Saint-Petersburg, 28 April 2018 – Akademik Lomonosov, the world’s, so far, only 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 would 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.
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 connecting 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 atomic 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 for 18th century Russian scientist Mikhail Lomonosov.
The lifecycle of the nuclear FPU is 40 years with the possibility of being extended by 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 additional to having a greater power capacity, OFPUs will be smaller than their predecessors.
Notes to the editor:
The FNPP was designed to made it possible to supply electricity to hard-to-reach areas of the Russian Federation, regardless of transport infrastructure, landscape, and cost of fuel delivery. Up to 40% of the cost of fossil fuel-based electricity generation is attributed to the price of coal, oil or gas, as well as to the cost of their delivery. This figure is even higher for especially remote locations. The small size, light weight, and fixed cost of the FNPP eliminate many such challenges. These small nuclear reactors can operate non-stop without the need for refuelling for three to five years, thereby considerably reducing the cost of electricity generation.
The reactors have the potential to work particularly well in regions with extended coastlines, power supply shortages, and limited access to electrical grids. The plant can be delivered to any point along a coast and connected to existing electrical grids.
ROSATOM is the only company in the world to offer integrated clean energy solutions across the nuclear supply chain and beyond, including the design, build and operation of nuclear power stations, uranium mining, conversion and enrichment, the supply of nuclear fuel, decommissioning, spent fuel storage and transportation and safe nuclear waste disposal. With seventy years’ continuous experience, the company is the world leader in high-performance solutions for all kinds of nuclear power plants. It is also working in the segments of wind generation, nuclear medicine, energy storage and other.
Headquartered in Moscow, the company brings together over 300 enterprises and organizations and over 250,000 employees based in 44 countries across the world. Globally, the company has the second biggest uranium reserves, has 40% of the world’s enrichment market, and is the world's biggest builder of the latest generation nuclear power stations and US$133 billion 10-years export order book.
