Bloomberg | Tokyo Electric Power Co. engineers tried to stabilize three nuclear reactors damaged by the biggest earthquake in Japan’s history after the plant was struck by a second explosion and as water levels dropped at one reactor, exposing fuel rods and increasing the threat of a meltdown.
The cooling system failed at the Dai-Ichi No. 2 reactor today, said Tokyo Electric, which runs the Fukushima nuclear plant 220 kilometers (135 miles) north of the nation’s capital. Fuel rods at the reactor may have melted after becoming fully exposed, Chief Cabinet Secretary Yukio Edano told reporters.
A hydrogen explosion occurred at the No. 3 reactor today, following a similar blast on March 12 at the No. 1 reactor that destroyed the walls of its building. The utility has been flooding the three reactors with water and boric acid to reduce the potential for a large release of radiation into the atmosphere following the March 11 earthquake-generated tsunami that smashed into the plant, disabling electricity supply and backup generators.
