Kyushu Electric Power Co. is still preparing documents needed for two reactors at its Sendai nuclear power station in Kagoshima Prefecture to pass regulatory examinations that will enable their restart, over four months after they were given the green light, officials said Thursday.
The documents will be submitted later this month for reactor 1 and in March for reactor 2, Managing Executive Officer Akira Nakamura said at a Nuclear Regulation Authority meeting.
The two reactors at the power station are likely to be the first to be restarted. Currently, all reactors in Japan remain offline due to safety concerns that arose after the triple reactor meltdowns at Tokyo Electric Power Co.’s Fukushima No. 1 nuclear power station.
“We are doing final checks to the information given, including earthquake resistance,” Nakamura said at the NRA meeting. “We need more time.”
The NRA confirmed in September that the two Sendai plant reactors’ basic designs and safety measures satisfy new regulatory standards introduced in July 2013, effectively approving their restart.
The authority is examining regulatory approval documents on reactor design specifications and safety procedures in preparation for severe disasters.
Kyushu Electric applied to revise the documents by October last year, but it turned out that further amendments were necessary.
In November, the company said it would submit a final revised version by the end of 2014. But related work has progressed at a slower pace than expected, officials said.
Reactors 1 and 2 will clear regulatory procedures as soon as the NRA approves the revised documents. The reactors will come into operation after on-site inspections by NRA members.
Kyushu Electric hopes to restart reactor 1 ahead of reactor 2. The upcoming inspections will first deal with reactor 1.
