The treatment system is designed to remove highly radioactive materials from the massive amounts of water accumulating at the plant, thus its full operation is vital for efforts to contain the three-month-old nuclear crisis, because Tepco hopes to eventually recycle the water to cool the plant's damaged reactors.
But the new system was halted at 12:54 a.m. Saturday, after becoming fully operational at 8 p.m. Friday, because the radiation level of a component to absorb cesium had reached its limit and required replacement much earlier than expected, Tepco officials said.
Tepco has been trying to ascertain why the component didn't work as hoped and is probing ways to solve the problem, company officials said.
