[2O10] Generation of multi-group cross sections and covariance data based on JENDL-4 for the SCALE code system

Keywords:Multi-group cross sections, Covariance data, SCALE, JENDL-4, AMPX

For the SCALE code system we have created a multi-group cross section library (AMPX format) and corresponding covariance data (COVERX format) using the JENDL-4 evaluated nuclear data. Calculations indicate a satisfactory performance of the library. Validation calculations are being performed.
