Abstract

Resonance parameter representations of nuclear data are used by processor codes to compute quantities needed for criticality safety and other nuclear applications. Usually these calculations also require the associated parameter covariance matrices (PCMs) that contain both the variances of resonance parameters and the correlations between parameters. The SAMMY code is widely used to fit neutron cross section data to obtain both resonance parameter representations and the corresponding PCMs, which are output to binary files. We have written a code, RADCOP, that facilitates the manipulation and visualization of information from SAMMY PCMs. RADCOP produces both one- and two-dimensional correlation plots that permit one to quickly trace the important off-diagonal correlations. ENDF File 2 and File 32 files for the Reich-Moore representation may be output.
