Isotopic compositions of inventory designations, (open quote)mixed fission product(close quote) and (open quote)mixed activation product(close quote)

摘要

The Area G Performance Assessment requires that the entire inventory be specified in terms of specific nuclide activities. The inventory data base has historically allowed some less specific inventory designations including Mixed Fission Products (MFP), Mixed Activation Products (MAP), several Material Type (MT) designations and others. This report describes the assignment of specific nuclide activities from the listed activity amounts in two of the inventory data base categories, MFP and MAP. The MFP nuclide assignment is based on standard fission product yield data and normalized to total activity at two years post-fission. The MAP assignment is based on site-specific analyses conducted by the major generator of the activation products at Los Alamos, the LAMPE.
