This paper provides the results of criticality analysis of uranium fueled, polyethylene-moderated/reflected thermal spectrum cores performed at the solid moderated cores of Kyoto Univ. Critical Assembly. A wide variety of neutron spectra as well as different effective uranium enrichment have been realized in the experiments. The analyses have been performed by continuous energy Monte Carlo code MVP using cross section data based on JENDL-3.3, ENDF/B-VI.8 and JEFF3.1 libraries. All libraries gave the C/E values within {+-}0.5% to unity for most cases. Enrichment dependence and spectrum index dependence of the C/E values have been observed. (authors)
