– TEPCO halts water circulation due to leaks (NHK, June 27, 2011):
The operator of the Fukushima Daiichi nuclear power plant has suspended using decontaminated water as a coolant because of leaky pipes.
Tokyo Electric Power Company began circulating recycled water through the No.1, 2 and 3 reactors at 4:20 PM on Monday.
But it halted the operation one and a half hours later after discovering water leaking from the pipes.
TEPCO has been attempting to run the decontamination system since June 14th. It has so far treated about 1,850 tons of the water.
The operator hopes to reduce the levels of radioactive wastewater accumulated at the plant as a result of injecting fresh water into the damaged reactors.
Circulating the decontaminated water around the reactors is considered an important step to stabilize them by mid-July as planned. It will also help prevent the volume of wastewater from increasing.
TEPCO says it will repair the leaks and hopes to resume water circulation soon.
