Nuclear Energy, Agree?

According to DOE, Over 20% of electricity in the USA is obtained from nuclear power. It is, true, a radiation emitting energy, however, certain sources have agreed that the rate of radiation of obtained nuclear power will decrease significantly in the coming years. (Tests are being done about fusion rather than fission processes)

And FYI, Bush administration supports and funds Nuclear Energy.

As an energy source, what are your opinions about it?
