On April 28, the world’s first floating nuclear unit, named FPU Academik Lomonosov, left Baltic Shipyard, JSC (Baltiyskiy Zavod) in St. Petersburg, where it has been building since 2009, to be towed to what will be its base in Chukotka, east of Russia.
The FPU ( floating power unit ) will be towed first from St. Petersburg to Murmansk, and then from Murmansk to Pevek, east of Russia. The FPU will be towed without nuclear fuel on board from Baltic Shipyard to the FSUE Atomflot headquarters in Murmansk.
FSUE Atomflot is part of the Rosatom group. Rosatom encompasses companies that come from all stages of the technological chain, from the extraction and enrichment of uranium, manufacture of nuclear fuel, manufacture and engineering of equipment, the operation of nuclear plants, etc.
This FPU unit has been designed as a constituent part of the floating nuclear plant (FNPP). Its main mission is to supply electricity and heating to remote places. The construction project of the FNPP plant will allow energy supply to regions such as Chukotka, and thanks to the implementation of this project the region will be able to have a powerful economic and social development.
In the second phase of the journey, already in the summer of 2019, will be transferred from Murmansk to the port of Pevek, loaded with nuclear fuel and with the crew on board.
The Federal Agency for Maritime and River Transport of Russia Marine Rescue Service of Rosmorrechflo will be responsible for carrying out the services related to towing and maneuver during the St. Petersburg-Murmansk-Pevek route. The average speed calculated for transport will be 3.5-4.5 knots under favourable conditions.
All the construction work necessary to create the ground infrastructure is being carried out in Pevek. The Quay, the hydraulic structure and other crucial constructions for the anchoring of the FPU and operation of the FNPP ( Floating Nuclear Thermal Power Plant ) will be ready to operate when the Academic Lomonosov FPU arrives.
The nuclear fuel will be loaded into the reactor and will be launched in Murmansk next autumn. At the same time, the FPU will be transported through the North Sea route to the operation location, unloaded at the dock and connected to Pevek’s coastal infrastructure.
After putting the FNPP into operation, by 2019, it will replace the Bilibino and Chaunskaya TPP nuclear power plants, which are technologically outdated. It will become the nuclear power plant located farther north around the world.
It has been designed to work as part of the aforementioned floating nuclear power plant FNPP and is a new kind of energy source based on Russian shipbuilding technology.
The plant has two KLT-40S reactors that can generate up to 70 MW of electrical power and 50 Gcal / h of heat during normal operation. This is enough to maintain activity in the city, with a population of 100,000 people. The unit is unique and is the first mobile unit in the world of low power. It is designed to operate in extreme areas of the north, and in the east of Russia. Its main task is to supply electric power to remote industrial power plants, ports and oil & gas platforms.
Rosatom says that its design has been oversized to ensure it can face any possible risk, having a large safety margin that exceeds all possible scenarios and makes these nuclear reactors invincible to tsunamis or other natural disasters.It also satisfies all the requirements established by the International Atomic Energy Agency ( IAEA) and does not pose any danger to the environment.
The Academik Lomonosov FPU has a length of 140 m, sleeve of 30 m, draft of 5.56 m, and displacement of 21,500 t.On board will take a crew of 69 people. The unit can easily be converted into a desalination plant producing up to 240,000 m3 of fresh water per day.
The service life of the plant is from 35 to 40 years, and refuelling of nuclear fuel will be done every 2.5-3 years.
The shipyard Baltic Shipyard specializes in the construction of surface ships, nuclear and electric diesel-powered icebreakers, nuclear-floating units, and floating distillation plants.
