Upside down of nuclear myth into nuclear reality
The earthquake hit Kashiwazaki-Kariwa nuclear power station (7.8 GWe) on
July 16th 2007 exposed opposite aspect of nuclear power
- from “climate solution” to “climate risk”
- from “cheap power” to “economical risk”
- from “supply security” to “supply risk”
- from “safety myth” to “unsafe reality”
