Tokyo Electric Power Co. has radioactive water problems at its crippled Fukushima No. 1 nuclear plant that seem uncontainable, as seen in the latest case to beset the utility: tanks used to store highly tainted water that was used to cool its melted reactors but now must be safely stored are leaking.
The plant, part of which was built on filled-in land, also faces the risk of liquefaction if another big temblor hits.
The tank leaks come as Tepco struggles to halt the flow, some 300 tons a day, of highly radioactive groundwater into the Pacific, where it is believed wreaking environmental havoc.
