BERLIN — With the crisis in Japan raising fears about nuclear power, Germany and Switzerland said on Monday that they would reassess(再次评估) the safety of their own reactors([核] 反应堆).

Doris Leuthard, the Swiss energy minister, said Switzerland would put off plans to build nuclear plants. She said no new ones would be permitted until experts had reviewed safety standards.

Germany will put off “the recently decided extension of the running time of German nuclear plants,” Chancellor Angela Merkel told reporters. “This moratorium(延缓)will run for three months and it will allow for a thorough examination of the safety standards of the county’s 17 nuclear power plants.

The European Union called for a meeting on Tuesday of nuclear safety authorities to assess Europe’s preparedness.

Germany’s foreign minister, Guido Westerwelle, called for a new risk analysis of the country’s nuclear plants, particularly regarding their cooling systems. He is the leader of the Free Democratic Party, which strongly supports nuclear power.

A previous government, led by the Social Democrats, passed a law in 2001 to close all the country’s nuclear plants by 2021. But Mrs. Merkel’s government changed that decision last year to extend the lives of the plants by an average of 12 years.

In Switzerland, Doris Leuthard said she had already asked to analyze the exact cause of the problems in Japan and draw up new or tougher safety standards “particularly in terms of seismic(地震的,与地震相关的) safety and cooling.”

In Russia, the Prime Minister said his government would “draw conclusions from what’s going on in Japan.”
