Fukushima Pref. to decommission all 10 local nuke reactorsThe Fukushima Prefectural Government has decided to decommission all 10 reactors in its jurisdiction, including those at the Fukushima No. 2 nuclear plant, in conjunction with its disaster recovery project, it has been learned.
A vision for restoration created by the prefectural government in August promoted the formation of a "society not relying on nuclear power," but made no actual reference to decommissioning reactors. Fukushima Gov. Yuhei Sato was expected to formally announce the measure in a news conference on Nov. 30.
Earlier, Sato stated that the No. 1 to 4 reactors at the damaged Fukushima No. 1 nuclear complex would be decommissioned, but when it came to the plant's No. 5 and No. 6 reactors and those at the Fukushima No. 2 plant, he had simply stated, "It is inconceivable to restart them."
..."The principle of moving away from nuclear power, which was put forward in our vision for restoration, has not changed," he said. "In the future we will have a Fukushima Prefecture without nuclear power."

According to Tokyo Electric Power Co.'s analysis, all of the fuel inside the No. 1 reactor melted after cooling functions failed in the wake of the March 11 earthquake and tsunami, with a substantial amount of the fuel melting through the base of the reactor pressure vessel and dropping into the outer primary container.
If the erosion had expanded another 37 cm, the damage would have reached the steel wall, according to the utility known as TEPCO.
...Currently, the melted fuel inside the Nos. 1 to 3 reactors is believed to be cooled by water injection and no further erosion is occurring, it said.
