Kerry's nuclear positions in conflict?

JunkScience.com's Steven Milloy asserts that there is a major contradiction in John Kerry's position on nuclear power:

Kerry's Web site states that "nuclear power can play an essential role in providing affordable energy while reducing the risk of climate change." His aides also say he is for nuclear power.

So far, so good. But then on a recent campaign stop in Las Vegas — about 100 miles away from the planned Yucca Mountain (search) site for the long-term disposal of waste from nuclear power plants — Kerry said, "When I'm president of the United States, I'll tell you about Yucca Mountain: Not on my watch."

The realty of the matter, however, is that you can't be "for" nuclear energy (search) but "against" Yucca Mountain.

Coastal communities near Diablo Canyon and San Onofre are likely counting on Kerry to flip-flop on Yucca Mountain were he elected.
