U.N. sees progress in boosting post-Fukushima nuclear safety

VIENNA (Reuters) - Efforts to enhance global nuclear safety have advanced since Japan's Fukushima disaster struck exactly two years ago on Monday, the U.N. atomic energy chief said, vowing to help make nuclear power as "safe as humanly possible".

Yukiya Amano, a veteran Japanese diplomat, said virtually all member states of the United Nations' International Atomic Energy Agency (IAEA) with nuclear plants had completed so-called stress tests and had expanded safety measures.
