Plant Status

  • 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.

Plant Status

  • Tokyo Electric Power Co. (TEPCO) is working to restart full-scale tests of the water filtration system it will use to decontaminate and recycle radioactive water that has flooded the basements of buildings at the Fukushima Daiichi nuclear energy facility. The system went into full operation on Friday but was shut down after five hours when radiation levels rose more quickly than anticipated in the part of the system that removes oil and sludge. TEPCO may add more equipment to remove oil or lower the water flow rate through the system. Cooling water injections into reactors 1, 2 and 3 are accumulating in the building basements at the rate of 500 tons per day, and could overflow in about a week if the decontamination system is not functional by then.

  • The Nuclear Regulatory Commission staff said it now appears the agency was mistaken in its early conclusion that the used fuel pool at the Fukushima Daiichi reactor 4 may have lost all cooling water. “According to the latest information, it is unlikely it ever went completely dry,” said William Borchardt, NRC executive director for operations, in a progress briefing Wednesday for the NRC commissioners. Concern about the potential for overheating in the pool was a factor in the NRC’s conservative call for U.S. citizens to evacuate as far as 50 miles from the plant, NRC Chairman Gregory Jaczko told a congressional committee yesterday. “We are continuing to review and re-evaluate the 50-mile recommendation,” he said.
