In order to find the thermal utilization in slightly enriched uranium, light water moderated lattices, we have been measuring the flux variation over individual lattice cells. So far measurements have been .750 inch diameter rods of 1.027% enrichment, and with .600 inch diameter rods of 1.3% enrichment. This memorandum includes results of the latter measurements; the former are reported on BNL log C - 6687. In this phase of the study we have measured flux plots at water to fuel volume ratios of 4:l, 3:l, 2:l, 1.5:l, and 1:1. There is in addition to the clean water measurements a set which was made with various concentrations of P2O3 dissolved in the moderator. All these are reported here.
