TOKYO -- By pinning down the location of melted fuel at the Fukushima Daiichi nuclear power plant, Tokyo Electric Power Co. Holdings has made modest but valuable progress on the toughest part of the decommissioning process.
The biggest hurdle to clear before the teardown can begin is confirming where the fuel is and how much is there so it can be removed. Scanning by Tepco and the government found that the bulk of unit 2's fuel is likely at the bottom of the pressure vessel.
