Floating Nuclear Power Plants Are An Affordable And Clean Alternative To Fossil Fuels December 23, 2020 Share Danish startup Seaborg Technologies says it can make affordable nuclear electricity a viable alternative to fossil fuels. It says its floating barges fitted with advanced nuclear reactors could provide electricity across the developing world as soon as 2025. This news follows the success of the world’s first floating nuclear power plant (the Akademik Lomonosov) to go online in 40 years. It was built in a St Petersburg shipyard in Russia, then towed to and docked at Pevek, Chukotka, in the country’s remote Far East in December 2019.
