  • Fukushima melt-down worse than Chernobyl

    Certainly, in the first hours after the tragedy happened the operators were too shocked to unveil any details to the public. However, things did not get clearer with time. Deputy Director at the Russian Institute for Nuclear Engineering, Chernobyl clean-up worker Igor Ostretsov commented on the situation in an interview with the VOR…

    "The Fukushima disaster has proved that nuclear industry should be controlled only by the state and not by private companies. The outcome of this tragedy has turned even worse than it was in Chernobyl. Graphite which was part of the reactor`s core, burnt out and vanished in the atmosphere. But at Fukushima the reactor`s core melted."

  • Exposure of Tepco pair exceeds limit

    Cumulative dose of workers over new crisis cap of 250 millisieverts

    Two Tokyo Electric Power Co. employees working at the stricken Fukushima No. 1 nuclear plant may have been exposed beyond the 250-millisievert limit set for the crisis, Tepco and the government said Monday.

    Tepco said it plans to check some 150 other workers who were engaged in similar work.


  • Pump failure nearly brings No. 5 to a boil

    The seawater pump in the cooling system for the Fukushima power plant's No. 5 reactor broke down Saturday evening, prompting repair crews to install a backup pump 15 hours later on Sunday afternoon, Tokyo Electric Power Co. said.

    Tepco discovered the pump had stopped at 9 p.m. Saturday but didn't announce it to the public until Sunday morning.

    The beleaguered utility said it notified the local and central governments of the situation on Saturday evening.

    The seawater pump was set up after the reactor's original pumps were knocked out by the March 11 earthquake and tsunami. It was part of the critical Residual Heat Removal System that was later used to safely ease the reactor into a cold shutdown on March 20.

  • Work suspended at Fukushima plant due to hard rain

    The operator of the Fukushima Daiichi nuclear plant has suspended some of its outdoor work due to heavy rain and strong winds caused by a tropical storm.

    Tokyo Electric Power Company says it is watching closely to ensure that contaminated water in reactor buildings and elsewhere do not flow outside as the water levels have been rising because of the rain.

    It has been raining since Sunday in the areas around the Fukushima plant.

  • Cooling system restored at No.5 reactor

    A broken pump has been replaced at the Number 5 reactor of the Fukushima Daiichi nuclear plant, and the temperature inside the reactor has started to decline.

    The reactor has been in a state of cold shutdown.

    State of cold shutdown means it has not melted yet.
