Analysis of central worths and other integral data from the Los Alamos benchmark assemblies
Description
We have compared theoretical calculations, based on ENDF/B-V and recent revisions, with integral data measured on the Los Alamos unmoderated critical assemblies Godiva, Jezebel, Flattop-25, and Flattop-Pu. The experimental data included in this analysis are multiplication factors k/sub eff/ and (in most cases) both fission rates and central-worth ratios for 235U, 238U, 237Np, and 239Pu. Based on this comparison, we conclude that there is a need for a new 235U evaluation, and increased accuracy is needed in certain integral measurements
