Abstract

This paper documents the results obtained in an adjustment study of cross section parameters as well as keff responses of 19 spherical plutonium critical assemblies, utilizing the new TSURFER (Tool for Sensitivity/Uncertainty Analysis of Response Functionals Using Experimental Results) module. Special attention was devoted to the sensitivity of the results to the available variance-covariance data and supplements for the responses and parameters.
