FLASH BACK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! AP: Experts warn about ground sinking at Fukushima plant — Tepco Adviser: Reactor building structures likely degraded; “Containment degradation” concerns back in 2011 Published: December 3rd, 2013 at 4:22 pm ET By ENENews Email Article Email Article 104 comments Associated Press, Dec. 3, 2013: A government panel proposed additional measures to lessen the radioactive water crisis at Japan’s crippled nuclear power plant, saying Tuesday that current plans are not enough to prevent the risk of a disaster. [...] A draft report, made available to reporters after the panel’s experts and officials met, proposes covering the ground with asphalt to reduce rain inflow [...] Radioactive water has been leaking from the damaged reactors and mixing with groundwater [...] Experts say that the underground water that flows into the reactor and turbine basements is mostly rainwater, which can be reduced by covering most exposed dirt with asphalt [...] Experts also cautioned that decreasing the amount of groundwater could cause the ground to sink in some areas with soft structure. Such vulnerable locations include the area where hundreds of tanks have been built to contain highly radioactive water, said Hitoshi Tsukamoto, a geologist at the National Institute of Advanced Industrial Science and Technology.
