Kyodo news: Tepco halts cleaning water after five hours


 Tokyo Electric Power Co. put off its plan to start using treated water Saturday to cool reactors at the Fukushima No. 1 nuclear plant, after suspending a key water treatment system less than five hours after full operation began.

 The treatment system, which began full operation at 8 p.m. Friday, was halted at 12:54 a.m. Saturday when the radiation level for a component to absorb cesium reached its limit of 4 millisieverts per hour and required replacement earlier than expected.
 The utility was initially planning to replace the cesium absorber once a month.
 The system is seen as a key step to containing the 3-month-old crisis. It is designed to clean highly radioactive water accumulating at the plant and preventing restoration work.
 "It is still uncertain when we can restart the water treatment system . . . but we will probably be able to solve the problem within a week, by the time the facility where the polluted water was transferred is full," Tepco spokesman Junichi Matsumoto said.
