The restart of units 3 and 4 at Kyushu Electirc Power Company's Genkai nuclear generating station is being postponed from this coming fall to later in the winter, possibly until early 2018, the company said.
The two reactors were given permission to restart by the Nuclear Regulation Authority after passing a series of safety tests in January, according to news service Nikkei Asian Review. But a second series of screening processes has been slower than expected. Among the new round of screening are steps to test the plant's pipes on their ability to withstand various levels of seismic activity.
Restarting the reactors, Kyushu estimates, could save the company $81.4 million per month in fuel costs
