COVFILS is a 30-Group Covariance Library. It contains neutron cross sections, and their uncertainties and correlation in multigroup form. These data can be used, in conjunction with sensitivity information, to estimate the data-related uncertainty in calculated integral quantities such as radiation-damage or heating.
A short retrieval program, COVARD, and the result of a sample execution of the program are included in the package. COVARD reads the multigroup cross-section and covariance data in the condensed ENDF-like format of COVILS and transforms the data into engineering format (with zeros present explicitly and groups reordered to the conventional high-to-low order). This version of COVARD retrieves and prints the cross sections and the covariance matrix for a single "wired-in" reaction pair. The output resulting from executing COVARD, as written with no input required, is included in the code package.
