The Washington Post is now reporting that the remaining workers at the Fukushima Daiichi nuclear plant are being evacuated after radiation levels have risen too high.
The workers had been furiously trying to keep nuclear fuel rods cool enough to prevent a full meltdown. A meltdown could potentially release thousands of tons of radioactive material into the air.
Earlier, fire again broke out at the Fukushima Daiichi nuclear power plant in northeastern Japan, according to press reports.
The news of the second fire comes after officials said an earlier fire was under control. The cause of the latest fire was not clear.
Officials at the Tokyo Electric Power Company said they would think about using helicopters to pour water onto spent uranium rods held in a rooftop container. The rods are radioactive and could be as dangerous as rods inside the reactors if not kept in cold water, according to The New York Times.
It is not clear yet just what the second fire means for the government's and electric company's efforts to keep the plant from spiraling into a meltdown after the devastating and deadly 9.0-magnitude earthquake and tsunami rocked Japan last week. But on Tuesday, the government told residents living within a 20-kilometer radius of the plant to evacuate and people within a 30-kilometer radius to stay indoors.
