Nuclear crisis in fukushima not only had a tremendous impact on the Japanese nuclear power industry,fuel import and the cost of power generation,and national nuclear strategy,but also induced national debate on nuclear existence.Nevertheless,effect that nuclear crisis and its secondary disasters in fukushima had on Japan's energy security,is not a structural crisis caused by energy shortage,but a flexible,temporary profitable crisis.Great changes will not occur in Japan's energy security strategic framework.Japan will not completely abandon nuclear power industry.And nuclear energy will remain as one of the main energy supporting Japan's economic development in the future.But some changes will take place in the energy target,safety orientation,action content and other aspects. <<
