Two Tokyo Electric reactors at the massive Kashiwazaki-Kariwa power station in Niigata Prefecture are expected to clear the initial safety hurdle for restarts soon, sources said Friday.

According to the sources, the Nuclear Regulation Authority will start talks on the issue on Wednesday, with a view to compiling a document that will certify the two units passed the new safety requirements introduced after the Fukushima nuclear crisis.

Tokyo Electric Power Company Holdings Inc. has been struggling to recover ever since the triple core meltdown in March 2011 because the seven-reactor Niigata plant is a crucial money maker. The utility has spent years trying to restart the plant, which is the only nuclear complex it runs aside from the disaster-hit Fukushima No. 1 plant in Fukushima Prefecture.
