Tokyo Electric Power Co. has announced the official decision to decommission all of the four units at Fukushima Daini Nuclear Power Station.

TEPCO said it will take more than four decades to dismantle the four reactors at the Daini plant. The estimated cost for dismantling and decontamination will be $2.6 billion.

TEPCO had been considering this step since last year—in conjunction with the decommissioning of Fukushima Daiichi—in order to make the inhabitants of local communities feel safer. The decision was made following a thorough consideration of various issues affecting both Fukushima Daiichi and Daini, including the securing of the necessary human resources, the safe decommissioning of the two power stations and the impact on our business.

They emphasize the fact that they took into account the wishes of local residents for decommissioning of the entire plant and that they will continue to make sincere efforts to safeguard the wellbeing of everyone in the region with regard to both Fukushima Daini and Fukushima Daiichi. 

Going forward, TEPCO will explain to local communities how it plans to process the decommissioning work of Fukushima Daini in an easy-to-understand way, aiming to proceed with their full understanding. 

In April 2019, Japan partially lifted an evacuation order in Okuma, for the first time since the disaster, but many former residents are still reluctant to return. 

The other hometown, Futaba, remains off-limits, as are several other towns nearby. 

The decommissioning means Japan is left with 33 reactors to generate electricity nationwide, compared with 54 before the disaster.
