Kyushu Electric Power’s second 890MW reactor is operational at the Sendai nuclear power station in Kagoshima Prefecture, Japan.
The operator restarted their first reactor at the facility in August, which has the capacity to generate 890MW energy.
The facility was closed following the Fukushima disaster.
The 2011 meltdown at the Fukushima Daiichi power plant prompted Japan to shut down all of its 48 nuclear power facilities.
The restarting of the reactor at the facility has been carried out after thorough reviews, equipment checks and approval by Japan’s nuclear regulator.
The country has been overburdened with import costs, since it had to rely on fossil fuels after the nuclear restrictions were imposed, which also drove up the carbon emissions of the country.
Prime Minister Shinzo Abe is in support of nuclear restarts in the country, which intends to derive 20-22% of its total power mix from nuclear energy by 2030, despite opposition from environmental groups.
Kyushu Electric Power intends to start power generation of the second reactor on 21 October.
Commercial operations for the reactor have been scheduled to start from around mid-November.
Kyushu Electric Power president Michiaki Uriu said: "We will continue to make sincerely an all-out effort to deal with the Nuclear Regulation Authority’s inspections, and carry out carefully remaining process, putting utmost priority to safety, with a sense of alertness more than ever.
"To be worthy of peace of mind of all our stakeholder, we will promote initiatives for improving the safety and security of nuclear power with voluntary and ongoing measures, and make an effort of positive disclosure and communication activities."
