The Nuclear Regulation Authority formally decided Wednesday on the screening document certifying that the Nos. 3 and 4 reactors at Kyushu Electric Power Co.’s Genkai nuclear power plant in Saga Prefecture satisfied the country’s safety standards for their restart.

The latest decision made at an NRA regular meeting brings to 10 the number of reactors, at five nuclear power plants, that have satisfied the regulator’s new safety standards, introduced after the nuclear disaster at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear power plant in 2011. The two Genkai reactors are scheduled to be back online sometime in or after summer this year.

The Kyushu power company applied for a safety screening on those reactors in July 2013. At that time, the company anticipated an earthquake with an acceleration of up to 540 gal at the Genkai plant followed by tsunami of up to 3 meters high. However, the NRA deemed the simulation as “too optimistic” and the figures were raised to an acceleration of 620 gal with 4-meter-high tsunami.

In November last year, the NRA approved a draft document as the two reactors complied with the new standards. The NRA then solicited public opinions and received 4,200 comments, including concerns over possible earthquakes, but concluded that there was no problem with compliance.

With the formal decision being made on the Genkai plant, the focus for the restart has moved to an approval of a construction plan that maps out the specifications of related equipment for safe operation as well as whether it can obtain the consent of local governments for the restart.

So far, nuclear reactors that have passed the NRA’s screenings under the new standards are the Nos. 1 and 2 reactors at Kyushu’s Sendai power plant in Kagoshima Prefecture, the Nos. 1 to 4 reactors at Kansai Electric Power Co.’s Takahama plant and KEPCO’s No. 3 reactor at Mihama plant, both in Fukui Prefecture, and the No. 3 reactor at Shikoku Electric Power Co.’s Ikata plant in Ehime Prefecture. Currently, two reactors — Sendai plant’s No. 1 and Ikata’s No. 3 — are online.
