![]() The cylindrical base is 1.2 meters thick with a diameter of about 6 meters. The plant ’s operator, Tokyo Electric Power Co., suspects the tremendous heat from the nuclear fuel may have melted the concrete of the base supporting the pressure vessel. 1 reactor caused most of the fuel to melt through the bottom of the pressure vessel. Officials believe the meltdown at the No. Photos taken by the remote-controlled robot showed not only the exposed metal framework but what looked like a pile of melted fuel on top of the framework. 1 reactor bore the brunt of the damage at the nuclear complex. The Fukushima plant went into triple meltdown after the magnitude-9.0 Great East Japan Earthquake in 2011 that generated devastating tsunami. 1 reactor found that a large portion of the concrete base supporting the pressure vessel appears to have melted, leaving only a metal framework holding up the pressure vessel.Įxperts are now saying the remaining structure may not be strong enough to withstand a big earthquake, a troubling prediction given that the region has been hit by a number of strong temblors in recent months.Īn official with the Agency for Natural Resources and Energy who is handling decommissioning work said at a May 26 news conference the remaining structure could not be described as safe, noting that a large portion of the concrete base only had the metal framework remaining.Īt a news conference the previous day, Toyoshi Fuketa, chairman of the Nuclear Regulation Authority, said, “We remain concerned about whether it will withstand a strong quake.” Photos taken by a remote-controlled robotic device sent into the No. 1 nuclear power plant may be too flimsy to withstand another major earthquake. Alarm bells are sounding over signs the heavily damaged structure of the Fukushima No.
