Yukiya Amano, Chief of the U.N.’s nuclear energy agency reveals that Japan is trying its best to cool the nuclear reactors after its cooling systems failed following devastating earthquake and tsunami in the country. The nuk chief stated this after observing the situation in Tokyo and a talk with the Japanese Prime Minister Naoto Kan.

The UN diplomat says that the accident at the Fukushima Dai-ichi nuclear plant was more serious that what he predicted. The Japanese authorities are still trying to cool the reactor, whereas the unprecedented rise in temperature at reactors is exposing the spent fuel rods that are lying in empty pool in the reactor.

Japan has been offered assistance for assessing the dangers of Fukushima by the United States. It has also recommended a 50-mile evacuation zone for precautionary measure to avoid effects of harmful nuclear radiations from the plant, revealed the US Nuclear Regulatory Commission Chairman Gregory Jazcko. To regain control over the plant, a new power line is being laid to the plant to restore cooling system for the reactors, however its operators, Tokyo Electric Power Co. has already missed the deadline it set to complete the restoration work.

The Group of Seven industrialized nations has also offered to help Japan in this need of crisis and reinstall all infrastructure that has been devastated by the Friday earthquake.

However this effort would be focused on intervention on the currency market to weaken Japanese Yen and help Japan to gain from its exports.
