The radioactive elements in fossil fuels is less of a problem than you think, because a) coal plants, etc. have to filter these out (at least in germany they do) b) they have short half-times. And storing the radioactive waste for a few thousand years is by no means an easy/cheap task.. just look at the two experimental radioactive waste sites in germany.. both turned out to be a huge disaster in less than 100 years. Also I am not convinced that breeder reactors help you that much to get rid of thousands of tons of radioactive reactor assembly.
