Actually they are building a facility as we speak in the US that alledgedly can turn nuclear waste into a safe and useful material. It is being built for other materials, but they claim they can handle nuclear waste.
I have a variety of reasons for supporting clean coal liquafaction...primarily economic. We don't need to import the coal; we have an over 250 year supply. All mining, processing, transportation, distribution, refining, sales, and marketing costs would create huge numbers of jobs in our economy and ALL of that money would stay in the USA.
There is no such benefit from nuclear. Given the exploration into clean nuclear, coal will buy us lots of time to get the nuclear equation right before we launch into that direction. (PS: aren't the major sources of uranium overseas? Therefore, why trade one despotic cartel for another one?)
They also claimed that they could deliver oil at about $15 a barrel (it's closer to $80) and that the process using turkey offal would be odor-free (it reaks to high heaven for miles.)
