“A nuclear expert has told the BBC that he believes the current water leaks at Fukushima are much worse than the authorities have stated.
Mycle Schneider is an independent consultant who has previously advised the French and German governments.
He says water is leaking out all over the site and there are no accurate figures for radiation levels.
Meanwhile the chairman of Japan’s nuclear authority said that he feared there would be further leaks.
The ongoing problems at the Fukushima plant increased in recent days when the Tokyo Electric Power Company (Tepco) admitted that around 300 tonnes of highly radioactive water had leaked from a storage tank on the site. … ”
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.
And the groundwater problem will probably dog Tepco over the next four decades or so as it tries to scrap and entomb the spent fuel from reactors 1 to 4 and the melted fuel inside units 1 to 3.
A key to minimizing the exposure of groundwater to the highly radioactive coolant water leaking into the basements of the buildings housing the crippled reactors is to learn the courses the groundwater takes from the landward mountains to the sea under the plant, experts say. … ”
