I have been an advocate of thorium based nuclear power for a long time. There are certain advantages that thorium based nuclear technology has over uranium and plutonium systems that make it appealing, as long as the nuclear genie is out of the bottle anyway. Others have written about this and there is no point in my wasting bandwidth on it here.  Fort St. Vrain Generating Station, one of the very few HTGR Thorium plants ever operated in the US sat a half hour from here from 1979 to 1989. As prototypical operations go, the plant had a history of upsets and unforeseen complications and was decommissioned after a decade of sub-commercial output. Eventually the plant was converted to a natural gas turbine plant and runs to this day in that capacity.

So it was of interest to learn that the venerable European company Solvay has teamed up with AREVA to develop thorium technology. Uranium and rare earth processing, as well as other minerals produce side streams enriched in thorium.  According to the link, both players have been accumulating inventories of thorium.  Hmmm. What could they be up to…?
