FUKUSHIMA, JAPAN: An explosion blew the roof off an unstable reactor north of Tokyo on Saturday, Japanese media said, raising fears of a disastrous meltdown at a nuclear plant damaged in the massive earthquake that hit Japan.
The 8.9-magnitude earthquake -- the strongest ever recorded in Japan -- sent a 10-metre tsunami ripping through towns and cities across the northeast coast. Japanese media estimate that at least 1,300 people were killed. ( Read: Japan braces for N-reactor meltdown )
Jiji news agency said there had been an explosion at the stricken 40-year-old Daichi 1 reactor and TV footage showed vapour rising from the plant, which lies 240 km (150 miles) north of Tokyo.
The blast came as plant operator Tokyo Electric Power Co (Tepco) worked desperately to reduce pressures in the core of the reactor that -- if not contained -- could lead to a release of radiation into the atmosphere.
"An unchecked rise in temperature could cause the core to essentially turn into a molten mass that could burn through the reactor vessel," risk information service Stratfor said in a report.
