Computational Approach for Evaluation of Nuclear Data IincludingCovariance Information

A computational approach was developed for the evaluation of nuclearcross-section data taking into account experimental data and results ofnuclear model calculations. A set of computer programs, called BEKED, wasdeveloped to perform the processing of experimental data, provide the runsfor the cross-section and covariance data calculations, and perform theglobal evaluation of nuclear data. The calculation of covariances arecarried out using different approaches including the generalizedleast-squares method and the Monte Carlo method developed by D.Smith, whichtakes into account both experimental and nuclear model uncertainties.Presently, the BEKED approach integrates the nuclear model codes TALYS andALICE/AS, as well as other codes employing e.g. the intranuclear cascadeevaporation model.
