VIENNA - The reactors at Japan's crippled Fukushima atomic power plant are now "essentially stable", the UN nuclear chief said on Monday, six months after the world's worst nuclear disaster in a quarter of a century.
Yukiya Amano, director general of the International Atomic Energy Agency (IAEA), said the expectation was that a "cold shutdown" of all reactors would be achieved as planned.
"The plant operator and the Japanese authorities have been working hard to regain full control of the situation and have made steady progress in the past six months," he told the 35-nation governing board of the Vienna-based UN agency.
"The situation at the site remained very serious for many months. The agency's assessment now is that the reactors are essentially stable," he added.
