    Lawrence,

    I've taken the following tables from AECL's Intranet: (sorry for the poor
    alignment, but you'll get the idea, I hope. Note that this is only the
    information for U, not Th. As I have mentioned before, mixed Th/U fuels
    would extend our resources by quite a bit (~ a order of magnitude, I
    believe) by breeding fissile U-233 from Th-232.

    You are correct in that we have been swayed by incorrect logic in not
    pursuing nuclear power more vigorously.

    Glenn and other ASAPHILES:

    Does anyone here know of estimates of the available supplies of elements for

    producing power from fission reactors? I presume that this would be
    Uranium and
    Thorium.
            I find it ironic that the USA is largely depriving itself of this
    valuable energy
    source, when we developed it here, and the rest of the world is using it
    more than
    we are.
            In facing safety issues, we have been swayed by the "logic" that it
    would be
    better to kill 10 people in coal mine accidents and atmospheric
    contamination from
    burning coal, than to kill one person in a reactor accident. Somehow it
    would seem
    so "weird" do die from something Nuclear.
            The only person I know of in this country who has been killed by
    radiation from a
    fission reaction is Louis Slotin, who was performing a "critical mass"
    experiment at
    Los Alamos, soon after I left there in 1945. Slotin lived for several days,
    after
    first writing up the whole sad episode in his laboratory notebook,
    presumably with
    recommendations for performing such experiments by remote control, in the
    future.
            We need to take a realistic look at our options! That's my 3¢
    worth.
