Japan’s Prime Minister Fumio Kishida has called for up to nine nuclear plants to be put into operation to mitigate tight supplies expected this winter. The country could meanwhile resume operation of more than 10 thermal power plants to ensure electricity security this summer, he said.
Kishida’s comments at a press conference on July 14 come as the nation grapples with a summer power crunch. Earlier this summer, the Japanese government issued an “electricity shortage alert” for the first time under a new system as parts of the nation, including Tokyo, Saitama, Tochigi, and Ibaraki prefectures, suffered record-high heat.
Security of country’s power supplies has been compounded by the slow startup of its nuclear power plants, which were shut down after the March 2011 Fukushima disaster, as well as retirements of aging thermal plants for environmental reasons. So far, only 10 of Japan’s 33 reactors are operating. Another seven have been cleared by the nation’s nuclear regulator.
The country is meanwhile suffering a surge in fuel prices, which stems from tight markets in the wake of Russia’s invasion of Ukraine.…
Kansai Electric Power Co. (KEPCO) announced it will permanently close two older nuclear reactors in Japan, rather than invest nearly 100 billion yen ($ 900 million) to bring the units up to the country’s new safety regulations. Japan’s Nuclear Regulation Authority (NRA) created new standards for the country’s nuclear plants after the meltdown at the Fukushima Daiichi plant in March 2011.
KEPCO on December 22 said it will decommission reactors No. 1 and No. 2 at the Oi facility in central Japan over the next year. Each unit has a generation capacity of 1,175 MW. The reactors, which came online in March 1979 and December 1979 respectively, will be the largest decommissioned in the country since the Fukushima disaster, which occurred when a 9.0-magnitude earthquake caused a massive tsunami that flooded the Fukushima plant in the northeastern part of the country. The resulting release of radiation was the largest since the Chernobyl meltdown in Russia in 1986.

Japan’s nuclear watchdog agency has given Tokyo Electric Power Co. (TEPCO) conditional approval to restart two reactors at its Kashiwazaki-Kariwa plant. The units were taken offline after the Fukushima Daiichi meltdown in March 2011.
The country’s Nuclear Regulation Authority (NRA) on September 13 said TEPCO could restart the units after it provides a detailed plan of how it can ensure the operational safety of the boiling-water reactors, the same type that operated at Fukushima, which was crippled after an earthquake and tsunami struck the region, resulting in flooding at the nuclear plant. The Asahi Shimbun newspaper reported the NRA’s action.
A district court in March of this year ruled that TEPCO and the Japanese government were aware of risks at Fukushima and could have taken action to avoid the meltdown of three reactors.

Units 6 and 7 at the Kashiwazaki-Kariwa plant in Niigata Prefecture were among 54 nuclear facilities in Japan—the country’s entire nuclear fleet—ordered to shut down after the 2011 earthquake.…
Six years after the Fukushima disaster prompted an electricity crisis in Japan and sent tremors throughout the world’s nuclear power sector, Japan is determined to continue its reliance on nuclear for nearly a fifth of its power needs in the long term.
Nuclear will make up 20% to 22% of Japan’s power mix by 2030, under a long-term plan issued in 2015, Hirohide Hirai, the director general of Japan’s Ministry of Economy, Trade, and Industry (METI), told attendees at CERAweek by IHS Markit, which is taking place in Houston this week.
On March 11, 2011, nearly a day after the 3-minute, 9.0-magnitude Great Tohoku Earthquake struck northeastern Japan—and unleashed a tsunami that killed 20,000 people—the world learned that Tokyo Electric Power Co.’s (TEPCO’s) Fukushima Daiichi and Daini nuclear plants were in peril after rising waters inundated and disabled offsite power supplies.
All of Japan’s nuclear power plants were shut down for safety checks after the disaster. Six years later, only three of 45 operable reactors have come online: Kyushu Electric’s Sendai 1 and 2 (restarted in 2015), and Shikoku Electric Power Co.’s…
