TOKYO: The estimated cost of cleaning up Japan’s wrecked Fukushima nuclear plant has doubled to nearly 22 trillion yen ($190 billion), with decommissioning expenses expected to continue to increase, a government panel said Friday. The estimate raises the decommissioning part of the total costs to 8 trillion yen ($70 billion) from the current 2 trillion ($17.5 billion) because of surging labor and construction expenses. Panel officials said the numbers could still grow as experts learn more about the damage to the plant’s reactors and determine fuel removal methods. Costs for compensation, decontamination of the area and waste storage have also grown significantly.
