The US should build many Thorium fueled nuclear reactors like India and China. The US has a lot of Thorium reserves and in these reactors depleted Uranium (nuclear waste) can be re-used. Mankind will learn, that there is no waste and everything including nuclear waste is nothing else than precious raw material. This is article is nothing else than another roadblock to non-fossil fuel alternatives. If the US continues like this, it will be dependent not only for fossil fuels, but also for alternative technology from China and India. If there was such a resistance against air pollution during industrial revolution like there is currently against alternative energy, there would be no internet, no cars, no planes, probably we would be discussing the effects of the transcontinental railroad on turtle life and if this railroad should be built or not.

Here is a video about using thorium instead of uranium and how a liquid fluoride thorium reactor (LFTR) can burn, as fuel, our present nuclear waste:

Thorium alpha decay, safer, not hardly...
Thorium-232 has a half-life of about 14.05 billion years.
Uranium-235 has a half-life of 703.8 million years.
Caesium-137 has a half-life of about 30.17 years.

@ NoThorium,

It doesn't matter what the half life of thorium, or uranium isotopes is. They can all be destroyed in the LFTR.

The radioactive elements that cannot be destroyed by the LFTR are a problem, but not a serious one. Their half-lives are such that after only a few hundred years they are no longer radioactive enough to matter and their volume is low anyway.

Of course, for a given amount of atoms (i.e energy recovered), the radioactivity is inversely proportional to the half life. That's why Cesium and Strontium are potential problems, Iodine is an ACTUAL problem, and lantanides (and all after them) are no problem whatsoever.
