Is Al Gore For Nuclear Power?

I've always said that I won't take global warming alarmists seriously until they drop their opposition to nuclear energy.

Al Gore seems to have relaxed his opposition to nuclear energy. He now only questions its sustainability.

Gore says investing in uranium mining also comes down to sustainability. Although concerned about nuclear waste and the possibility of spent fuel rods falling into the wrong hands, he says he is not "reflexively against" nuclear energy.

Does that mean he's in favor of fast breeder reactors?
