Governments reexamine nuclear power plants as Japan battles to contain a nuclear meltdown

Anxiety over Japan's quake-stricken nuclear reactors has caused governments to review their energy policy.

U.S. Sen. Joe Lieberman (I-Conn.), chairman of the Senate Homeland Security and Governmental Affairs Committee, said Sunday on CBS television's Face the Nation: “I don't want to stop the building of nuclear power plants, but I think we've got to kind of quietly put, quickly put, the brakes on until we can absorb what has happened in Japan.” WATCH:

Switzerland’s energy minister said Monday that the country is suspending approvals to replace three of its nuclear power stations, Reuters reported.

In Germany, Foreign Minister Guido Westerwelle said Monday that individual nuclear power plants could be shut down on safety grounds, the Wall Street Journal reported. If German reactors were found to have inadequate cooling systems, the facilities would be shut down and upgraded, Westerwelle said.

Russian Prime Minister Vladimir Putin said Russia has no plans to change its domestic nuclear energy program, Reuters reported.

New hydrogen blast at troubled plant injures 11; U.S. ships move away from plant

A new explosion ripped through the quake-stricken nuclear plant in nuclear Japan Monday, injuring 11 people, one of them seriously, Chico Harlan and Steven Mufson reported.

The hydrogen blast was reported at unit 3 of the Fukushima Daiichi plant as hundreds of people were tested for radiation exposure and the death toll in Japan continued to climb. The blast raised new fears of a possible nuclear meltdown. A Japanese government official separately said that a third reactor at the six-reactor facility had lost its cooling capacity.

The explosion at unit 3 did not damage the core containment structure, but did prompt Japan’s nuclear agency to warn those within 12 miles to stay indoors and keep air conditioners off.

The U.S. Seventh Fleet said Monday it had moved its ships and aircraft away from the plant after discovering low-level radioactive contamination.

The fleet said that the radiation was from a plume of smoke and steam released from the Fukushima Daiichi plant.

The aircraft carrier USS Ronald Reagan was about 100 miles offshore when its instruments detected the radiation. The fleet said the dose of radiation was about the same as one month’s normal exposure to natural background radiation in the environment.
