The purpose of the study is to analyze the temperature effect on the infinite multiplication factor for light water moderated High Enriched Uranium (HEU)-UAl4 and Low Enriched Uranium (LEU)-UO_2 lattices of the Ghana Research Reactor-1 (GHARR-1). To quantify the contribution of each component of the infinite multiplication factor with respect to temperature within the 20 to 140°C range, cell calculations were performed for the two MNSR typical lattices: the 90.2% enriched HEU-UAl_4 and 12.6% enriched LEU-UO_2 proposed fuel of the Ghana Research Reactor-1 (GHARR-1) using SCUBA, a locally developed FORTRAN 95 code for the calculations and analysis of temperature coefficients of GHARR-1. It was observed that at the beginning of life of the core, the temperature coefficient of the resonance escape probability and that of the thermal utilization factor, contributed significantly to the negative temperature coefficient of the infinite multiplication factor obtained for both fuels.
