Kansai Electric Power Co. is making arrangements to conduct special checks that wold enable two reactors at its Takahama nuclear plant in Fukui Prefecture to operate beyond the operational limit of 40 years, sources said.

Under tighter safety standards adopted after the 2011 start of the nuclear disaster at Tepco's Fukushima No. 1 plant, the operating life of reactors was limited to 40 years in principle. Special checks are needed in order for reactors to operate beyond 40 years.

If Kepco decides to conduct special checks on reactors 1 and 2 at the Takahama plant, it would be the first utility in the country to do so.
