The Nuclear Regulation Authority on Wednesday gave the green light to the restart of an aging nuclear power plant northeast of Tokyo, idled since it was hit by the tsunami that caused meltdowns at the Fukushima No. 1 plant.

The Tokai No. 2 plant is the first nuclear plant affected by the March 2011 earthquake and tsunami disaster to have cleared screening by the nuclear watchdog. Other steps are still required before it can resume operations.

Due to the quake, the plant in the Ibaraki Prefecture village of Tokai suffered an emergency automatic shutdown of its reactor and was cut off from its external power source.
