Another Radioactive Water Leak Reported at Fukushima Plant

6 Apr
Tokyo Electric Power Co. said as much as 12 tons of radioactive water leaked from a pipe at its crippled Fukushima nuclear station, the second such incident in 11 days at the same pipeline, raising further doubts about the stability of the plant.

Part of the water may have poured into the sea through a drainage ditch, Osamu Yokokura, a spokesman for the utility, said by phone. The company known as Tepco stopped the leak from a pipe connecting a desalination unit and a tank today, he said.

“There will be similar leaks until Tepco improves equipment,” said Kazuhiko Kudo, a research professor of nuclear engineering at Kyushu University, who visited the plant twice last year as a member of a panel under the Nuclear and Industry Safety Agency. “The site had plastic pipes to transfer radioactive water, which Tepco officials said are durable and for industrial use, but it’s not something normally used at nuclear plants,” he said. “Tepco must replace it with metal equipment, such as steel.”

Tepco has about 100,000 tons of highly radioactive water accumulated in basements at the Fukushima Dai-Ichi nuclear station nearly 13 months after the March 11 quake and tsunami caused meltdowns and the worst radiation leaks since Chernobyl. The tsunami knocked out all power at the station, causing cooling systems for reactors to fail. The utility was forced to set up makeshift pumps to get cooling water to the reactors, with most of it then draining into basements. Continue reading
