The Dept. of Energy submits a license application to the U.S. Nuclear Regulatory Commission for the federal nuclear waste repository at Yucca Mountain, Nevada.
I will clearly qualify myself as someone who support nuclear power, be it in the form of fission reactors that we currently have, or development/research of fusion reactors (though not necessarily in the current trend). However, the central issue is still the waste generated by nuclear power plants, especially those in the US that are prohibited by law to be reprocessed, unlike those done in Europe and Japan. So baring a change in policy, having a safe place to store these nuclear waste is of utmost importance if support for that energy source is needed. That's why, after a lengthy study, the DOE is now able to apply to make the Yucca Mountain a repository site.
We'll see how it goes...
