Here is a recent article I found that talks about the disposition of 3200 tonnes of thorium that was in the US stockpile. The thorium from Curtis Bay alone (2700 tonnes) would produce all the electricity the US needs for eight years, if used in a liquid-fluoride reactor. My own comments are in paretheses and italics.
Curtis Bay Thorium Nitrate Now in Nevada

The Defense National Stockpile Center’s thorium nitrate disposition project achieved a significant milestone in May when the last shipment of the radioactive material departed the Curtis Bay Depot. All material from the Curtis Bay, Md., storage site is now in Nevada and has been buried at the Department of Energy’s Nevada Test Site.
