QHow long will it take to decommission Fukushima Daiichi Nuclear Power Plant?
ADecommissioning work is likely to take around 30–40 years.

Decommissioning work is being carried out with the utmost priority on safety, and it is expected to take around 30–40 years to completely decommission the power plant.

The work is difficult to predict because there are no direct precedents, but a large team is working closely together and communicating objectives to complete the decommissioning process. The central government will continue to be responsible for the decommissioning of the plant and the management of contaminated water, with a view to have work complete within 30–40 years.
