Though Russia is one of the world’s largest producers of oil and gas, it is embarking on an ambitious and somewhat imaginative programme of building floating nuclear power stations, writes Tony Roulstone, Lecturer in Nuclear Energy at the University of Cambridge, online at 'The Conversation'. These reactors, mounted on huge, 140m by 30m barges, are being built in the Baltic shipyard in St Petersburg and will be floated through the Norwegian and Barents Seas to where they will generate heat and electrical power in the Arctic.
