Decontamination system down again at Fukushima

TOKYO -- The operator of Japan's crippled Fukushima nuclear plant said Tuesday it had shut down a key decontamination system used to clean radiation-tainted water, just hours after it came back online.
Tokyo Electric Power (TEPCO) switched off its Advanced Liquid Processing System (ALPS) after workers discovered leaks "seeping" from a tank late Monday.
About 8 liters (2.1 gallons) of tainted water is believed to have leaked out, a company spokesman said. He added there was no immediate safety risk as the water had been recovered.
The suspension came just six hours after the embattled operator switched back on two of three lines in the system, which cleans radiation-tainted water used to cool the reactors damaged by Japan's devastating 2011 quake-tsunami disaster.
The whole system had been shut down last Wednesday after TEPCO discovered a defect. The firm has repeatedly switched the system off over a series of glitches since trial operations began a year ago.
