Big problem : Japanese Energy Condition

Presentation on theme: "Big problem : Japanese Energy Condition"— Presentation transcript:

1 Big problem : Japanese Energy Condition
■ Topics on TES from Japan after the 7２th EXCO Meeting (Aibling, Germany)　 Big problem : Japanese Energy Condition ・Destroyed　Nuclear Power Plant (4 Reactors) by “Earthquake and Tumani” on March 11, 2011 We can not to operate NPP after Periodical Inspection because of Social Condition ・Every Nuclear Power Plants in JAPAN sttoped on May 5, 2012 (54 Reactors : 　total 　 million kW)

2 Transitions in the Electric Power supply by 10 Japanese Utilities
