Lawsuit claims Tepco misled scale of 2011 Fukushima disaster, causing relief workers to be exposed to radiation.
Tokyo Electric Power Co.
Tokyo Electric Power Co. (TEPCO) announced that while transferring contaminated water containing radioactive material from leaking underground storage tank No. 3 to tank No. 6 at the Fukushima Daiichi Nuclear Power Plant on April 11 this year, water was discovered leaking from a joint connecting the piping being used for the transfer.
About 22 liters of water containing 6.4 billion becquerels of radioactive material leaked from the joint before the problem was chanced upon. TEPCO said the water leaked on top of the berm covering the storage tank and that there was no possibility of it seeping into the soil surrounding it.
