Japan’s nuclear crisis intensified yesterday as authorities raced to combat the threat of multiple reactor meltdowns, while investors feared a share market crash.
More than 170,000 people have been evacuated from the northeastern coast where fears spread over radioactive contamination.
Nuclear plant operators were frantically trying to keep temperatures down in a series of nuclear reactors, including one where officials feared a partial meltdown could be happening yesterday.
Chief Cabinet Secretary Yukio Edano also said that a hydrogen explosion could occur at Unit 3 of the Fukushima Daiichi nuclear complex, the latest reactor to face a possible meltdown.
That followed Saturday’s blast in the power plant’s Unit 1, as operators attempted to prevent a meltdown there by injecting sea water into it.
A spokesman from Japan’s nuclear agency, Ryo Miyake, said that up to 160 people, including 60 elderly patients and medical staff who had been waiting for evacuation in the nearby town of Futabe and 100 others evacuating by bus, might have been exposed to radiation.
Japanese Trade Minister Banri Kaeda warned that the region was likely to face further blackouts, and power would be rationed to ensure supplies to essential facilities.
The government doubled the number of troops pressed into rescue and recovery operations to about 100,000 from 51,000, as powerful aftershocks continued to rock the country.
The impact on Japan’s economy has been disastrous.
