Obama aides offered few details about the president’s remarks.

During January’s State of the Union address, Obama said he wanted 80 percent of US electricity to be generated by clean energy sources, including nuclear power, by 2035.

Nuclear power has come under more intense scrutiny in recent weeks after an earthquake and tsunami in Japan severely damaged a nuclear power plant there.

Despite the uncertainty at that facility, Obama says he remains committed to developing nuclear power in the US.
