Russia launches floating nuke reactor despite warnings

           MOSCOW ? Russia has launched the worlds first floating nuclear reactor and sent it on an epic journey across the Arctic this week, despite environmentalists warning of serious risks to the region. Loaded with nuclear fuel, the Akademik Lomonosov left the Arctic port of Murmansk yesterday to begin its 5,000km voyage to northeastern Siberia. Nuclear agency Rosatom said the reactor is a simpler alternative to building a conventional plant on ground that is frozen all year round, and it plans to sell such reactors abroad. But environmental groups have warned of the dangers of the project, dubbing it a potential "Chernobyl on ice" and "nuclear Titanic". A deadly explosion this month at a military testing site in Russias far north, causing a radioactive surge, has prompted further concerns. The reactors trip is expected to last between four and six weeks, depending on the weather conditions and the amount of ice on the way. Work began on the 144m-long Akademik Lomonosov vessel in Saint Petersburg in 2006. When it arrives in Pevek, a town of 5,000 in the Siberian region of Chukotka, it will replace a local nuclear plant and a closed coal plant. It is due to go into operation by the end of the year, mainly serving the regions oil platforms as Russia develops the exploitation of hydrocarbons in the Arctic. Mr Rashid Alimov, head of the energy sector of Greenpeace Russia, said environmental groups had been critical of the idea of a floating reactor since the 1990s. "Any nuclear power plant produces radioactive waste and can have an accident, but Akademik Lomonosov is additionally vulnerable to storms," he said.

The Akademik Lomonosov, the world’s first floating nuclear power plant, leaving Saint Petersburg under tow.

As Rosatom plans to store spent fuel on board, Mr Alimov said "any accident involving this fuel might have a serious impact on the fragile environment of the Arctic". He added that there is "no infrastructure for a nuclear clean-up" in the region. Global warming and melting ice have made the North-east Passage - which connects the Atlantic Ocean to the Pacific along Russias northern coast - more accessible. When Agence France-Presse visited the vessel in May last year, it was a shabby brown colour. It has since been repainted in the red, white and blue of the Russian flag. It weighs 21,000 tons and has two reactors with a capacity of 35MW each, close to that of those used by nuclear icebreakers. It has a crew of 69 and travels at a speed of 3.5 to 4.5 knots. Mr Alimov said the project was a missed opportunity as Chukotka, a region larger than Texas and populated by only 50,000 people, has huge potential for the development of wind energy. "A floating nuclear power plant is a too risky and too expensive way of producing electricity," he said. The nuclear industry, seeking to reinvent itself in a gloomy market, is developing smaller, cheaper reactors to attract new customers. They follow the examples of submarines, icebreakers and aircraft carriers, which have long used nuclear power, and are intended for isolated areas with little infrastructure.
