Explosion at Fukushima 1: Several Workers Injured

12 March 2011, 16:52

According to the Fukushima office of Tokyo Electric Power, a sound of explosion was heard at Unit 1 of the Fukushima 1 Nuclear Power Plant around 3:30 PM.  A plume of smoke was seen ten minutes later.  Several workers have been reportedly injured.

The Fukushima office says that the smoke appeared to arise between the reactor building and the turbine building.  However, it has been unable to confirm its exact location.  The number of the injured, the degree of their injuries, any change in the measurement of radioactivity outdoors, whether or not the reactor container has been damaged are all unknown.  The water level of the reactor has not shown any abnormal decrease.  Two Tokyo Electric Power workers, and two employees of the company’s collaborator, appear to have been taken to hospital.
