The Japanese government says it will seek to phase out all nuclear power plants by 2040, although officials suggested that the target remains flexible. The new energy strategy, which places a 40-year lifespan on nuclear reactors and limits construction of new plants, would continue a national shift away from nuclear power following last year’s disaster at the Fukushima nuclear power station. Earlier this year Japan suspended operations at the last of its 50 nuclear power stations over public safety concerns. Most of the plants remain off-line. In announcing the new plan, Motohisa Furukawa, Japan’s minister of state for national policy, left open the possibility that five reactors that will be younger than 40 at the end of the 2030s will be allowed to remain in operation. In addition, Furukawa indicated that the central government would ultimately bow to a newly formed nuclear panel over such policy questions, the New York Times reported. Nuclear power provided nearly 30 percent of the nation’s electricity before the 2011 disaster, and many have questioned whether the country can meet its power needs without a nuclear sector.
