Japan Has Restarted Five Nuclear Power Reactors In 2018

With Shikoku Electric Power Company's 890 megawatt (MW) Ikata-3 reactor, Japan has restarted a total of five nuclear reactors in 2018. 'Japan had suspended its nuclear fleet in 2013 for mandatory safety checks and upgrades following the 2011 Fukushima accident, and before 2018 only four reactors had been restarted,' reports OilVoice. From the report: Following the Fukushima accident, as each Japanese nuclear reactor entered its scheduled maintenance and refueling outage, it was not returned to operation. Between September 2013 and August 2015, Japan's entire reactor fleet was suspended from operation, leaving the country with no nuclear generation. Sendai Units 1 and 2, in Japan's Kagoshima Prefecture, were the first reactors to be restarted in August and October 2015, respectively.

The restart of Japan's nuclear power plants requires the approval of both Japan's Nuclear Regulation Authority (NRA) and the central government, as well as consent from the governments of local prefectures. In July 2013, the NRA issued more stringent safety regulations to address issues dealing with tsunamis and seismic events, complete loss of station power, and emergency preparedness. As part of Japan's long-term energy policy, issued in April 2014, the central government called for the nuclear share of total electricity generation to reach 20%-22% by 2030, which would require 25 to 30 reactors to be in operation by then. In 2017, four operating nuclear reactors provided 3% of Japan's total electricity generation.
