  • Japan: Nuclear fuel at Fukushima No. 1 unit melted after full exposure

    Nuclear fuel at Fukushima No. 1 unit melted after full exposure TOKYO (Kyodo) -- Water inside the troubled No. 1 reactor of the Fukushima Daiichi nuclear power plant was at an unexpectedly low level, not enough to cover the nuclear fuel, hinting that a large part of the fuel melted after being fully exposed, Tokyo Electric Power Co. said Thursday based on data obtained by adjusted gauges. But the plant operator said the water at the bottom of the reactor pressure vessel holding the fuel is keeping the melted fuel cool, assuring that the company is succeeding in preventing the...

    TEPCO finds another leak of radioactive water into sea Thursday 12th May, 03:31 AM JST TOKYO — Tokyo Electric Power Co said Wednesday it had detected another leak of highly contaminated radioactive water into the sea near the Fukushima Daiichi nuclear power plant but was able to stop the flow. Some radioactive substances also apparently passed through the ‘‘silt fence’’ curtain barriers installed in the sea near the crippled plant to prevent the spread of radioactive materials when leaks occur, raising concern that they may contaminate a wider area of the Pacific Ocean. The water leaked from a pit close...

    Restoration Under Way At Nuke Plant, Radiation Fear Spread To Tokyo TOKYO (Kyodo)--Work to restore power and key cooling functions was disrupted again Wednesday at the crisis-hit Fukushima Daiichi nuclear plant after smoke caused workers to evacuate, while fear of radioactive pollution spread to Tokyo with an alert not to give tap water to infants. The plant operator Tokyo Electric Power Co. (9501) said it learned at around 4:20 p.m. that black smoke was seen rising at the No. 3 reactor building, leading to evacuation of workers from the four troubled reactors, but added about an hour later that it...

    UPDATE AS OF 2 P.M. EDT, SATURDAY, MARCH 19: Radiation doses at the Fukushima Daiichi nuclear power plant continue to decrease. Radiation dose rates at the site boundary of the Fukushima Daiichi nuclear power plant ranged from 1 millirem to 3 millirem per hour on March 18. Eighteen locations were monitored in a 30-kilometer to 60-kilometer radius of the plant. The highest radiation dose rate at any of those locations was 14 millirem per hour. Tokyo Electric Power Co. (TEPCO) is installing high voltage cables from a nearby transmission line to reactors 1 and 2 at Fukushima Daiichi. Power is...

    UPDATE AS OF 10:00 A.M. EDT, SATURDAY, MARCH 19: At a March 19 news conference, Japan's Chief Cabinet Secretary Yukio Edano said that sea water injection is continuing at reactors 1, 2 and 3 at the Fukushima Daiichi nuclear power plant. Preparations were being made to spray water into the used fuel pool at reactor 4, and an unmanned vehicle sprayed more than 1,500 gallons of water over seven hours into the used fuel pool at reactor 3, Edano said. He also said he believed that the situation at the reactor 3 fuel pool is stabilizing. Some reactor cooling capacity...

    ASIA NEWSMARCH 19, 2011. Bid to 'Protect Assets' Slowed Reactor Fight By NORIHIKO SHIROUZU, PHRED DVORAK, YUKA HAYASHI and ANDREW MORSE TOKYO—Crucial efforts to tame Japan's crippled nuclear plant were delayed by concerns over damaging valuable power assets and by initial passivity on the part of the government, people familiar with the situation said, offering new insight into the management of the crisis. Meanwhile, a regulator who was inspecting the Fukushima Daiichi nuclear-power complex when the quake hit offered The Wall Street Journal one of the first eyewitness accounts of the havoc at the site, describing how the temblor took...

    TOKYO (MNI) - Tokyo Electric Power Co (TEPCO) has succeeded Saturday in restarting an emergency diesel generator and resuming the cooling functions in Reactors 4 and 5 in its Fukushima nuclear power facility as work continued to bring power to the other reactors. Reactors 4 and 5 at the plant are set away from the other four reactors, which sustained the most damage in the massive quake and tsunamis on March 11. Meanwhile, workers have succeeded in attaching a power cable to the crisis-hit Fukushima nuclear power plant and are now working inside to ensure success when they switch on...

    UPDATE AS OF 11:20 A.M. EDT, FRIDAY, MARCH 18: Reactors 1, 2 and 3 at the Fukushima Daiichi nuclear power plant are in stable condition, with workers continuing to provide seawater cooling into the reactors. Containment integrity is believed to be intact on reactors 1, 2 and 3, and containment building pressures are elevated but are within design limits. Site radiation doses have been decreasing since March 16. Radiation dose rates are fluctuating based on some of the relief operations, such as adding cooling water to the used fuel pools. Recent readings at the plant boundary are about 2 millirem...

U.S. officials said Thursday they were ramping up their ability to collect their own information about radiation levels and the condition of the stricken Fukushima Daiichi nuclear plant. The Energy Department has delivered to Japan...

Separately, workers have been scrambling to restore power at the plant by installing cables connected to Tohoku Electric Power Co.'s (9506) power grid. SDF helicopters dropped a total of about 30 tons of water in four trips on the Fukushima Daiichi power plant's No. 3...

    If there is one person outside Japan who knows what the crisis workers at the Fukushima nuclear plant are going through now it is 64-year-old Andriy Chudinov. One of the first Chornobyl trouble-shooters to get to the disaster site of the world’s worst nuclear accident in 1986 and a rarity in that he survived, Chudinov looks back on those traumatic events with calmness, sadness and resignation. He generously applauds the workers who are fighting to bring Japan’s quake-damaged nuclear reactors under control. “These are good guys. After all, they have had it even worse than we did. They had a...

    New Power Line Installed At Fukushima Daiichi Plant: Govt TOKYO (Nikkei)--Japanese officials have installed cables to supply electricity from Tohoku Electric Power Co.'s (9506) power grid to the Fukushima Daiichi nuclear power plant, a step they hope will help inject water more efficiently into the facility's crippled reactors that are at the center of Japan's nuclear crisis, the government's Nuclear and Industrial Safety Agency said at a news conference Thursday night. Officials will try to connect the cable to the plant's No. 2 reactor on Friday, the agency said. The No. 2 reactor's containment vessel was partly damaged in its...

    High temperatures inside the building that houses the plant's No. 4 reactor may have caused fuel rods sitting in a pool to ignite or explode, the plant's owner said. By Tuesday afternoon, Edano said radiation readings -- which had reached dangerously high levels at the plant earlier -- had decreased. "We have to monitor the situation closely, but the high concentration of radioactive material is not emitting constantly from the No. 4 reactor right now," he said. Edano said readings at the gate at 3:30 p.m. Tuesday (2:30 am. ET) were 596.4 microsieverts per hour -- compared to a high...
