Asahi Shimbun, June 11, 2013: The workers have yet to gain a grasp of the locations and condition of the fuel debris. They have yet to develop extraction equipment and determine removal methods.
Mainichi, June 11, 2013: Uncertainty over the location of melted fuel inside the crisis-hit Fukushima No. 1 Nuclear Power Plant continues to cast a shadow over plans to remove the fuel at an early date [...] Reactor Nos. 1-3 at the plant contained a total of 1,496 rods of nuclear fuel in their cores. [...] Each fuel rod weighs about 300 kilograms, and a high level of technical expertise would be required when undertaking a remote control operation to cut up and retrieve clumps of scattered radioactive materials weighing a combined 450 tons or thereabouts. [...] the cores of reactors at the Fukushima plant have holes, and the task at hand is finding which parts have been damaged [...] In a news conference on June 10, a representative of the Ministry of Economy, Trade and Industry’s Agency for Natural Resources and Energy said that bringing forward the plans would be dependent on developing technology, and suggested that the plans might even end up being delayed.
