Japan’s nuclear reactor fleet generated 81 TWh of electric power in 2023, about 50% higher than the preceding year, the Japan Atomic Industry Forum (Jaif) said on Wednesday.

Jaif said the nuclear generation figure is the highest in recent years in a country which has been gradually restarting nuclear reactor units since a nationwide shutdown in the aftermath of Fukushima-Daichi nuclear accident in 2011.

In 2023, Japan’s total number of restarted reactors reached 12, representing a generating capacity of 11,608 MW.
