Tokyo Electric Power Co . must speed up plans to cover reactors at its crippled nuclear plant and drain tainted water to prevent more radiation leaks as Japan’s typhoon season approaches, engineering professors said.
Robots sent into three buildings at Japan’s crippled Fukushima Dai-Ichi nuclear station detected radiation too toxic for humans after the plant operator set out a plan to end the crisis in six to nine months.
Japan’s Prime Minister Yoshihiko Noda said the Fukushima nuclear reactors have been brought to a state of cold shutdown, a disputed milestone that will likely allow the return of some evacuees and eventual dismantling of the plant.
Tokyo Electric Power Co. said critical units of its Fukushima nuclear plant withstood shaking from the March 11 earthquake, Japan’s strongest on record, before being swamped by the tsunami that followed.
Two Japanese scientists and an American researcher whose work paved the way for new medicines and plastics won the Nobel Prize in Chemistry for developing tools to synthesize carbon-based molecules found in nature.
The head of Tokyo Electric Power Co. was refused a meeting with the governor of Fukushima, where the utility is battling radiation leaks from its atomic station at the center of Japan’s worst civilian nuclear disaster.
