Abstract : Application of a new technique for determining the physical inventory of plutonium or uranium within the process line of a fuel reprocessing plant without a shutdown and flushout is described. The technique, which is analogous to an isotope dilution analysis, employs the unique isotopic compositions of different lots of fuel. One lot (the inventory) is displaced by fuel of another, different isotopic composition. By analyzing isotopically the product mixture containing the inventory, its quantity can be calculated, knowing the isotopic compositions of both lots of material. (Author)
