IAEA chief defends nuclear energy

The head of the International Atomic Energy Agency, speaking at the site of the Chernobyl nuclear power plant explosion, says that accident and the Japanese nuclear crisis do not undermine the value of nuclear power.

Yukiya Amano spoke Wednesday at the site of the world's worst nuclear accident. He was accompanied by U.N. Secretary-General Ban Ki-moon and Ukrainian President Viktor Yanukovych.

Amano says many countries will continue to find nuclear power an important option for energy diversification but that the global community must do its utmost to ensure its safety.

His visit comes just days before the 25th anniversary of the Chernobyl disaster.
