4. The Fukushima Daiichi Nuclear Power
Plant is a nuclear power reactor
located in the north east of Japan.
Composed of 6 boiling water reactors.
Introduction

6. 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
7. 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 Lost
8-10 hours later Station Batteries
wear out.
The Accident
7/16
8. SPREAD OUT OF RADIOACTIVE
CONTAMINATION IN ATMOSPHERE:
The radioactive contaminated
fallouts reached Korea by rain.
The air stream of the radioactive
fallouts 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.
The Accident

10. 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.
The Solution

11. SYSTEM DYNAMICS:
Is an approach to understand the behaviour
of complexe algorithme over time.
The Solution
data transferring center incorporated
with the mobile phone
Earth-quake
fast and continuous
randomized data gene

16. CONCLUSION
Thanks to technology we were able to control the contamination due to Fukushima accident,
But the big question is, can we expect the next?
