomonosov, the unique nuclear floating power unit (FPU), has set sail from the Baltic Shipyard. The unit is en route to its final destination – Pevek, Chukotka (in Russia's Far East), where it will operate as a floating nuclear power plant.

Akademik Lomonosov will first be towed to Murmansk, where nuclear fuel will be loaded into its reactors. First criticality of the reactors is scheduled for autumn 2018.

Vitaly Trutnev, director of Directorate for the Construction and Operation of Floating Nuclear Thermal Power Plants, a Rosatom's subsidiary, said:

"It is a significant milestone for our project as well as for the whole world's nuclear industry. Floating nuclear power plants will enable electricity and heat supply to the most remote regions boosting growth and sustainable development.

Building upon three hundreds of reactor-years of safe operation of units powering icebreakers, FNPP features the most cutting edge safety and security systems and is expected to be one of the safest nuclear installations in the world".

All necessary construction work to create on-shore infrastructure has already been completed in Pevek. The pier, hydraulic engineering structures, and other buildings, crucial for the mooring of FPU and operation of a FNPP, are tested and ready to use.

The process of developing involved a resolution of various complicated issues related to the deployment and operation of the floating power unit (FPU), including finding measures to prevent exposure of FPUs to significant seismic loads, residual tsunami waves and significant ice load. This technology is not only considered as an environmentally-friendly, but also is designed in accordance with stringent safety requirements.

In summer 2019, once nuclear fuel has been loaded and the crew has come aboard, nuclear FPU Akademik Lomonosov is expected be towed to the sea port of Pevek. Average towing speed is estimated at 3.5-4.5 knots. FNPP Akademik Lomonosov will replace Pevek's aging Bilibino Nuclear Power Plant and Chaunsk coal-fired power plant, saving about 50,000 tones of CO2 emissions per year compared to the current levels. Upon its connection to the grid, Akademik Lomonosov will become the northernmost nuclear installation in the world.

The nuclear FPU is equipped with two KLT-40C reactor systems (each with a capacity of 35 MW) similar to those used on icebreakers. Designed by Russian nuclear scientists and naval architects, the vessel is 144 metres long and 30 metres wide, and has a displacement of 21,000 tonnes. Akademik Lomonosov – the first ship of this kind – was named after the 18th century Russian scientist Mikhail Lomonosov.

The lifecycle of the nuclear FPU is 40 years with the possibility of being extended to up to 50 years. After decommissioning, the FPU will be towed to a special deconstruction and recycling facility.

Rosatom is already working on second generation FPUs, or Optimized Floating Power Units (OFPUs), which will be equipped with two RITM-200M reactors (each with a capacity of 50 MW). In addition to having a greater power capacity, OFPUs will be smaller than their predecessors.
