Japans top government spokesman says the countrys tsunami-ravaged nuclear plant must eventually be scrapped. Chief Cabinet Secretary Yukio Edanos comment on Sunday was the first word from the government that the Fukushima Dai-ichi nuclear complex will have to be closed once its overheating reactors are brought under control. Closing the plant is inevitable, since the seawater that emergency crews are using to cool the reactors is corrosive, rendering key parts of the complex unusable. Mr Edano says the plant will be in no condition to be restarted.
