TOKYO (Sputnik) — Before the Fukushima accident in 2011, some 30 percent of Japan's energy needs were met by nuclear power. At the moment, the work of 45 out of 48 nuclear reactors in the country is still halted, with two plants previously restarted at Sendai in August and September, 2015.
The Takahama plant is the first of the fast-breeder type of reactors that operate on uranium-plutonium mixed oxide fuel to become restarted.
In March 2011, a 9.0-magnitude earthquake hit northeastern Japan. A 14-meter tsunami followed the tremors, flooding four out of the six reactors at the power plant Fukushima-1 and disabling their cooling systems. It became the largest nuclear-related accident in 25 years, since the Chernobyl disaster.
