Plant Status

  • Tokyo Electric Power Co. (TEPCO) has repaired faulty hoses and restarted the new cooling system for the reactors at the Fukushima Daiichi nuclear energy facility. The system resumed operations after the repair. The system, which on June 27 began circulating decontaminated water through reactors 1, 2 and 3, had developed leaks in pipes and hoses shortly after it was activated. Read More »

Plant Status

  • Tokyo Electric Power Co. (TEPCO) has partially restored a cooling water recycling system at the Fukushima Daiichi nuclear energy facility. Of the 16 tons of water injected per hour to cool reactors 1, 2 and 3, 13 tons are decontaminated water that has been processed through this system. In its first two weeks of operation, the water treatment system has processed about 1,850 tons of radioactive water that had accumulated at the plant. TEPCO suspended operations a number of times during test runs because of problems with a device that removes radioactive substances and subsequently switched to a different material that absorbs radiation. Goshi Hosono, an adviser to Japanese Prime Minister Kan, said that although the cooling system has not been fully restored from a pump failure last Saturday, the start of recycling cooling water is an important step toward stabilizing the reactors.

WASHINGTON, D.C.—Eighty percent of residents living near nuclear energy facilities favor the use of nuclear energy as one way to provide electricity in the United States. Half of them “strongly favored” the use of nuclear energy, compared to 11 percent who were “strongly opposed.”

Americans believe that companies that operate nuclear energy facilities are taking appropriate safety measures and are prepared for the most severe events that could impact U.S. reactors.

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.
