At approximately 11:01am, an explosive sound followed by white smoke 
occurred at the reactor building of the Unit 3. It was believed to be a 
hydrogen explosion.

According to the parameter, it is estimated that the reactor containment 
vessel remains intact. However, the status of the plant and the impact 
of radioactive materials to the outside environment are presently under 
investigation. 

Some workers have sustained injuries. Ambulances are on their way to care 
for them.

TEPCO continues to take all measures to restore the safety and security of 
the site and are monitoring the site's immediate surroundings.
