Fukushima Daichi Unit 4 Fire Thought to Have Released Radiation

WNN reports that Prime minister Naoto Kan confirmed a fire burning at unit 4, which, according to all official sources, had never been a safety concern since the earthquake. This reactor was closed for periodic inspections when the earthquake and tsunami hit, therefore did not undergo a rapid and sudden shutdown. It was of course violently shaken and subject to the tsunami.

Kan’s spokesman Noriyuki Shikata said that there had been “a sign of leakage” while firefighters were at work, “but we have found out the fuel is not causing the fire.” The fire is now reported extinguished.

Further evacuation ordered

Kan has requested that evacuation from a 20 kilometer radius is completed and those between 20-30 kilometers should stay indoors. He said his advice related to the overall picture of safety developments at Fukushima Daiichi, rather than those at any individual reactor unit.

Shikata added that radiation levels near the reactors had reached levels that would affect human health. It is thought that the fire had been the major source of radiation.
