Kyushu Electric Power Co. said Monday it will restart the No. 1 reactor at its Sendai nuclear plant on Tuesday, marking the country's first long-term return to nuclear power since the Fukushima crisis.

The reactor, in Satsumasendai, Kagoshima Prefecture, will be the first to go live under new safety standards that were put in place in 2013. The standards were drawn up after the meltdowns at the Fukushima No. 1 power plant in March 2011.

The restart, strongly pushed by the pro-business administration of Prime Minister Shinzo Abe, will deal a tough blow to anti-nuclear activists and citizens who have been calling for abolition of all nuclear power plants.
