On 28 October 2011, the Japanese Atomic Energy Commission presented a timetable in a draft report, titled "“how to scrap the Fukushima reactors”". Within 10 years, a start should be made with the retrieval of the melted fuel within the reactors. First, the containment vessels of reactors 1, 2 and 3 should be repaired, then all should be filled with water to prevent radiation releases. Decommissioning would take more than 30 years, because the pressure vessels of the reactor vessels are damaged also. After the accident at Three Mile Island in 1979, some 70 percent of the fuel rods had melted. There, the retrieval of the fuel was started in 1985, and completed in 1990. The work at Fukushima was expected to take significantly longer because of the far greater damage and the fact that 4 reactors would need to be decommissioned all at the same time.
