       Dear Mr. Secretary:

           Xhe adequacy of the uranium resource base has become
       a significant issue in the discussion of the long-term
       role of nuclear power. The necessity for and timing of
       reprocessing and breeders are closely related to the
       adequacy of the domestic and world uranium resource base.

       In the courseo     s workw   have found lqai-TT--des

       uranium-bearn oeto extract U308 (yellow cake). .A

            The widely-cited Ford/MITRE study (Nuclear Power:
       Issues and Choices), for example, which appears to have
       had significant influence on Government nuclear policy,
       used uranium demand at the mill, not     2,ne mine. A Depart-

       i-e-sa-d D-OEwas considering introducing mill losses. He
       also said that the International Nuclear Fuel Cycle Evaluation
       (INFCE)  r  a   which is assessing future prospects for
       nuclear power, uses mill demand in its assessment of the
       emand on the uran-i--um resource base. W        t is
       by examining the data used as input for the INFCE assessments,
       and we indeed found that no correction is being made for
       milling losses.

            Since 1966, milling losses have steadily increased,
       reaching 8.2 percentir iS177 This is more than double
       the 1966 losses. At the same time uranium ore grade has
       fallen by a third to 0er155p f-i.17pounc[-T3OW Per
