Abstract

The aim of this paper is the comparative study of WIMS library group constants generated from ENDF/B-VI and JENDL-3.3 evaluated nuclear data files. The WIMSLIB group constants have been generated from ENDF/B-VI and JENDL-3.3 through NJOY'99 for 20Ca, 12Mg, 15P, 16S, 14Si, 22Ti, and 23V. The GROUPR output was processed by WIMSR to produce the WIMSLIB group constants. The parameters compared are slowing down power/lethargy widths, transport cross-section, absorption cross-section and Goldstein–Cohen λ parameters. WIMS library generated from ENDF/B-VI and JENDL-3.3 have good agreement in general but some significant points of disagreement also exist. These observations can be used as inputs for the WIMS update library of TRIGA Mark-II research reactor and also for the ENDF/B-VI and JENDL-3.3 data verification tasks.
