Tokyo Electric Power Company says it has halted operation of a new wastewater treatment system at the damaged Fukushima Daiichi nuclear plant.
The system is designed to eliminate almost all radioactive substances from wastewater.
TEPCO says an alarm sounded to indicate abnormalities in its Advanced Liquid Processing System, or ALPS, shortly before 7AM on Friday. Workers at the utility are looking into the cause of the alarm.
The utility resumed its test-runs of the new system on Friday of last week following a month-and-a-half suspension. But it had to shut down the system less than 24 hours later due to technical problems, and resumed operations last Monday.
Suga: No leaks from ALPS at Fukushima Daiichi
Japan's top government spokesman says a new wastewater treatment system is being investigated at the damaged Fukushima Daiichi nuclear power plant following reports of abnormalities.
Yoshihide Suga told reporters on Friday morning that no abnormalities, including leaks of contaminated water, have yet been found.
Tokyo Electric Power Company halted test-runs of its Advanced Liquid Processing System, or ALPS, after an alarm sounded to indicate abnormalities earlier on Friday. The system is designed to eliminate almost all radioactive substances from wastewater.
Suga said he was told that the water treatment process was suspended after the alarm.
