Japan's Tohoku Elec restarts Onagawa reactor after 13-year hiatus

Tohoku Electric Power resumed operations on Tuesday of the 825 megawatt (MW) No. 2. reactor at its Onagawa nuclear reactor in northern Japan,. for the first time since the Fukushima nuclear disaster in 2011,. a company representative said.

The plant runs boiling water reactors (BWR), the same as. those in Fukushima, and was the closest nuclear station to the. epicentre of the magnitude 9 earthquake in 2011. It is eastern. Japan's first nuclear power reactor to restart since then.

The long-delayed reboot takes the variety of Japan's. operational reactors to 13, with an integrated capacity of 12,433. MW.

As Chugoku Electric Power prepares to reboot the. 820-MW No. 2 reactor at its Shimane nuclear power station in. western Japan later on this year, the country's demand for. liquefied natural gas (LNG) is anticipated to fall next year.

Increased operation of nuclear power plants should also assist. Japan to fill growing power demand from semiconductor plants and. data centres supporting applications in artificial intelligence. ( AI).

The federal government expects power output to grow to 1.35 trillion. to 1.5 trillion kilowatt-hours (kWh) by 2050, up from 1 trillion. kWh predicted for the existing years as Japan sets up more information. centres, chip factories and other energy-consuming services.

For Tohoku Electric, the Onagawa reboot follows an overall. investment of 570 billion yen ($ 3.72 billion) on precaution. to fulfill harder guidelines embraced after the Fukushima disaster.

The restart is expected to increase the firm's profit by 13. billion yen for the fiscal year ending next March, as lower. fuel costs due to less costs on fossil fuels will balance out. increased devaluation and amortisation costs connected to the. Onagawa plant, its representative said.
