Russia launches world's first floating nuclear reactor in Arctic

\

• Russia’s floating nuclear power station Akademik Lomonosov expected to change the Arctic, warn environmentalists
• The reactor's trip is expected to last between four and six weeks, depending on the weather conditions and the amount of ice on the way

•  Russia will launch the world's first floating nuclear reactor and send it on an epic journey across the Arctic on Friday, despite environmentalists warning of serious risks to the region.
• Loaded with nuclear fuel, the Akademik Lomonosov will leave the Arctic port of Murmansk to begin its 5,000 kilometre voyage to northeastern Siberia.
  Nuclear agency Rosatom says the reactor is a simpler alternative to building a conventional plant on ground that is frozen all year round, and it intends to sell such reactors abroad.
  But environmental groups have long warned of the dangers of the project, dubbing it a potential "Chernobyl on ice" and a "nuclear Titanic."
  A deadly explosion this month at a military testing site in Russia's far north, causing a radioactive surge, has prompted further concerns.
