Evaluation of Savannah River Plant shuffler calibration standards

Technical Report ·
DOI:https://doi.org/10.2172/6554385· OSTI ID:6554385
Six chemistry and three nondestructive assay (NDA) measurements have been made to provide information on the /sup 235/U content of twelve standards cut from a cylinder of uranium-aluminum alloy to be used in calibrating the /sup 252/Cf shuffler. These data have been evaluated to produce a set of uranium mass estimates and associated uncertainties for the standards by means of least squares techniques. Longitudinal fluctuation in uranium density is modeled, both by linear splines and by polynomials, and the two methods are compared. Also, a method is given for assessing the accuracy of the measurement uncertainties initially provided.
