THE ACCIDENT

5/16

WHAT HAPPENED?

Friday March 11th @ 2:36 pm local

Magnitude 9.0 earthquake hits the pacific, 231 miles northeast of Tokyo.

Quake is fifth largest in the world (since 1900).

Generated a 14m Tsunami

The Accident

6/16

AS A RESULT :

Earthquake Earthquake Caused Automatic Shutdown of 3 Operating Units Offsite Power Lost

14m Tsunami (less than 1 hour later)

All Emergency Back-up Power Lost8-10 hours later Station Batteries wear out.

The Accident

7/16

SPREAD OUT OF RADIOACTIVE CONTAMINATION IN ATMOSPHERE:

The radioactive contaminatedfallouts reached Korea by rain.

The air stream of the radioactivefallouts had come in from the southern regions by the air circulations.

=> The wind speed and direction has too many uncertainties to predict, in a very short time interval, the contaminated area.

CLOUD COMPUTING:

The cloud computing is developed for the fast and reliable communications using the mobile phone.

Therefore, the data processing is performed by the cloud computing concept where the fast and reliable data transferring is easily done.
