Japanese Minister Calls for Restart of Nuclear Plants to Ease Electricity Supply Shortages
Tokyo Electric Power Co. is continuing efforts to reduce the accumulation of radioactive water from cooling operations at Fukushima Daiichi reactors 1, 2 and 3. With reactor temperatures stabilizing, the company is reducing the water injection flow rate into the reactors. The total inflow rate is now about 386 tons per day. Heavy rains are challenging TEPCO’s effort to contain water accumulating onsite.
TEPCO’s system to decontaminate and recycle the radioactive water in the basements of reactor buildings is now operating. As of Friday, a total of 3,000 tons of water has been decontaminated. The system is now filtering water at a rate of 400 tons per day. The design capacity of the system is 1,200 tons per day. The desalination component of the system has also begun operating. TEPCO plans to recycle the decontaminated water to cool the reactors, possibly as soon as next week.
About 99 tons of water was injected late last week into the reactor 4 used fuel pool using the new temporary “giraffe” injection line. The equipment storage pool—referred to in the United States as the “dryer separator pit”—has also been refilled with water to shield workers from activated metals being stored there.
