Fukushima plant decontamination water stopped five hours after its commissioning

The plant decontamination of radioactive water built at the Fukushima nuclear power plant  was arrested five hours after its inception, because of excessive levels of radiation, said the Saturday, June 18 operator of the plant. Parts of the system that absorb radioactive cesium must be changed much sooner than expected because of excessive levels of radiation, officials said Tokyo Electric Power (TEPCO).

The operator did not say when the plant contamination would begin to operate. According to the Japanese company, radioactive sludge in the system for reprocessing or treated water are more radioactive than Tepco imagined at the outset.

Some 100,000 tons of highly radioactive water accumulated in the reactor building and turbine of the plant since the earthquake and tsunami of March 11. These effluents prevent workers from entering the facility to re-cooling systems of nuclear fuel. The decontamination facility should normally be capable of processing 50 tons of waste per hour, or 1200 tons per day by dividing the radioactivity by a factor of 1000 to 10 000 times.
