SHORT-TERM AND LONG-TERM DAMAGE

Plant heavily damaged and unusable

Two workers killed by the tsunami. 37 injured including 2 suffering fromradiation burns.

Health consequences unknown to the remaining workers andresidents in the surroundings

1/6 of the amount of emissions by the Chernobyl accident

1,800 square kilometres of Fukushima Prefecture with potential dosesof 5mSv/year or more. 20 km exclusion zone inhabitable for decades

146,520 residents were evacuated and 60 died from complicationsrelated to the evacuation

Enormous economical repercussion

Evacuated population still suffer from stress about radiation exposurelevel and refusal to return of a great part

RESPONSIBILITIES AND CAUSES

Earthquake and tsunami foreseeable but no actions taken

The operator (TEPCO), the regulatory bodies (NISA and NSC)and thegovernment, failed to correctly develop the most basic safety requirements

Regulators negative attitude toward new advances, technology andprocedures from overseas

The regulators didnt take a strong position towards the operator

Regulators dependence of the ministry of economy. A pronuclear organization

Japanese mind-set. Corporatism and lack of logical reaction with unclearchain of command

MANMADE OR NATURALDISASTER? CONCLUSION

Although the trigger was a natural disaster of enormousproportions. The Fukushima accident was clearly manmade

It was the result of the collusion and lack of governancebetween the government, regulators and Tepco that resultedin inadequate decisions and action

The Japanese character influenced greatly the response to the

catastrophe

Fundamental reforms had to be taken covering the Japaneseenergetic industry, laws, regulators and operation procedures
