Official: 2nd Japan nuclear reactor at risk of explosion
Problems also reported at three other reactors; 22 people have been contaminated with radiation


Japan was fighting to contain what could be the world's worst nuclear disaster in 25 years with the government warning there could be an explosion at a second reactor crippled by Friday's devastating earthquake.

More than 170,000 people have been evacuated from the area around two nuclear power plants in Fukushima as a precaution, officials said Sunday.

It was also confirmed that 22 people had been contaminated by radiation.

There is believed to have been a partial meltdown of the fuel rods following an explosion and leak Saturday from the No. 1 reactor at the Fukushima Dai-ichi power plant, 150 miles north of Tokyo.

And engineers were pumping in seawater in an attempt to prevent the same thing from happening at Dai-ichi's No. 3 reactor.

"At the risk of raising further public concern, we cannot rule out the possibility of an explosion," Chief Cabinet Secretary Yukio Edano told a news briefing.

"At the risk of raising further public concern, we cannot rule out the possibility of an explosion," Chief Cabinet Secretary Yukio Edano told a news briefing.


..He said if there was an explosion, "there would be no significant impact on human health."

Edano said neither Fukushima Dai-ichi reactor was near the point of complete meltdown, and he was confident of escaping the worst scenarios.

A meltdown at the No. 3 reactor could be more serious than at the other reactors because it is fuelled by both plutonium and uranium, BBC News reported. The others have only uranium fuel.


Moved quickly
Edano said they had moved more quickly to deal with the potential problem at the No. 3 reactor, in apparent acknowledgement that the authorities had moved too slowly on Saturday.

"Unlike the No.1 reactor, we ventilated and injected water at an early stage," he said. People living within about 12 miles of the Dai-ichi plant have been evacuated.

Nuclear plant operator Tokyo Electric Power, known as TEPCO, also said Sunday it was preparing pressure reducing measures for the nearby Fukushima Daini power station, where four reactors were shut down due to earthquakes.

Releases of air with radioactive material were being considered for Daini units 1, 2, and 3. People living within six miles of that plant have been evacuated.

GE-designed reactors in Fukushima have 23 sisters in U.S.
TEPCO said radiation levels around the Dai-ichi plant had risen above the safety limit but that this did not mean an "immediate threat" to human health.

Japan earthquake Report: 2nd Japan nuclear meltdown likely under way
A partial meltdown is likely under way at a second quake-stricken nuclear reactor while efforts are under way to stop a meltdown at another, a top Japanese official says.

The disaster prompted an angry response from an anti-nuclear energy NGO in Japan which said it should have been foreseen.

"A nuclear disaster which the promoters of nuclear power in Japan said wouldn't happen is in progress," the Citizens' Nuclear Information Center said. "It is occurring as a result of an earthquake that they said would not happen."

A Japanese official said there were 190 people within a six-mile radius of the Dai-ichi plant when radiation levels rose and 22 people have been confirmed to have suffered contamination.

The severity of their exposure, or if it had reached dangerous levels, was not clear. They were being taken to hospitals.




Radiation risk from nuclear plant seen as worrisome

..Any complete meltdown — the collapse of a power plant's systems and its ability to keep temperatures under control — could release uranium and dangerous contaminants into the environment and pose major, widespread health risks.

Pouring sea water into a reactor likely renders it unusable, said a foreign ministry official briefing reporters.

'Hail Mary pass'
Robert Alvarez, senior scholar at the Institute for Policy Studies and former senior policy adviser to the U.S. secretary of energy, told reporters that the seawater was a desperate measure.

"It's a Hail Mary pass," he said.
