International Atomic Energy Agency Director General Yukiya Amano said Saturday that Japan was ''still far from the end of the accident'' that hit a nuclear plant in Fukushima Prefecture, according to a report by the New York Times.

The report said that, Amano was not criticizing Japan's response under extraordinary circumstances but more efforts should be done to put an end to the accident.

Chief nuclear inspector said his biggest concern now centered on spent fuel rods sitting in open cooling pools atop reactor buildings of the quake-hit Fukushima Daiichi plant, about 220 kilometers northeast of Tokyo, the report added.

Mr. Amano said that he believed that the Japanese authorities were not withholding information, but that his recent trip back to Japan had been intended to secure from Prime Minister Naoto Kan a commitment to what he called full transparency.
